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.
