The switch we could not figure out, is a small high pass for the Satellites. When set to normal the high pass is on, set to full, it is off. So it is a good way to protect smaller drivers. Thanks to Jonathan Augle for the tip. You can find out more about the amp here: amzn.to/2M2i65T
We have tested this 2.1 bluetooth amplifier board, 2.0 channel mode: it is recommended to use a max power of DC21V and a full range speaker of 50W*2 4Ω for the best working condition. 2.1 channel mode: it is recommended to use a max power of DC24V, a L/R speaker of 50W 4Ω and a subwoofer speaker of 100w 8Ω for the best working condition. Hope it can help.
Parts express seel a diy speaker kit with this Amp and they use 40w8oms driver ( dayton cx120-8)and tangbandw5 4oms subwoofer with a passive radiator 8" Can you explain me please? I' building the 200w diy kit and i Wonder ....
I have this board. It's really nice board, better than previous TPA3116D2 2.1 I had, except it's Bluetooth. Don't expect much from Bluetooth. It's using a JL Bluetooth chip with some random number on it (you can't look up any spec) which has only basic SBC codec.
Hi, I guess you forgot to flick the switch on this amp. That switch between the second and the third knob. That thing wither allow fot the satelited to go full range or to cut the frequency. i'm not sure at what point it crosses though. Really good review using the mic to see the graph. Way to go man.
I don’t really understand, it does Not change the Crossover when I put it into „Normal“ Mode. The other is „Full Frequncy“ and it is Full Frequency the entire Time.
Do you still have this board? I ordered one with Bluetooth and the other without. Power with 24v 5a power supply and only a left and right channel, no sub yet. It had a terrible hiss and pop every time I touched the treble freq or treble volume knobs, the two next to the main volume knob. I returned them both. I really want a 2.1 board without bt because I will pair a Arylic board to bring by and wifi in, and a input selector switch I'll build. I've been looking all over for other versions of this board without problems but it's hard to find. A few fixes out there involved resoldering to the board and that's more than I want to do for fear of ruining it. Oh and that little switch is the filter that cuts off low freq to the satellite speakers.
I think You need to do a second review on this board, I bought it after Your video but there is issues with it. At low volume in bluetooth the board goes to sleep every 30 seconds to a minute and wakes up after half to two seconds again... There is a great deal of noise due to the cheap pots (B50K) on it and apparently that's why it goes to sleep (in low volume), they cured the static noise problem in idle by sending it to sleep mode as soon the media stop playing. How ever, the board can't sence the difference from low volume and no volume... Changing the pots to 10K (B10K) solves the horrible noise problem and I can't understand why the chinese didn't solder those on in the first place... I myself returning this board since I can't always crank the volume up to make it work properly.
So this is a 200w amp, so you need a power supply that produces at least 200 watts to get full amplifier power rating. Would a power supply that is 24v 9a making 216 watts have the exact same effect as a power supply of 12v 18a making 216 watts?
No, you need higher voltage to get higher wattage in the case of amplifiers. Components are usually limited by amperage, so using the highest recommend voltage will usually get you the highest output wattage.
Honestly I did not realize they carried a board similar to this. I have been to interested in looking at this one that I did not notice bit.ly/2SefvZ7 HAving said that, they look exactly the same. But since I havent' tested the one at PE, I can't say for sure if they perform the same.
Why does no one ever preview what the noise floor is, or what the start up or various Bluetooth tones are? You mentioned a voice when switching to aux in, would this amp be acceptable in a product that will be sold?
Now that you mention it, I probably should have put the voice on there. It just beeps when you switch to BT and says line in really fast when you switch back. I don't see why you couldn't use this in a build you sell. Just keep in mind, that it will be an Asian woman's voice. So if that turns you off, then you shouldn't use it. But it is nowhere near as bad as some of the Asian amplifiers I have used. Which I would not recommend if you were going to sell it.
@@Toid And what about the noise floor trough aux? anything noticeable? i could test it via bluetooth and its pretty damn quiet, but i didnt have a aux cable neither the adapter to use my phone jack
What I don't like is that when I start the music, the volume starts low to higher the first four seconds. Not nice when you watch a movie, because it shuts immediately when their's no sound
24V power supply will deliver double the watts at the same amperage. 12V * 5 amps = 60 watts of power to the speakers 24V * 5 amps = 120 watts of power to the speakers An amp rated 12V-24V would best be served by a 24V * 10amp power supply (if it can take 10 amps).
