Just select 2 channel or 4 channel in the Jukebox settings...
Ok, I have always kept mine set on two channels. Are the 2 channels, headphone and line 1 out? If so, what are the 4 channels, I only count three....headphone, line 1, and line2....where is the 4th line (or channel) out?
USB perhaps?
L8.
The headphone out is controlled by the volume control.
The 2x line-outs are the 4x channels, or 2x analog stereo (left channel/right channel) line-outs.
I use my 1st line-out to run into the front of my stereo for immediate listening after a show, before I transfer.
