Quantum Broadcast Board. (PICTURES)
« on: December 25, 2004, 12:25:38 AM »
I ran across this Quantum audio labs broadcast board at work the other day. it looked cool so I bought it. It has 12 channels. 14 inputs.

Its a little beat up but the faders look to be in good condition.

It has reichenbach input transformers and NE5532's. It has a three band EQ where each band has push button selectable frequencys. There are WIMA caps in the EQ section.

I believe they were made here in LA.

So anyone have any info or schematics? its a Series 22 board.

Thanks and Merry Christmas......

Oh yea, I re-read your email. they sound very similar. Theres about 17 electrolytics on the channel board and I'm wondering how many are in the signal path. I'm also short the Power supply. I'm guessing +18/-18.

You can select between two sets of input with a button. There is a button for Pan. I'm thinking you can toggle between mono and stereo for each channel.

there are two main outs. Audition and Program. You can assign each channel to left or right of each of these outs. I want to use one to sub mix some how....

I'll post pics soon.

A simple Google Search turns up contact information for two of the designers.
