Allen&Heath DP 1000 USER GUIDE - Manual (Page 33)

Note that if you add large amounts of boost you may
have to reduce the channel
GAIN to prevent the signal
clipping. This will be indicated by PEAK flashing red
in the PFL key. The effect of adjusting the parameters
is displayed graphically as a frequency response
versus dB level curve. Notice the effect the controls
have on both the sound and the displayed response
curve.
The LF band can become a sweepable 12dB per
octave high pass filter (HPF) to cut low frequencies.
This is useful in eliminating the low ‘popping’ sound
associated with close vocal miking or to cut out low
frequency noise. Simply turn the LF gain control to
minimum and adjust the frequency control for the
required cut off point.
Press the OUT key to switch the EQ in or out. Press
RESET to instantly reset the EQ flat. You can copy the
EQ settings to another channel by pressing the
COPY
key. The PASTE key will illuminate. Select a
different EQ, press PASTE to see the copied settings
instantly take effect. The PASTE key remains lit to
tell you that valid copy data is available until you
select an unrelated screen or switch the console off.
Return to EQ8. Change the settings and then press
UNDO. This restores the previous settings current
when the EQ screen was selected or when saved to
the undo buffer by pressing
ENTER. This is useful to
mark settings for comparison.
Press the EQA or EQB key to adjust the output graphic
equalisers.
This divides the frequency range into ten bands
which can be independently boosted or cut using the
soft strip controls. This is used to adjust for room or
loudspeaker acoustics. Press
OUT to switch the EQ
out, and RESET to instantly set it flat. EQ A and B
can be linked using the AB LINK menu option for
stereo operation.

Add some reverb to simulate the effect of playing in
a large hall or similar environment. Press the
FX2
select key. This displays the level of reverb for each
channel and the name of the effect type selected.
The soft strip becomes the effects send controls, one
for each channel. This sends the signal to the internal
effects processor where the reverb effect is created.
The ‘wet’ reverb signal is returned via the
FX2 fader
channel and added to the ‘dry’ signal routed directly
to the mix.
Start by raising the FX2 FADER to ‘0’. Now turn the
send control. The reverb effect should be heard
added to the mix. The amount of reverb signal can
be separately adjusted for each channel. The overall
reverb level can be adjusted using the fader. Press
MUTE to turn the effect off and on. Press RESET to
set all the sends to minimum.
Press the FX2 key again to access the parameter
screen. Use the soft strip controls 4,5,6 and 7 to
adjust the available parameters for the selected effect.
Press
RESET to return to the default settings. You can
scroll through and listen to the effects types available
and view their parameter settings using the
WX
cursor keys or soft strip control 10. Press UNDO to
restore the previous effect selected.
Depending on the effects type selected the following
parameters are available:
• PDY = Pre-delay – time before effect starts
• DLY = Delay - sets echo or delay time
• DMP = Damping – decay of high frequencies
• DIF = Diffusion – ‘thickness’ of the sound
• DCY = Decay – how fast the effect fades
• REG = Regeneration – feedback to repeat
• DEP = Depth – how strong the effect is
• SPD = Speed – how fast the effect repeats
• DRY = Dry signal added to the effect
