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

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

on the front panel of the ampliﬁer is

turned off (in the out position). Then, connect the supplied power cord

to the Power Connector

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

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

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.
