DIGITAL SURROUND SOUND PROCESSOR RSP-975

Programming the RR-939

The RR-939 is preprogrammed from the factory to operate the RSP-975. Should the AUDIO command set on your RR-939 not op- erate the RSP-975, it’s possible that the programming had been in- advertently changed. To reprogram the remote to operate the RSP-975:

1.Press the AUDIO button at the top of the remote while simulta- neously pressing the MUTE button and hold both for at least one second. The AUDIO button will light in red for 20 seconds, indicat- ing that you have entered the program mode. The next step must be done within this 20 second period, or the RR-939 will revert to its standard operating mode.

2.Use the NUMERIC buttons to enter the 3-digit code (001) for the RSP-975 – press 0, then 0, then 1. The AUDIO button will flash each time you enter a digit.

3.Store the code number by pressing the corresponding AUDIO button again. The button will blink twice to confirm the storage of the code in memory.

POWER Switch 30

Duplicates the function of the Standby Switch on the front panel. Press to activate the RSP-975. Press again to deactivate.

MASTER VOLUME Controls 29

A pair of buttons which duplicate the function of the front panel volume control. Press VOLUME DOWN to reduce the volume and press VOLUME UP to increase the volume.

The VOLUME UP/DOWN buttons are also used in making certain system configuration settings.

SELECTOR Buttons 34

A group of ten buttons which duplicate the function of the LIS- TENING SOURCE SELECTOR buttons on the RSP-975 front panel. Select any input source by pressing the appropriate button.

The labels on the remote buttons match the front panel buttons, except that the button labelled PHONO/LD corresponds to the front panel DVD input button and the button labelled AUX 1 corre- sponds to the front panel AUX input button. The remote buttons la- belled AUX 2 and TAPE 2 are not used with the RSP-975.

5.1 Button 39

Duplicates the 5.1 CH button on the front panel. Selects the 5.1 Channel input, overriding any other sources.

MUTE Button (remote only) 31

Push this button once to reduce the output levels to zero – to turn the sound off. The front panel MUTE LED will light. Press the MUTE button again to restore the prior volume level.

SELECT Button (Digital Input) 40

Duplicates the DIGITAL INPUT button on the front panel. Selects the ANALOG input or one of the DIGITAL inputs for the currently selected source.

SURROUND + Button 32

Duplicates the function of the front-panel SURROUND MODE but- ton. Steps sequentially through various surround sound operating modes. Your current selection will be indicated by front panel LEDs and will be memorized for ANALOG inputs.

SURROUND DELAY Button (remote only) 38

The surround processing in the RSP-975 delays the signal sent to the rear surround speakers as a means of simulating a larger physical space (such as a movie theater or concert hall) and to ensure that sounds from the front speakers reach your ear first. The SURROUND DELAY button steps sequentially through four available settings for your selected surround mode (not applicable in STEREO modes).

NOTE: The SURROUND DELAY setting is system-wide. Changing it will increase or decrease the relative delay time for all inputs and both surround modes. The setting is automatically memorized as it is made.

You will get visual confirmation of your delay time setting on the VOLUME DISPLAY as you adjust the setting. The delay time setting also appears in the ON-SCREEN DISPLAY (see below).

There are no hard and fast rules for setting proper delay times. Many listeners will be satisfied with the default settings. Others will want to experiment. In the end, it is a matter of personal taste.

In general, longer delay time settings will tend to create the illu- sion of a larger acoustic space, although if overdone, the effect can be exaggerated and unnatural. Longer delay settings may typically be more spectacular. Shorter delay times may be more natural.

Delay times also may need to be adjusted depending on the rela- tive distance from the listening position to the front and rear speakers. As a general rule, your attention should never be drawn to the surround speakers as a primary sound source, particularly when listening to music. If you are closer to the rear speakers, in- creasing the delay time may prevent this problem.

The four DELAY TIME choices for each surround mode are:

	STEP 1	STEP 2	STEP 3	STEP 4
STEREO:	NONE	NONE	NONE	NONE
DOLBY PRO LOGIC:	15 ms	20 ms	25 ms	30 ms
DOLBY DIGITAL:	NONE	5 ms	10 ms	15 ms

Again, experimentation will show you which settings are best for your source material, room conditions, and system setup.
