Appendix D: Klark Teknik DN780
Reverb
This appendix contains parameter application notes for the DN780 reverb internal effect
on the PRO6. This is followed by information on the special effects program and
technical specifications of the PRO6’s DN780.
Parameter application notes
This section provides application notes on the parameters of the DN780 Reverb effect.
Pre-delay
0 to 990 milliseconds (ms) of pre-delay is available allowing a very wide range of
control. Delays of less than 30ms closely integrate the direct and reverberant sounds;
often a desirable feature on percussive sounds. Delays of 50ms or more cause the
direct and reverberant sounds to separate and convey a feeling of depth and distance to
the simulated environment. Delays above 2300ms are used for creating special effects.
Pattern
The pattern control alters the ‘density’ of the early reflections. It is adjustable from 0 to
9 as shown on display f1, with 0 giving a low density or ‘grainy’ character to the early
reflections and 9 producing a high density effect.
Level
The level control functions convincingly as a ‘depth’ control, altering the apparent
distance between the sound source and the listener. It is adjustable from 0 to 9 as
shown on display f2, with 0 being relatively distant and 9 bringing the sound source
closer.
Decay
The reverberation decay time is adjustable from 0.1 to 18 seconds, depending on room
size, changing the reverberant field from a virtually dead sound to a totally surreal
effect. Short decay times, under one second, are essential for authentic small room
simulation and also extremely useful for ambience applications where classic
reverberation is not wanted. Reverb times of 1 to 4 seconds cover the majority of
normal applications where classic reverberation is required. Longer decay times are
available for special effect applications.
LF key
LF is adjustable to ±7, depending on room size and decay time, as shown on display f3.
An increase in LF decay time is generally desirable on simulations of large halls, since
low frequency sounds suffer less than higher frequencies from absorption in air. Very
small spaces usually need the ‘thin’ sound created by reducing LF decay.
