The RB-1590 is a high-power, two channel power amplifier, providing the
highest level of audio performance. A massive power supply, premium
components, and Rotel's Balanced Design ensure superb sound quality.
High current capability allows the RB-1590 to drive the most demanding
loudspeakers.
Be aware that the RB-1590 is capable of high power levels, in excess of 350
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.
This amplifier is straightforward in its installation and operation. If you have
experience with other stereo power amplifiers, you shouldn't find anything
perplexing. Simply plug in the associated components and enjoy.
A Few Precautions
WARNING: To avoid potential damage to your system, turn off ALL the
components in the system when connecting or disconnecting the loudspeakers
or any associated components. Do not turn the system components back on
until you are sure all the connections are correct and secure. Pay particular
attention to the speaker wires. There must be no loose strands that could
contact the other speaker wires, or the chassis of the amplifier.
Please read this manual carefully. In addition to basic installation and
operating instructions, it provides valuable information on various RB-1590
system configurations as well as general information that will help you get
optimum performance from your system. 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 RB-1590 shipping carton and all enclosed packing material for
future use. Shipping or moving the RB-1590 in anything other than the
original packing material may result in severe damage that is not covered
by the warranty.
If included in the box please fill out and send in the owner's registration
card. 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 required.
Placement
The RB-1590 generates heat as part of its 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.
Remember the weight of the amplifier when you select an installation location.
Make sure that the shelf or cabinet can support it. We recommend installing
the unit in furniture designed to house audio components. Such furniture is
designed to reduce or suppress vibration which can adversely affect sound
quality. Ask your authorized Rotel dealer for advice about component
furniture and proper installation of audio components.
AC Power and Control
AC Power Input

Your amplifier is configured at the factory for the proper AC voltage in the
country where you purchased it, either 120 volts or 230 volts. The AC line
configuration is noted on a decal on the back panel.
NOTE: Should you move your amplifier to another country, it may be
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.
NOTE: Some products are intended for sale in more than one country and
as such are supplied with more than one AC cord. Please only use the one
appropriate for your country/region.
Because of its high power rating, the amplifier can draw considerable current.
Therefore, it should be plugged directly into a wall outlet. The RB-1590 must
be plugged into a 3-pin polarized 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

off (in the "out" position). Then, connect the supplied power cord to the
Power Connector

on the rear panel of the unit and the AC power outlet.
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 the RB-
1590 (as well as other audio and video components) while you are away.
Power Switch and Power Indicator
The power switch is located on the left side of the front panel. To turn the
amplifier on, push the switch in. The ring around the switch will light up,
indicating that the amplifier is turned on. To turn the amplifier off, push the
button again and return it to the "out" position.
NOTE: Place the self adhesive ring over the light surrounding the power
switch if the blue light is too bright.
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
connector 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.
12V Trigger Input and Output
The connector labeled IN is for connecting the 3.5mm Plug/Cable carrying
a +12 volt trigger signal to turn the amplifier on and off. To use this feature
the 12V trigger toggle switch must be set to the ON position. This input
accepts any control signal (AC or DC) ranging from 3 volts to 30 volts.
