Before making or altering any of the connections described below,
be sure to turn off the power of the MX-50.

output jacks of your control amplifier to the corresponding INPUT jacks
on the rear panel of this unit. Always check that
a) the RCA plugs of the connecting cord are clean,
b) the left and right channels of both units correspond,
c) connections are secure, and
d) both units are properly grounded.
if possible, use only speakers indicated on the rear panel next to the
SPEAKERS terminals and with adequate power handling capacity.
Driving speakers with extremely low impedance (or two 4 ohm pairs)
at full power may cause the protection circuit to activate.
When connecting the speaker cords, observe the “+” and “—”
markings on the backs of the speakers and MX-50. If the “+” and
“_” polarities are reversed, the sound will be unnatural and lack
bass.
