ZX-7/RX-7 Basic Operation

POWER CONTROL CONNECTIONS

The ZX-7/RX-7 features a built-in remote power-on system that will

automatically switch the amplifier on when another device in the

system is switched on.

REMOTE TRIGGER POWER ON

How to make connections for remote power-on using

components equipped with a DC trigger jack:

Using an accessory cable with a 1/8” mono mini-plug and the

correct connector specified for your source device, follow the

procedure below to connect the trigger-output jack on the rear of

the source device to the ZX-7/RX-7 rear panel TRIGGER INPUT.

To install the Trigger Cable:

• Power the controlling source and amplifier off.

• Connect the trigger cable to the controlling source and the

amplifier.

• After the connections are made, power on the controlling

source and then the amplifier. After the source unit is fully

powered up, the LED on the amplifier should be in the ON

state, BLUE. If the amplifier is in the standby mode, RED, press

the standby/on button on the front panel until the amplifier is

in the ON state, BLUE.

• Verify the trigger is working by putting the source unit into

standby mode. The amplifier after a short delay will also go into

the standby mode, RED LED.

• Once you have verified that the trigger cable is working, only

use the source unit to power on and off your amplifier.

When installing the trigger cable, never have the

controlling source or amplifier powered on. Doing so will

cause the trigger device to work improperly and could

cause damage to both the source and amplifier.

NOTE:

The trigger cable supplied has a 1/8” connector on both ends. In order for

this cable to be used with the MC-12HD or MC-8, you must modify the

cable. The cable has an insulated center conductor with a braided shield

surrounding it. These are protected by the outer black jacket. The inner

conductor is the positive (+) lead and the braided shield is the negative (-)

lead. Snip the connector off one end of the trigger cable and remove

about 3/4” of the outer black jacket. Be careful not to nick or cut the

braided shield strands. Carefully unweave the braided shield and twist the

loose strands into a tight group. Strip about 1/4” of the insulation off the

center conductor. Insert this into the (+) terminal of the powered source.

Insert the twisted group of shield braid wires into the (-) terminal of the

powered source. Fasten securely. You should also use an electrical meter if

possible.
