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.
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.
