N-220 Silenzio denoiser module for Eurorack / Doepfer A100 system.

From the top down:
bypass button + LED
L+R input jacks
Sensitivity knob
Filter LEDs
L+R outputs

The N-220 Silenzio can help to remove unwanted noise from noisy audio signals. It cannot remove crackling, hum or buzz or similar disturbances. It is based on dynamic noise reduction system (DNR/DNL), filter allows passing hi-freq audio signal if signal amplitude is large enough to mask noise. If signal level decreases internal low pass filter frequency decreases too filtering noise (and some hi-freq content). Filter sensitivity is set using knob. You can easily compare processing depth by listening and bypassing Silenzio using bypass button. Mono or stereo signals can be processed (mono signals can go through filter twice if L-in and R-out are used).

Width: 4TE/ 4HP/ 20mm
Depth: 40mm /1,6″ max.
Current: 30mA max.

Double check power connection before powering your system please.
„Red strip“ means -12V connector side in Eurorack standards.
In some power distribution systems connector key can be reverted.
In this case cut connector key and plug power connector right way (with respect to red strip) or use different power cable appropriate to your power system.
