Hey there, I want build a device to switch between active loudspeakers which use balanced connectors. I have 4 (or more) different active loudspeakers (stereo) and I want to switch between these without a pop noise (and without removing the cables).
I simply have one DAC and I will use its stereo output, to the input of the switcher and I am going to need 4 (or more) balanced outputs to switch between while listening.
I would like to hear your comments about how I can build it. I I appreciate your help, thanks in advance...

switch will likely cause pop no matter what
why not to have splitter to drive 4 active speakers all at once, with volume pot on each output, sort of like mix board, but four outputs

Removing pops I think means either using a slow switching device such as JFET with voltage ramp on the gate, or else find a zero-crossing audio switch chip or attenuator chip -
this will require a microcontroller to drive it though.
A fader for each output is another approach, as mentioned above - its the most flexible but more cumbersome if you only ever want to switch.
