RX-975 AM/FM Stereo Receiver
INPUT SOURCE Buttons
Two rows of buttons duplicate the function
of the ten INPUT SOURCE buttons on the front
panel. Select an input source by pressing
the appropriate button. The AUX 1 and AUX
2 buttons correspond to the front panel
VIDEO 4 and VIDEO 5 buttons.
NUMERIC Buttons
Ten numeric buttons, labeled 0 through 9,
duplicate the function of the NUMERIC but-
tons on the front panel. Selects memorized
station presets.
Rear Panel Connections
The RX-975 provides rear panel connections
for five video sources, three audio sources,
and a phono input for use with a turntable.
These connections include standard RCA
audio inputs and outputs plus composite video
inputs and outputs.
The RX-975 includes two pairs of speaker
connections for the built-in power amplifier
as well as RCA preamp outputs for use with
external amplifiers. In addition, a compos-
ite video output connects the unit to your TV
monitor.
NOTE
: DO NOT plug any system compo-
nent into an AC source until system hookup
is complete and you are confident that all
component-to-component connections have
been properly made.
All video cables should have a 75
ohm impedance rating. Although con-
ventional audio interconnects will pass a
video signal, their construction and limited
bandwidth impose a performance penalty
because, in part, they do not adhere to the
75 ohm standard.
When making signal connections, make sure
that you always preserve proper channel con-
sistency, i.e. connect LEFT channels to LEFT
channel jacks and RIGHT channels to RIGHT
channel jacks. All RCA-type connections on
the RX-975 follow these standard color codes:
Left audio: RCA jack with white inset
Right audio: RCA jack with red inset
Video: RCA jack with yellow inset
Connect your audio-only source components
to these RCA inputs and outputs:
Phono Inputs and Phono
Ground
Connect the left and right output cables of
a turntable to this pair of RCA inputs. Con-
nect the ground wire from your turntable to
the phono ground lug, labeled GND.
CD Inputs
Connect the left and right analog outputs from
a CD player to the RCA input jacks labeled
CD.
Tape Inputs and Outputs
The RX-975 provides two sets of audio tape
connections labeled TAPE 1 and TAPE 2. Each
has a pair of inputs and a pair of record
outputs that allow recording on either tape
deck.
Connect the left and right analog outputs from
an audio tape deck to the TAPE 1 IN input
jacks. Connect the TAPE 1 OUT output jacks
to the INPUTS on the audio tape deck.
Connect a second tape deck to the TAPE 2
connections – the outputs of the tape deck
to the IN jacks on the RX-975 and the OUT
jacks on the RX-975 to the inputs on the tape
deck.
VIDEO 1 Inputs/Outputs
There are groups of connections for up to
five video source components. Each group
includes a pair of RCA analog audio inputs
and a composite video input. One group,
VIDEO 1, also includes a set of record out-
puts for sending audio and video signals to
a VCR.
Connect your VCR to the VIDEO 1 group
of inputs and outputs. This set of connections
allows recording.
Connect the analog audio outputs of the
VCR to the VIDEO 1 PLAY left and right RCA
audio jacks. Connect the VIDEO 1 REC left
and right RCA audio output jacks to the audio
inputs on the VCR.
Connect the RCA composite video output
of the VCR to the RCA composite video input
labeled VIDEO 1 PLAY.
Hookup the VIDEO 1 REC video output to
the RCA composite video recording input on
your VCR.
VIDEO 2 – 5 Inputs
These four sets of audio/video inputs allow
connection of four additional video compo-
nents such as a play-only VCR, DVD player,
LaserDisc player, or DSS satellite receiver.
Connect the RCA analog audio outputs of
the first video component to the left and right
RCA analog audio inputs labeled VIDEO 2.
Then, connect the RCA composite video
output of the video source to the correspond-
ing RCA composite connection labeled
VIDEO 2.
Repeat for additional components, using
VIDEO 3, VIDEO 4, and AUX/VIDEO 5.
NOTE
: Any of the video source inputs may
also be used for an audio-only source. Sim-
ply omit the video connection.
TV Monitor Output
The video output of the RX-975 sends the
video signal to your TV monitor. Connect the
TV MONITOR output to an RCA composite
video input on your television monitor. What-
ever input source is selected on the RX-975
will appear on screen.
Speaker Outputs
The RX-975 has a built-in stereo amplifier
for driving left and right speakers. There are
two pairs of connections on the back panel
which allow you to connect two pairs of
speakers (A and B) and select them with a
front-panel button.
NOTE
: The combined speaker impedance
must be a minimum of 4 ohms. If you are
driving just one pair of speakers (A or B
connections), use speakers with a nominal
impedance of 4 ohms or higher. If you are
driving two pairs of speakers (A and B) si-
multaneously, use speakers rated at 8 ohms
or higher.
