In cooperation with the Pure Notes Company, Weiss developed a State of the Art Denoiser / Declicker and K-Stereo ambience regenerator unit.

Features are: (all working in real time):
- Denoiser with three operation levels (auto / semi auto / manual), which allow for simple, intuitive operation as well as for elaborate parameter tweaking when necessary
- Declicker
- K-Stereo process (under license from Bob Katz)
- M/S encoder / decoder

Excerpt from the brochure:
Denoiser / Declicker with three operation levels (auto / semi auto / manual), which allow for simple, intuitive operation as well as for elaborate parameter tweaking when necessary,
K-Stereo process for Ambience Enhancement,
M/S encoder / decoder for stereo width control.
The DNA1 uses a novel approach to noise reduction which can remove a wide range of noise types without affecting the musical characteristics, stereo imaging or the ambiance of the original.
The K-Stereo ambience enhancement processor recovers lost ambience, space, depth, imaging and clarity.
The M/S encoder / decoder and level control portion allows for independent balance and stereo width tweaking.
