The combination of the extremely versatile Serge Variable Q Filter (VCFQ) and the R*S Stereo Mixer / Panner is an ideal output module which combines high-end audio specs (including balanced outputs) with massive sound-shaping power.
The unique Serge Variable Q Filter (VCFQ) is an excellent general-purpose VCF that provides simultaneous low-pass, high-pass, band-pass and notch (band-reject) outputs combined with unique flexibility. Its trigger in, LOW mode and self osciallation allow a variety of uses from Oscillator to VC processing. With the support and approval of Serge Tcherepnin, the Random*Source version of the filter uses high-end VCAs by THAT for superb audio performance.
The Equal Power Stereo Mixer / Panner by Random*Source is designed to emulate the behavior of the famous Serge VCAs. It uses some of the best audio components available today including THAT2180 VCA chips. Version 1.1 contains a number of additions and improvements that were adopted in surface mounted technology (SMT):
Balanced Outputs, using „a new generation of monolithic audio differential line drivers offering improved performance over conventional crosscoupled designs“ for low noise and distortion. These outputs can be connected to balanced or unbalanced equipment (amplifiers, A/D converters...)
Burr-Brown quad op-amps (OPA4134) in the audio path.
Optimized value set and easier calibration / setup.
The R*S Stereo-Mixer has two independent channels for stereo panning and provides level control (or enveloping) as well as voltage controlled panning. Two Aux inputs allow to mix in other signals (not affected by control voltages or knobs) and to chain mixers. The output is available at a pair of banana jacks as well as (6.35mm / 1/4") TRS jacks (phone connectors) for connecting to external amplifiers, ADCs etc.
Module is available as a DIY project only.
