Controls and effects

Individual channel controls include input trim, a signal indicator/clip light, output level, mute, and FX mute. Digital signal processing gets applied channel-by-channel or globally onto the output channels. You can apply and adjust parametric equalizers, noise gates, limiters, compressors, reverbs, delays, and more. Bose includes their ToneMatch and zEQ presets, for quickly dialing in the sound for voice and acoustic guitar. There's even a built-in tuner, so guitarists can stay in tune.

Bose L1 PA connection

The T4S mixer does not come with its own power supply. The T4S was designed to work with a Bose L1 Model 1S or Model II loudspeaker system, getting its power through the ToneMatch cable that comes with the mixer. That cable can also serve as a digital signal connection between the mixer and an L1 system. You can use a T4S without an L1, by getting the optional ToneMatch power supply (available soon).

Features

Overview: The Bose T4S ToneMatch mixer is an ultra-compact 4 channel digital mixer designed for live performances such a singer/songwriters, mobile DJs, corporate A/V, and more. Its powerful DSP engine offers studio-quality EQ, dynamics, and effects for each input channel, along with Bose's unique ToneMatch processing presets. The T4S also offers direct integration with Bose L1 speaker systems for full end-to-end tonal control.  

Inputs & Outputs

Inputs: The T4S' rear panel includes the following inputs:

  • Inputs 1-4: These consist of 4 XLR/1/4" combination jacks that can accept either low impedance balanced/unbalanced connections for microphones or 1/4" TRS balanced/TS unbalanced for high-impedance devices like guitars.
  • Aux In (5/6): Two additional 1/4" input jacks are provided as an Auxiliary Input. These can accept line-level signals, either TRS balanced or TS unbalanced, from sources like an audio playback device. Signals coming in on the Aux Input are mixed directly to the Main Output. Controls for the Aux In include Pan and Level, which are configured in the Menu system.
  • USB Ports:
    • USB 2.0 Type-A: Can be used for playing back music from a flash drive. Supported audio files include WAV and MP3.
    • USB 2.0 Type-B: Allows you to connect the mixer to your computer for storing and recalling performance scenes as well as for installing firmware updates. When connected to a computer, this can also be used for audio playback and recording. 

Outputs: The T4S' rear panel includes the following outputs:

  • Analog L/R Output: Two 1/4" jacks provide the main analog output for the T4S, accepting both TRS balanced or TS unbalanced cables.
  • Aux Output: Two user-assignable jacks are provided that can be configured for pre-fader, post-EQ and effects, or post-fader outputs. These 1/4" jacks can accept both TRS balanced and TS unbalanced connections. 
  • ToneMatch Outputs: The T4S mixer features two proprietary ToneMatch (RJ-45) connections that provide both left and right digital audio outputs, for use with an optional Bose L1 Model 1S, L1 Model II (B1), or L1 Model II (B2) Power Stand speaker system (sold separately). When connecting the T4S with one Power Stand speaker system, using the supplied ToneMatch cable, the T4S gets connected to the right ToneMatch output, which will provide a mono signal. When using it with two Power Stand speaker systems, each output is connected to one Power Stand for stereo sound. The connected L1 speaker system will also provide power for the T4S through the right ToneMatch port. If using the T4S with other sound systems, it can be powered using the optional ToneMatch power supply (sold separately).

Note: A standard RJ-45 ethernet cable should never be plugged into the ToneMatch ports. These connections provide power along with audio data and will damage equipment such as a computer, router, or other network device.

  • Headphones: The right side-panel includes a 1/4" headphone output jack.

Controls

Front Panel: All of the T4S' controls are located on the front panel and include the following parameters:

  • Display: The front-panel LCD screen displays all setup and control parameters.
  • Input Signal/Clip LEDs: Input channel LEDs will light green when a signal is applied to that input and light red if the signal starts to clip.
  • Trim Controls: Adjusts the input sensitivity for the respective channel.
  • CH Edit Buttons: These allow you to select which input channel will can be edited. Editing parameters are displayed on the LCD screen.
  • Editing Controls: Three rotary/push-button controls let you select or adjust parameters appearing on the display.
  • FX Mute: These buttons allow you to quickly mute any effects that have been applied to that channel.
  • Volume: Individual Volume dials are provided for each channel.
  • Mute: Each input channel includes its own Mute button.
  • Phantom Power Switch: When activated, this parameter applies +48V of phantom power to each of the input channels.
  • Master Volume: Adjusts the overall output level.
  • Headphone Volume: Adjust the output level of the headphone jack.
  • Rotary Selector: Provides access to both Global and Channel Functions (further details below).

Functions

Overview: All of the main functions of the T4S mixer are accessed using a front-panel Rotary Selector. Options are divided into to groups; Channel Functions, parameters that are applied individually to input channels, and Global Functions, which pertain to the overall function of the mixer.

