You’re using DSP wrong! Top 5 DSP Misconceptions
HTML-код
- Опубликовано: 27 авг 2024
- A DSP, or Digital Signal Processor, allows us to control time alignment, crossovers, and Equalizers for each speaker in a car audio system. This allows us to fully tune a car audio system to optimize performance, but there are some common misconceptions about DSP that people don't really understand. Let's clear them up!

Car Audio Fabrication - Master Car Audio - Design, Build, Install
A huge misconception in car audio is not to use loudness and take the *Fletcher-Munson curves / Equal-loudness contour* into consideration (acoustically) because, we need those curves to listem to all the frequencies at the same levels so *it sound "flat"* to our ears. Once your sound it's properly adjusted and with loudness on, you use the EQ to cut (no to boost) the excess frequencies.
Being able to set crossovers digitally and with exact slopes vs analog potentiometers was well worth it to me. Even if I'm not going in and doing much EQ or time delay stuff. The accuracy and the ability to choose my slope strength and type, and the fact that I didn't have to deal with buying passive crossovers/bass blockers/etc, yeah. Cheap $120 DSP made it worth it even if I'm not going full audio tune. I could immediately hear the difference once I installed it and had it take over for handling crossovers.
The 80/20 rule definitely applies to car audio. Where we can get about 80% of the best quality by spending about 20% of total possible cost and time, whereas to get that final 20% of quality it'll require an additional 80% of not just money, but time/effort.
Nice video!
I've been using active crossovers for 5 years
To protect the tweeters I use capacitors bigger than the designed freguency cut, something about 8 ir 10 micro farad, is more than enough to cut low frequencies and noises from amps and system.
Never had problems
One of the biggest downfalls of the audio control product is that the crossovers are global...meaning all the "different tunes" you create have to share the same crossover slopes and values. So if you have multiple tunes for different reasons like top and top down on a convertible, or a Jeep top on and no top, the crossovers have to remain the same. LITERALLY NO OTHER COMPANY IN THE INDUSTRY DOES THAT, THAT'S STUPID. If you want more volume with the top off or down, you are going to have to readjust your gains, crossover points, and even make some EQ adjustments. You know that to go louder and to get less distortion you have to set your crossover points higher.
They need to change that...and catch up with the industry, or make a running change in their products or software.
Great videos by the way! 🤘🇺🇲
I have the Twk-88 DSP (along with my RD900/5) and I love it. I wasn't introduced to AudioControl until after my install in my car was done months later. That said, DSP makes a world of difference and with the right setup... it can almost sound like a studio, but in your car. I said almost. My Challenger sings so wonderfully now. Later when I am going to check on upgrading I will definitely check out AudioControl (though JL Audio is treating me well so far).
Your twk is better than the audio control for one reason: the twk has parametric eq, the audio control does not. Parametric is always better when it comes to tuning to a flat response
@@redacted6115Audio Control has EQ tuning
Audiocontrol needs to do some tweaking to their dsp. The 25hz lowpass filter needs to be removed, more crossover options for fine tuning, Bluetooth auto reconnect, to name a few. Mine has been driving me nuts since I bought it last year
AudioControl need to do a lot more than that to improve their DSP, I found a tons of bugs while using it, l sent them a list of stuff to fix, and suggestions for improvement and I really hope they will come up with some stuff fixed in a new firmware because the product at it's core is really good.
@@Domaudeo I spoke to them several times over these issues. They told me that most of this stuff won't be fixed in an update, but would be done when the next generation comes out. We are stuck with a flawed product while they keep making sells and expect us to spend another $800 for another one
@@bartowflorida I fully agreed. And even if you look elsewhere, other DSP products are not perfect either... That's a bit of a shame because it's not THAT hard to build a product that would be near perfect. Car audio did not evolve that much and the feature enthusiasts needs are the same since years.
@@bartowflorida Do you think the guy in the videos is paid to push DSP equipment? I've never used one and never felt any need for one personally. I don't really see the gains justifying the cost. The gains are minor and negligible in my view.
@@sleepingwarrior4618 dsp are definitely worth it. Crossover slopes, attenuation, signal corrections, input and output gains. I'd say the advantages are far more than negligible
Audiocontrol really needs to implement a Parametric EQ. You get that in there and these DSP's are gonna be worth their money.
