I am building an active monitor controller equipped with a few bells and whistles like minor DAW control and volume metering and display.
The layout so far is 2 in and 3 out.
So you can select from two sources and send to three sets of monitors.
I'm using JLM Dingos to unbalance and then balance each L and R.
The unbalanced L and R are then brought via relays to either an 10k encoder using pga2311 for volume control (and display) and/or a stepped attenuater.
After leaving the volume control the L and R enter a switchboard.
The switches provide mute left, mute right, reverse, dim and stereo to mono.
It would then eave the switchboard then through three switches back through the JLM Dingos to the desired out.
I used several circuits I found on Elliot Sounds.
Eventually I am going to try to use spst switches or tact so the layout may be different but for the moment I am using dpdt push button switches.
I would love some suggestions on the switchboard.
Attached are the schematic and board.
