Output Channels
15
To set a precise phase shift at a reference frequency
1
Step to the Phase Angle/Ref page shown right.
2
Turn the centre
DATA ENTRY
control knob to
select a phase angle between 0
º
and 180
º
.
Turn the right control knob to set the
reference frequency to HPF, LPF or one of the
six PEQs (set in the subsequent Output menu
pages).
To apply a 1st order phase adjustment in relation to a chosen frequency
1
Step to the All-Pass page, shown right.
2
Turn the right
DATA ENTRY
control knob to
enable a 1st (90
º
) order shift.
3
Turn the left control knob to the required
frequency.
To apply a ‘shaped’ phase transition at a chosen frequency
1
Step to the All-Pass page, shown right.
2
Turn the right
DATA ENTRY
control knob to
enable a 2nd (180
º
) order shift.
3
Turn the centre control knob to select the Q
(slope) and the left control knob to select the
frequency.
6.2.5 High Pass and Low Pass Filters (Pages 5 and 6)
The DN9848E provides the following high and low pass filter (HPF and LPF) options for crossover
purposes:
Butterworth: 6, 12, 18, 24, 36 and 48dB / Octave
Bessel: 12, 18, 24, 36 and 48dB / Octave
Linkwitz Riley: 12 and 24dB / Octave
Peaking (HPF only): 12 and 24dB / Octave 0-6dB Gain
Bypass: No Filter
To add a high/low pass filter to output processing
1
Step to the HPF or LPF page, as required (see
right).
2
Use the left
DATA ENTRY
control knob to specify
the cut-off frequency.
3
Use the centre control knob to select the filter
type and the right control knob to set the
slope/gain. (The right parameter switches
between slope and gain, dependent on the
filter type).