Do they only have graphic eq? Those are nearly worthless for tuning a car. Parametric eq is a MUST.
Not to get into the parametric vs graphic EQ “which is better” argument, but not one in a thousand car drivers have the experience using high quality parametric EQ that a professional electric guitarist or sound engineer would have. Even the majority of audio installers would not know how to adjust para EQ optimally, and the results would likely suffer.
Graphic EQ better fits the target audience for AudioControl products. This company is not chasing highly experienced sound studio crowd. This is consumer grade merchandise targeted at above average audio consumers, not studio pros. The price reflects that market position.
I'm a little confused, as quite a few Pioneer receivers have not only a custom EQ setting, but also crossover adjustments for subwoofer and full range. I get that this example DSP is far more advanced, but for beginners on a budget, the receiver controller isn't completely horrible.
That is a lot better than nothing but sending a full-range signal to a driver that cannot physically play that sound or play without distortion is the real point of DSP. You 100% should be sending only subfrequencies to a subwoofer. Imagine installing lovely tweeters to only play a full-range signal through them and they sound like crap without DSP or a physical crossover that restricts the wrong frequencies from getting to it.
@@kaffeewerks9609 That's just it, quality pioneer receivers have a built-in DSP, it's just not as high quality as the one shown in the video. So even the receiver can split 5 channels.
This video is great, a really straightforward and no nonsense look at DSPs, nicely done 👍 I love using the Thomann 4x4 mini DSP for my portable sound system builds, it’s a good solution for a compact setup
Good Explanation ! My fav channel!
From Malaysia.
OMG, I'm going to get in so much trouble from this video. Great stuff. I really want to use one combined with an amplifier. Awesome video. Thanks.
I’ve been using the JL fix86 for awhile now, It basically makes your stock radio adjustable and tunable like aftermarket radio
How is it working for you man? I got a 16 Denali with bose and i put in an lc2i and anything lower than 42 hz is non existent man im soo bummed out
@@rodolfosotelo5929 It depends on your source signal, the JL does a good job at creating 20-20khz but if your signal isn’t as full it won’t be as good. Love the fix86 though, this is my second truck I’ve installed one in.
@@Silentroller93 thank you very much I appreciate it man im going to look into this a little bit deeper those GM intelilink stock stereos are nice and all but the sound quality is not what i expected man i may just end up pulling my sub and amp out if i cant get this thing right i got a wolfram audio AW-1500 and a 15 inch wolfram audio AG 15 wired down to 1 ohm in a 4 cu. Ft. Tuned at 32 the set up sounds nice in my other vehicle but in the Denali the bandwidth is from the 40hz to 60hz big time bummer
DSP is a powerful beggar.
woooow dood
For the budget build its possible to use an aftermarket radio DSPs like the pioneer in this video but you'd have to run in network mode and only run a front stage. So you'll have full control over the front tweeters, front mids speakers and sub individually for time alignment. crossovers for each pair. Only real negative is the EQ still will effect everything together and not individually. In a single cab or extended cab truck it would work out pretty good not perfect but on a budget it'll get it done great.
No they are garbage
@@bennyblanco14 not garbage just not perfect. Most people never even try running the radio in network mode because they don't know anything about it or how works. It'll get the job done for the budget build and people just getting started into DSP. Plus Sony has new head units coming out that will have a real DSP built in. So the stand alone DSPs will eventually be slowly fazed out.
@@bigk7788 I read your comment wrong ..I apologize ...I thought you were referring to those android HU with build in DSP... I currently running a atoto s8 pro android HU and it came with a built in DSP ...now the DSP is far from good along with the preout voltage is 1.5 volts ... It doesn't have none of the fine tuning like different crossover or q factor .. it's basically like an old school EQ .. my boy has the pioneer HU that has a DSP and for 200 dollars, it's not bad at all.... It's perfect for a beginner... I always tell people , if you want SQ besides installation, tuning is the key and one of your best tools is a DSP so don't cheap out .. eventually you gonna have to get a great one like a helix or a zapco
@@bigk7788 Stand alone DSP will never be phased out. Built in DSPs will never have the adjustment capabilites of the stand alone. Why do I say this? I have the same Stinger head unit as Mark and use an amp with DSP built in. It has WAY more control.
