UPDATE HISTORY
Update from DS1 to DS1-MK2
v1.0 or v1.1
The main difference between these two versions
is the ability of the DS1-MK2 to accept 88.2 /
96kHz input signals. Contrary to the DS1, where
double sampling processing was only used in
compressor mode, the DS1-MK2 now uses inter-
nal up- and downsampling stages and all process-
ing is at 88.2 / 96 kHz.
There is a completely new feature available in the
DS1-MK2, the upward expander. This is the logi-
cal extension of the compressor. Just turn the
ratio controller counterclock wise to experience
this new sound. New scale range on p. 19.
The DeEsser section has been enhanced with a
new crossover, which covers the whole audio
bandwidth (the DS1used 271 Hz as lowest cutoff
frequency, the DS1-MK2 can now be tuned down
to 41 Hz). New scale range on p. 18.
And for those who like it hot, there is a new peak
limiter section added in series to the compressor
/ de-esser, which cuts down spikes above
0.0dBFS. Read about its operation on p.7.
Update from DS1-MK2 v1.0 or
v1.1 to DS1-MK2 v1.3
The main new enhancement is the parallel com-
pressor option. To read about operating and op-
tions of the parallel compressor, turn to p. 12.
This way of using a compressor was motivated by
Bob Katz, here is what he says about it on the
Mastering Webboard:
“You want a patch that compresses without
stomping on the attacks at all, preserves tran-
sients but gives you great inner detail? ...
You have one control, one control only, and that
is the output level of the compressor [gain
makeup], the ‘sidechain’. You can bring out inner
details without losing breathing, and hardly af-
fecting the upper dynamics at all. Works great.
Not just great, absolutely fantastically. Fattens
bass instruments without causing breathing or
pumping. You name it, it works very well.
Variations: Use it like the Dolby Spectral Enhan-
cer, by split band [parallel] compression, so that
(for example) high frequency inner details at low
levels are enhanced. ”
The other change in architecture is the addition of
a second gain before the safety limiter, referred
to as pre-limiter gain. The old overall gain is also
still available. Read on p. 7.
Also, the scales of the gain, gain makeup and ratio
parameters has been modified to suit customer
feedback. New values on p. 19.
Update from DS1-MK2 v1.3 to
DS1-MK2 v2.0
In the v2.0 version POW-R dithering capabilities
have been added. The dithering menu now has a
"setup" entry which gives you access to the three
POW-R algorithms.
