Bose T4S ToneMatch – a four-channel digital mixer with ToneMatch processing and zEQ, four combo XLR/1/4" inputs with switchable phantom power, powered directly from an L1 system's ToneMatch port or through an optional power supply.
Four channels, one cable to the L1 system
The T4S ships with a ToneMatch cable that carries both digital audio and power from an L1 Pro, L1 Model II, or 1S power stand to the mixer – unlike the T8S, which requires that cable as a separate purchase. For a solo performer or duo, that means one extra cable instead of a dedicated power supply sitting next to the mixer, which matters when playing venues with limited outlet access, like a restaurant terrace or an outdoor setup.
Scenes matched to a specific part of the set
Five saved Bose scenes – Singer/songwriter, DJ/playback, Drums and bass, Electric works, and factory settings – switch the entire routing, EQ, and effects chain with one knob, so a duo moving from an acoustic set to laptop-based backing tracks doesn't need to manually reprogram channels between songs. A built-in chromatic tuner and tap-tempo delay remove the need for a separate stage pedal, and the USB-B output lets you record or livestream the show to Facebook or Instagram at the same time.
