REMOTE POWER ON WITH EXTERNAL AC TO DC POWER CONVERTER
If your preamplifier, processor or receiver does not have a dedicated trigger jack, it is still possible to activate the unit for automatic power on when a switched outlet is available on the source device rear panel. To control the ZX-7/RX-7 in this instance, a small AC to DC power converter capable of delivering a 3.3V DC minimum to 24V DC maximum signal is required. The DC voltage should terminate in a standard 1/8”mini-plug.
How to make connections for remote power-on using external AC to DC Power converter:
1.Plug the AC adapter into a switched outlet that will be activated when you wish to have the amplifier power on. This may be the switched outlet at the rear of another A/V product.
2.Connect the 1/8 mini-plug from the adapter to the ZX-7/RX-7 rear panel TRIGGER INPUT. The ZX-7/RX-7 will now turn on and off automatically, depending on the status of the controlling device.
POWER CONNECTION SAFETY
After all audio and system connections have been made, connect the power cord to an AC power source. Be sure that the ZX-7/RX-7 is powered off and that the device connected to the remote trigger input is off when connecting the power cord and plugging it into an AC outlet.
WARNING 
Do not plug the ZX-7/RX-7 directly into the “Switched Accessory” outlet of another device! These outlets are intended for use with low current draw products such as tuners, CD players or cassette decks. These outlets are not designed to handle the high current draw of a power amplifier. Using these outlets for a power amplifier is a significant safety hazard.
SOURCE COMPONENT CONNECTIONS & OUTPUT SETTINGS
Make all connections before powering on the ZX-7/RX-7. It is also recommended that you power on the source components and processor in your system before powering on the ZX-7/RX-7. This avoids the possibility of any pops or transients from other components being amplified and sent to the speakers. Always start with a low volume level on the controller or preamplifier to avoid potential damage to the speakers.
All volume and level adjustments are made on your preamplifier, controller or surround processor. When using the ZX-7/RX-7 for the first time, you should re-set the output levels of the channels on your processor.
