All input volume:

= 0 dB.
Gain/volume adjustment note:
All front panel gain/volume adjustments are in
0.5 dB
increments whenever the knobs are turned
slowly
. However
, the SIS messages (RS-232) that the MVC sends to the host ar
e in
1 dB
increments
only
. The MVC treats each 0.5 dB gain/volume increment between two consecutive
whole dB units as the lower of the two units. As shown in the table examples, in a continuous
adjustment sequence, the SIS messages to the host will send the same value twice.
