Table 91. FADER - data byte 14h bit description
Bit Symbol Description
7 and 6 FADM[1:0] fader mode; enable fader control for front or rear
00 = no fader; front output = 0 dB; rear output = 0 dB
01 = rear fader; front output = 0 dB; rear output = FAD[5:0]
10 = front fader; front output = FAD[5:0]; rear output = 0 dB
11 = output volume; front output = FAD[5:0]; rear output = FAD[5:0]
5 to 0 FAD[5:0] Fader attenuation setting; 00 0000 to 11 1111 = −1 dB to −64 dB. For
output mute control see data byte 15h; OUTPUT (see
Table 92).