@@chuckw6099 actually stand alone DSPs will be fazed out at some point. Like I mentioned before sony has the new es line with a comprehensive dsp built in. Now its just an early attempt at it and once other companies start to step up and compete with sony that's when all the typical dsp features will show in aftermarket radios. As for people that have to keep the oem radio they'll typically run an audio control amplifier with a built in dsp. Eventually other manufacturers will follow suit and offer amplifiers with built in DSPs. Stand alone DSPs was needed because of the technology that was available at the time but, now with how amplifier and head unit technologies have advanced it's to the point now that a standard double radio can have a full dsp and a fairly powerfully built in 5 channel amplifier. Just look at how small some of those micro amps are getting. Right now yes stand alone DSPs are needed but give it time.
Nice job on explaining Mark. Loving my D-5.1300.
I have never seen a factory radio that has separate outputs for high, mid and low speaker-level output. All the ones i have seen have just one speaker level output for front right, front left, etc.
I swore off DSPs for the longest time until my car audio guy talked me into the Rockford DSR1. I'll never have another car system without a DSP.
Do you have any issues with your DSR1 Bluetooth? Do you feel like the bass is lacking at all? But otherwise I agree it’ll be hard to go without one going forward
@@IAM_HC Most of the time, when I immediately open the app it'll connect and then drop. But once I reconnect, zero issues after that. I haven't experienced any issues with bass that I'd attribute to the DSR1 - it's more with my Kenwood sub. I've got a 500w Kenwood P-XW1221SHP loaded box. I love it, for the most part, but I wasn't paying too much attention when I bought it. Frequency response bottoms out at 30Hz. Running a few test tracks and whatnot, I can tell it starts rolling off around 45Hz. I've found the 60-80hz is the sweet zone and will make my mirrors dance, though.
In the DSR1, I keep the "Punch" setting at 8 dB. I set my high pass for the front at 175Hz with a 48dB slope. Rear is at 200 with a 48 slope. My low pass for the sub is at 120/48. A little bit of messing around in the Basic Tuning EQ and, for my setup, it sounds pretty damn good.
2018 Malibu LT, factory head unit to the DSR1 to a Kenwood XR901-5.
Kenwood XR-1801P for the fronts, KFC-X183C for the rears and the above-mentioned sub.
Very good explanation!!! Couple of issues I'm having though with DSPs and Epicenters/bass processors. I have a Stetson Bluetooth processor that I'm considering installing before my preamps to clean up the sound from the head unit before any further amplification. I'll have 4 channels of selectable A, B and AB outputs (or combined as 2 since 1 output has to be split to connect an amp from one output. Meaning 1&2 would be a left and right if used straight). Using it this way I could tune channel 1 however I like and run it to the preamp let's say on the right input, #2 however would be on the left input both controlled by the preamp fader as a mids and highs preamp. Channels 3 and 4 would go to the inputs of the second preamp for midbass/midrange and bass. I think this would increase my tuning capabilities. I also think DSPs have the same features as Epicenters. Select the frequency in the parametric EQ (sweep), adjust it's Q (wide), boost or cut, adjust gain, etc. with tons of more tuning options. The preamps I use have subsonic filters from 30-300hz.
If you have a dsp do you still need a line booster going to the dsp?
Just received a JL fix86 and can't wait to get up and running. I'm a dsp virgin.
Can you make a video explaining the DQDX!
The cameras been on the whole time, huh?
Questions:
how are you ensuring the output signal from amplifier is the signal, from, that you set at the dsp ? How do you know the gains, and frequency buttons on the amp, are not over riding the dsp, and sending out a freq, signal that I'd not what you set with the dsp ? I'm assuming the reason behind using a rta ? is to check for and adjust the dsp, but not the amp settings? Or both ? is the rta, the factor, for output from amp, frequency check and confirm?
got 2 of them plus amps. Love audiocontrol
Excellent video that explains so dang much! Thanks CAF!
