Adjusting Speech and Program Audio Levels
The volume levels of the Speech and Program Audio signals at the line-level outputs
can be adjusted on the MD7x2’s front panel. The volume levels of the Speech and
Audio Program can be adjusted individually or simultaneously for each output
channel.
Before making any volume adjustments, the volume controls must be set to adjust
the desired parameter. Repeatedly press the
SELECT
button to toggle between the
four adjustment modes: Speech, Program Audio, or Program Audio. When
the
SPEECH
LED is illuminated, any changes in volume will be made to the Speech
portion of the audio signal. When the
PGM
LED is illuminated, any changes in
volume will be made to the Program Audio portion of the audio signal. When the
SPEECH
and
PGM
LEDs are illuminated, any changes in volume will be made to
the Speech and Program Audio portions of the audio signal. When neither of the
LEDs are illuminated, the volume adjustment buttons will not function.
NOTE:
Depending on the mixer setting of the MD7x2, the actual volume that is
adjusted can be varied.
For example, if the program audio output contains program audio and speech
components, then raising the program output volume will raise the volume of both
components simultaneously.
