Thank yo so much! Brilliant, unicue content, as always. Waiting for part 4, cheers!
A fantastic channel with great content.
the whole myth of discrete circuits in the rotary community is laughable.....total snake oil
@@larrylevan3378 it definitely has gone too far. But I believe that someone very clever can explain some real benefits - there are some applications where going discrete may help. In DJ mixer field from my observation the only benefit from discrete circuitry is having more control on sound coloration, which is just one of the ways of processing the sound. Superiority is not the reason for going discrete. I talked with some mixer manufacturers that went discrete and unfortunately I didn't learn anything interesting. Just marketing talk.
Buenos dias...utiliza el famoso Ne5532 para la etapa de preamp...en equ estaria bien un tl 072 , 4580. O sus versiones quadruples. ...para cascos el 4556 y en la etapa sumadora ne5532 estaria bien, el control de volumen por VCA asi como crossfader con algun SSm de control, buen dia y sigue asi!!!
Most modern cartridges want a unrealistic capacitive load i.e. Audio Technica where the ideal load is somewhere around 100pf... The Technics turntable's cables are aprox 120pf and combine that with most DJ mixers who for no reason seem to have a very high load i.e. Xone-62 where it's 330pf! So that plus the turntable's cables will be 450pf! (not including what ever the leads for the headshell are) And you can hear that peak with those cartridges. With the 1620 it's weird you don't see the input cap but there must be enough parasitic capacitance between the input RCA's and phono card as otherwise without any load if you don't have a input plugged in you would get self oscillation and you don't
@@vinyljunkie07 yes, I think that 1620 phono input impedance simply relies on cable capacitance.
@@mixersinside Also the other funny part is about the FX loop is the output of that and the tape out which is taken from the same thing is the signal is shifted 180 degrees out of phase and then it's flipped back to be correct when it goes back into the mixer. Personally the most annoying thing I found on this mixer was the design of the output stage where the gain was put after the volume pot so there was always constant high amount of hiss on the output even if the output knob is at 0.. Weird design choice in my opinion instead of doing it the other way round and using a buffer so the pot doesn't effect the output load
@@vinyljunkie07 regarding output stage: the other way around would completely ruin the control over the headroom. Imagine having 10x gain stage and 2V input signal. When you will apply circuit described by you, the gain stage amplifies the signal 10 times so you get 20V (it's clipping AF), and then you can attenuate the signal that is already clipped! The original approach makes perfect sense - first you passively set the reasonable volume an then amplify the signal. Gain staging is always bargaining between noise and headroom.
Thank you for taking proper time to address the importance of the input stage + cable capacitance and its impact on the phono stage! Very great series in all other aspects as well :)
I fully understand why you don’t want to be the guy to teach me electronics 😅 But somehow you have become the guy that teaches me electronics 😆 Maybe it is because I’m very interested in mixers, and by using this Urai as a real world example, I’m actually paying attention and really trying to understand what you are explaining, as a former teacher, I know how much genuine interest and excitement for a subject will affect a students ability to soak up the lesson of the day. I learned a lot from this video. Thank you very much for taking your time to record and upload these “lessons” 😊
Thank You to bring us your knowlege and sense about audio
this video series is absolutely amazing 😃
@11:08 oh man, i think the audiophile crowd is going to show up shortly to argue this point until the end of the internet 🤣
@@bikesbeersbeats Hey, can you explain why?
@ because a majority of audiophile purists do not understand much of the technology that goes into the various components of a sound system. Many have no idea that vinyl uses the RIAA approach to solve a bunch of practical issues with vinyl. They are of the believe that vinyl is the ‘purist’ form of audio when its all signal processing at the end of the day. Thanks for these videos, they are great to listen to!
@@bikesbeersbeats it's hard to argue here, I even showed screens from Wikipedia. This is basic knowledge. Thank you for kind words.
Excellent work... 100% Approved by me.....
I really enjoyed this video and your explanations on modules and theory. I look forward to more videos by you on this subject matter and project. BTW, 808 Bass Queen is a classic, I have that on vinyl myself. Great taste!
Informative Video! Thank you!
You should make a mixer .....
@@Astroboytoy please check my channel, i describe the process of making a mixer.
I used muses in my custom mixer build. Also my mixer os super easy to op amp roll
Thank you for providing this video, lots of hard work went into this I can see. This has also helped me in my quest for my next mixer. Cheers!
I've had a Urei 1620 for decades. But this Omnitronic rotary mixer is very good (and cheap).
Interesting video, not being a DJ though I'm really confused, weren't DJ mixers 2 channels with faders, a crossfader etc? What are these pot volume mixers?
@@edsavage6214 there are 2 types of DJ mixers: fader mixers and rotary mixers. Rotary mixers are the most classic ones, this is how it began. Now most of the mainstream mixers are fader type. Rotaries started to be more popular recently. The only difference is that you control the volume with slider or knob, its about the feeling. The principle is the same.
