4 channel system, 1 volume control

Using 2 amps to build a 4 channel system, ie two amps paired together, can I use 1 volume control to control all 4 channels at once? Eg making a 4 channel active speaker system… 2 amps gets me 4 channels with DSP and amplification. Can I rig 1 volume control to control the volume on both at the same time?


4 channel potentiometers are available so yes you can. Do you need a diagram?
