Infra Red Control, Command Cable
The remote control for the XA 75LE uses Infra Red (IR)
to send commands to both speakers. Generally, both
speakers will see commands through uninterrupted dis-
tances of up to 30 feet. Sometimes, one of the speakers
might not see the IR signal, so we have included a cable
to transfer commands from one tower to the other.
You might fi nd a time where you are at the limits of
reception, with one speaker blocked, or perhaps aiming
toward one system and away from the other. In these
cases, the system that receives the commands will pass
them on to the other, thus assuring the best reception
and that the two speakers remain in sync.
Connect the supplied cable from speaker to speaker
through the jacks marked “remote link.” If a longer cable
is required for a special routing or for running wires
through walls, it can be custom-made using well-shield-
ed coaxial and standard mono 1⁄8-inch minijacks.
The control handset gives you control of bass level (in
2dB steps) of bass rolloff shape, and of treble level.
Turn On Mode
The XA 75LE include a feature for automatic turn on.
The subwoofer amplifi er will come out of its low-power
standby mode when it senses a signal. A multicolored
LED will designate what state the amplifi er is in. Yellow
indicates standby, and green indicates on. After the
signal ceases, the system will revert to standby mode in
approximately 8 to 10 minutes. Both speakers will not
necessarily turn off at the same moment. As an alterna-
tive to automatic turn on, the speaker can be set to be
always on. To choose between these two options, use
the switch marked “MUSIC SENSE-AUTO/ALWAYS ON.”
In some systems, the electrical noise fl oor (due to hum,
refrigerator, or furnace-turn-on pops, etc.) is such that
Music Sense- Auto turn on is erratic. In this case, we
recommend that the switch be set to ALWAYS ON and
manual switching via the main power switch be used.
Power On
The main power switch is situated below the power
input lead. It is a rocker-type switch marked with a ”1”
and a ”0.” Pressing the end marked ”1” will turn on the
main power to the system. Some people prefer to turn
off the main power if they know that they will be gone
from the house for an extended period of time.
