Getting Started
Thank you for purchasing the Rotel RB-1552 or RB-1582 Stereo Power 
Amplifier. When used in a high-quality music or home theater system, 
your Rotel amplifier will provide years of musical enjoyment.
The RB-1552 and RB-1582 are high-power, two-channel power 
amplifiers, providing the highest level of audio performance. Discrete 
output devices, a massive power supply, premium components, 
and Rotel’s Balanced Design ensure superb sound quality. High 
current capability allow the RB-1552 and RB-1582 to drive the most 
demanding loudspeakers.
Be aware that the RB-1552 and RB-1582 are capable of high power 
levels, in excess of 130 watts and 200 watts respectively per channel. 
Make sure that your speakers can handle the power of the amplifier. 
If in doubt about your speakers, ask your local Rotel audio dealer for 
advice.
These amplifiers are straightforward in their installation and operation. 
If you have experience with other stereo power amplifiers, you 
shouldn’t find anything perplexing. Plug in a pair of high-quality 
RCA cables from your preamp into the amplifier inputs, wire up your 
speakers, and enjoy. 
A Few Precautions
Please read this manual carefully. In addition to basic installation and 
operating instructions, it provides valuable information on various 
system configurations as well as general information that will help 
you get optimum performance from your system. Please contact your 
authorized Rotel audio dealer for answers to any questions you might 
have. In addition, all of us at Rotel welcome your questions and 
comments. 
Save the shipping carton and all enclosed packing material for future 
use. Shipping or moving the amplifier in anything other than the 
original packing material may result in severe damage.
Fill out and send in the owner’s registration card packed with the 
amplifier. Or register your amplifier on the Rotel web site, 
www.Rotel.com/register. Also 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 RB-1552 and RB-1582 generate heat as part of their normal 
operation. The heat sinks and ventilation openings in the amplifier are 
designed to dissipate this heat. The ventilation slots in the top cover 
must be open. 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, remember the weight of the amplifier when you select an 
installation location. Make sure that the shelf or cabinet can support its 
considerable bulk. Again, use common sense.
AC Power and Control
AC Power Input
7
Because of its high power rating, the amplifier can draw considerable 
current. Therefore, it should be plugged directly into a wall outlet. The 
RB-1582 must be plugged into a 3-pin polarized outlet. The RB-1552 
may be plugged into either a 2-pin or a 3-pin outlet. Do not use an 
extension cord. A heavy duty multi-tap power outlet strip may be used 
if it (and the wall outlet) is rated to handle the current demanded by 
the amplifier and all the other components connected to it. 
Be sure the Power Switch
1
on the front panel of the amplifier is
turned off (in the out position). Then, connect the supplied power cord 
to the Power Connector 
7
on the back panel of the amplifier and to
the AC power outlet.
Your amplifier is configured at the factory for the proper AC line 
voltage in the country where you purchased it (either 120 volts AC or 
230 volts AC with a line frequency of either 50 Hz or 60 Hz). The AC 
line configuration is noted on a decal on the back panel.
Note: Should you move your amplifier to another country, it is
possible to reconfigure it for use on a different line voltage. Do not
attempt to perform this conversion yourself. Opening the enclosure
of the amplifier exposes you to dangerous voltages. Consult a
qualified service person or the Rotel factory service department for
information.
If you are going to be away from home for an extended period of time 
such as a month-long vacation, it is a sensible precaution to unplug 
your amplifier (as well as other audio and video components) while 
you are away.
Power Switch and Power Indicator
1
The power switch is located on the front panel of your amplifier. To 
turn the amplifier on, push the switch in. The ring around the switch 
will light, indicating that the amplifier is turned on. To turn the amplifier 
off, push the button again and return it to the out position. 
Trigger ON/OFF Mode Selector
3
The amplifier provides the option for manual or automatic power on/
off operation. These modes are selectable using a toggle switch on the 
back panel. 
With the switch in the +12V TRIGGER ON position, the amplifier is 
turned on automatically when a 12V trigger signal is present at the 
3.5 mm Jack of TRIGGER IN on the rear panel. The amplifier will go 
into standby mode if the +12V signal is not present. 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 amplifier, 
regardless of whether or not a trigger signal is present.
