Instruction Manual – BCS Basic Control Structure Protocol
Absolute Method
The Absolute Method adjusts digital input gain
to
a specific decibel level.
To adjust digital input gain to a specific decibel level:
1.
Enter the Absolute command below. Replace the “
#
”s with the level and input number(s) and
replace the “
^^^
” with the decibel level (entered as a decimal number; see “General Rules for
Audio” on page 12).
CL#I#VA^^^T
2.
Repeat Step 1 as necessary for additional sources (inputs) that will be routed to the same destination
(output).
Digital Input Gain Absolute Examples
Note:
If the input gain adjustment requested results in an overall decibel level outside of the range
(above or below) for the specific type of audio board that has been selected for adjustment, the
system will respond with an “
X
” indicating an invalid value was entered. For a specific audio board’s
input gain adjustment range, see the specific board’s documentation.
Relative Method
The Relative Method adjusts digital input gain
by
a specific decibel amount.
To adjust digital input gain by a specific decibel amount:
1.
Enter the Relative command below. Replace the “
#
”s with the level and input number(s) and
replace the “
^^^
” with the decibel level (entered as a decimal number; see “General Rules for
Audio” on page 12).
CL#I#VR^^^T
2.
Repeat Step 1 as necessary for additional sources (inputs) that will be routed to the same destination
(output).
Digital Input Gain Relative Examples
Note:
If the input gain adjustment requested results in an overall decibel level outside of the range
(above or below) for the specific type of audio board that has been selected for adjustment, the
system will respond with an “

” indicating an invalid value was entered. For a specific audio board’s
input gain adjustment range, see the specific board’s documentation.
