Setting both of these controls to zero will disable the dynamic range control in Lineout mode. Full
dynamic range control is always applied in RF mode due to the limited bandwidth for audio in the RF
signal.
Apply RF Mode Gain
When you set the Operation Mode to RF, the Apply RF Mode Gain control is enabled. Select Yes
(default) to apply an 11 dB gain to the overall program level.
Stereo Down Mix Mode
This control sets the type of downmix to stereo, if applicable. Options are:
•
LtRt
•
LoRo
•
Auto or LoRo
•
Auto or LtRt (default)
The Left total/ Right total (LtRt) downmix is suitable for Dolby Pro Logic® or Dolby Pro Logic II decoding.
The Left only/Right only (LoRo) downmix is suitable for playback on a stereo hi‐fi or on headphones. The
two Auto selections follow the recommendation in the source stream if present, or revert to the
specified downmix if no recommendation is present.
Dual Mono Playback
The Dual Mono Playback setting applies only when decoding a dual mono program—a mode that is only
available from older encoders (not Selenio encoders). Dolby Laboratories now promotes the use of
stereo encoding, even for dual mono content. The settings for Dual Mono Playback are:
•
Stereo (reproduces both channels separately into the Left and Right channels of a stereo signal)
•
Left Mono (reproduces channel 1 as mono in the Left channel of a stereo signal)
•
Right Mono (reproduces channel 2 as mono in the Left channel of a stereo signal)
•
Mixed Mono (mixes channels 1 and 2 to mono; this is rarely a good choice since the two channels are
theoretically independent sources of audio)
Status Audio x
The following read‐only parameters are in this section:
•
Present (reports the presence of audio stream)
•
Decode Errors
•
Standard (reports the presence of the following audio compression standards:
•
Unknown
•
