Playback Path 7-Band Parametric Equalizer
The playback path DSP features a 7-band parametric
equalizer with clipping detection and a programmable
pre-attenuation amplifier (Figure 25). Each of the 7 bands
is a full, individually programmable digital biquad filter.
The chosen configuration for any given band applies to
both the left and right playback channels.

The parametric equalizer can be enabled in a 3-band,
5-band, or the full 7-band configuration (Table 50). Once
the parametric equalizer is enabled, the clip detec-
tion can be set and the level of preattenuation can be
adjusted from 0dB down to -15dB (denoted A
Table 51). No single band biquad filter can be set to a gain
greater than ±12dB, to a Q greater than 10, or to below
a minimum f
Characteristics table.
