7.3 HPF (Input Channels)
HPF –
A High Pass Filter (HPF) is available on every input channel and features an
adjustable slope and frequency.
• Switch in or out using the on-screen button or using the dedicated HPF ‘In’ key.
• Touch the HPF Frequency value to select it, then adjust using the touchscreen
rotary, or use the dedicated HPF ‘Freq’ rotary to affect the selected input channel.
• Touch the current ‘Slope’ value to select from different filter slopes.
HPF Frequency = 20Hz to 2Khz
Slope = 12dB, 18dB, 24dB (attenuation per octave) Butterworth
The HPF is also visible on the PEQ processing screen for convenience and can be
stored and recalled with PEQ settings. Though as a separate process at a different point
in the signal path, HPF does not contribute to the PEQ response curve.
