Specifications

Examples:
BCS Command Action
CL0O2VMT
Mutes volume for Level 0,
destination 2
CL0O1 4VMT
Mutes volume for Level 0,
Destinations 1 and 4
To remove the mute, enter the command using
the following command line format (where “#”
represents any valid audio level or destination
number).
CL#O#VUT
Tip: This command is easy to remember if you
think of the “VU” as “volume un-mute.”
Examples:
BCS Command Action
CL0O3VUT
Removes mute for Level
0, destination 3
CL0O6 7VUT
Removes mute for Level
0, destinations 6 and 7
Note: When a Mute command is followed by
any other volume command, other than un-mute,
the volume returns to its previous un-muted
state before the new command is applied. For
example, if destination 1 was set at 5 dB and a
mute command was entered (CL0O1VMT), and
then later an Increment command
(CL0O1VS+T) was entered, the result would be
a volume level of 5.5 dB.
CHECKING VOLUME STATUS
You can check volume status only from an
external controller via BCS commands.
To check the volume status for a specific
destination, enter the command using the
following command line format (where “#”
represents any valid audio level or destination
number). The decibel level in the result of the
status check is specified as a decimal number to
the tenth place without the decimal marker; for
example if the result is –480, the decibel level is
–48.0 or if the result is 48, the decibel level is
+4.8.
SL#O#VAT
To cancel an incomplete BCS command, enter
the “X” command at any time.
Examples:
Note: You cannot enter multiple levels or
destinations in Volume Status commands.