Channel Functions (Rotary Selector): Channel Functions include audio parameters that can be selected and modified using the Rotary Selector and Rotary/pushbutton controls. These can be individually applied to each input channel. Nine Channel Edit parameters are available including:

  • Pan/Aux: Allows you to adjust the panning of that channel's input signal. Also gives options for setting the Pan and Level for the Aux In, and Aux Out signals.
  • Tuner: Provides a tuning meter for an instrument playing into the selected channel. The note being played will be displayed at the bottom of the screen, while a pitch indicator scale will show whether the note is sharp or flat.
  • ToneMatch: Accesses the T4S' ToneMatch presets. This proprietary technology provides optimized system equalization for specific instruments and microphones. ToneMatch presets are organized into categories, such as Vocal Mics, Headworn Mics, Acoustic Guitars, Electric Guitars, etc. A ToneMatch preset can be individually applied to each input channel.
  • zEQ: Working in conjunction with the ToneMatch presets, the zEQ allows you to adjust Low/Mid/High frequencies that are within the range of the instrument or microphone, based on the ToneMatch preset selected. Each of the individual zEQ frequency bands, for that particular ToneMatch preset, can be bypassed as well.
  • Para EQ: Provides 3 bands of parametric equalization to that channel. Each of the 3 bands are user-selectable between 50Hz and 16kHz, and include a Level control that can raise or lower that frequency by +15dB to -15dB. The width of the band, or Q, can be adjusted with a range from 0.20 octaves to 5.0 octaves.
  • Comp/Gate: This function provides access to the dynamics presets such as Gate, Compression, Limiter, De-esser, and Kick Drum presets, all with adjustable parameters.
    • Compressor: Three levels of compression are available; Light, Medium, and Heavy, for a range of uses from instruments and mics that require minimal level control to loud instruments and strong vocals that require more aggressive level control. Compression ratios are preset for each type with user-adjustable Threshold and Speed (release time).
    • Limiter: This preset features hard-limiting with a ratio of ∞:1 and adjustable threshold and gain. Limiting helps prevent signal peaks from overloading the channel.
    • De-esser: Designed to reduce sibilance on vocals.
    • Noise Gate: Helps eliminate unwanted noise from microphones and instruments. Features a fast attack time, variable threshold, and variable speed (release).
    • KickGate1 (Regular): This gate is designed specifically for kick drums and features a preset attack time with variable threshold and tightness (release time). This provides maximum gain before feedback, making kick drums as loud as possible.
    • KickGate2 (Fast): This preset works the same as KickGate1, but adjusted for faster tempos, and works well when using a double bass drum pedal.
  • Mod: Provides access to Modulation effects such as Chorus, Flanger, Phaser, and Tremolo.
    • Chorus: Three different types of chorus are provided; Brite, Warm, and Dark, each allowing varying amounts of high frequencies in the channel signal to pass. User-adjustable parameters include Mix, Depth, and Speed.
    • Flanger: Two types of flanger presets are available; Tape, which features no signal feedback, and Feedback, which does include signal feedback. Both types include adjustable Mix, Depth, and Speed parameters.
    • Phaser: Four phaser are available; Stomp, modeled after a classic "stompbox"-style phaser; Rack, modeled after a classic "rack"-style phaser; Warm, vintage-style phaser with a positive mix type; and Brite, featuring a positive mix type with no bass. Each Phaser preset includes adjustable Speed and Feedback parameters.
    • Tremolo: This is a vintage-style tremolo effect with adjustable Speed and Depth.
  • Delay: Three types of delays are provided; Digital, Analog, and Tape, with each having adjustments for the Mix, Time, and Feedback.
    • Digital Delay: In this delay type, the feedback repeats remain uncolored.
    • Analog Delay: Feedback repeats continuously deteriorate.
    • Tape Delay: Feedback repeats deteriorate even more than with the Analog Delay.
  • Reverb: This function lets you apply an adjustable amount of reverb to the selected channel. Adjustable parameters include; Mix, and Bright. Bright controls the level of high-frequencies in the effected signal. The type of reverb, along with its settings, are selected in the Global menu.

Global Functions (Rotary Selector): The Global Functions selection gives you access to settings that affect the overall operation of the mixer and include; Reverb Type, Prefs (Preferences), and Scenes.

  • Reverb Type: This Global option lets you select one of five reverb types that can be applied to both individual channels as well as directly to the Main or Aux outputs. The Main and Aux can have a different reverb type if desired. Each type features adjustable Time and Balance parameters. Reverb Types include; Plate, Small, Medium, Large, and Cavern.
  • Prefs (Preferences): This setting gives access to several system utilities options.
    • Status: Displays the effects and dynamics used on each of the 4 Input Channels (non-editable).
    • Input Level: Displays input level meters for each of the 4 Input Channels with peak signal indicators for each.
    • Output Level: Displays output level meters for all outputs including: Main L, Main R, USB L, and USB R.
    • Master Out EQ: Displays a 6-band graphic EQ that gets applied to the master mix output. Each band can be raised/lowered by 18dB.
    • USB B to PC: This selection allows you to send a selected source to a computer through the USB left and right output channels. Source choices include Ch.1-4, Aux In, Master, or Aux Out 1-2.
    • USB B from PC: This selection allows you to send USB left/right channels from a computer to a selected mixer destination; None, Aux In, or Master.
    • USB A Playback: This selection lets you play WAV or MP3 files, stored on a flash drive, from the USB A port. Files can be viewed/selected as well as have the level adjusted.
    • Versions: Displays firmware version.
    • ToneMatch: Displays a list of ToneMatch preset banks stored in the mixer.
    • L1 Power Stand: When connected to an L1 Model 1S/II Power Stand, "connected" appears on the display.
  • Scenes: A Scene is a snapshot of the current state of the mixer, that can be saved and recalled at a later time. It saves all ToneMatch mixer settings and the status of the front-panel Mute, FX Mute, and CH Edit buttons. A Scene does not store Channel Trim, Channel Volume Levels, Master Volume, Headphone Level, or the position of the Phantom Power switch. The T4S includes 16 Scenes, which are divided into 3 types:
    • Bose Scenes (5): These are read-only factory presets that cannot be edited or overwritten.
    • User Scenes (10): These are user-definable scenes that can be saved and recalled as many times as you like.
    • Shared Scenes (1): This is a user-definable scene that can be shared with other T4S and T8S ToneMatch mixers.
