ROTEL RTC965 - Manual (Page 18)

SURROUND SOUND TUNER PREAMPLIFIER RTC-965
18
These digital inputs are available for VIDEO 2 (coaxial), VIDEO 3
(coaxial), VIDEO 4 (optical), and AUX/VIDEO 5 (optical).
To use the digital inputs, connect the appropriate cable (optical or
coaxial) from the digital output of your source component to the
corresponding DIGITAL INPUT on the RTC-965. Make sure that if
you have connected the analog signals from a source to VIDEO 2,
that you also connect its digital output to VIDEO 2, etc.
Even when using digital connections, you should still make the
analog input connections described above. The analog connec-
tion is necessary should you wish to record from that source com-
ponent to an audio tape deck or VCR.
5.1 Channel Audio Input 36
This female DB25 25-pin input connects six discrete channels of
analog information from an outboard processor in a single cable.
Many external adaptors provide a choice of RCA or DB25 outputs.
We suggest that you use a DB25-to-DB25 cable to reduce the
number of cables and to insure proper channel-to-channel conti-
nuity. If your external adaptor does not have a DB25 output, you
will need to purchase a multi-RCA to DB25 adaptor cable from
your authorized Rotel dealer. Make sure to observe proper chan-
nel continuity. See Figure 4 for DB25 pin assignments.

Rear Panel Output Signal
Connections
This section of the manual provides complete information on the
audio and video signal output connections on the rear panel of the
RTC-965. These are used for routing the output signals to televi-
sion monitors, audio amplifiers, and recording devices. For conve-
nience, each topic begins with an overview of the particular
connection, followed by detailed hookup instructions.
TV Monitor Output 39
The video output of the RTC-965 sends the video signal to your TV
monitor. Both RCA composite and S-Video connectors are pro-
vided. Simply connect the TV MONITOR output, either RCA com-
posite or S-Video, to an input on your television monitor. Whatever
input source is selected on the RTC-965 will appear on screen.
RCA Preamp Outputs 27
The RTC-965 provides a set of RCA preamp audio outputs: one for
a powered subwoofer and five more (FRONT LEFT/FRONT RIGHT/
CENTER/RIGHT REAR/LEFT REAR) that allow you to use external
amplifiers in place of one or more of the built-in amps.
To hook up a powered subwoofer, connect a standard RCA audio
cable from the SUBWOOFER OUTPUT jack to the input on the
subwoofer’s power amp.
To hook up the RCA main audio outputs, connect a standard audio
cable from each output to the input of the amplifier channel that
will power the corresponding speaker. In a full home theater sys-
tem using external amplifiers for all channels, you will need to
make six different connections corresponding to the six speakers
(left front, center front, right front, left surround, right surround,
and subwoofer).
It is important to make sure that you have the correct output con-
nected to the proper amplifier channel (front right, left rear, etc.).
Take your time.
5.1 CHANNEL Preamp Outputs 28
As an alternative to the RCA preamp outputs , the RTC-965 also
provides a male DB25 multi-pin output connector which carries all
six output channels in a single cable. The DB25 output connector
provides exactly the same signal as the RCA outputs, but is more
convenient for use with Rotel, or other, multichannel amplifiers
equipped with a matching DB25 input. Choose whichever is most
convenient for your system hookup.
To use the DB25 output connections, simply connect a female-to-
male DB25 audio cable from the output of the RTC-965 to the
matching input on the multichannel power amplifier. See Figure 4
at the front of this manual for DB25 pin assignments.

Rear Panel Antenna Connections
The RTC-965 requires two antennas to receive radio signals, one
for AM and one for FM (MW and LW in some countries). Most us-
ers will get acceptable reception using the indoor antennas which
are supplied with the RTC-965. Instructions for hooking up these
antennas follow.
Note: If you are located a considerable distance from the radio
transmitters, you may choose to use outdoor antennas to improve
reception. Outdoor antenna systems can be dangerous if they are
not properly grounded and should always be installed by a profes-
sional contractor familiar with the electrical code requirements in
your local area.
AM Loop Antenna 26
The RTC-965 includes a loop antenna to receive AM radio signals.
Remove this antenna from the box and locate it near the RTC-965.
Connect the 300 ohm twin-conductor wire from the loop antenna
to the pair of screw terminals labeled AM LOOP, attaching one
wire to each terminal. It does not matter which wire attaches to
which terminal, but make sure that the connections are solid and
that the two wires do not touch.
You may need to rotate or otherwise reorient the antenna to find
the best position.
