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.

WARNING

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
