Audio Switching Boards: SEND_COMMANDs
IMPORTANT:
The SEND_COMMANDs listed in this section apply to all inputs and outputs when Audio Switching Boards (ASB
and ASB-DAN) are installed. The output must be in SWITCHED audio mode for these commands to function. For additional
information on NetLinx commands used in conjunction with this product, see the "WebConsole & Programming Guide –
NX-Series Controllers" (available at www.amx.com).
NOTE:
This section does not apply to Audio Insert/Extract Boards.
Note the following port information:
Commands derive their port addressing from the target D:P:S (Device:Port:System).
ASB Commands can be sent to any input/output, but are only available when Audio Switching Boards are present
in the system (and connected via an HSSI connector for Enova DGX 800, 1600, and 3200 systems).
For each system, one port is available as an additional input for down-mix. The down-mix port number follows
sequentially after the last audio only port (e.g., an Enova DGX 800 Switcher’s down-mix port is port number 17).
Audio Switching Boards signal routing is accomplished either via SEND_COMMANDs (see below) or via the System
Configuration interface (see page 127).
NOTE:
All text is based on a Unicode index.
Audio Input SEND_COMMANDs
Command
Description
?AUDIN_COMPRESSION
Requests the compression setting for the audio port addressed by the D:P:S.
Syntax:
SEND_COMMAND <DEV>, "'?AUDIN_COMPRESSION'"
Example:
SEND_COMMAND AUDIO_INPUT_1, "'?AUDIN_COMPRESSION'"
Returns a COMMAND string of the form:
AUDIN_COMPRESSION-<setting>
Note: See the AUDIN_COMPRESSION command for the list of settings.
AUDIN_COMPRESSION
Sets the compression for the audio port addressed by the D:P:S.
Syntax:
SEND_COMMAND <DEV>, "'AUDIN_COMPRESSION-<setting>'"
Variable:
• setting = off, low, medium, high, custom
Example:
SEND_COMMAND AUDIO_INPUT_1, "'AUDIN_COMPRESSION-high'"
Sets the compression setting of the audio input port #1 to high.
?AUDIN_COMPRESSION_ATTACK
Requests the compression attack for the audio port.
Syntax:
SEND_COMMAND <DEV>, "'?AUDIN_COMPRESSION_ATTACK'"
Example:
SEND_COMMAND AUDIO_1, "'?AUDIN_COMPRESSION_ATTACK'"
Returns a COMMAND string of the form:
AUDIN_COMPRESSION_ATTACK-<attack>
Note: See the AUDIN_COMPRESSION_ATTACK command for the attack range.
AUDIN_COMPRESSION_ATTACK
Sets the duration of the attack phase while compressing for the audio port addressed by the D:P:S.
Syntax:
SEND_COMMAND <DEV>, "'AUDIN_COMPRESSION_ATTACK-<attack>'"
Variable:
• attack = 1 to 2000
Example:
SEND_COMMAND AUDIO_INPUT_1, "'AUDIN_COMPRESSION_ATTACK-200'"
Sets the compression attack for the audio port to 200.
?AUDIN_COMPRESSION_RATIO
Requests the compression ratio for the audio port.
Syntax:
SEND_COMMAND <DEV>, "'?AUDIN_COMPRESSION_RATIO'"
Example:
SEND_COMMAND AUDIO_INPUT_1, "'?AUDIN_COMPRESSION_RATIO'"
Returns a COMMAND string of the form:
AUDIN_COMPRESSION_RATIO-<ratio>
See the AUDIN_COMPRESSION_RATIO command for the compression ratio range.
AUDIN_COMPRESSION_RATIO
Sets the compression ratio for the audio input port addressed by the D:P:S.
Syntax:
SEND_COMMAND <DEV>, "'AUDIN_COMPRESSION_RATIO-<ratio>'"
Variable:
• ratio = 1 to 20
Example:
SEND_COMMAND AUDIO_INPUT_1, "'AUDIN_COMPRESSION_RATIO-5'"
