L1 Model 1S with Single B1 Bass Package - Portable Line Array PA System

Product Description

The Bose L1 Model 1S with Single B1 Bass Package is a portable line array speaker system with a single bass module that is designed to serve as a PA and monitoring system for solo musicians and public speakers for audiences of up to 300 people.

Intended to be clean, compact, and not cluttered with connections, the L1 Model 1S system is equipped with a single line-level analog input via a 1/4" TRS jack. The analog line-level input has a trim control and a signal and clip LED. The input can be used to connect line-level instruments such as keyboards, or other line-level audio sources such as MP3 players or mixers for connecting microphones.

The L1 Model 1S system also includes a ToneMatch port for adding the optional T1 ToneMatch audio engine (available separately). The T1 ToneMatch adds mic inputs, additional line inputs, plus you can also use the ToneMatch effects engine to fine-tune your sound with Bose's proprietary tone-shaping tools.

The vertical configuration of the system's small, closely spaced drivers allows the L1 Model 1S system to deliver 180-degrees of horizontal sound coverage, yet at the same time only produce a small amount of vertical sound. This reduces unwanted reverberation and produces consistent tonal balance as the sound spreads more evenly across the stage and into the audience. Also, the volume level drops off less over distance than with a conventional speaker.

The L1 Model 1S upper array, the B1 Bass Module, and the power stand are designed to connect quickly and easily and do not require speaker stands. All components fit in to the included carry bags for storage and transport. The included B1 bass module is equipped with high-output, high-excursion drivers that are designed to produce deep, strong bass from a small enclosure. Designed for expandability, the L1 Model 1S system allows you to power up to two B1 bass modules, or one of Bose's more powerful B2 bass modules.
