Audio Decoder - Line Mode Adjust; Audio Decoder - Routing - Ericsson RX8000 Reference Manual

Using the Equipment
This field specifies the Dynamic Range Control (DRC, or Operational Mode) for a
specific Audio Decoder. Dynamic Range Control can be used to automatically adjust
the audio output signal level according to the audio's dynamic range. This is
dependent on how the audio is configured during the encode stage.

3.14.4.4.7 Audio Decoder > Line Mode Adjust
This field specifies the Line Mode adjust for a specific Audio Decoder. This
weighting value affects the Dynamic Range Scale Factor. This is only applicable if
the Dynamic Range Control is set to LINE MODE.

•
3.14.4.4.8 Audio Decoder > Routing
This field specifies the routing for the audio signal for a specific Audio Decoder.

OFF – Disables any adjustment to the audio signal level that would be applied
according to the audio's dynamic range. The audio output level will be the same
as the audio input level.
LINE MODE – In this mode, the Line Mode dynamic range compression variable
is applied according to the Line Mode compression profile in the Dolby
Metadata. The volume of loud sounds is reduced or quiet sounds are amplified
according to the audio's dynamic range. The amount of dynamic range
compression applied to the audio output can be made variable according to the
Line Mode Adjust setting.
RF MODE – In this mode, the RF Mode dynamic range compression variable is
applied according to the RF Mode compression profile in the Dolby Metadata.
An 11 dB gain is applied to the output signal. RF Mode is optimized for linear
signal transmission (i.e. not digital transmission), the output can be attenuated
by 11 dB and applied to the input of a linear modulator without causing over
modulation and consequent distortion.
OFF – A zero scaling factor is applied to the audio output when the Dynamic
Range Control is set to LINE MODE. Effectively the audio output level will be the
same as the audio input level.
LOW – A mid-range scaling factor of 0.5/0.5 (high/low) is applied to the audio
output when the Dynamic Range Control is set to LINE MODE. Effectively the
audio output level will be different to the audio input level.
HIGH – A maximum scaling factor of 1.0/1.0 (high/low) is applied to the audio
output when the Dynamic Range Control is set to LINE MODE. Effectively the
audio output level will be different to the audio input level.
STEREO – Channel 1 will be output on the left, channel 2 will output on the
right.
