STEREO INTEGRATED AMPLIFIER RA-985BX
Auxiliary Power Outputs 23
NOTE: Normally the signal supplied to the Recorder Outputs is se-
lected by the Recording Selector 12 . However when the Second
Zone output function is used, the Recording Selector becomes the
source selector for the Second Zone.
North American models of the RA-985BX have two switched out-
lets on the back panel. Power is available from these outlets when
the RA-985BX is turned on. Power to these outlets is turned off
when the RA-985BX is in Standby mode. These outlets can provide
up to a total of 400 watts. They are appropriate for supplying
power to signal sources, such as CD players, tuners, or tape
decks. They should not be used for power amplifiers. Connecting
components that will draw more than 400 watts to these outputs
could damage the Standby switch in the RA-985BX.
Second Zone Output Connection 17
See Figure 3 for the Second Zone output connection illustration.]
This output (when used with an additional power amplifier and
speakers) lets the RA-985BX provide sound to another part of your
home. You can listen to a different signal source from the one be-
ing played by the main system or to the same source. See the
Second Zone Operation section for more information.
Input Signal Connections 15
See Figure 1 for input connection illustration.]
The RA-985BX has conventional RCA type input connectors, the
type found on nearly all audio equipment.
Preamp/Power Amp Jumpers 18
Note: To prevent loud noises that neither you nor your speakers
will appreciate, make sure the system is turned off when you
make any signal connections.
These connectors, labeled ”Pre Out” and “Main In”, are normally
connected by a set of solid metal jumper connectors. They pro-
vide a convenient insertion point for virtually any type of signal
processor. To use these connectors, pull out the jumper connec-
tors. Using high quality cables, connect the “Pre Out” connectors
to the inputs of the signal processor. Connect the outputs of the
signal processor to the “Main In” connectors.
All the inputs of the RA-985BX are “line level’ inputs. These are
appropriate for connecting components such as CD players, Hi Fi
or NICAM Stereo video cassette recorders, tuners for audio or
video, Laser Disc players or the analog output from a CD ROM
drive. If you want to use a phonograph with the RA-985BX, an ex-
ternal phono equalizer, such as the Rotel RQ-970BX must be used.
One of the most common uses for these connectors is to incorpo-
rate a surround sound processor into the system. Typically the
front channel outputs from the signal processor are connected to
the “Main In” of the RA-985BX. The other outputs from the signal
processor are connected to other power amplifiers and speakers.
The Left and Right channels are clearly labeled and should be
connected to the corresponding channels of the source compo-
nent. The Left RCA connectors are white, the Right connectors
are red. Use high quality RCA cables for connecting input source
components to the RA-985BX. Ask your authorized Rotel dealer for
advice about cables.
Cassette Remote Connector 19
Some Rotel cassette decks can be operated by the RR-927 remote
control that come with the RA-985BX. To use this feature connect
a standard 8-pin DIN type cable between the Cassette Remote
connector on the back of the RA-985BX and the connector on the
back of the cassette deck. Control signals from the RR-927 remote
control are pick up by the Remote Sensor on the front of the RA-
Recorder Connections 16
See Figure 2 for recorder connection illustration.]
The Tape 1 and Tape 2 inputs and outputs can be connected to
any record/playback device that accepts standard line level ana-
log input and output signals. Typically that will be a conventional
85BX and passed to the cassette deck via the cable.
When connecting a recorder to the RA-985BX remember that the
outputs of the recorder must be connected to the tape inputs of
the RA-985BX. Similarly the tape outputs of the RA-985BX must be
connected to the inputs of the recorder. As with other sources be
sure to connect the Left and Right channels of each device to the
proper channels on the associated components. Use high quality
connecting cables to prevent loss of sound quality.
Remote Sensor Extension System 20
These connectors, when used in conjunction with Xantech™
brand Video Link™ IR signal pick ups and repeaters (sold sepa-
rately by custom system installers), enable the RA-985BX to pick
up IR remote control signals and distribute them to other compo-
nents. Contact your authorized Rotel dealer for more information.
