Post MITSUBISHI QUAD EIGHT 4-BAND EQ 82041 and Trident TSM EQs CB9132

I bought some EQs low. Now I am looking for the schematics.
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?

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.

Waking this thread up for future resource.

I bought four 82041 Westar EQ modules on eBay and racked them up successfully. The pinout above is correct. I have crude (photographed) schematics for these modules if anyone is on the hunt. The ebay seller will likely include them with the purchase - that's where I got them.

The only thing I added was a circuit to change the output from unbalanced to balanced using a THAT1646 IC. See the schematic attached. Also I found connectors that fit the modules headers. Also attached is my routing for the circuit, not very pretty, but works fine. I put a 47uF between the output of the card and the THAT1646 circuit to filter out potential DC. Also those two 10uF caps are Non-polarized.

Here's a link to buy them: 09222326825 HARTING | Mouser (I bent the pins over to make it 'right-angle mounted', which I couldn't find anywhere.

I found small 1" proto pcb's that fit the cards edge and have a span of 9 through-holes which is enough pins to catch the span of the pinout on the module (8-15): ProtoBoard - Square 1" Double Sided - PRT-08814 - Karlsson Robotics

Got my 2U case here: New 2U Rackmount Enclosure 37-2U - Electronic Enclosures | Circuit Specialists (And drilled the holes by hand. And cut rectangle holes for the modules in the front panel with a jigsaw.

I have one channel burning in right now. Seems good so far...
