Mercury Studio Soul™ 242 Pro SS242PRO – Fully Balanced, Class A Discrete 24:2 Analog Summing Mixer with 24 Transformer-Based Inputs

OVERVIEW

The Mercury Studio Soul™ 242 Pro SS242PRO builds on the foundation of the SS242 by introducing transformer-balanced inputs across all 24 channels. This addition enhances harmonic richness, stereo depth, and perceived width, giving mixes a more cohesive and dimensional character.

Engineered around a fully balanced, Class A discrete signal path, the Pro version delivers both precision and colour, allowing engineers to shape tone at the summing stage rather than relying solely on plug-ins or outboard processing. The transformer input stage introduces subtle saturation and natural glue, ideal for dense mixes that require cohesion without sacrificing clarity.

Like the standard model, the SS242PRO integrates seamlessly into hybrid DAW environments, acting as the central analog summing hub of a modern studio. It retains full routing flexibility, stereo EQ, and insert capabilities while adding a more musical, harmonically rich character.
