Input Gain and Output Volume Control:
UPDATE GAINS-PHASE: CMD=01H
A. The User has to send the following Command, including the value to be assigned to “Vol”, for modifying
the Input Gain (Chn = 0, 1, 8) or the Output Volume (Chn = 2, 3, 4, 5, 6, 7).
Also the Output signal Phase can be modified:
TX:
XX = 0,..,31 ( ID device )
Chn = 0,...,8: Channel selected , 0, 1, 8= In 1, In 2, In 3; 2,...,7= Out 1,.., Out 6; when Channel 0, 1, 8
selected, then
Vol
= Input Gain , when Channel 2, 3, 4, 5, 6, 7 selected, then Vol = Output Vol .
Phs = Phase only if the Chn >1; Value =0, 1 where 0= direct , 1= inverse (180')
Vol = Gains from 0 to 180 (-12 dB / +6 dB step 0.1 dB )
B. If the command has been properly executed and the Gain/Volume modified, then the microcontroller will
send back to the User (eg Crestron/AMX Remote Control..) the same frame used by the command:
