Adjusting and Verifying Audio
18
Instruction Manual – BCS Basic Control Structure Protocol
Increment/Decrement Method
The Increment/Decrement Method increases or decreases digital input gain by a step.
To adjust digital input gain up a step:
1.
Enter the Increment command below. Replace the “
#
”s with the level and input number.
CL#I#VS+T
2.
Repeat Step 1 as necessary for additional sources (inputs) that will be routed to the same destination
(output).
To adjust digital input gain down a step:
1.
Enter the Decrement command below. Replace the “
#
”s with the level and input number.
CL#I#VS-T
2.
Repeat Step 1 as necessary for additional sources (inputs) that will be routed to the same destination
(output).
Digital Input Gain Increment and Decrement 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.
Verifying Digital Input Gain Status
The digital input gain setting will display in parentheses ( ), even if the input is not receiving a signal.
The decibel amount in the result is specified as a decimal number to the tenth place without the decimal
point. For example, if the result is -480, the decibel level is at -48 or if the result is 65, the decibel level
is at 6.5.
To verify digital input gain status:
1.
Enter the Verify Status command below. Replace the “
#
”s with the level and input number.
SL#I#VT
