Audio Distribution
AD-8
The AD-8 Audio Distribution System combines a 16
channel audio amplifier with a matrix-switching pre-
amplifier. Perfect in larger residential and commercial
installations where flexibility is important, the ability to
listen to eight different audio sources in any zone will
keep everyone happy. Up to four of the audio sources
can even come from other areas, so sources like an
iPod
®
or PC can be accessed where they are used,
away from the rack. Meanwhile, the integrated Cool
Power
®
amplifier keeps the beat with 25 watts per
channel of crystal clear sound. Infrared and one-way
RS-232 provide independent volume and tone controls
in all output zones, while complete control is provided
via two-way RS-232 when combined with RTI control
solutions.
When the job grows, the AD-8 can expand along with
it. The eight zone outputs can easily be expanded by
stacking up to eight AD-8’s together, for a maximum
of 64 zones. The AD-8 from RTI will provide you with
clean, stable, reliable power you can count on for years
to come.
