aa = Input1 Lock Status
bb = Input2 Lock Status
where 01 = locked and 00 = unlocked
cc = Sync Flash
where 01 = Flashing and 00 = Not flashing
dd = Input Gain For INPUT 1
where dd is a hex value representing the current gain
on this INPUT between:
00 = Mute -> FE = 0dBFs
ee = Input Gain For INPUT 2
where ee is a hex value representing the current gain
on this INPUT between:
00 = Mute -> FE = 0dBFs
ff = Input Gain For INPUT 3
where ff is a hex value representing the current gain
on this INPUT between:
00 = Mute -> FE = 0dBFs
gg = Input Gain For INPUT 4
where gg is a hex value representing the current gain
on this INPUT between:
00 = Mute -> FE = 0dBFs
hi = Output Gain For All OUTPUTS
i is a hex value representing the current gain on outputs 1
and 2 summed and h is a hex value representing the current
gain on outputs 3 and 4 summed where:
INPUT 1/3
0x00 = 0dB
0x01 = +3dB
0x02 = +6 dB
0x03 = +12 dB
INPUT 2/4
0x00 = 0dB
0x04 = +3dB
0x08 = +6dB
0x0C =+12dB
For example, if INPUT 1 and 2 are set to 3 dB gain and input 3 and 4 are set to
12 dB gain then:
h = 0x03 + 0x0C = 0x0F
i = 0x01 + 0x04 = 0x05
