loudness OFF (1)
For example to select -17.5dB loudness the Data Byte is: XXX01110
Note (1):
If the loudness is switched OFF, the loudness stage is acting like a volume attenuator with flat frequency response. D0 to D3 determine the
attenuation level
An additional direct mute function is included in the Speaker Attenuators
(*) BIT D4 = 1disables the zero cross mute and pause detector, otherwise always active
