Parallel Compressor
The DS1-MK3 can be used in parallel compres-
sion mode, where the compressed signal is add-
ed to the straight signal.
How to activate parallel compression: Touch
the gain / data controller (
). In the menu that
appears, mark the checkbox with softkey A.
When using parallel compression, the DS1-MK3
is able to run in frequency selective or in full
band mode.

Parallel full band compression: As can be
seen in (Graphic 18), the input signal and the
compressed signal are summed. The gain
makeup value can be used to control the
amount of compressed signal. The pre-limiter
gain can be used to scale the mix before limit-
ing.
Parallel band selective compression
(Graphic 20): To add even more subtle com-
pression, the compressed signal can be filtered
before compression. Using the monitor function,
one can listen to the filtered signal for optimal
crossover setup.
Why parallel compression?
Read this quote from Bob Katz from the Master-
ing Webboard:
“You want a patch that compresses without
stomping on the attacks at all, preserves transi-
ents 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 in-
ner details without losing breathing, and hardly
affecting 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 En-
hancer, by split band [i.e. parallel] compression,
so that (for example) high frequency inner de-
tails at low levels are enhanced. ”
This last paragraph refers to parallel band selec-
tive compression (crossover in highpass mode).