Just got a audison 12.14 dsp, it goes in next week in my edge st, with Hertz mille pro 6.5, components and two low profile subs from Hertz 12"
Pioneer allows you to process the sound digitally internally
I've been in love with Audio Control since the mid-80's. But let's be honest, the software that the controls the DM-810 (which I've owned for the past 5 years) is extremely glitchy. Bad enough that it adds its own learning curve, beyond the normal leaning curve with any DSP. And now that Audio Control has sold itself to another company, I fear the worst. Oh well. Everything changes.
Totally agree. I bought this unit based on the views of this channel. The "devil is in the details". It does not hold memory of your presets for an extended period of time. Switching from head unit to Bluetooth AC-BT24 on the app is a nightmare. The app is user non-friendly as adjusting the different settings takes really long as the app's latency & lag time can take over 30 secs.
Another point with those passive crossovers is the protection it gives you with the tweeter. One main reason why I use them. It takes out the extra work and math to figure out what in line capacitor you need for the tweeters if you are going active (IMO)...
I don't believe in active crossovers for the mids and tweeters. Manufacturers spend a great deal of time matching drivers with passive crossovers. I only use active crossover settings for cutting out low pass.
It can go either way with a passive setup. That depends on user experience and aptitude. A passive setup can take time, to truly understand power levels at different crossover points. I've fried more than a couple sets of tweeters, and mid-bass drivers, learning power level differences from 3k and to 5k and up on the tweets, and around 100hz and up for midbass, and 150hz and up for midrange. There's more power than you think going to a tweeter crossed at 3k, and more power going to a midrange at 150hz. Especially when you have a whole lot of power on tap.
I've learned exactly where my amps and drivers are, and have them set close to their thermal capacity, but behind the line, slightly conservative. Right to the line, but behind it a small bit. An initial tune independently, then again all together to blend it all. Active is the way to go in my opinion, capacitors and passive crossovers is old tech. Send exactly the signal you want, pure, no distortion, no time or phase delay, added inductance or termination points that create resistance.
Sonic purity can't be obtained without one, in my opinion.
Thanks, always wanted a DSP but wasn’t sure if I needed one
You dont
@@abelscaliber7969 why not? u mad?
Another great video! But how do you make sure you get the acoustic signal leveled correctly? Do you use special microphones?
Bro i have a question. With a dsp i noticed that i need to increase the vol on my headunit to level 20 to get a good clean sound. Before the dsp i could hear fairly good music at volume 10.any idea why?
Can you use the DM810 as. preamp/headunit by utilizing the digital input from a DAP and the ACR3 as a master volume control for the whole system?
Great job again. Now I know just enough to get in trouble 😂 na. Learned and learning how to do it correctly and my car sounds good for now. But I got that wish list piling up.👌
So if I understand this correctly, I can use a DSP instead of a crossover as long as I have an individual channel for each speaker?
I love my prv dsp when done right it makes it sound so much better
DSP is a must
How about if you use 2ea. 45-100 watt X 4 channel amps, 1 amp for the tweeters and the other for the mids and separate amps for the subs? Could you than not run any passive crossovers, maybe just some bass blockers for the tweeters.
Been watching dm810 videos for the last two weeks for hours
Planning a new system?
@@CarAudioFabrication yep. 821le 3 way active. 2way center channel. Rear fill coax. All cdt. Have a 6ch, 4ch and mono to run. I've watched your jeep build with similar amplifier channels at least 20x 😆
Nice! That will be a fun project
@@CarAudioFabrication yes it will just takes time!
@@SaltwaterBoogeyman Tbh... there are much better DSPs out there. Take a look at Helix or Mosconi. AC only has graphic EQ, while both Helix and Mosconi (and almost every other DSP on the market as well) have parametric EQ with up to 31 bands of parametric EQ for each driver.
In addition you get the possibility to truly alter the incoming signal with an input EQ, which AC DSPs don't have.
If you got a stock system with allpass filters other DSPs are even better than the AC DSPs as both Helix and Mosconi (and i think JL and Audison DSPs, too) can undo factory allpass filters if you're forced to using high-level in to your DSP.
You wrote you got a center... both Helix and Mosconi have upmixer capabilities for proper center and rearfill (differential rearfill), which AC DM-608 or DM810 dont have.
