Auxiliary Returns
The MDR16 has two stereo auxiliary returns, which can be accessed via the two pairs of 1/4-inch phone jacks located on
the top panel. The auxiliary returns can be used to connect any stereo line level signal, but they are primarily used to con-
nect the output of external effects processors. The MDR16’s onboard effects are internally connected to the Aux RET2.
