The Bose L1 Model 1S System with B2 Bass & T1 ToneMatch Audio Engine is a portable amplification system for musicians, DJs, and public speakers. It can be used to deliver up to 180° of horizontal sound coverage and features a smooth tonal balance for live stage, theater, rehearsals, and more.

The L1 Model 1S is built with a 12-speaker articulated line array and is compact and light enough to make setup quick and easy, yet powerful enough to fill a mid-sized venue. The B2 bass module offers more flexibility and even greater power at the low end. It enables you to use it as both a PA or a monitoring system, which can be positioned behind or beside the performer, enabling you to hear just what the audience hears.

Furthermore, the T1 ToneMatch Audio Engine is a digital multi-channel mixer designed for use with the Bose L1 sound system. The 4-channel engine features 100 ToneMatch presets for instruments and microphones, intelligent EQ, and a suite of studio-class effects and professional-quality processors.

In addition, the T1 ToneMatch is designed to enrich the sound of musicians using any Bose L1 system. The tone-shaping tools quickly bring you closer to the true sound of your voice and instruments, and helps you sound your best in live performances. It expands the input capacity of your L1 system and gives you access to a host of proprietary EQ presets, standard effects, and processors.
