DIGITAL SURROUND SOUND PROCESSOR RSP-975
8
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.)

/ INPUT LEDs

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.
