1.9 Speaker Attenuator

Due to practical aspects the steps in the speaker-attenuators are not linear over the full range. At attenuations

more than 24dB the steps increase from 1.5dB to 10dB (please see data byte specification).

1.10 Subwoofer Attenuator

The Subwoofer output is a single ended stereo output. The attenuator is exactly the same like the other speak-

ers.
