The Bose L1 Model I Single Bass Package delivers the audio fidelity expected from Bose in a sleek, lightweight and portable unit that's ideally suited for musicians, mobile DJs, and performances, and other sound reinforcement applications. The L1 Model I Single Bass Package features a 4-channel mixer amplifier that also serves as the speaker's base. The mixer features two mic/line input channels (1 and 2) that accept XLR and ¼" TRS connections. Line inputs are featured on channels 3 and 4. Also included is the Bose B1 Bass module for reinforcing low-end frequencies and enhancing the sound of bass guitar, DJ rigs and more.
The ultra-low noise preamps provide high signal to noise ratio, and Bose's Proprietary ToneMatch presets on channels 1 and 2 optimize the L1 system to match the intended natural sound of specific instruments and microphones. The speaker features 24 small drivers, carefully positioned to ensure balanced audio signal at the direct and off-axis (sides) of the system. Setting up the L1 Model I is quick and easy; simply place the speaker extensions into the amplifier base, and slide the speaker on top of the extensions. Two extensions are included, and allow easy height adjustment.
