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

Click to expand...

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

very interesting project, is it possible to have a direct I2S-LVDS input with HDMI connector (PS audio standard) in the rear panel and possible to select this, besides all other inputs?
I dont understand why you choose Amanero USB card when there are latest products as Xmos Xcore200 chipset based cards and dsd 1024 support in native mode?
Thank you so much and soyy for my bad english.
