Rockruepel Sidechain Stereo - VCA Compressor with Sidechain Filters

Rockruepel | German boutique manufacturer 

The Rockruepel Sidechain.One is a versatile, extremely clean Mono / Stereo 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 sidechain.one 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.

Trendsetting

Using sidechain frequencies has become a standard technique in mixing and mastering. Most of the time, it is used in the digital domain with plug-ins that can offer this flexibility and versatility thanks to the nature of digital audio. One of the trendsetters for this approach is Luca Pretolesi. His signature sound is characterized in part by his use of sidechain frequencies in the compressor for a variety of styles, in mono, stereo and specially in M/S applications. Inspired by his workflow, we created a compressor that brings the discreet and pure processing of a digital plug-in into the analogue realm. This is sidechain.one.
