output level is high, set the switch to "+4 dBu, " and when that

CH-2 EFFECT LOOP RETURN jacks
These are input jacks for the return signal from your effects
device. Stereo connections (L/R) are possible. To use the unit in
mono, use the L/MONO jack.
* When using this unit in mono, the return sound will not be
output through the speakers even if you input the return sound
to the RETURN R jack. That is, when the L/MONO jack is not used,
only direct sounds will be output (regardless of the LOOP switch
setting).
* Before you make connections to the RETURN jack(s), be sure to
switch the units off.
