Basic Operation
2-5
5 AC POWER CONNECTOR
The AC input connector provides power to the unit with the
supplied power cord. Do not use an extension cord.
CAUTION!
Never make or break connections to the GX-7 unless the
GX-7 and all associated components are powered off.
6 FUSE HOLDER
The GX-7 uses internal fuses to protect itself and the speakers from
possible damage. In the event that a replacement fuse is needed, be
sure that a fuse of the original rating is used. If a fuse continues to
fail, the GX-7 may have developed a fault. In this event, contact
Lexicon customer service.
POWER CONTROL CONNECTIONS
The GX-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
To connect to a 12V trigger jack:
Using an accessory cable with a 3.5mm mono mini-plug on each
end, connect the trigger-output jack on the rear of the source
device to the GX-7 rear panel TRIGGER INPUT.
When these connections are made, the GX-7 will automatically
power on whenever the triggering device is turned on.
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 GX-7 in this instance, a small AC to DC
power converter capable of delivering a 6 to 12 volt DC signal is
required. The DC voltage should terminate in a standard 3.5mm
type mini plug.
To connect to an 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 an AC receiver or other audio
component.
2. Connect the 3.5mm mini-plug from the adapter to the GX-7
rear panel TRIGGER INPUT. The GX-7 will now turn on and off
automatically, depending on the status of the controlling
device.
