The is a versatile, extremely clean Mono VCA compressor with a wide range of attack and release times, that allow for multiple applications.


The main feature is, as the name indicates, the filters in the sidechain. These sophisticated control options are unique and open new possibilities for shaping sound. Use in mono on individual tracks or in stereo on the 2-Bus for mixing or mastering.


The focus of this unit is on the high-pass and the low-pass filters for the sidechain. The filters range from 20Hz - 200Hz, 150Hz - 2.3kHz, and 1.5kHz - 20kHz, respectively.


The Listen feature lets you listen to what the side chain is receiving and can be used as a high quality band-pass filter.

The compressor ratios are 1:2 (soft), 1:4 (medium) and 1:10 (hard), attack times range from 0.1ms to 120ms and release times range from 0.1ms to 1.2s.


The unit comes with an external power supply (110-240V) and a standard IEC cable. The stereo bundle includes a link cable.


Inspired by Luca Pretolesi’s (Diplo, Major Lazer u.a.) workflow and techniques, our team created a new way of sidechain based compression.
