Audio input gain and attenuation
N
The set gain (G) and set attenuation (g) commands are case sensitive. The increment and view commands are not case
sensitive.
N
You can set the input level to whole dB values only, using the
X$
*
X%
G or
X$
*
X&
g command. The increment and
decrement level (
X$
+G and
X$
-G) commands increase and decrease the level in steps of 0.5 dB only. The
X^
values for
all audio gain and attenuation commands are reported in whole dB levels only; the reported
X^
value is rounded up to
the next higher magnitude value (for example, +1.5 dB is reported as +2 dB and -3.5 dB is reported as -4 dB).
