Meter Output Adjustments
WARNING
The D/ESAM system has been completely aligned to the meters. Any adjustment
to the meter outputs without first precisely following the system alignment
procedure can cause system level problems.
Meter outputs are factory set for 20dB below digital clipping or +8dBu (analog
meters only) when reading 0VU (-8PPM). This level should not be changed unless
internal system reference level is changed. Analog Program and Monitor output
levels can be set independent of Meter reference level.
The location of the Meter output gain trims are indicated in the figure above. Note
that the gain trims are covered to prevent accidental adjustments.
NOTE
The internal tone generator can be used for alignment. In Chapter 5, see the
“Alignment - Menu 6.1” section for setting tone generator options.
Program Output Adjustments
The following procedure is specific to the analog Program output only and assumes
that meters are aligned correctly.
1.
Assign a source with reference tone to all four D/ESAM Program buses.
In Chapter 3, refer to the “Channel Assignment” section for
instructions on Channel Assignment and the “Manual Program /
Preset Configuration” section for details on Program / Preset
Configuration.
2.
Bring up the fader(s) so that meters read 0VU (-8PPM).
3.
Adjust each of the Program output gain trims to the reference level.
The location of the Program trims are indicated in the figure above.
NOTE
The internal tone generator can be used for alignment. In Chapter 5, see the
“Alignment - Menu 6.1” section for setting tone generator options.
