High Pass Filter
Adjust the High Pass Filter frequency by turning the rotary encoder. You can switch the high
pass filter off by turning the rotary encoder down (counterclockwise) until the frequency passes 20Hz.
Press the rotary encoder to change the filter type. Select the type by turning the rotary encoder.
You can choose from: Butterworth 6dB, Bessel 6dB, Butterworth 12dB, Bessel 12dB, Linkwitz
Riley 12dB, Butterworth 18dB, Bessel 18dB, Butterworth 24dB, Bessel 24dB. Higher order
filters may be set by adding filter sections in the PEQ blocks (see below).
Enable or disable the High Pass filter by rotating the encoder between on and off.

Parametric Equalizer (PEQ)
There are 10 bands of parametric equalization. Each band can be adjusted freely over the
complete frequency range of 20Hz to 20kHz. Adjust the frequency by dialing the rotary encoder.
Press the rotary encoder to select the parameters. The available parameters are: Frequency
(20Hz to 20kHz), Gain (-12dB to +12dB), Q (0.2 to 25), Enabled (on or Off), Type (Bell, High
Shelff, Low Shelf, Notch, All Pass, Band Pass, High Pass, Low Pass). For the Shelving filters,
the Q value sets the steepness of the filter in dB/Oct.
