Rear Panel Input Connections

INPUT: This indication appears only when an ANALOG source in- put is selected. It shows the current INPUT LEVEL setting for the active source input and can be adjusted with the front panel IN- PUT LEVEL buttons. This change is not temporary. It is memorized and will be recalled each time that source input is selected.

This section of the manual provides complete information on all of the audio and video signal input connections on the rear panel of the RSP-975. For convenience, each topic begins with an over- view of the particular connection, followed by detailed hookup in- structions.

Note: DO NOT plug any system component into an AC source until system hookup is complete. Wait to apply power until you’re con- fident that all component-to-component connections have been properly made.

All video and digital audio cables should have a 75 ohm imped- ance rating. Because the video and digital cable standards are as close as they are, you can safely use a video cable for digital au- dio data transmission and, conversely, a digital audio cable for video data transmission. We strongly advise that you NOT substi- tute a conventional analog audio interconnect cable for either digital or video.

Source Inputs 26

These eight sets of RCA-type inputs (TUNER, CD, TAPE, AUX, DVD, VIDEO 1, VIDEO 2, and VIDEO 3) accept line level audio and com- posite video signals from source components. The first four inputs are audio-only, the other four source inputs accept both left and right channel audio plus a video signal.

All RCA-type connections on the RSP-975 follow these standard color codes:

Left channel audio	= RCA jack with white inset
Right channel audio	=	RCA jack with red inset
Composite video	=	RCA jack with yellow inset

Connect the OUTPUTS of your source components to the appro- priate INPUTS on the RSP-975. For example, if your system in- cludes a CD player, connect its left and right channel analog outputs to the RSP-975’s CD inputs. If your system includes a video source, connect its analog audio outputs to one of the RSP-975’s VIDEO audio inputs and its video composite RCA output to the cor- responding composite RCA video input.

Digital Inputs 24

The RSP-975 features a D/A conversion capability which allows it to accept digital input signals from source components. These in- clude digital signals from CD players, satellite TV receivers, and

5.1channel Dolby Digital signals from DVD players. The D/A auto- matically senses and adjusts to the correct sampling rates.

RSP-975

To take full advantage of the built-in digital decoding capability, the RSP-975 accepts digital signals from up to four different source components in a number of formats. The digital inputs are as follows:

OPTICAL: This input allows connection of a standard optical digi- tal output from a CD player or other source component. Requires an optical digital cable.

COAX 1 and COAX 2: Two standard coaxial digital connectors for use with the digital output of any component (CD player, Satellite TV, etc.)

DVD: Standard coax digital connection for use with Dolby Digital DVD players.

To use the digital inputs, simply connect the appropriate cable from the digital output of your source component to the corre- sponding digital input on the RSP-975.

It is necessary to select the appropriate digital (or analog) input for each component. Once the selection is made, it is memorized so that simply selecting a SOURCE INPUT activates the appropri- ate audio input. This procedure is detailed in the DIGITAL INPUT button section of this manual.

5.1 CH INPUT 20

This 25-pin input connects six discrete channels of analog infor- mation from an outboard processor (DTS, for example).

External adaptors may provide both RCA and 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 continuity.

If your external adaptor does not have a DB25 output, you will need to purchase a multi-RCA to DB25 adaptor cable from your Rotel retailer. Make sure to observe proper channel continuity.

REMOTE EXTERNAL IN Jack 22

This 3.5 mm jack accepts a remote infrared sensor which dupli- cates the function of the front panel IR sensor in installations where the front panel sensor could be blocked by a cabinet. See your authorized Rotel dealer for a selection of remote sensors that will work with your RSP-975.

Rear Panel Output Connections

This section of the manual provides complete information on the audio and video signal output connections on the rear panel of the RSP-975 which are used for routing the output signals to a televi- sion monitor, audio amplifiers, and recording devices. For conve- nience, each topic begins with an overview of the particular connection, followed by detailed hookup instructions.