@@TheActionBasstaard probably not. I did just figure out that button does add a high pass to the satellites. It's not much about 5 decibels, but that would help protect the speakers.
thanks alot! it helps! I thought it could be more clear to clarify control function, when you show curves it is better to mark the min/max curve of each knobs. BTW the sw would be crossover on/off. I think the designer is Chinese so he name Subwoofer as base and sat L/R as treble, A bit odd is he removed L/R highpass yet add its lowpass -= treble freq. Do you have a video on the OminiMIc? would you please add link here?
Hello! Just seen your review and its pretty good. Just one question, there is no high pass on satellite speakers? I was planning to buy but if there is not high pass I wouldnt, dont want to blow satellites with bass, Thanks in advance, I would be very glad if you could answer 😃
Hi there. I just purchased the upgraded Bluetooth 5.0 version of this amplifier. I purchased a 6s battery protection/charging board and a 24v 10 amp power supply. The battery board has no plugs, just 2 pads. Should I run 2 sets of wires off the battery board, one set going to a dc charging port for the power supply and the other set going to the dc in on the amplifier board? Also could you give me a little more info on how to maybe integrate the ac power supply board you have linked here and how I can use that together with a rechargeable battery pack ?
Hi, Can I bridge the output from the left and right channels too to get mono? I only have space for one widerange speaker. And is bridging just wiring the outputs in parallel or something else?
Bridging is wiring the positive of one channel to the negative of the other. I have a generic amp board like that, not as nice as that one but has the same tpa3116d2 chip. Its bridged at 8 ohms with a vintage quam 3in speaker and it works fine.
Hi i have this amplifier and have given 12v power supply to it. Subwoofer makes popping sound. It doesnot pop at very low volume. Is it because of less power supply volts? Tried tangband w5 and peerless 6inch woofer(model i dont know). Using 20volt-24volt will solve this problem?
I'm going between this amp and another amp for a 2.1 build. Once I test the other amp I'll know for sure. But I'll definitely post the build video either way
HI. I have purchase one same amplifire but it has a noise.When i put the power in,my speakers going to explose,that is for 1-2 seconds after that it works correctly. I think its normal to hear a litle pop but this is too much,it is like current link in to my speakers. Do you know why is that?
Yes it does. The low-pass is between 80 to 160 Hertz. Meaning it's going to slowly tail off everything above 80-160 Hertz depending on where you set your knob
there is no hi res bluetooth products on the market that i know of. bluetooth was not built for music so it cant handle as much data that you need for high res
@@niumy1972 now i know why i cant connect to the bluetooth i solve it lol because this bord is not does not have a bluetooth lol i did check the info online i just order it lol 😂
Lol i am currently using that amp to power 2 12 inch 250w rms each subwoofers. No wonder it can't even move them i am powering it with around 15v and my subwoofers are 8 ohms each so it is running 4 ohms total at 15v lol. I really need to get a new amp.
It runs an 8" dayton sub i have much better than i had ever thought it could. that and a pair of custom built Tapered Quarter Wave speakers with just a pair of Dayton RS100 full range drivers.
I'll test that. It didn't seem to have any effect when both the sub and speakers were hooked up together. I'll unhook the sub, test it and get back to you.
@@Toid it would probably be easier to see with a sub on the satellites since you probably won't see a difference on little full ranges but it would help with distortion
It does appear to be a high pass. Good call. It is not much of one though. Starts about 200hz and drops it about 5db by 70hz. Enough to protect some smaller drivers
Good enough for me 12v 6amp? power supply. I drive Marshall stanmore speaker with this amp 40w woofer and i put logitech 40w 4ohm woofer on parallel. Woofer side works pretty well now, though still i'm able to blow them up if volume is cranked way up. Still need to add mid speaker and maybe look into limiting treble in favor of mid speaker.
Is it possible to read the frequency graph like 6:35 using the lower cost calibrated mic like imm6 (or any other regular mic we might already have ) Or maybe by using the Kicker speaker to line in level convertor explained in ruclips.net/video/7orJovlXvBM/видео.html ?

Hi 123 toid .. does this suffer from bluetooth noise that most of the boards seem to have.

What I don't like is that when I start the music, the volume starts low to higher the first four seconds. Not nice when you watch a movie, because it shuts immediately when their's no sound
