The total through-system gain (the amount of input gain plus the amount of
output gain) for any input to output routing path will not 10 dB
(automatically limited by the router). If a volume command is entered that
e10 dB when it is combined with the gain of an input, the command
will be accepted (and will be indicated in status results) but will not result in
an audible difference of more than +10 dB.
6.1 Adjusting Volume
To adjust volume use any of the following three methods:
ä
Absolute – adjusts the volume
to
a specific decibel level
ä
Relative – increases/decreases the volume
by
a specific decibel amount
ä
Increment/Decrement – increases or decreases the volume a step
Absolute Method
The Absolute Method adjusts the volume of an output
to
a specific decibel level.
To adjust an output’s volume to a specific level,
enter the Volume Absolute
command below. Replace the “
#
”s with the level and output number(s) and
replace the “
^^^
” with the decibel level (entered as a decimal number; see
page 6-1).

Volume Absolute Examples:
BCS Command
Action
CL0O98VA100T
Adjusts volume to 10.0 dB for Output 98 on Level 0
CL0O156 157VA-700T
Adjusts volume to -70.0 dB for Outputs 156 and 157 on Level 0
Note:
If the decibel level requested is outside the range for the selected output,
the system will respond with an “
X
” indicating an invalid value was entered
(for a specific audio board’s volume adjustment range, see the
Boards & Specifications
section of this manual ).
Relative Method
The Relative Method adjusts the volume of an output
by
a specific decibel
amount.
To adjust an output’s volume by a specific level,
enter the Volume Relative
command below. Replace the “
#
”s with the level and output number(s) and
replace the “
^^^
” with the decibel level (entered as a decimal number; see
page 6-1).
