Bose T4S

The T Series: Bose's "Plug-and-Play" Approach to Stage Mixing

With the ToneMatch T4S, Bose presents its philosophy: naturally musical sound and controls designed for efficiency, in an easy-to-transport format. Positioned as a compact solution within the ToneMatch range, it targets lightweight setups where saving time without sacrificing quality is key: ToneMatch presets, quick corrections via zEQ, and ergonomics that put essential controls at your fingertips. Designed primarily to integrate into the Bose ecosystem, it remains equally relevant when paired with active speakers from other brands, whether for front-of-house or monitor use.

Intended Uses and Musicians

The T4S is aimed at artists and technicians who perform back-to-back gigs and need a reliable mix in minutes: singer-guitarists, acoustic duos, keyboard-vocalists, small amplified ensembles, event speakers, houses of worship, rehearsals, or corporate events. Its compact size facilitates setup on a stand, table, or close to the musician, while the LED screen and backlit controls help maintain precision in challenging lighting conditions. Recallable scenes secure stage changes and allow quick retrieval of consistent settings from one show to another without starting from scratch.

ToneMatch + zEQ: Essential Equalization

The Bose ToneMatch processing provides an optimized tonal foundation based on the source (microphone, guitar, etc.), delivering a balanced sound without a lengthy correction phase. The zEQ function is designed to intuitively refine these presets: you adjust presence, body, and brightness with musical and immediately audible settings, which is handy when you need to quickly adapt to a venue or instrument change.

Per-Channel Processing: Dynamics and Effects at Your Fingertips

Each channel benefits from comprehensive tools to stabilize and enhance the signal: equalization, dynamic processing, and a selection of effects suitable for live contexts. You have access to compressor, limiter, de-esser, and noise gate to control level variations, clean vocals, tame dynamic guitars, or secure sensitive microphones. On the creative side, modulation effects (chorus, flanger, phaser, tremolo) and delays expand the sound and add depth without extra gear.

Reverb Management and Room Adaptation

The T4S includes a dedicated reverb on Aux 1 send, useful for shaping a comfortable monitor mix or specific ambiance while keeping the main mix clear. A global reverb can also be distributed across all channels to homogenize the overall sound. Finally, the main output equalization helps adjust the front-of-house to the room's acoustics, maintaining a balanced mix when the venue resonates, absorbs too much treble, or changes with the audience.

Stage Comfort: Tempo, Tuner, and Memories

To streamline a set, the T4S offers Tap Tempo (ideal for syncing delay to the song's tempo), an integrated chromatic tuner, and recallable scenes. USB type A/B connectivity facilitates playback and interfacing with PC/Mac according to your workflow, while the headphone output allows quick signal monitoring or silent preparation of settings. The magnetic cover protects the control surface during transport, and the mounting insert underneath the unit simplifies integration into a mobile setup.
