UPDATE HISTORY
Update f om DS1 to DS1-
MK2 v1.0 o v1.1
The main differen e between these two versions
is the ability of the DS1-MK2 to a ept 88.2 /
96kHz input signals. Contrary to the DS1, where
double sampling pro essing was only used in
ompressor mode, the DS1-MK2 now uses inter-
nal up- and downsampling stages and all pro-
essing is at 88.2 / 96 kHz.
There is a ompletely new feature available in
the DS1-MK2, the upward expander. This is the
logi al extension of the ompressor. Just turn
the ratio ontroller ounter lo k wise to experi-
en e this new sound. New s ale range on p. 26.
The DeEsser se tion has been enhan ed with a
new rossover, whi h overs the whole audio
bandwidth (the DS1 used 271 Hz as lowest ut-
off frequen y, the DS1-MK2 an now be tuned
down to 41 Hz). New s ale range on p. 25.
And for those who like it hot, there is a new
peak limiter se tion added in series to the om-
pressor / de-esser, whi h uts down spikes
above 0.0dBFS. Read about its operation on p.8.
Update f om DS1-MK2
v1.0 o v1.1 to DS1-MK2
v1.3
The main new enhan ement is the parallel om-
pressor option. To read about operating and
options of the parallel ompressor, turn to p. 14.
This way of using a ompressor was motivated
by Bob Katz, here is what he says about it on
the Mastering Webboard:
“You want a pat h that ompresses without
stomping on the atta ks at all, preserves transi-
ents but gives you great inner detail? ...
You have one ontrol, one ontrol only, and that
is the output level of the ompressor [gain
makeup], the ‘side hain’. You an bring out in-
ner details without losing breathing, and hardly
affe ting the upper dynami s at all. Works great.
Not just great, absolutely fantasti ally. Fattens
bass instruments without ausing breathing or
pumping. You name it, it works very well.
Variations: Use it like the Dolby Spe tral En-
han er, by split band [parallel] ompression, so
that (for example) high frequen y inner details
at low levels are enhan ed. ”
The other hange in ar hite ture is the addition
of a se ond gain before the safety limiter, re-
ferred to as pre-limiter gain. The old overall gain
is also still available. Read on p. 8.
Also, the s ales of the gain, gain makeup and
ratio parameters has been modified to suit us-
tomer feedba k. New values on p. 26.
Update f om DS1-MK2
v1.3 to DS1-MK2 v2.0
In the v2.0 version POW-R dithering apabilities
have been added. The dithering menu now has a
"setup" entry whi h gives you a ess to the
three POW-R algorithms.
Update f om DS1-MK2
v2.0 to DS1-MK2 v2.1
New Feature: Safety Limiter is now also of auto
release type. No hanges to the user interfa e.
Update f om DS1-MK2
v2.x to DS1-MK3 (v3.0)
After several years of the DS1’s use in mastering
and re ording studios world wide we have gath-
ered and implemented a list of most wanted
features suggested by our ustomers.
These in lude:
-Ganged or unganged ontrol, i.e. independent
parameters in L/R or M/S possible
-M/S or L/R pro essing
-Swit hable side hain link
-Continuously variable signal sensing from Peak
to 800ms RMS
