Mercury Studio Soul™ 2548 SS2548 – Fully Balanced, Class A Discrete 24-Channel Analog Summing Mixer Expansion for 48:2 Mixing System with Transformerless Inputs

OVERVIEW

The Mercury Studio Soul™ 2548 SS2548 expands the Studio Soul ecosystem into a full-scale 48:2 analog summing system, allowing engineers to scale their workflow without sacrificing sonic integrity. Designed as a 24-channel expansion unit, it maintains the same fully balanced, Class A discrete architecture as the main system.

With transformerless inputs across all channels, the SS2548 focuses on transparency, precision, and headroom, ensuring that extended mixes remain clean and accurate even in complex sessions. It is engineered to integrate seamlessly into existing Studio Soul workflows, functioning as an extension rather than a separate system.

Whether used in large-scale production environments or hybrid DAW studios requiring expanded channel capacity, the SS2548 preserves stereo imaging, mix depth, and clarity while allowing engineers to build larger, more detailed mixes.
