However, Rotel amplifi ers are designed to work into any speaker
impedance between 8 and 4 ohms, and with all the channels working
up to their full power. Because the Rotel design is optimized for use
with all channels operating together, Rotel is able to specify the true
power output for all channels.
This can be important for your enjoyment, too. When watching
movies, it’s nice to have the amplifi er able to reproduce full power into
all the channels at the same time, especially in the case of a volcano
exploding!
Getting Started
Thank you for purchasing the Rotel RMB-1565 or RMB-1575 Five-
Channel Power Amplifi er. When used in a high-quality music or home
theater system, your Rotel amplifi er will provide years of musical
enjoyment.
The RMB-1565 and RMB-1575 are sophisticated fi ve-channel power
amplifi ers. Their Class D amplifi er circuitry, switching power supply,
premium components, and Rotel’s Balanced Design ensure superb
sound quality. High current ` allows the RMB-1565 and RMB-1575 to
drive diffi cult speaker loads with ease.
Operating Features
• Five
amplifi er channels
• User selectable power on/off confi guration: manual, or controlled
by remote 12 volt trigger signal
• Protection circuitry with front panel indicator
A Few Precautions
Please read this manual carefully. In addition to installation and
operating instructions, it provides information on various system
confi gurations. Please contact your authorized Rotel dealer for
answers to any questions you might have. In addition, all of us at Rotel
welcome your questions and comments.
Save the amplifi er shipping carton and packing material for future use.
Shipping or moving the amplifi er in anything other than the original
packing material may result in severe damage to your amplifi er.
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-1565 and RMB-1575 generate heat as part of their normal
operation. The heat sinks and ventilation openings in the amplifi er 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 airfl ow through the installation
location, to prevent the amplifi er from overheating. Likewise,
remember the weight of the amplifi er when you select an installation
location. Make sure that the shelf or cabinet can support its weight.
AC Power and Control
AC Power Input
7
The amplifi er is supplied with the proper AC power cord. Use only this
cord or an exact equivalent. Do not use an extension cord. A heavy
duty multi-tap power outlet strip may be used, but only if it is rated to
handle the current demand of the amplifi er.
The RMB-1565 will automatically confi gure itself for the proper AC line
voltage rating, from 110 volts to 240 volts, at 50/60Hz. No setting is
required to match the unit to your local voltage.
The RMB-1575 is confi gured at the factory for the proper AC line
voltage in the country where you purchased it (USA: 120 volts/60 Hz,
Europe: 230 volts/50 Hz). The AC line confi guration is noted on a
label on the back panel.
Note:
Should you move your RMB-1575 to another country, it is
possible to configure your amplifier for use on a different line voltage.
Do not attempt to perform this conversion yourself. Opening the
enclosure of the RMB-1575 exposes you to dangerous voltages.
Consult a qualified technician or the Rotel factory service department
for information.
Plug the supplied cord into the AC INPUT receptacle
7
on the back
panel of the unit. After all connections have been made, plug the other
end into an appropriate AC wall outlet.
Note:
If you are going to be away from home for an extended period
of time, it is a sensible precaution to unplug your amplifier.
Power Switch and Indicator
1
The Power Switch is located on the front panel. To turn the amplifi er on
(or to activate either of the optional automatic power-on modes), push
the switch in. The ring around the switch will light, indicating that the
amplifi er is turned on. To turn the amplifi er off, push the button again
and return it to the out position.
Turn On/Off Mode Selector
6
The amplifi er can be turned on and off manually, or automatically by
using its “12V Trigger” system. The Turn On/Turn Off Mode selector
switch selects which method is used.
• With the switch in the OFF position, the amplifi er is turned on or off
manually using the front panel power switch. Use this mode if you
are using a switched AC outlet to control power to the amplifi er.
• With the switch in the 12V TRIG position, the amplifi er is turned
on automatically when a 12 volt trigger signal is applied to
the 3.5mm jack labeled IN. The front panel POWER SWITCH
overrides this function. It must be ON for the +12V trigger to work.
Turning the switch OFF cuts power to the amplifi er, regardless of
whether or not a trigger signal is present.
