PRO1 Live Audio System
Operator Manual
The parameter controls give accurate adjustment of all reverberation parameters and
allow the engineer to create unique acoustic environments of virtually any type.
6 PATTERN control
knob
REFLECTIONS section control that controls the
‘density’ of early reflections. Selects the number and
spacing of Early Reflections/ADT/Multi-tap delays.
Range is from 1 to 9.
7 PRE DELAY
control knob
Controls the amount of delay (in milliseconds)
between the initial signal and the onset of
reverberation. On certain program types, pre-delay
is inserted between early reflections and reverb to
improve authenticity. Its range is algorithm
dependent.
Low level, phase-dependent ‘clicks’ are produced
when pre-delay is altered during the program.
8 List of algorithms
and algorithm
select button
These algorithms emulate the ones on the original
DN780. Use the select button to scroll through the
list to select the one you want.
9 MIX control knob Controls the DRY/WET output mix and ranges from
0% to 100%, respectively.
10 ST stereo input
button
Enhances original algorithm to provide stereo input.
11 Parameter display
panel
Shows the current settings for the selected algorithm.
12 IN button Switches in the Virtual DN780 Reverb effect.
13 LEVEL control
knob
AUDIO section control for adjusting the input level.
Range is from -
4 to +6dB, with 0dB at top dead
centre. This should be set to illuminate the -3dB LED
on the input headroom indicator during loud program
passages.
14 IN button AUDIO section MUTES control for removing feed to
the reverberation section, enabling the decay
qualities of the chosen setting to be confirmed.
15 REV button AUDIO section reverb MUTES control for providing a
rapid means of removing unwanted sounds.
16 Input headroom
indicator
AUDIO section meters, which comprise two
dual-column peak reading LED meters, ranging from
0dB to -27dB in 3dB steps. Each column consists of
10 coloured LEDs. The red LED illuminates at 3dB
before the clipping point, which also provides an
over-range warning for the arithmetical processor.
