several times to step through the channels.
Output low shelf filter
Use the EQ> menu item to edit the low shelf filter for the
output channel. You can update the frequency, slope and
gain. For details of FIR, see output FIR (page 27). The low
shelf filter is shown as LS in Vu-Net (page 36).
To edit the low shelf filter
1. Press
OUTPUT to select the channel. For details, see
Selecting the output channel (page 24).
2. Press the up arrow button▲several times
untilEQ>appears top left (usually four presses).
3. RotateADJUST(the right-hand dial) to change the
frequency.
4. Rotate

chooseSlopeand rotateADJUST(the right-hand dial)
to update the slope.
5. RotateSELECT(the left-hand dial) to chooseGainand
rotate

Output low pass filter
Use the LPF menu item to edit the low pass filter for the
output channel. You can update the frequency and the
filter type. The filter types available are the same as for
the
high pass filter (page 28).
To edit the low pass filter
1. Press OUTPUT to select the channel. For details, see
Selecting the output channel (page 24).
2. Press the up arrow button

frequency. To remove the low pass filter, turn the dial
to the right until

5. Press UTILITY to exit the menu or press OUTPUT
several times to step through the channels.
Output high pass filter
Use the HPF menu item to edit the high pass filter for the
output channel. You can update the frequency and the
filter type:

Hardman filter
The Hardman type filter is always described by its order.
This is because the filter becomes progressively steeper
rather than following a linear slope and so a dB/octave
description is not accurate.
Linear impulse response filter
Unique to Martin Audio, linear impulse response (LIR)
crossover filtering gives a linear phase crossover that has
a constant delay regardless of frequency. This is unlike
other types of crossover that delay different frequencies
to a different extent, thus smearing the arrival time. The
LIR crossover can therefore be described as having a
flat group delay response and is thus entirely free of
group delay distortion. Common FIR filtering can provide
this too, but FIR filtering does have complications and
disadvantages when compared with LIR filtering.
The shape of the LIR crossover filter is similar to
a 4th order Linkwitz-Riley filter, and maintains zero
phase difference between the adjacent bands across the
crossover region to keep the polar response rock steady.
Note that very narrow bandwidths are not possible with
this crossover type. If the low pass frequency is too close
to the high pass frequency, then the filter will ‘mute’.
