Remote Sensor, Master Volume Control 3

DIGITAL SURROUND SOUND PROCESSOR RSP-975

Push the front panel STANDBY button (or the handheld remote POWER button) to fully activate the RSP-975. You'll see other LEDs light up and the STANDBY LED will go out. Push the STANDBY switch again to deactivate the RSP-975.

Note: The STANDBY switch controls the rear panel AC outlet. When the RSP-975 is in standby mode the AC outlet is also off. When the RSP-975 is fully functional, the AC outlet is live.

Remote Sensor 7

This sensor receives infrared signals from the handheld remote control. Make sure you do not accidentally block this sensor with cables or accessories.

MASTER VOLUME Control 3 29

The MASTER VOLUME knob is an electronic rotating control. Turn it clockwise to increase the volume; counterclockwise to de- crease. MASTER VOLUME buttons are also available on the RSP-975's handheld remote control.

VOLUME Display 4

As you adjust the volume, a digital display located above the con- trol will provide a volume indication in one decibel steps with +12dB being maximum output level and –67dB being minimum.

TONE Controls 18

BASS and TREBLE controls increase and decrease the audio signal’s low and high frequency content. Rotate each one clock- wise to increase output in the respective frequency range and counterclockwise to reduce it. The center detent removes each control from the audio path for maximum signal integrity.

LISTENING SOURCE Buttons 5 34

Eight large front panel LISTENING buttons allow you to select an audio or video source component such as CD, TUNER, VCR, DVD, etc. Simply push any of these buttons to select an input source.

(The handheld remote has functionally identical buttons.) You will hear this source and, if you have selected a video source, see its picture on your TV monitor. An LED indicator on each pushbutton lights to confirm your selection.

Note: As delivered from the factory, pushing one of these buttons activates the analog audio inputs for each component. However, to accommodate digital signals available from many source com- ponents (such as CD players and Dolby Digital DVD players), the RSP-975 also provides four digital inputs which may be used in- stead. See below.)

DIGITAL INPUT Button 12 40 / INPUT LEDs 15

In addition to analog audio inputs for each of eight source compo- nents, the RSP-975 provides DIGITAL INPUTS for up to four digital audio sources. These four DIGITAL INPUTS can be assigned to any of the eight LISTENING inputs

The DIGITAL INPUT button allows you select one of these digital inputs to use in place of the ANALOG INPUT for each LISTENING SOURCE SELECT button. For example, if you have a DVD player , you can connect the DVD player’s digital output to the DVD DIGI- TAL INPUT and then tell the RSP-975 to use the digital signal in place of the analog signal.

To select a DIGITAL or ANALOG input for a given LISTENING SOURCE input:

•Select the desired LISTENING SOURCE input.

•Repeatedly press the DIGITAL INPUT button to sequentially step through the available digital inputs (OPTICAL/COAX1/COAX2/DVD/ ANALOG). Stop when the desired INPUT LED lights.

NOTE: The DIGITAL or ANALOG INPUT is immediately memorized as it is selected and will be automatically activated when you se- lect that LISTENING SOURCE SELECTOR button in the future.

5.1 CH Button 13 39

This button overrides all other input selectors (both analog and digital) and directly connects an external adaptor (such as Rotel’s RDA-986 DTS Processor) to the RSP-975’s MASTER VOLUME con- trol. This allows the RSP-975 to remain the central controller for even the most advanced audio/video systems. When activated, all of the RSP-975’s inboard Dolby processing is bypassed.

SURROUND MODE LEDs 17

The RSP-975 provides three different surround sound modes to accommodate different types of audio and video source material as described below. These LEDs tell you which surround sound mode you’ve selected. Here is a brief description of the various surround modes.

STEREO is a conventional 2-speaker stereo direct bypass mode with no surround sound or other processing. The FRONT LEFT speaker, the FRONT RIGHT speaker, and the SUBWOOFER (if present) are on; all other speakers are off.

DOLBY DIGITAL provides proper playback decoding processing for any discrete 5.1 channel Dolby Digital encoded digital audio source such as an AC-3 Laser Disc or DVD disc. Dolby Digital pro- vides the highest level of surround sound performance with 5 channels of discrete surround information plus subwoofer. Dolby Digital is only available when using one of the DIGITAL inputs. It is not available for ANALOG inputs.

DOLBY PRO LOGIC provides proper playback decoding and pro- cessing for any Dolby Surround encoded analog audio source, whether it be a music CD, videotape, videodisc, conventional ste- reo TV broadcast, or satellite broadcast. Dolby Pro Logic process- ing and playback through a properly calibrated system will preserve the directionality, ambiance, and spatial effects intended by the source’s producers. Dolby Pro Logic can also provide ex- cellent surround sound playback of musical recordings.
