Speaker Attenuator
Due to practical aspects the steps in the speak-
erattenuators are not linear over the full range. At
attenuations more than 24dB the steps increase
from 1.5dB to 10dB (see data byte specification).
Subwoofer
The Subwoofer output is a differential mono out-
put with 6dB gain. The outgoing signal generated

by adding the left and the right channel. The at-
tenuator is exactely the same like the other
speakers.
In some applications it could be helpful to change
the phase of this output by software. For this pur-
pose a bit is available in the subwoofer byte to
change the phase from 0° to 180°.
