The Technology

What is the T1 ToneMatch™ audio engine?

The T1 ToneMatch™ audio engine is Bose’s powerful multi-channel audio device designed for musicians for use with L1™ Model I and Model II systems, containing our largest library of ToneMatch™ presets, proprietary zEQ, and a complete suite of studio-class effects and processing.

The T1 was carefully designed with the needs of the musicians in mind. This makes for a completely integrated and powerful unit that is easy to use, and it alleviates many challenges associated with live performances.

What are ToneMatch presets, and what are their benefits?

ToneMatch presets are designed for specific instruments and microphones for use with the L1 Model I and Model II systems. 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 new 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 benefit of the ToneMatch™ port on the T1?

When used with a ToneMatch™ cable, it connects the output of the T1 to the Model II power stands ToneMatch port. It also delivers power to the T1 from the Model II power stand. The user may enjoy the benefits of digital quality audio while alleviating the need for an additional power supply and excessive wiring when used with the L1 Model II system.

What is the proper method for setting the gain on the L1™ Model II power stand when connected to a T1 ToneMatch audio engine?

Adjust output volume of source to normal operating volume. Make sure that the Master volume and the channel volume on the T1 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 T1 clockwise until the signal/clip indicator glows green or yellow. If the indicator flashes red or glows steady red, turn the trim control counterclockwise to decrease the level.

What are the preamp outputs on channels 1-3?

Direct dry output signal that may be connected to other amplifiers or recording devices. Preamp outputs for channels 1-3 accept a 1/4" TRS balanced phone plug cable.

Functionality

How many inputs does the T1 ToneMatch audio engine have, and what type are they?

Inputs 1-3 are analog input channels with a combination input connector. This connector supports either balanced XLR audio cables or 1/4" TS unbalanced phone plug cables. Easily connect multiple sources with the added flexibility of accepting either balanced XLR audio cables or 1/4" TS unbalanced phone plug cables.

Analog input channels 4/5 accept a 1/4" TRS balanced phone plug cable. Both inputs are affected by a common channel edit control. These stereo inputs are useful for connecting the outputs from PC soundcards, mixing consoles and digital keyboards.

How can you verify the version of ToneMatch presets that are on the T1?

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 T1 with new ToneMatch presets?

The T1 is equipped with a USB interface that may be connected to a PC. Check www.Bose.com/musicians for periodic updates on preset availability.

What is a Bose® scene?

The T1 contains five Bose® scenes, which contain specific default processing configurations for various applications intended as a starting point in achieving great sound. The Bose scenes are Factory settings, Singer/songwriter, DJ/playback, Drums and bass, and Electric works.

Bose Scene 01 – Factory settings

This scene restores the T1 audio engine to the settings it had when it left the factory. Loading this scene erases any changes you previously made.

Bose Scene 02 – Singer/songwriter

Bose Scene 02 is designed for singer/songwriter playing keyboard or guitar and sometimes accompanied by an MP3 track.

Bose Scene 03 – DJ/playback

Bose Scene 03 is designed for a DJ event or any audio playback need. This setup uses two microphones and either an MP3 player, mixer or laptop PC.

Bose Scene 04 – Drums and bass

Bose Scene 04 is set up for a bass guitar, kick drum, and either an MP3 player or laptop PC.

Bose Scene 05 – Electric works

Bose Scene 05 is designed for electric and acoustic guitars, bass guitar and keyboard.

What is a user-defined scene?

The T1 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 at a later time. This greatly reduces the amount of configuration required.

What is a shared scene?

A shared scene is a bank of five scenes that you can send out of the T1 to a PC when using the L1™ updater software. This allows you to share scenes with other members of the user community. To obtain software, please go to www.Bose.com/musicians.

Does the T1 ToneMatch™ audio engine have built-in effects? What are some of the features and applications where they may be used?

Yes. Below is a list of effects that users may ===independently === assign/adjust for ===any or all === channels. The user also enjoys discrete control over designated parameters for each respective channel.

