RB-993
Getting Started
Thank you for purchasing the Rotel RB-993 power amplifier When
used in a high-quality music or home theater system, your Rotel
amplifier will provide years of musical enjoyment.
The RB-993 is a powerful three-channel power amplifier, ideal for
driving the front and center speakers in an audiophile quality
home theater system. The RB-993 provides the highest level of au¬
dio performance. Discrete output devices, low negative feedback,
and Rotel's Balanced Design ensure superb sound quality. Its high
current capability allows the RB-993 to drive the most demanding
loudspeakers.
Be aware that the RB-993 is capable of high power levels, in ex¬
cess of 200 watts per channel. Make sure that your speakers can
handle the power of the RB-993. If in doubt about your speakers,
ask your local Rotel audio specialist for advice.
The RB-993 is straightforward in its installation and operation. If
you have experience with other power amplifiers, you shouldn't
find anything terribly perplexing. Plug in three sets of high-quality
RCA cables from your preamp into the amplifier inputs, wire up
your speakers, and enjoy. Alternatively, the RB-993 provides an
optional set of "balanced" inputs for use with preamps or proces¬
sors that offer these low-noise XLR-connections.
A Few Precautions
Please read this manual carefully. In addition to basic installation
and operating instructions, it provides valuable information on
various RB-993 system configurations as well as general informa¬
tion that will help you get optimum performance from your system.
Please contact your authorized Rotel specialty retailer for an¬
swers to any questions you might have. In addition, all of us at
Rotel welcome your questions and comments.
Save the RB-993 shipping carton and all enclosed packing mate¬
rial for future use. Shipping or moving the RB-993 in anything
other than the original packing material may result in severe dam¬
age to your amplifier.
Fill out and send in the owner's registration card packed with the
RB-993. 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
Because of its high power output, the RB-993 may generate con¬
siderable heat. The heat sinks and ventilation openings in the am¬
plifier are more than capable of dissipating this heat under normal
conditions, but don't smother your amplifier. There must be ad¬
equate clearance around the chassis. The ventilation slots in the
top cover must be unblocked, and there must be reasonable air¬
flow around the amplifier. Use common sense when placing the
amplifier in a cabinet or when stacking other equipment.
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
Q
Because of its high power rating, the RB-993 can draw consider¬
able current. Therefore, it should be plugged directly into a 2-pin
polarized wall 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 RB-993 and all the
other components connected to it.
Be sure the power switch on the front panel of the RB-993 is
turned off (in the "out" position). Then, connect the supplied power
cord to the AC power receptacle on the rear of the unit and the
AC power outlet.
NOTE: You may find it convenient to use a remote power control
accessory, such as Rotel's RLC-900 Line Conditioner, to turn on
and off your entire system automatically Alternately, some pream¬
plifiers have a switched outlet that can handle the current de¬
mands of the RB-993. However, again be sure that the switched
outlet is up to the task.
Your RB-993 is configured at the factory for the proper AC line
voltage in the country where you purchased it (either 115 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 RB-993 amplifier to another country,
it is possible to reconfigure your amplifier for use on a different
line voltage. Do not attempt to perform this conversion yourself.
Opening the enclosure of the RB-993 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 compo¬
nents) while you are away.
Power Switch O and Power Indicator ©
The power switch is located in the center of the front panel of
your amplifier. To turn the amplifier on, push the switch in. The
LED indicator above the switch will light, indicating that the ampli¬
fier is turned on. To turn the amplifier off, push the button again
and return it to the "out" position.
NOTE: If you are using the Rotel RLC-900 AC Line Conditioner or
other switched outlet to turn on and off your amplifier, you can
leave the power switch in the "on"position.