@@mixersinside thanks for the clarification, honestly I had never heard about this.
whats the nice song in the background .. like it alot <3
@@carstenneuhaus6090 Paul Walter - Roots, Rock
The thing with electronics is the components don't matter as much as the design. Whether you use ICS or discreet it doesn't matter what does matters is who designed the circuit.
@@mcsniper77 every component has its limitations so they matter when making a design. With different design goals you will use different components. Thats how I look at it. In the next episode I will try to inspect how much passive components can change performance. If you already have some resources or good examples in this matter i will be thankful for sharing. SBOA312 paper by Texas Instruments perfectly shows how using different type of resistors can affect circuit performance.
Great work brother;) Thanks for your time and dedication to this topic. Very interesting! Can’t wait to see and hear the section on the summing amp. In my opinion the most important part of mixing. When you can’t tell the difference from one track to another it’s like magic!
So nice! Could there be an 'fx insert'? So that if I would want to add lp/hp filters, I can do that through the inserts (per channel?)
@@MaxVersace I hope that thanks to this series it will be easier for you to build your own mixer with all kind of features you want to have. All the features I plan to include in this build were described in the video.
Sell it as a KIT form so we can follow a series to build it ;)
@@aportilla007 it will be not a DIY friendly design. It's too complex to sell it as a kit and i don't want to spend time helping to troubleshoot the mixer build. I know how it ended with simmilar project made not by me. I would prefer my customers to be happy and get something working, not to buy a kit and then not power it up because of lack of skills.
Awesome. I hope you'll share schematics or maybe even pcb files too!
@@fkthewhat service manual of UREI 1620 with schematics can be easily found online. I will not share pcb files and full schematics of my version, at least for now and close future.
What about a cue system, headphone output? Aren't those essential for a DJ mixer? Imo you described the essential parts for a general audio mixer, not a DJ mixer.
@@eeliyx this is Part 2 of the series.
@mixersinside so I assume cue/headphone will be dealt with in a later part? Looking forward!
@@eeliyx Yes. There is nothing interesting to say about it in block diagram stage - it's too obvious. I will comment it when speaking about electronic schematics.
@@mixersinsideMakes sense, thanks for the the response. Doing a parts cost vs sound+measurements analysis in two functionally identical mixers is such a great idea. It's very hard to judge by simply looking at single parts datasheets. Always depends on where and how the parts are used.
Great content. It would be great to have an option for vinyl transfers in which all unnecessary circuits were fully bypassed to get the most transparent signal for audio archival. I love the exclusion of the isolators. That will limit the amount of needless fiddling djs do which in my opinion ruins mixes (think Joe Clausell as one of the worst possible examples of ego over music).
you feel me, cheers
Very didactic. Thanks to spend your time with this project
Man. You are going DEEP. What a fantastic series!
Your channel is excellent. It is so refreshing to see a young person as yourself talking so openly and sharing your knowledge. There has been no precedent for this. I am following your progress with great interest and I see a bright future for you.
Thanks so much for the kind words! This channel is indeed something new in the world of DJ audio. I’ve always felt there wasn’t enough open exchange of ideas in this space.
Thank u @@mixersinside
Great series. Tuned in…
I am so exited about the series!
S alute! Another great video !! Don't count as an off topic please, but since you open the question regarding the RIAA preamps, i was thinking about a practical way (not theory with lot of formulas) to explain / show how the Load capacitance and Load resistance will affect the sound of a phono cartridge (lees / boosted lows/highs). For example, if we take a modern DJ mixer, the RIAA preamp of it will 47kOhm load / input resistance and 330pF capacitance. On the other hand lets take the classic Ortofon Club Mk2 with recommended 47 kOhm and 200 - 600 pF, and "exotic" Audio Technica AT-XP7 with 47 kOhm and 100 - 200 pF. Same load resistance but way to different load capacitance. To my ears Audio Technica sound with less highs i mean by level not by details. Thank you :) !
@@СтефанАтанасов-у5ы there is an excellent article on cartridge loading on Rod Eliott's website (the one I recommended on the previous video).
@@mixersinside I will gonna check now )
The rk40 is not a myth..bozak when they went from allen & Bradley pots to rk40s.. Bozak asked alps for a special make for bozak only them... You could not ask alps back then for that rk40 it was only sold to bozak. Now when bozak were no longer selling mixers in mass.. The deal with alps was gone but the spec is different. So a bozak rk40 is different than a urei rk40.
@@djBroRay there are some myths that Alpha Recording System order some special ALPS pots to get the same curve as RK40 used in UREI. In the next video I will compare the curve of regular modern RK271 and RK40 taken from UREI. Didn't know about the Bozak case, I don't have opportunity to confirm it and I will appreciate any evidence on this.
great info! i prefer filters and effect sends per channel myself
This is very informative and detailed information....even down to comparing the Alps RK40 to the RK27, and also seeing if there are modern alternatives. Thank you very much for sharing your knowledge with the community.
