Hi,

Is this capable of separately controlling the volume of the left channel from the right channel? Or can the volume be bypassed? I need to separately control the left channel volume from the right channel.

Regards

You want to channel the output channel ??

It does.
Change the output as follows: R- L or L-R, (no need to invert DAC conductor)

thank and see
