The User has to send the following Command
,
including the value to be assigned to
“
Vol
”,
for
modifying the Input Gain
(
Chn
= 0, 1)
or the Output Volume
(
Chn
= 2, 3, 4, 5, 6, 7).
Also the Output signal Phase can be modified

If the command has been properly executed and the Gain

then the
microcontroller will send back to the User
