Setting the Breakaway Option
To set the Breakaway option:
Press either the AUDIO (for audio control only) or the VIDEO (for video
control only) button:
If the AUDIO button illuminates, switching operations relate to Audio,

and the 7-segment display shows the video status
7.8 The Audio Output Gain Control
The audio output signal gain is activated when the machine is in the AUDIO
or AFV mode.
To increase or decrease the audio gain:
1. Select the output whose audio gain you want to change.
For example, press OUT 4.
The OUT 4 button blinks and so does the respective input on the display.
2. Press the + or – button to increase or decrease, respectively, the audio gain of
the selected output.
The audio gain display lights and the audio level value shows on the display.
The
VP8x8A
output audio signal level
1
is shown on the REL. AUDIO
LEVEL 7-segment display.
The factory default audio gain is set to 0dB. An audio gain value of 0dB
indicates that the output signal value is identical to the input signal value.
When increasing/decreasing the audio gain, the output signal level is
higher/lower than the input signal level.
Gain level values are relative since the audio input signal can be adjusted via
the trimmers on the rear panel, while the range of the output gain remains
constant
1
, independent of the input level adjustment. When decreasing the
audio level below the minimum display value, the 7-segment display shows
L, indicating low audio value (see Figure 26, the output gain vs gain value
graph).
1 Minimum level is -19, and maximum level is +16
