For its size, the stereo T4S mixer gives you unprecedented connectivity with control. Four main channels feature high-quality audio preamps with XLR-combo jacks for microphones or instruments, and switchable phantom power. Additionally, the T4S offers two aux sends, two aux inputs, stereo balanced outputs, two ToneMatch outputs for digital audio (with remote power), USB-A and -B for USB drive playback or PC/Mac interfacing, a dedicated headphone jack, and balanced ¼” TRS analog outputs.
Convenient Gig-Ready Features

A bottom insert allows you to use standard mounting accessories to keep the T4S within reach.
What are the differences between the T4S and the T8S?
The T4S and the T8S both have the same compact interface, tactile knobs and advanced digital audio processing, yet the T8S gives you an expanded channel count with four more mic/line inputs and a total of four Aux sends. The T8S also includes an output meter to visually monitor your output level. The T4S can receive power and send digital audio to a Bose L1 PRO System when using the included ToneMatch cable. The T8S comes standard with a universal power supply and does not offer a ToneMatch link.
What are ToneMatch presets, and what are their benefits?
ToneMatch presets are designed for specific instruments and microphones for use with the Bose L1 PRO Systems, S1 Pro or F1 system. ToneMatch presets are available for each channel and instantly bring you closer to the true sound of your voice or instrument—all at the touch of a button. When you select a proprietary ToneMatch preset for your microphone or instrument, you are tapping into a powerful technology, available only from Bose.
What is the concept behind zEQ, and what are the benefits?
Ordinary tone controls are generic by design: “High,” “Mid” and “Low” controls are spread out across the entire musical spectrum. Proprietary zEQ automatically shifts the range of these controls so that they correspond directly to the range of your voice or instrument. zEQ gives you more precise control over your tone, making it easy to fine-tune your sound.
What is the proper method for setting the gain on the T4S/T8S ToneMatch mixer?
Adjust the output volume of the source instrument to normal operating volume, or sing into the microphone using your loudest level. Make sure that the Master volume and the channel volume on the T4S/T8S are set to 0. While playing your instrument/audio sources as loudly as you would during a performance, turn the Trim control on applicable channel of the T4S/T8S clockwise until the signal/clip indicator glows green. If the indicator flashes red or glows steady red, turn the trim control counterclockwise to decrease the level until it’s most always green.
What are the two Aux outs on the T4S and 4 Aux outs on the T8S?
These are direct output signals that can be taken pre or post mix and connected to a number of different devices including personal monitors, amplifiers or recording devices. Aux outputs accept ¼” TRS balanced cables.
How many inputs does the T4S/T8S ToneMatch mixer have, and what type are they?
Inputs 1-4 (1-8 with the T8S) are analog inputs channels with a combination input connector. This connector supports either balanced XLR audio cables or ¼” balanced (TRS) or unbalanced (TS) cables. Easily connect multiple sources with the added flexibility of accepting either balanced XLR audio cables or ¼” balanced or unbalanced cables.
Aux input channels 5&6 (9&10 T8S only) accept a ¼” balanced or unbalanced cable. Both inputs are independent of each other and can have separate volumes and pans. These stereo inputs are useful for connecting the outputs from PC audio interfaces, mixing consoles and keyboards/synths.
How can you verify the version of ToneMatch presets that are on the T4S/T8S?
Access the global preferences menu to confirm which interchangeable ToneMatch preset banks are loaded on the system. Use the rotary encoder to select the global Prefs mode. Press Menu button to select menu list, then rotate the Select button to scroll through the list and highlight the ToneMatch description.
What is the process for updating the T4S/T8S with new ToneMatch presets?
The T4S/T8S is equipped with a USB interface that may be connected to a PC. Check the product webpage for the T4S/T8S for periodic updates on preset availability.
What is a Bose scene?
The T4S/T8S contains five Bose scenes each, which have specific default processing configurations for various applications intended as a starting point in achieving great sound. The T4S Bose scenes are Singer/songwriter, DJ/playback, Drums and bass, Electric works and Factory settings. The T8S Bose scenes are Full Band, String Band, Stereo DJ, Electronic and Factory settings.

What is a user-defined scene?
The T4S/T8S allows the user to easily store, recall and edit performance scenes (a snapshot of the complete state of the unit) into five user-defined scenes. User-defined scenes help achieve consistent sound with minimal configuration. After editing a Bose scene to your preference, you may re-save it as a user-defined scene, allowing you to easily recall it later. This greatly reduces the amount of configuration required.
What is a shared scene?
A shared scene is a single user scene that you can send out of the T4S/T8S to a PC when using the ToneMatch updater software. This allows you to share the scene with other members of the user community. To obtain software, please go to the product webpage for the T4S/T8S.
Can you assign multiple effects to any or all channels?
Yes. The user may run multiple effects on one channel while simultaneously running a set of completely different effects on each of the other channels. Each effect type has designated user-adjustable parameters, which also may vary from channel to channel.
Can I create a sub mix to send to a house PA system or recording device?
Yes. The Aux outputs on the T4S/T8S allow you to send selected input channels to separate mixes by accessing the Aux menu under PAN/AUX. You then can determine if the signal will be Dry (after preamp), Pre (includes EQ and FX) or Post (after fader).
Does the T4S/T8S have amp modeling capability?
Refer to the owner’s guide on the product webpage for the T4S/T8S for more information on interfacing instruments with the ToneMatch mixers.
Can I purchase the T4S/T8S and use it with other Bose systems?
Yes. The T4S/T8S is available for purchase separately and may be used with a Bose L1 PRO System, S1 Pro or F1 system. When a ToneMatch mixer is connected to one of these systems, ToneMatch processing delivers an optimized experience. ToneMatch mixers can also be used with non-Bose PA systems by using analog connections and an external ToneMatch power supply (ships only with the T8S model).
