MMPC Model 10/20  (250-1640/41)     Using SBP-SET      Faxback Doc. # 2573

Like SBP-MIX, SBP-SET lets yo adjust the volume of audio sources, mix
sound, and choose filters.  The SBP-SET command line in the AUTOEXEC.BAT
file runs SBP-SET automatically at system startup.  Volume adjustments
that you make by changing the SBP-SET command line in AUTOEXEC.BAT are
recognized after a system restart.

SBP-SET lets you perform the following tasks:

°  select an audio sources for recording

°  Choose a filter

°  Adjust the volume for an audio source

°  Adjust the master volume

°  mix sound from different audio sources

You can also run SBP-SET for the MS-DOS prompt.  At the MS-DOS prompt,
type "SBP-SET /H" and press ENTER.  A description of each SBP-SET command
line option is displayed.  Run the program again, using the options of
your choice to adjust volume.

The default SBP-SET command line is:

 "SBP-SET /M:10 /VOC:10, 10 /CD: 10 /FM: 12, 12 /Line:10,10"

M sets the left and right channels of master volume, VOC sets the left
and right channel of voice, CD sets the volume for a CD, FM sets
synthesizer volume, and LINE sets the volume for a line audio source.

To change the volume for sources used with MS-DOS based applications
at system startup, use an editor to change the SBP-SET line of the
AUTOEXEC.BAT file in your root directory.
