Audio SEND_COMMANDs (Cont.)
AUDOUT_STEREO
Enables or disables audio
amp output in stereo
Syntax:
SEND_COMMAND <device>, "'AUDOUT_STEREO-<setting>'"
Variables:
setting = Stereo setting, either "ENABLE" or "DISABLE"
Example:
SEND_COMMAND dxDev,"'AUDOUT_STEREO-ENABLE'"
?AUDOUT_TESTTONE
Requests the frequency of
the test tone for the audio
port.
Requests the current frequency of test tone for the audio port addressed by the
D:P:S.
Syntax:
SEND_COMMAND <DEV>, "'?AUDOUT_TESTTONE'"
Example:
SEND_COMMAND AUDIO_OUTPUT_1, "'?AUDOUT_TESTTONE'"
Returns a COMMAND string of the form: AUDOUT_TESTTONE-<frequency>.
AUDOUT_TESTTONE
Sets the frequency of a test
tone for the audio port.
Sets the frequency, if any, of a test tone for the audio port addressed by the
D:P:S.
Syntax:
SEND_COMMAND <DEV>, "'AUDOUT_TESTTONE-<frequency>'"
Variable:
frequency = off, 60Hz, 250Hz, 400Hz, 1KHz, 3KHz, 5KHz, 10KHz, PINK
NOISE, WHITE NOISE
Example:
SEND_COMMAND AUDIO_OUTPUT_1, "'AUDOUT_TESTTONE-250Hz'"
Sets a test tone of 250Hz to play for the audio output port (#1 based on D:P:S).
?AUDOUT_VOLUME
Request the volume setting
of the specified audio output
port.
Requests the volume setting of the audio output port addressed by the D:P:S.
Syntax:
SEND_COMMAND <DEV>, "'?AUDOUT_VOLUME'"
Example:
SEND_COMMAND AUDOUT_VOLUME_1, "'?AUDOUT_VOLUME'"
Returns a COMMAND string of the form: AUDOUT_VOLUME-<value>.
AUDOUT_VOLUME
Sets the volume on the
specified audio output.
Sets the volume on the audio output addressed by the D:P:S to <value>.
Syntax:
SEND_COMMAND <DEV>, "'AUDOUT_VOLUME-<VALUE>'"
Variable:
value = 0..100
Example:
SEND_COMMAND AUDOUT_VOLUME_1, "'AUDOUT_VOLUME-50'"
Sets the volume of audio output port #1 to 50.
Note: Volume attenuation on the DVX-2150, 2155, 3150 & 3155 is not set by
percentage, like it was on earlier DVX models: On the 215x and 315x, the
output volume slider changes .5dB per click, to provide a more subtle
adjustment.
Unity gain is at 88, so a setting of 100 is actually 6dB gain. A setting of 20 would
be -34 reduction (88-20=68 clicks. @ .5dB per click =34 dB). This is only the
output slider.
See Appendix C - Volume Attenuation Table on page 123.
