- Replacing a failed chip on the phono channel. The signal was only coming through on the left side with a loud ringing sound.
I never understood the appeal of rotary DJ mixers until now, but this thing really is nice to use and it sounds great. The master EQ is a lovely touch too.
Well made and a clean layout.
Lethal... back to the future 😅 no bother to you buddy. Genuinely talented.
Cheers bro!
Great work and nicely presented dude !
Gracias mi amigo!
I’ve had problems with channels not sending to the PFL or entire channels (both phono and line) only sending left or only right… how would I go about repairing that?
The folks over at Omnitronic support are *REALLY* helpful and cool. Open a support ticket with them and see what comes of it. You can always keep working on the mixer while you wait for a reply. I'm sure they have encountered this problem before and know EXACTLY which part fails and needs replaced. That's how I was able to fix this so easily. They told me which part to buy and gave me diagrams of the PCB. Let me know how you fare! GOOD LUCK!
Recon this mixer could be taken up a few notches with any upgrades etc? I've got one and think it's great but surprised no one has had a tinker around with the internals.
For sure. You could add anything to it. since there's loads of space inside it for PCBs and on the front panel.
A Master reverb module would be pretty useful with a HPF after it. Maybe a VCA with a sidechain. The possibillities are endless really...
The Baxandall EQ's on each channel sound really beautiful so I wouldn't touch those or the "Blue Velvet" Alps Pots.
@@Nordl3 Iv'e heard the term ' Baxandall EQ' before but never dug further, didn't realise the EQs on this mixer were particularly special
Interesting suggestions, I was thinking more in terms of 'audiophile' type upgrades. Swapping op amps etc. Or do you think thats all a bit pointless.
I had a Master Sounds for a while but honestly couldn't hear much difference and thought the TRM was such good value for what it is I ended up keeping it.
@@s_9878 You could always try a different opamp on each of the 4 phono channels and decide which you prefer but I wouldn't bother. I'm not an audiophile - if it ain't broke don't fix it I reckon.. The NJM4580M is well suited, sounds great and it's an oddball footprint (DMP8), although it looks fairly close to SOIC8... I was tempted to try a different opamp but since this was a repair for a customer, I just bought the correct part.
The TRM-402 is a really good price for what you get. You couldn't come close to that price if you were designing and building only one or two DIY units, when all is said and done. The Alps Blue Velvet pots are ~£15 each!! There's 7 of them in each unit!
