DI503J Triple DI and Re-Amp / DI503J triple DI output buffer

« Last post by TheWoodman on February 04, 2026, 06:30:55 PM »

Is the output TS jack of the Triple DI buffered (when not in reamp mode, so just paralleling the input signal).

MC624 Monitor Controller / Re: 12 year old manual recommendations outdated

Hi,
We use this one.
We couldn't find a TV model that worked 100% so we programmed the MC624 manually for this remote.

Check that the input potentiometer is working by measuring the resistance between pins 7 & 10 of the input transformer. The value should vary from 0 to 200 ohms when rotating the input potentiometer.

JPK, 
as per a previous communication almost a year ago, you said you were going to update the section that spoke to the unit being controlled by TV remote and update suggestions, as to specific unit(s) that would work, I never got that info back from you. 
I've already gone thru a programmable remote that didn't work well, and I would like this advertised function to use.
Thanks, 
StG

Ok I hit all of those pads again, but still the same issue. The good news is now the issue is consistent and not intermittent anymore. but I should mention this happened before I re-soldered the pads. The issue is also on my right unit, so when I link both of my units together, it will pull the heavy compression on the left unit as well.

It looks like a sidechain gain issue.
Check the solder joints of R22, R23, R28, D4.

Yes it does. It’s still responding to signal, but it’s almost as if something is driving the input way up

When this happens, does the needle return to 0 if you remove the signal completely?

So in that photo I have a vocal running through and if you look at the knobs, all of them are down. But the signal is still getting slammed. I can faintly hear the source even with the output down. The signal is distorted as well. But again, this is not a constant issue. Sometimes it slams the signal, and sometimes it operates normally.

I am not sure I understand well.
Do you have a sudden excess of input gain? Does it looks like a bad contact? How does it ends? Please explain more.
