The Bose L1 Model 1S with Double B1 Bass Package is a portable line array speaker system with two bass modules 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 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 included B1 bass modules are equipped with high-output, high-excursion drivers that are designed to produce deep, strong bass from a small enclosure.
Bose L1 Model 1S Cylindrical Radiator Loudspeaker Array
The Bose L1 Model 1S Cylindrical Radiator Loudspeaker Array provides 180 x 10° nominal dispersion and consistent front-to-back coverage well suited for production and reproduction of live music, music playback, speeches, and A/V sound reproduction.
Bose L1 Model 1S Power Stand (120V)
The 120V Bose L1 Model 1S Power Stand is the central hub for the L1 Model 1S portable line array system. The power stand provides the connectors for power, bass module output, 1/4" analog input, power & signal indicators, and the ToneMatch port for the optional T1 ToneMatch audio engine, as well as the top array and bottom extension.
Bose B1 Bass Module
The Bose B1 Bass Module is a passive low-frequency, portable speaker intended for use with the Bose L1 Model I & Model II Systems. The speaker enhances the low-frequency response, adding depth and bass to musical instruments, DJ rigs and other sound reinforcement applications. The B1 may be connected to the power stand of the L1 Model I and L1 Model II, or use the optional A1 amplifier to provide added power to a pair of B1 speakers.
