It is the MITSUBISHI QUAD EIGHT 4-BAND EQ 82041 and Trident TSM EQ CB9132.
Does anyone who has used ICs for Trident CB9132 EQ?

I have the schematics for the CB9132, found them while looking for the line/mic module of the same console. PM me if you're still interested. I am still looking for the 82041 schematics though, any luck with these so far?

Hey, I just bought a pair of those eq's too. I googled around and found this...

We maintain a console master book from a Mitsubishi Filmstar console that has docs on the 3-Band Semi-Parametric eq. The pinout should be the same for all similar Mitsubishi era eqs, but without additional information I recommend checking everything twice......err,... or maybe three times.

Pin# / Signal
8b / -18vdc
9b / +18vdc
10b / Audio Common
11a/b / eq out
13a/b / eq in -
15a/b / eq in+

Probe the connector, check the pcb for correct components at each pin and be very careful before connecting power.

I haven't tried hooking mine up yet...did you ever get a hold of the actual schematics for the 82041?

*BUMP*

Anyone found schematics/pinouts yet?

@Analog Al: Did you try the pinout of your post above? did it work?

[Analog Al]

Yes, it did work! Those are the correct pinouts.

OK, thanks! Great timing, i'm about to finish my little DIY rack of console channel strips & modules this weekend and the quad eight EQs are part of it.
