7.4.5. Audio Channels Processing (-A4 and –AES only)
There are 4 menu items to adjust the routing and processing of the audio outputs. For simplicity only the
menu for channel 1 will be shown in the manual.

CONFIGURING THE VIDEO AND SOURCE ID CONTROLS

The Video/SID menus are used to configure parameters associated with the video processing functions
and the VBI decoders. The chart below shows the items available in the Video/SID menu. Sections 7.5.1
to 7.5.20 give detailed information about each of the parameters.
Gray background indicate un-implemented or un-tested features
Basic audio channel manipulation is possible with this control.
Any input channel can be routed to any output channel. A mono mix of either L/R
input pair can also be performed. Muting an output is also possible.
Warning: This processing takes place before going to the audio analysis and
bargraph display section. This means that you will be monitoring the processed
version of the audio and not the input audio.
The channel output level (-A4 only) is adjusted with this control. It has a range
of approximately 12 dB with 1/10 dB resolution. The displayed value is the
analog output level (dBu) corresponding to a 0dB FS digital input signal.
This control will adjust the level of channel 1. It has a range of +/-12 dB with
1/10 dB resolution. The displayed value is the amount of gain (+ve), or
attenuation (-ve), in decibels, where 0dB corresponds to unity gain.
Warning: Whenever +ve gain is configured, there is the possibility of distortion
due to clipping. If the input audio level is increased to greater than 0dB FS, by
adding gain, then the output audio will be limited at 0dB FS.
Warning: This processing takes place before going to the audio analysis and
bargraph display section. This means that you will be monitoring the processed
version of the audio and not the input audio.
