The L1 Model 1S with Two B1 Bass Modules from Bose is a portable line array speaker package that is designed to serve as a PA and monitoring system with extra bass response for solo musicians and public speakers for audiences of up to 300 people.
Intended to be clean and compact, the L1 Model 1S system is equipped with a single line-level analog input via 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. The optional T1 ToneMatch audio engine can be added if mic inputs are needed, or if more than one line input is needed.
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 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 two B1 Bass modules 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 two included B1 bass modules are each equipped with high-output, high-excursion drivers that are designed to produce deep, strong bass from a small enclosure. The L1 Model 1S system is capable of powering either the two included B1 modules or one of Bose's more powerful B2 bass modules (sold separately).
The L1 Model 1S system also includes a ToneMatch port for adding the optional T1 ToneMatch audio engine. 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.
