RT-20 Universal Disc Player Setup
3-17

DTS DOWN MIX

Select Stereo to specify stereo downmixing as the type of DTS
downmixing to be performed. Select Lt/Rt to specify that a DTS
multi-channel input is to be downmixed into a format compatible
with the Dolby Surround matrix format. The Lt/Rt option may be
selected for surround sound when the RT-20 is connected to a
Dolby Surround compatible amplifier.
Note:
• When DTS Digital Out has been set to PCM, all digital output will be
automatically set to stereo output no matter what DTS downmix set-
ting has been specified.
• When either the Audio Out parameter 2 Channel or 5.1 Channel set-
ting is selected, the DTS multi-channels’ downmix method can be
selected.

AUDIO DRC

Controls the Dynamic Range of Dolby Digital-encoded sources.
When On is selected, the RT-20 reduces the dynamic range of high-
level peaks. As a result, low-level sounds become more audible.
When Off is selected, the RT-20 maintains the original dynamic
range of low- and high-level sounds.
Note:
This parameter is only effective with Dolby Digital encoded DVDs. Its
effectiveness varies depending on the loaded disc, the speaker configu-
ration and associated component settings.

SUPER AUDIO CD PLAY

The original format of SACDs is Direct Stream Digital (DSD). The
default setting is DSD. Select PCM to convert DSD signals to PCM.
When PCM is selected, adjustable size, distance and gain level set-
ting parameters are active. When DSD is selected, adjustable size
and gain level setting parameters are active.
