Dvr-2
Introduction
DVR-2 offers Reverb and System 6000 users a pristine
Generic Reverb with true vintage flavor. Generic Reverb is
complementary to Source Reverb, and both types are at
disposal in the 6000.
You can read more about Generic Reverb elsewhere in this
manual, but the term is used to describe a flattering sustain
effect, which can be added to many sources of a mix. It
produces little character but also does no harm, because
the effect is blurred or washed out. Instead, it adds a good
sense of spaciousness and more or less pronounced
modulation.
Recreation of a Classic
The development of DVR-2 has been a process extending
several years, with the goal of recreating the most shining
GenericReverbofalltimes,theEMT250.Aparticularly
wellsoundingmachinewasrefurbished,andinthemaking
of DVR-2 many design disciplines were involved...
Hardware technical: What was the precision of converters
and how where they implemented in the eighties with
emphasis,blockscaling,linearity,filtersetc?Howmuch
processing and RAM was available, what was the sample
rateetc?
Softwaretechnical:Whichkindofprocessingwasdone
in discrete circuitry, what type of truncation and noisefloor
artifacts would result, how could the low sample rate be
mimickedprecisely,andhowcouldallofthisbetransferred
to a modern DSP platform.
Perceptual:Makingsurethequalitiesoftheoriginal
processor was preserved. Sweet modulation, spectral
characteristics, spaciousness, distortion, saturation etc.
Hundreds of hours spent listening and measuring.
User:ThefourbasicparametersoftheEMT250were
carefullylaidout,offeringaremarkablysimpleuser
interface with complex, yet optimized interactions under the
hood. DVR-2 is a resemblance of that including range and
coarseness of parameters. Also the original I/O structure is
keptwithMonointoStereoandQuadout.
Better than the Classic?
While DVR-2 in Normal mode is very close to the sound
ofaperfectlyaligned250,havingusedmuchDSPpower
to mimic artifacts of old hardware, the algorithm can also
beputinaHighResolutionmode.Usingthisfunction,
the noisefloor is much lower, but use your own ears to
determine if this is actually a plus for a specific situation.
Please note: Many of the constraints and criteria listed
aboveproducenon-linearaudiobehavior,makingit
impossible to obtain more than a static and crude result if
trying to sample an original processor. A minute emulation
doesmorejusticetotheoriginalfromanaudiopointof
view,andcanalsostillbeadjusted.
The DVR-2 Source algorithm occupies:
@ Normal Sample Rate : 1/4 DSP Resource
@ Double Sample Rate : Currently not available
Algorithm Inputs/Outputs are distributed as follows:

Decay
Range:0.2-4.5s
AdjuststheMasterDecaytime.
xLo
Range:0.5to2.0
Decaymultiplierforlowfrequencies.Forax1.0setting,low
frequency decay will equal the Decay setting.
xHi
Range:0.5toMax.
Decaymultiplierforhifrequencies.Forax1.0setting,high
frequency decay will equal the Decay setting.
Pre Delay
Range: 0, 20, 40, 60ms
Pre delay is the amount of time from an input is received
until reverb starts building up at the output.
