This wireless transmi tter and receiver syst em
use the latest 5.8 GHz technology that travels
through walls, floors, ceilings and other
obstacles, delivering high quality sound for
your home theater system’s rear surround
speakers. Using thi s wireless system, you w ill
experience movie theater quality sound in
your own home using your current home
theater surround system. We have designed
this system for use w ith yo ur s urro und so un d
home theater system to enhance the quality
of the sound and balance coming from your
speakers. You can now eliminate running
long speaker wires through your rooms, while
enhancing the sound coming from those
speakers.
How It Works
The transmitter converts the audio signal
from your audio source into a 5.8GHz radio
frequency and transmits it to the receiver.
The receiver will pick up the best signal from
one of its two antennas and convert the
signal back to its original form. Using a
powerful amplifier, the signal is passed to
your connected rear surround speakers. The
result is an enhanced sound quality resulting
in a theater quality surround sound
experience.
This system is compatible with most audio
sources such as televisions, VCRs, stereo
receivers/amplifiers, CD player s, and
personal stereos. This unit allows you to
listen to wired speakers in any room in the
house when a two-channel source is
connected to the transmitter. The audio link
system also tracks the volume setting of your
audio source, so that when you increa se or
decrease the volume on the audio source,
the link’s connected speakers respond
accordingly.
Some of this system’s other features include:
• 6 user-adjustable chann els
• 2 diversity receiver antennas for optimal
audio reception.
• Adjustable speaker and line level input
control
• 256 option personal ID Code
• Ideal for Dolby 5.1 Digital, Pro Logic II,
DTS, SCAD and DVD Audio Systems
• Provides digital transmission for superb
audio clarity
• Immune to interference from microwave
ovens and other popular 2.4GHz
equipment
