Stam Audio 4K-5+ Stereo Buss Compressor

The Stam Audio 4K-5+ Stereo Buss Compressor is a true 500 series recreation of the legendary G Series console compressor, designed to deliver the same unmistakable glue, punch and musical character that made the original a favourite across decades of hit records. While many clones aim to capture the basic behaviour of the original, the Stam Audio 4K-5+ sets itself apart by faithfully replicating the core circuitry that defined the sound of the early Oxford desks, starting with the heart of the unit—the VCA.

At the centre of the Stam Audio 4K-5+ are two SA-202C VCA cans, Stam Audio’s painstakingly recreated, fully discrete versions of the original DBX 202C gold modules. These rare components were essential to the tonal character of the original G Series console compressors, offering subtle harmonic distortion, a warm low end, and that musical compression behaviour that ties a mix together. Each SA-202C is hand-assembled and hand-matched in Chile using original construction methods, including transistor matching and value selection, taking an entire day just to produce a matched pair. This level of detail is what allows the Stam Audio4K-5+ to deliver not just the behaviour but the genuine sonic fingerprint of the vintage originals.

To further match the response and tonal integrity of the G Comp, Stam Audio auditioned sixteen different capacitor brands before selecting Elna Silmic capacitors for their superior stereo image and extended frequency response. Combined with a no-compromise approach to every part of the circuit, the 4K-5+ achieves a level of authenticity that no software emulation or budget clone can match.

The result is a unit that not only captures the compression style and response of the original, but also reproduces the distinct coloration and harmonic richness that gave early SSL desks their reputation for cohesion and weight. Whether used on a mix bus or drum bus, the Stam Audio 4K-5+ enhances the clarity, depth, and impact of a mix without sacrificing detail. Even subtle adjustments yield dramatic improvements in tightness and power.

Built entirely by hand and calibrated in Stam Audio’s Chilean workshop, each unit undergoes a double quality check and a 24-hour burn-in to ensure long-term reliability and consistency. This hands-on, small-batch approach allows Stam Audio to maintain the quality and accuracy required to honour the legacy of the original design.

Ideal for hybrid mixing environments, the Stam Audio 4K-5+ is the perfect analogue complement to digital workflows. It adds musical weight and glue to your mixes, offering the timeless sonic character of the G Series console in a compact and accessible 500 series format. With the Stam Audio 4K-5+, Stam Audio delivers not just another compressor, but a genuinely faithful and character-rich tool for professional mix engineers seeking classic results.
