Unprecedented control with portability


Take control of your music with the T4S ToneMatch mixer, an ultra compact 4 channel interface designed for performers.

Sound great with integrated Bose ToneMatch processing and zEQ, especially when connected to a Bose L1 or F1 system for full end to end tonal control. Play confidently on stage with the rugged T4S using its tactile controls, easy to read LED display and scene recall. The T4S: a true performer's companion.


4-channel DSP Mixer with ToneMatch Digital Output

Add up to four mic/line channels and rich stereo DSP to your ToneMatch port-equipped Bose speaker system* with the Bose T4S ToneMatch Mixer from Guitar World. No external power is required — the T4S is powered by the ToneMatch port and included EtherCon cable.

As a mixer, the 4-channel T4S is beautifully laid out, with dedicated knobs for levels, mutes, and ToneMatch presets rather than endless menus — which makes it great for performers coming from an analog mixer environment. But the real magic behind the T4S lies in its ToneMatch technology and no-compromises DSP. Just tell the mixer which microphone you're using or what kind of guitar you have plugged into it, and the T4S optimizes sound for you on the spot. Performers can further customize their tone using channel-independent compressors, gates, EQs, and even a tap-tempo delay.


Hundreds of sonic refinements — instantly

The ToneMatch audio engine puts Bose's largest library of customized presets at your command. These ToneMatch presets instantly optimize instruments at the touch of a button. Different presets can be independently assigned to each of the engine's four channels. For example, select exact mic presets for the microphones you're using on channels 1 and 2, your guitar model for channel 3, and your bass model for channel 4 — all at the same time. Bose's engineers often work with manufacturers directly to expand the ToneMatch preset library, and updates are available to you free with easy downloading via the built-in USB port.

Intelligent EQ and effects

Fine-tune your sound system with greater accuracy using Bose's intelligent zEQ system. It redefines low, mid, and high ranges for each ToneMatch preset. When you need to cut or boost specific frequency ranges for different instruments and mics, zEQ gives you the power. Globally assign one of five different reverbs to each mic/line channel. You can also choose from three delay types, 10 additional effects, and seven dynamics processors — and assign them independently to each channel. Additionally, the T4S's 6-band master EQ helps compensate for venue acoustics.

Magnetic mixer cover

For protection and peace of mind, the T4S ToneMatch Mixer includes a magnetic cover. This feature both preserves levels from gig to gig and protects your T4S from damage on the road or at the show.

Bose T4S and T8S: which mixer is right for me?

The biggest differences between these mixers are the number of onboard channels and the ways in which they interface with your sound system. Don't hesitate to reach out to your Guitar World Sales Engineer with further questions.
