Bose 785403-0110 T4S ToneMatch 4-Channel Mixer

The Bose T4S ToneMatch Mixer is a purpose-built 4-channel digital mixer designed for solo performers, duos, and small ensembles who need professional sound with minimal setup time. Its onboard DSP engine delivers studio-quality effects including reverb, delay, compression, and EQ, all accessible through an intuitive interface that lets you shape your sound without diving into complex menus. The proprietary ToneMatch processing technology takes things further by offering instrument-specific presets — modeled on real acoustic signatures — that instantly optimize the EQ curve for vocals, guitars, violins, and other common performance sources.

Each of the four channels features a high-quality preamp with an XLR-combo jack that accepts microphones or line-level instruments, and switchable phantom power supports condenser microphones without external accessories. The ZEQ feature works alongside ToneMatch presets to let you make effective tonal adjustments on the fly, focusing on the parameters that matter most for each source. At just 2.1 pounds and measuring 8.4 x 7.25 x 3.25 inches, the T4S slips easily into a gig bag. When paired with a compatible Bose L1 Model II or L1 Model 1S system, the included ToneMatch cable provides both power and a digital audio connection through a single run, simplifying stage setup considerably. USB connectivity also enables use as a recording interface, making the T4S a versatile tool for both live and studio applications.