And (!) at least over here in Germany both Helix and Mosconi are in the same ballpark pricewise than Audiocontrol.
Do you check for distortion on the amp before hooking the dsp to the amp
I’m adding subwoofers in an amp to factory head unit
I would not use a DSP
Correct ?
I have this one with the knobs on top. audiocontrol dqdx 6 channel digital signal processor dsp this it
Do you need to add a dsp when you are only adding a subwoofer?
Great video...question...when using a DSR1 and you want to set gains...what do you set the volume and trim levels at to check for head unit clipping? Dsr1 clipping? Amp clipping? I am using a dd1
So the DSP its a all in one processor ,instead of buying active 3 way crossover + 7band EQ. With the DSP you can cantrol via a computer?
Some of the pioneer had units are good I've had one that had 3 high med and low and then I just use 3 amps and never had a problem.
Please do a video explaining the audio control DQDX.
Im looking at these now.
Cant afford audio control.
Im leaning towards the prv
I'll be getting the audison 12.14 dsp amp
Mr mark regarding the misconception no 5 , it’s like 100 percent true, but do you have any video like how can we tune the levels of equilizer and delay of sounds, because even as a car customer thought that the dsp is not required for mid or basic level speakers and thought that the dsp just auto tunes itself to some extent , can you share like any video on how to tune the dsp step by step
How much improvement would a dsp make to the stock stereo and speakers for now? I've got a alpine type r sub with a pioneer amp for bass and plan to upgrade my speakers later. I can't change the headunit on my 2015 golf
I did nothing wrong! I did everything correct!
Goldhorn DSP is the great solution for you system
Wish you had the option to split the pairs into individual channels.
I want one but don’t know who can do the tuning
Great explanation!
How does a dsp work if ur speakers use the last thing in line as what it sees and most amps have built in x overs
Can someone tell me some information/specs in layman's terms on a US Amp 4300x. It's also connected to a "bridgeable" (connected?) 1000 watt amp with a capacitor and a 6 channel line output converter.
Thanks
Nice video..
I have dsp 4.8
4 channel built in amplifier 4 channel not built in.
Now.i want to add 2 power amplifier.
1 power amplifier for front channel
And 1 power to rear channel.
I connect.only rear speaker that sound.
How wiring it.please help me
Can u pair a lc7 with the dsp running in the same music system along with two amps?
You're showing pretty much generic eq, does those dsp can add filters with more advenced options and 1hz precision?
How do you time align subwoofers?
You measure how far it is from your listening position in either Inches or meters
Then let’s say it’s 56in, you input that value in the dsp
If you have multiple subs then just use the average distance
It honestly doesn’t make that much of a difference
@@abelscaliber7969 I have a halo9 and I’m using it for time alignment the speakers are aligned correctly but the subs setting does not go high enough. It only goes to 24.1 inches.
If I set the right subwoofer at 24.1 inches it doesn’t allow me to add a value for the Left sub. Like you said I don’t think it makes much of a difference so I left it off are the subs being that it’s low frequencies and they are not as directional has a speaker
You don't just time align subs, you align ALL speakers so the sound from each speaker arrives at your ears at the same time. In most vehicles, the sub is furthest away, so what happens (without any DSP) is sound from closer speakers (like front doors) arrives first, and then a few milliseconds later the lows from the sub arrive, resulting in sloppy midbass. To fix it you apply delay to the front speakers, so they "wait" on the lows to travel a bit, and then play, so their sound arrives at your ears at the same time as the lows, which results in a tighter overall sound, especially around the crossover point.
@@PURESOUND4 I’ve already align the speakers I left the subs Alone.
could I run my Epicenter into my DSP ?
If you geting new gen android unit some of them 300£+ and git optical in and DSP built in and they sound incredible ❤️
I had have one but installers say there no good and act like they dont know how to install.
Hello Have a good day.. just want to ask if i can also use this one for home set-up. Thank you..
QUESTION: Can I connect two DSP RCA outputs together so that they form as a single input to an amplifier that get those two signals Mixed as one?
(I have a use-case need for that)
I mean will it work or destroy something or will it handle the sum of those signals..
can you help me choose a dsp?
