In addition the RA-985BX has several features that enhance its
ease of operation and its system configuration flexibility. A full
function remote control is provided that can operate several other
Rotel tuners and cassette decks in addition to the RA-985BX. An
IR remote control signal input/output system is provided. This fea-
ture, when used in conjunction with Xantech™ brand Video Link™
IR signal pick ups and repeaters (sold separately by custom sys-
tem installers), enables the RA-985BX to pick up IR remote control
signals and distribute them to other components. A preamp/power
amp jumper set is provided that makes it easy to connect external
components, such as surround sound processors. The unique
Second Zone output system (when used with an additional power
amplifier and speakers) lets the RA-985BX provide sound to an-
other part of your home. You can even listen to a different signal
source from the one being played by the main system.
Be sure to keep the power cords, digital signal cables and regular
audio signal cables in your installation away from each other. This
will minimize the chance of the regular audio signal cables pick-
ing up noise or interference from the power cords or digital
cables. Using only high quality, shielded cables will also help to
prevent noise or interference from degrading the sound quality of
your system. If you have any questions see your authorized Rotel
dealer for advice about the best cable to use with your system.
AC Power and Control
The main functions of the RA-985BX are easy to install and use. If
you have experience with other stereo systems, you shouldn’t find
anything perplexing. Simply plug in the associated components
AC Power Input 24
Because of its high power rating, the RA-985BX can draw consid-
erable 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 RA-985BX
and all the other components connected to it.
A Few Precautions
Please read this manual carefully. It provides information on how
to incorporate the RA-985BX into your system as well as informa-
tion that will help you get optimum sound performance. Please
contact your authorized Rotel dealer for answers to any questions
you might have. In addition, all of us at Rotel welcome your ques-
tions and comments.
Note: Do not connect the power cord for a power amplifier to the
auxiliary power outlets on the RA-985BX. Power amplifiers often
draw more power than these outlets can provide.
Your RA-985BX 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.
Save the RA-985BX shipping carton and all enclosed packing ma-
terial for future use. Shipping or moving the RA-985BX 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
RA-985BX. 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.
Note: Should you move your RA-985BX amplifier to another coun-
try, it is possible to reconfigure it for use on a different line volt-
age. Do not attempt to perform this conversion yourself. Opening
the enclosure of the RA-985BX exposes you to dangerous volt-
ages. Consult a qualified service person or the Rotel factory ser-
vice department for information.
Like all audio components that handle low-level signals, the
RA-985BX can be affected by its environment. Do not stack the
RA-985BX on top of a power amplifier. This will minimize the chance
it will pick up hum or interference.
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.
The RA-985BX 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 loca-
tion, to prevent the amplifier from overheating.
and Power Indicator
The Power Indicator light above the Standby button is always illu-
minated when the RA-985BX is connected to a “live” AC outlet.
When the Power/Standby is pressed the RA-985BX is turned on
and the Volume Control LED is illuminated. Pressing the Standby
switch again will put the RA-985BX in “standby” mode and the
Volume Control LED is turned off.
Remember the weight of the amplifier when you select an installa-
tion location. Make sure that the shelf or cabinet can support its
considerable bulk. We recommend installing the RA-985BX in furni-
ture designed to house audio components. Such furniture is de-
signed 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.
