The Bose T4S ToneMatch Mixer is a compact 4-channel digital mixer featuring a powerful DSP engine, an intuitive user interface, and built-in USB audio functionality, making it well suited for capturing live performances, podcasting, livestreaming, and more. The ToneMatch mixer is designed to interface with the Bose L1 or F1 sound system for full end-to-end tonal control.

The integrated ToneMatch processing and zEQ help you get a great sounding mix quickly and effectively. The Bose ToneMatch processor is natural sounding on vocals and instruments, while the zEQ focuses your tone for effective adjustments on the fly. The illuminated, tactile controls, and indicators offer quick, spontaneous sound adjustment even on dark stages. Additionally, the ToneMatch system offers advanced features such as tap-tempo delay, a built-in chromatic tuner, and recallable scenes to create a professional onstage companion for performing artists.

Each channel offers a trim knob, a channel edit button, an FX mute button, a volume knob, and a dedicated channel mute. The main output features a master volume control, an independent headphone volume control, and phantom power for working with condenser microphones. The Bose T4S ToneMatch Mixer ships with a magnetic cover and a ToneMatch cable, which powers the mixer when connected to an L1 PA system. When using the T4S without an L1 system, a dedicated power supply (available separately) is required. Connection to a host computer requires a separately available USB Type-B to USB Type-A cable.
