24. [ +O ]
This command increases the output volume level by 1 up to the
maximum level of 32. If the command is sent after a level of 32 has
been reached, it will have no effect on the output.
Command Format: [+OCn]
Cn = Card ID (n = # from 1 to max slots)
Example:
Increase the output volume of C4 (slot 4) from 31 to 32 by sending the
command [+OC4].
25. [ -O ]
This command is the same as [+O] except that it decreases the output
volume level by 1 down to a minimum level of 1.
26. [ +I ]
This command increases an input level by 1 up to the maximum of 32.
Attempts to increase the level after reaching 32 have no effect.
Command Format: [+ImCn]
m = Input No. (m - # from 1 to 8)
Cn = Card ID (n = # from 1 to max slots)
Example:
Increase the input level of Input 2 on C4 from 31 to 32 by sending the
command [+I2C4].
27. [ -I ]
This command is the same as [+Im] except that it decreases an input
level by 1 down to the minimum level of 1.
28. [VLO]
This command sets the absolute output volume to a specific value.
Command Format: [VLOAvCn]
v = Volume Level (# from 01 to 32)
Cn = Card ID (n = # from 1 to max slots)
Example 1:
Set the output volume level to a level of 16 using the command
[VLOA16C4].
29. [VLI]
This command sets an input level to a specific gain value.
Command Format: [VLImAvCn]
m = Input (m = # from 1-8)
v = Gain level (v = # from 01 to 32)
Cn = Card ID
Example 1:
Set the input gain level for Input 4 to a value of 24 using the command
[VLI4A24C4].
Volume Ramping Commands
The following commands are used to control the volume of the
MT109-100. They may be used with computer control, or with the
{SETVK} command using keys on the front panel. The following code
sample sets front panel keys 8 and 10 to Ramp Up and Ramp Down
respectively. See your Front Panel User’s Guide for more details.
When defined as a volume control key, the key will respond to two
conditions: press and release. Below is an example of how to use the
ramping feature. Subroutine 8 starts ramping up when key 8 is pressed and
subroutine 10 starts ramping down when key 10 is pressed. Subroutine 108
stops ramping when either key is released.
{WRS8=RUPC4} //Ramp Up
{WRK8=8,108,0,0,0} //Press= start, release= stop
{WRS10=RDNC4} //Ramp Down
{WRK10=10,108,0,0,0} //Press= start, release= stop
{WRS108=RSTC4} //Stop Ramping
{SETVK8} //Set key 8 as volume key
{WRLK8=VOL_UP} //Define Key 8 Label
{SETVK10} //Set key 8 as volume key
{WRLK10=VOL_DN} //Define Key 8 Label
[RAMP=10C4] //Set the ramp rate.
30. [RUP]
This command ramps the output volume to its maximum level at the
rate defined using the [RAMP] command.
Command Format: [RUPCn]
Cn = Card ID (n = # from 1 to max slots)
Example:
Ramp the output volume from a starting level of 10 to the maximum
level of 32 for the card in slot 4. Send the command [RUPC4] and the
system will respond with the following feedback:
[11][12][13][14]…[32]
31. [RUP=]
This command ramps the output volume to a user defined level at a
rate defined using the [RAMP] command.
Command Format: [RUP=xxCn]
xx = Stop Level (xx = # from 01-32)
Cn = Card ID (n = # from 1 to max slots)
Example:
Ramp the output volume from a starting level of 1 to a level of 20 for
the card in slot 4. Send the command [RUP=20C4] and the system will
respond with the following feedback:
[02][03][04]…[20]
