INPUT CONNECTIONS

The MX110 provides six separate pro-
gram inputs controlled by the INPUT SELEC-
TOR switch. One input for tape monitor or
If a cartridge requires less than 47,000
ohms load impedance, a resistor can be
added across the terminals of the cartridge

CONNECTION
TAPE MONITOR Tape input operates with tape machines containing their own
playback preamplifier.
The auxiliary input accepts any auxiliary service requiring flat
