minimize interference from magnetic, hum, and
RF sources.
Since a phono cartridge is actually a true
balanced source, a balanced input is provided.
Connect the output cables from your turntable
to the left and right channel XLR input. Do not
short pin 1 (chassis/ground) to either pin 2 or 3 of
the XLR connector at any point in the cable,
turntable chassis, or tonearm. This will cause
hum in the system. Pins 2 and 3 must only be
connected directly to the cartridge pins. If your
turntable does not have XLR connections, use
the Cinch (RCA) input instead.
