Virtual DN780 Reverb effect
The Virtual DN780 Reverb provides emulation of the vintage Klark Teknik DN780 Digital
Reverberator/Processor unit. The DN780 is not just a reverberation device, it also gives
the user a unique and flexible means of producing realistic acoustic simulations for
environments of all types and sizes. The provision of effects programs further extends
this versatility, making it a very powerful acoustic processing package.

Item Control Function
1 LF (low frequency)
control knob
REVERBERATION section control that adjusts the
decay time at the low end of the reverb spectrum.
Range is from -7 to +7.
2 HF (high
frequency) control
knob
REVERBERATION section control that adjusts the
decay time at the high end of the reverb spectrum,
which sets the absorption characteristic of the
simulated space. Range is from -7 to +7.
3 ROOMSIZE
control knob
Adjusts the average dimension of the simulated
space. Range is from 8 to 90 metres. A momentary
mute is implemented when this control is adjusted.
4 DECAY control
knob
REVERBERATION section control that sets the
overall (mid-band) reverberation decay time. Range
is from 0.1 to 18 seconds, depending on room size.
5 LEVEL control
knob
REFLECTIONS section control that acts as a ‘depth’
control by altering the apparent distance between the
sound source and the listener. Alternatively, adjusts
the input level for Sound-On-Sound/Infinite
Room. Range is from 0 to 9.
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.
