High-Density Connectivity: 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 1/4-inch TRS analog outputs.

Convenient Gig-Ready Features: Rugged and ready to go, the T4S includes a protective magnetic cover and a ToneMatch cable for connecting directly to a Bose L1 PRO system, providing a convenient single-cable connection for digital audio and power. A bottom insert allows you to use standard mounting accessories to keep the T4S within reach.

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.

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.

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.

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.

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 1/4-inch TRS balanced cables.

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 1/4-inch balanced (TRS) or unbalanced (TS) cables. Easily connect multiple sources with the added flexibility of accepting either balanced XLR audio cables or 1/4-inch balanced or unbalanced cables. Aux input channels 5 & 6 (9 & 10, T8S only) accept a 1/4-inch 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.

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.

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.

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.

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.
