6.2.6 Parametric Equalisation (Pages 7 to 12)
The DN9848E provides six parametric equalisation
stages on each output channel, for equalising the
output signal in respect of loudspeaker and/or
system characteristics. The first and last of these
PEQ sections can, alternatively, be configured for
lower and upper shelving equalisation. All the PEQ
sections can be used across the full range from
20Hz to 20kHz and are set independently via their
own menu page.
To set a PEQ
1
Set a centre frequency (21 steps per octave) and bandwidth (0.08 to 3 Oct) for the PEQ
section, using the left and centre
DATA ENTRY
control knobs, respectively.
Or:
Switch to an LEQ/HEQ setting with a 6dB or 12db slope by turning the centre control knob
clockwise beyond 3 Oct (see below). Use the left control knob to set the LEQ/HEQ frequency.
2
Turn the right control knob to set the amount of attenuation/boost from -12dB and +12dB.
If a PEQ section is not needed in the set up, set its level to 0dB.
Any PEQ can be used as the reference
frequency for the Phase Shifter (see
Section 6.2.4)
