Dynamic Range Compression Control

(Only with Dolby Digital and DTS source formats that have a Dynamic Range Compression
flag)

This control adjusts the gain applied to Dolby Digital or DTS listening modes to compress the
signal outputs during the decoding process. The three possible settings are None, Minimum,
and Maximum. The default setting is None.

Off —

The signal is uncompressed and is played with the full original dynamic range.

Minimum —

The audio is partially compressed. In this mode, the volume of the loudest

passages is reduced but quieter passages are kept at their original level. This level is
recommended for normal listening.

Maximum —

The audio is fully compressed. This level is recommended for environments

where loud audio is not permitted.

NOTE:

DTS source formats have only two states (On and Off) for dynamic range

compression. Therefore, Minimum and Maximum both apply the same dynamic
range compression.