Hey, I'm lil confuse between Alpine Power pack I jut dont want to run an amplifier. My headunit is factory stock. Need Help
I’ve an ap8.9 bit 8 channel ppwered dsp. Like it s lot… my first dsp was a pioneer deq externa dsp in 1996…
Quick question. Does the green lights on the DM608 each channel suppose to be on while the sound system is running. Only light that is on is the red power light
Great info again.! Thanks.
Should you put the DSP between player and amplifier or between amplifier and speakers?
It has to go between the source unit and amplifiers. They take the input signal from the headunit, then send the corrected signal out to the amplifiers.
have a question hope you can answer, is the PRV Audio 8 Channel Digital Signal Processor a good brand or should i still go with the fosgate dsr1? the dsr1 seems hard to find thanks if you can help. awesome vids by the way i learn so much on your channel
Man, they don't give those dm-810's away 😳
Hello I have a question. If my factory stereo has 4 channels only can I split channels so I can add subs? So I still would have the 4 door speakers and 2 subwoofers. Thank you for your help
Question. I have stock head unit & stock speakers with under seat sub on my pick up truck. Can I still use this dsp to improve sound quality?
Will a dsp help a full bridge taramps smart 5k amp get lower on frequencies ?
Will a dsp make coaxial speakers sound better?
Hi Is it a good think using a dsp whit a pionner 80 prs
Is there a way to run active up front and rear, maybe all in one?
Yeah I have a 5ch amp and it would be nice to have 7 channels to connect the component tweeters independantly.
So that’s not how it works, ( at least I don’t think so)
You could tune them if they are on their own channel
Or if they are on a crossover with a midrange woofer on the same channel then you could only change frequency responses .
@@abelscaliber7969 I think that's what he meant.
He has 5 channels, front right and left, back right and left, and sub. He probably has a crossover for his woofer and tweeter up front installed rn.
He was saying it would be nice to have a 7 channel amp so he could have, front left woofer, front left tweeter, front right woofer front right tweeter, back left and right, and sub all under individual control
How can i conect 2 amp of 4 chanel each and 1 amp for the subwoofers??
you mentioned using this with a stock head unit???
how to i tap in before the amp or after? If before the amp does that mean i need a new amplifier? can anyone explain how this works with that stock head unit
Need help. Using an audiocontrol DM-810 with 2 Alpine PDX4.150? I need to know how to set the filters, crossover, gain and input channels on the amplifiers. Thank you.
If I get the DSP Audiocontrol amp for speakers, can my mono subwoofer amp be the non-DSP version?
I have oem amplifier which is can not be removed because amp software connected to vehicle computer. I want to add dsp and change oem speakers plus add subwoofer. Can you add DSP amplifier connected to OEM amplifier speakers outputs? Is this will be safe especially if oem speakers are 8ohms and dsp output and upgraded speakers will be 4ohms?
Thank you brother! Always informative and well communicated. 💯 Thank you! 🙏
How can I run an epicenter with the dm 810
If you have a DSP and your amps are not easily accessible, is it ok to crank amps gain to the max, switch all the amps filters off and work out the tuning with the DSP processor?
Set it all correctly when you tune the DSP., spend the hours and set the gains correctly on the initial setup.
Hey Mark, I have a 2020 Supra with those factory “subs”.
I’ve added a Kicker TRTP 12” sub and AudioControls amp.
Can I use a DSP inline to turn down the bass and distortion on the OEM subs?
The wiring harness I have installed allows me to unplug the OEM subs post OEM amp.
There’s not much space in this vehicle (don’t have to tell you lol), what’s a small DSP I could use? Preferably Audio Controls 👍🏻TIA
What is I got Hu with optical out and connect it with a DSP trough this Optical out (lets say SPDIF), can I control the volume of the DSP trough the headunit or do I need a separate controller to the dsp?
Please, what is your pro opinion of PUZU PZ-X6800S 10CH Car DSP Amplifier?
I am thinking of buying it to support my 2009 BMW X5 E70 series' S676 HiFi Sound System.
Thank you.

