This menu, which is reached from the MAIN MENU, provides sta- tus information and setup options for digital inputs.

The first two lines of the screen allow you to set system-wide configuration options for Dolby processing:

COMPRESSION: Today’s digital sources are capable of extremely high dynamic range (the difference between the softest and loud- est sounds). In some cases, the available dynamic range may tax the amplifiers or speakers. In other cases, it may be desirable to compress the dynamic range when listening at low volume levels. This configuration option allows you to select three different lev- els of dynamic range: OFF (no compression), MODERATE, or LATE NIGHT (maximum compression). The factory default is OFF (no compression). If loud passages are causing distortion or audible stress to the system, try a setting with more compression.

PRO LOGIC: This setting determines how the RSP-985 processes

2-channel Dolby Digital or DTS source material. Processing of dis- crete multi-channel surround material is automatic. But, some source material, such as a CD played on a Dolby Digital DVD or an older movie soundtrack, might have either a 2-channel stereo sig- nal or a matrix encoded two-channel Pro Logic signal. In some cases, the RSP-985 can detect an encoded ID tag which tells it how to process a 2-channel signal. In other cases, it cannot.

The options for processing 2-channel signals from a Dolby Digital or DTS source are as follows.

Auto/On: Turns on Dolby Pro Logic decoding for all signals un- less the RSP-985 is able to sense a control code identifying the 2-channel material as conventional stereo, in which case Pro Logic is turned off automatically. This is the default setting, suit- able for most applications.

Auto/Off: Turns off Dolby Pro Logic decoding and plays 2-chan- nel stereo, unless a Pro Logic signal is specifically identified, in which case Pro Logic will be activated.

On: Turns on Dolby Pro Logic decoding for all 2-channel signals, disabling the automatic sensing.

Off: Turns off Dolby Pro Logic decoding for all 2-channel sig- nals, disabling the automatic sensing. Plays conventional 2- channel stereo.

Note: The above settings only effect 2-channel signals from a Dolby Digital or DTS source. Discrete digital surround signals (e.g. 5.1 channel signals) will play correctly regardless of the setting.

The three lines in the DIGITAL AUDIO STATUS portion of the menu screen provide information about the current status of Dolby Digi- tal inputs:

INPUT: Shows the name of the input source.

SIGNAL: Shows the format of the current source, i.e. DOLBY DIGI- TAL, DTS, etc.

CHANNELS: Dolby Digital and DTS signals can contain up to six discrete channels of information – left, center, right, left rear, right rear, and a subwoofer or low frequency effects channel. This sta- tus line indicates how many channels are active in the current source material.
