LOD1, Clr, Volume Ramping Feature, Rup, RUP=xx

MULTI-TASKER™

19.[LOD1]

This command enables the loudness feature.

Command Format: [LOD1CnUi]

Cn = Card ID (n = slot # from 1 to max slots)

Ui = Unit ID (i = # from 0 to 9)

Example:

Turn ON the Loudness feature of the MT109-102in slot #4 by sending the command [LOD1C4].

20.[CLR]

This command clears the card and resets it to its factory defaults. All volume levels are set to maximum, bass and treble are set to midrange, loudness is turned off and mute is turned off.

Command Format: [CLRCnUi]

Cn = Card ID (n = slot # from 1 to max slots)

Ui = Unit ID (i = # from 0 to 9)

Example:

Clear the MT109-102in slot #4 by sending the command [CLRC4]. Send the status command after the clear command and receive the following feedback:

In1Vol=16/16

In2Vol=16/16

In3Vol=16/16

OutVol=16/16

Bass =08/16

Treble=08/16

Loudness:OFF

VOLUME RAMPING FEATURE

The following 7 commands are used to control the output volume of the MT109-102. They may be used with computer control, but also are designed to be used 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, 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.

21.[RUP]

This command ramps the OUTPUT volume to its maximum level at the rate defined using the [RAMP] command.

Command Format: [RUPCnUi]

Cn = Card ID (n = # from 1 to max slots)

Ui = Unit ID (i = # from 0 to 9)

Example:

Ramp the output volume from a starting level of 10 to the maximum level of 16 for the card in slot #8. Send the command [RUPC8] and the system will respond with the following feedback:

[11][12][13]…[16]

22.[RUP=xx]

This command ramps the OUTPUT volume to a user defined level at a rate defined using the [RAMP] command.

Command Format: [RUP=xxCnUi]

xx= Stop Level (xx = # from 01-16)

Cn = Card ID (n = # from 1 to max slots)

Ui = Unit ID (i = # from 0 to 9)
