The Bass adjustment allows you to
change the relative amount of low-
frequency sound globally using a low
shelving filter with a turnover frequency
of 120 Hz.
This means that the setting of the Bass
control is applied to all Sound Modes
and Speaker Groups, and is independent
of the settings of the Frequency Tilt and
Sound Enhance controls. The range of
the controller is from -10 dB to +10 dB in
steps of 1 dB.

all settings of the Bass control. Note that this
response is applied to each input channel.

The Treble adjustment allows you to
change the relative amount of high-
frequency sound globally using a high
shelving filter with a turnover frequency
of 8 kHz.

control is applied to all Sound Modes
and Speaker Groups, and is independent
of the settings of the Frequency Tilt and
Sound Enhance controls. The range of
the controller is from -10 dB to +10 dB in
steps of 1 dB.
