Description
The mixer utility allows you to control
audio input and output parameters:
-
choice of input and output channels
-
input and output volume levels
-
equalization (bass and treble) levels
-
stereo balance
-
channel mixing
It is used with audio playback and record programs, such as
scosound(X1),
vplay(1),
and
vrec(1).
An audio adapter must be configured on the system before
mixer can be run.
Options
The +rec | -rec option adds or subtracts recording
devices from a list of input sources. Multiple input devices
can be selected but only one of each device type. Acceptable
device names are: synth, line,
mic, cd.
The remaining options control signal levels on the specified
devices. The signal level value is represented
as n:n, which indicates the relative value of left and
right channels on a scale of 100. Entering mixer
option with no value displays the current setting.
