Mercury Studio Soul™ 2548 Pro SS2548PRO – Fully Balanced, Class A Discrete 24-Channel Analog Summing Mixer Expansion for 48:2 Mixing System with 24 Transformer-Based Inputs

OVERVIEW

The Mercury Studio Soul™ 2548 Pro SS2548PRO extends the Studio Soul system with 24 transformer-balanced input channels, adding harmonic richness and subtle analog character to expanded 48:2 workflows. This model is designed for engineers who want both scalability and tonal enhancement within a unified system.

The transformer input stage introduces natural saturation, depth, and cohesion across multiple channels, helping larger mixes feel more connected and musically balanced. While maintaining full Class A discrete architecture, the Pro version adds a layer of analog character that enhances density and stereo imaging.

Fully integrated into the Studio Soul ecosystem, the SS2548PRO provides seamless expansion without workflow disruption. It retains full connectivity, headroom, and clarity while offering a more coloured, musical summing experience ideal for complex productions.
