ZX-7/RX-7 Basic Operation
2-7
1 & 2 UNBALANCED/BALANCED INPUT 1 TO 7
CONNECTORS
Provides audio input for the speakers connected through the
unbalanced (RCA) inputs or balanced (XLR) inputs.
The illustration below shows the appropriate cable pin-out for XLR
connectors.
Caution!
Never make or break connections to the ZX-7/RX-7 unless
the ZX-7/RX-7 and all associated components are
powered off.
Do not connect the outputs of one channel to the outputs
of other channels or to other amplifiers.
3 CHASSIS GROUND
Provides a means of grounding the power amplifier to another
component within your configuration in order to eliminate ground
loop.
4 REMOTE TRIGGER INPUT
Enables the ZX-7/RX-7 to be controlled by the MC-12HD/MC-8 or
other external devices with a 3.3V DC minimum to 24V DC
maximum trigger output. Connect the trigger output of the
external device to the TRIGGER INPUT of the ZX-7/RX-7 amplifier.
The ZX-7/RX-7 will automatically respond when the external device
is powered on and off. When the controlling device is turned on,
the amplifier will turn on after a delay. This delay is intentional and
serves to protect the speakers while the unit stabilizes. During
start-up, you may hear relay clicking. This is normal operation
5 MASTER POWER SWITCH
Connects and disconnects power from the AC Input Connector to
the Amplifier Power Supply. When this switch is on, the front panel
standby/on LED illuminates. When it is off, the front panel
standby/on button will not function. Set this switch to off when
making or breaking connections to the amplifier. The Master Power
Switch also serves as a breaker.
To power on the ZX-7/RX-7, press the rear panel master power
switch. The ZX-7 120V AC includes 2 power switches. You must
power both switches on or off. When powered on, the front panel
LED will light. There will be a delay from the time the power is
turned on until the power is applied to the speakers. This is normal
operation and protects the speakers from potential damage while
the unit stabilizes. You may hear a relay click during start-up, which
is also normal operation.
Your power amplifier is supplied with a heavy-duty magnetic circuit
breaker. With the ZX-7 120V AC unit, there are 2 heavy duty
magnetic circuit breakers. If power to the amplifier is interrupted,
inspect the circuit breaker on the rear of the unit. If the circuit
breaker is in the OFF position you can reset it to the ON position to
