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 GX-7 is
powered off and that the device connected to the remote trigger
input is off when connecting the power cord and plugging it in to
an AC outlet.
Do not plug the GX-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.
Note:
It is not recommended that you connect other power amplifiers or
products with a high current draw, to the same AC power circuit as the
GX-7, unless they are used with the remote power-on and sequencing
system. The simultaneous power-on of multiple amplifiers on the same
circuit may cause circuit breakers to trip due to the high current draw.
SOURCE COMPONENT CONNECTIONS & OUTPUT
SETTINGS
Make all connections before powering on the GX-7. It is also recom-
mended that you power on the source components and processor
in your system before powering on the GX-7. This avoids the possi-
bility 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 GX-7 for the first
time, you should re-set the output levels of the channels on your
processor. Experiment to ensure that your system components are
properly matched with the GX-7.
PROTECTION MODE
The GX-7 is equipped to protect itself against potentially damaging
conditions such as overheating, miswiring and electrical failures.
Under such conditions, the GX-7 will enter a protection mode.
When this occurs, the unit will mute to protect itself and speakers
from potential damage.
If the GX-7 enters protection mode (mutes itself):
1. Immediately power off the unit with the rear panel master
power switch and disconnect the AC power cord.
2. Examine all speaker connections to ensure there are no shorts.
3. Power on the GX-7. If the unit continues to mute, contact Lexicon
customer service for assistance.
