6.4.1 Using the High-pass Filter (HPF Enable)
The high-pass lter lters all frequencies below the specied frequency. Input HPF and Low Output HPF
are available. Input HPF affects all output channels; Low Output HPF affects only the lowest output of the
Module. These two different modes of operation are provided in order to satisfy the requirements of various
loudspeaker manufacturers’ required signal-processing congurations.
To set the Low Output HPF:
1. Tap HPF ENABLE, then tap HPF Select.
2. Select a lter from the scroll bar (24 dB or less).
3. Tap HPF Set, then YES to the warning message.
To change the HPF to affect all outputs (Input HPF):
1. Tap CROSSOVER FUNCTIONS, then HPF Functions.
2. Tap INPUT HPF.
While in this mode, move the HPF center frequency, and note how it affects all outputs of the Module
The center frequency of the HPF can be set to a
minimum of 10 Hz using the Filter Edit function.
6.4.2 Filter Edit
Tap FILTER EDIT to manually enter values for a selected lter using the on-screen (or external) keyboard.
The values available for adjustment depend on whether a crossover or PEQ lter is selected. For a cross-
over, HPF or LPF only the frequency can be edited; for a Parametric EQ lter the gain (dB), frequency (Hz),
and width (octave) can be edited.
To manually edit a lter:
1. Tap the lter box, then tap FILTER EDIT.
2. Tap the value to edit at the top of the screen (highlighted in blue).
3. Enter the value using the on-screen (or external) keyboard, and tap OK.
4. Tap FILTER EDIT again to exit this mode.
