Get your perfect sound fast.

Never run out of options with channel-independent EQ, dynamics and effects. Bose ToneMatch processing delivers natural-sounding vocals and instruments, while Bose zEQ focuses your tone for effective adjustments on the fly.

Seamless control on stage

Illuminated, tactile controls and indicators let you quickly and easily make sound adjustments, even on dimly-lit stages. And the T4S is a true companion on stage with performance-enhancing features like tap tempo delay, built-in chromatic tuner, and recallable scenes

Unprecedented connectivity with control

The T4S offers a lot in a compact package. Four main channels, high-quality audio preamps, XLR-combo jacks for microphones or instruments, and switchable phantom power. Plus, there are two Aux sends, two Aux inputs, USB-A and -B for USB drive playback or PC/Mac interfacing, two ToneMatch outputs for digital audio (with remote power), a dedicated headphone jack, and balanced ¼" TRS analog outputs.

Ready to perform

The rugged T4S includes a magnetic cover to protect the controls and connectors and comes with a ToneMatch cable for direct-connecting to select Bose L1 systems. There’s even a convenient bottom insert so you can mount the T4S to keep it in reach.
