A 2nd order high-shelf filter with frequency variable over the range 10Hz to 25kHz, and
boost/cut from –15 to +15dB, and slope from 6 to 12dB/Octave.
Eight bands of parametric equalizer, each band having frequency variable over the range
10Hz to 25kHz, bandwidth variable from 0.18 to 5.6 octaves (Q 0.15 to 8.1), and
boost/cut from –15 to +15dB.
Delay adjustable up to 90ms.
Adjustable input gain from –30 to +15dB, mute and polarity.
Adjustable output gain from –30 to +15dB.
Equalisation Filters
The eight parametric equalisation filters may each be used to emphasize (by applying a
positive Gain parameter setting) or de-emphasizing (by applying a negative Gain
parameter setting) a range of frequencies centered on the setting of the Frequency
parameter, and encompassing a frequency range determined by the Bandwidth parameter
setting.
The two shelving filters allow all frequencies below that of the frequency parameter (for
the Low shelf) or all frequencies above that of the frequency parameter (for the high
shelf) to be emphasized (by applying a positive Gain parameter setting) or de-emphasized
(by applying a negative Gain parameter setting).
The ten filters are used in combination to achieve the desired response across all
frequencies.
Bridge Mode
When the amplifier is set to Bridge Mode, it uses two amplifier channels to drive one
loudspeaker with greater power. In this mode, there is only one set of Output controls per
pair of amplifier channels since both of the amplifiers in the pair are driven with the same
signals, as determined by the channel 1 (or channel 3) controls.
