Could you be using a connection cable that contains a
resistor? Use a connection cable that does not contain a
resistor.

or Output Doesn't Sound Like Stereo
Check the setting of the Assign switch (Right, L+R, or
Left). The DS-50A uses an identical construction for the
left and right monitors, and makes no distinction between
left and right. During digital signal input, set the Assign
switch L or R as appropriate for your setup.
