Channel 4 Monitor Input
Channel 4 has been added as an extra channel for monitoring purposes. This signal does not mix with the
Main stereo bus and therefore the Line Out is not affected. This input has it own level control. The left and
right inputs can be used as two separate monitoring sources and the signal goes directly into the amplifiers,
bypassing the master volume.