Can I use my clarion eq before a dsp? Or that be useless
Depends. If you set the clarion to Zero for all adjustments before you do the calibration using your DSP, and if your adjustments for the DSP are focused entirely on correcting speaker response to create a flat output profile, then the clarion be adjusted to taste for bass/treble as suited for the music at hand.
I just attempted to add 2 amplifiers a crossover and a LC7i with a PAC T harness to my 2018 lexus rx350 fsport and was just a disappointing 3day project that failed and don't understand why, can someone please help me troubleshoot, I did everything as directed twice n still didn't work.
can you use a DSP and equalizer together or is it even a good idea to do so?
A DSP has an equalizer. But for every channel independently 👍
Many mid level head unit, following what has happened with many China's android head unit, now are starting to have 5 or 7 RCA out with high, low, band pass filters, 21+ bands (sometimes even full parametric) equalizer per each channel and delay per each channel... All this while retaining a global system equalizer for rapid on the go changes.
Heck, I've tried a nice Chinese one that had 7 channels, all the filter delay and equalizer per channel and the eqqualizer coulb be chosen between "normal" and linear phase mode. It benched great, sadly only 2V output and only a -70 dB noise floor even while reproducing directly from file.
But I'm sure Dsp will soon be dead, cpu are so powerful that specialized audio dsp chip are no longer needed, just need software (amply available) and GOOD FREAKING ANALOGUE INTERFACES. Lol
Will a dsp make the music from my phone sound better?
I have a question as I am looking for information regarding the standalone AudioControl DM-608 DSP + an external 6-channel amp vs. the AudioControl D-6.1200 DSP integrated amp.
I need a 6-channel amp for mids/highs and a 1-channel amp for subs.
Please note: I have one chance to get this installation right!
Audio quality and fidelity is my focus, but like most others, I want to end up with a system that can get very loud, hit very hard and deep, but stay as clean as possible.
Audio signal source will be 'speaker level', from my stock Mercedes console.
*It's a new vehicle and do not want to throw out integrated system and screen.
Budget is NOT unlimited, so please keep that in mind with any advice.
*I am sure there are 'better' choices on amps and speakers than what I have listed.
I am open to suggestions, within reason.
So...
Which option should I buy and why??
Option 1:
AudioControl DM-608 + JL Audio XD600/6v2 + Rockford Fosgate T1000-1bdCP
or Option 2:
AudioControl D-6.1200 + Rockford Fosgate T1000-1bdCP
Option 3:
???
Am losing anything with the integrated DSP vs. stand-alone DSP or visa versa??
Price is nearly identical between the two options.
The JL amp is a bit low on RMS power for speaker choice. 6 x 75W RMS @ 4ohms.
The AudioControl amp is a bit high power RMS. 6 x 125W RMS @ 4ohms.
Rockford Fosgate T1000-1bdCP - 1,000 watts RMS x 1 at 2 ohms
*Current component speakers are 3.5-ohms, handling 100 watts RMS (400 watts peak)
My current speakers:
3 pairs of Infinity Kappa Perfect 600 6.5" component speakers
2 Rockford Fosgate Power T1D210 Subs
(I may run 2 - Power T1D212 rather than 10s, but undecided. Space available is allocated location for proper size cabinet may be an issue)
This is being installed in a 4x4 customer built Sprinter Van used for various short and long term adventures.
I have space to make a few adjustments if needed, but it is not unlimited due to the appliances required for #VanLife living.
For those interested in additional details that should help audio performance inside and out of the van:
The component speakers will be installed in front (doors/dash), mid and rear zones of the van.
Subs will be installed in customer ported cabinets.
Subs will either be side or down down firing, just behind midline of van.
Rockford subs set to 1-Ohm each, run in series, Rockford amp will see 2-ohm load.
The van is fully lined with dynomat and densely insulated with Havelock wool and 3M Thinsulate.
Thank You!!!
Limited by channels?? Just put 2 DSPs in the system xD. Passive crossovers do make things more manageable but active is just so arousing. I finally went full DA. Ipad usb into iFi coax into C2O toslink into DSP then finally CAT5e into amp. It was a pain but so worth it
Amplifer channels are usually more the limit
Helix dsp have input rta and eq
Hi can dsp tuning makes bad Android Auto sounds good?
