I finnished some time ago controll room module
for mastering console, uP-controlled, passive,balanced,
with stand-alone controller...
total is about 90 Teledyne 712 relays...see lo-res pic:

Functions are:
4 monitors each with offset
12 inputs each with offset
Digitally controlled balanced relay attenuator 0...-127.5 db
step 0.5 db absolutely clickless
4 inserts
5 points to listen inserts
dim (user-defined)
talkback, user-defined latch time and dim level
mono-sum
mono-diff
mono-l
mono-r
swap l-r
4 presets for storing snapshots
The main thing it came up very versatile in controll
and absolutely clean in audio...
At this time, I working on controll room module
for medium-budget studios.
Please your input: what is necessary, what is not?
I think 4 inputs enough, maybe 5th for situation
if we need to play say cd+keyboards...
Selector which goes to record independantly
from monitor can be wery helpfull too...
3 monitors...talkback, dim, offsets on inputs/monitors...
mono-l, mono-r,mono l-r...minimum electronics, all passive...
but option for balanced buffer should be there...
seems 0.5 db steps is overkill, 1 db is pretty good enough...
Look on this pcb, it is audio board for one channel,
pl/xlr inputs and reletively cheap Aromat etc relays:

Ideas???
People interested in kits? PCB's?
