The Bose T1 ToneMatch Audio Engine is a powerful multichannel sound tool for the Bose L1 systems, with controls so advanced they adapt to you and your instrument. Four-channel engine features proprietary ToneMatch presets, intelligent zEQ and a large suite of professional-quality effects and processors.

Its powerful features and tone-shaping tools quickly bring you closer to the true sound of your voice and instruments. This versatile digital mixer helps you sound your best in live performances. It expands the input capacity of your L1 system and gives you instant access to a host of proprietary EQ presets, standard effects and processors.

The ToneMatch audio engine puts our largest library of customized presets at your command. These ToneMatch presets instantly optimize instruments and microphones for any L1 system, all at the touch of a button.

Different presets can be independently assigned to the engine's four channels. For example, select Audix® OM5 mic presets for channels 1 and 2, Taylor® guitar for channel 3 and Lakland® bass for channel 4—all at the same time.

Our engineers often work with manufacturers directly to expand the ToneMatch preset library. Updates are available to you free, with easy downloading via the engine's USB port.

Fine-tune your sound system with greater accuracy. Bose intelligent zEQ 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, ten additional effects, and seven dynamics processors—and assign them independently to each channel.

Store your customized settings for specific gigs with the Scenes feature. The engine comes with five predefined Bose scenes and ten you can define. Fast, one-touch scene recall helps you make quick work of repeat setups.

Simply link the engine to a Bose L1 Model 1S or Model II system via the included digital cable—and rev it up. A sleek bracket is also included to attach the engine to the loudspeaker. When connecting the T1 ToneMatch audio engine to an L1 Compact or Model I system, an analog cable and a T1 power supply are required.
