Speaker attenuator
The four speakers have independent soft step speaker controls. And their attenuators can
be adjusted from +15dB to -79dB with 1dB steps.
Subwoofer attenuator
The Subwoofer output is a single ended mono output. The attenuator is exactly the same
like the other speakers.
shows the attenuation as a function of frequency at a center frequency of
