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).
