Getting Started
Thank you for purchasing the Rotel RMB-1066
Six-Channel Power Amplifier. When used in
a high-quality music or home theater system,
your Rotel amplifier will provide years of
musical enjoyment.
The RMB-1066 is a sophisticated six-channel
power amplifier. Discrete output devices, a
massive power supply with toroidal trans-
former, premium components, and Rotel’s
Balanced Design ensure superb sound qual-
ity. High current capability allows the RMB-
1066 to drive difficult speaker loads with ease.
Operating Features
• Three pair of amplifier channels, any of
which can be bridged for mono operation
(back panel switchable). Possible configu-
rations: 6, 5, 4, or 3 channel operation.
• User selectable power on/off configuration:
manual, automatic signal sensing, or con-
trolled by remote 12 volt trigger signal.
• Front panel input level controls.
• Front panel LEDs indicate Bridged Mono
mode for each pair of amplifier channels.
• Protection circuitry with front panel
indicators.
• Signal link output to pass-through the in-
put signal to another component.
A Few Precautions
Please read this manual carefully. In addition
to installation and operating instructions, it
provides information on various RMB-1066
system configurations. Please contact your au-
thorized Rotel dealer for answers to any ques-
tions you might have. In addition, all of us at
Rotel welcome your questions and comments.
Save the RMB-1066 shipping carton and
packing material for future use. Shipping or
moving the RMB-1066 in anything other than
the original packing material may result in
severe damage to your amplifier.
Be sure to keep the original sales receipt. It
is your best record of the date of purchase,
which you will need in the event warranty
service is ever required.
Placement
The RMB-1066 generates heat as part of its
normal operation. The heat sinks and venti-
lation openings in the amplifier are designed
to dissipate this heat. The ventilation slots in
the top cover must be unobstructed. There
should be 10 cm (4 inches) of clearance
around the chassis, and reasonable airflow
through the installation location, to prevent
the amplifier from overheating. Likewise, re-
member the weight of the amplifier when you
select an installation location. Make sure that
the shelf or cabinet can support its weight.