Compressor 3: Heavy

Compressor featuring a preset high compression ratio with variable threshold and gain parameters and may be used with loud instruments such as horns and drums, vocals or other instruments that require more aggressive level control.

Noise gate

adjustable threshold and speed independently assignable for each channel. Controls extraneous noise from open microphones or hot instrument pickups from being introduced into the system.

Limiter

User-adjustable threshold and gain settings are independently assignable for each channel.

Prevents input signals from overloading, helping to maintain consistent gain staging.

De-Esser

User-adjustable threshold and gain settings are independently assignable for each channel.

Compression useful in reducing high-end frequencies associated with vocal sibilant sounds.

Kick Gate

regular and fast gate types with user-adjustable threshold and tight settings that are independently assignable to each channel. Add punch or tightness to achieve desired kick-drum level.

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 mode on the T1 allows you to send selected input channels to the Aux output. By accessing the Aux mode via the mode selector, you then have the ability to determine if the signal will be Dry (after preamp), Pre (includes EQ and FX) or Post (after fader).

Applications

Does the T1 have amp modeling capability?

No. Distortion must be produced first and then fed into the T1 as a clean, non-clipping signal. To achieve distortion, the guitarist can use a few methods:

- Inline devices: One popular method would be to use any of the effects pedals on the market or use a DSP-based amplifier modeler, such as the Line 6 "Pod" that models the tone produced by amplifier tubes, guitar transducers and guitar amplifier speaker cabinets.

- Miking a guitar amplifier: Another method would be to use a guitar amplifier, and mic the speaker as closely as possible. The trick here is to run the amplifier at the lowest level at which the correct tone is attainable but does not diminish the benefits of the L1™ Model II system. Louder amplifiers can be located and miked offstage. Miking small, low-watt amplifiers is a better technique for this method.

- Use a loading device. Some electric guitarists may prefer to use their amplifier’s output as an input signal into the power stand. Before doing this, they must use a load device, such as a "Plate Soak" or a "Hot Plate" to give a line-level output suitable for the input stage of the T1.

- Use the "line output" of a guitar amplifier. Some amplifiers have this option, and it may be suitable for some guitarists. The only suggestion here is to turn the volume of the amplifier down so only the L1™ Model II system is heard.

Refer to the Bose® website and Musicians Community Forum at www.Bose.com/musicians to learn how to interface additional instruments with the system.

General (Product)

I own an L1™ Model I system. Can I purchase the T1 separately and use it with the system?

Yes. The T1 is available for purchase separately and may be used with either an L1™ Model I or Model II system. When used with a Model II system, the audio is connected digitally via the ToneMatch™ ports. When used with a Model I, a separate power supply is required to power the T1, and the audio is analog. When using with a Model I, simply connect the T1’s Master Output jack to the analog input of Channel 3 or 4 on the Model I power stand. The T1 power supply is available through Bose or authorized dealers of the L1 family of products.

Can the T1 be used as a stand-alone mixer?

Yes. However, many of the advantages that the L1 family of products provide, such as even sound dispersion and portability, are not realized when the T1 is used with conventional speaker systems.

There is a buzz in the system. Any suggestions on how to fix it?

Noise and buzzing is a typical problem with pro audio gear. The new Bose® approach is very much immune to noise because it is a simple, independent system. The typical buzzes and hums associated with ground loops are gone when you use an independent system that is not interconnected electronically to other pieces of equipment. Some equipment could still be connected to the Bose system. This is not a comprehensive guide to noise troubleshooting but will offer a suggestion. One of the most important suggestions to alleviate buzz and hum in a system is to plug all interconnected gear into the same electrical circuit. Guitar players or vocalists with effects should plug those units into the same electrical outlet as their power stand. This normally fixes all problems. Do not use 3- prong to 2-prong adapters, also known as ’cheaters’ or ’ground lifters’. This is a serious safety threat, which bypasses a safety grounding mechanism.

Can I use this 120-volt system in another country?

No. The unit does not have a universal power supply; use the 120V version only in 120V countries. Use the 240V version in countries with 220,230 or 240V systems at 50Hz. We do not have a 100V.
