Bose - L1® Model II system with B1 bass and ToneMatch® audio engine - Black

L1® Model II

Spatial Dispersion™ and Articulated Array® speaker technologies in the loudspeaker produce wide, uniform sound coverage.

The 24 small drivers are arranged using Articulated Array speaker technology in a slim, vertical enclosure - creating nearly 180 degrees of horizontal coverage and consistent tonal balance.

Integrated power amplifiers in the power stand provide clean, precise amplification for L1 Model II system with up to two B1 bass modules or one B2 bass module.

Analog input, trim control and signal/clip LED for line-level analog input via 1/4" TRS phone cable. Can be used for instruments or other audio sources like DJ mixers, MP3 players, computers or DVD systems.

Bass module out for amplified bass output signal to the bass module. L1 system automatically adjusts equalization appropriately when bass modules are connected.

Bass line out delivers post-DSP bass signal output. Accepts 1/4" TRS phone cable. Use to connect powered subwoofer, additional amplification system or Bose® PackLite® amplifier with up to two additional bass modules.

Two B1 bass modules

Compact, lightweight enclosure is easy to transport, set up and break down. Small footprint takes up considerably less space than traditional bass cabs. Interlocking feet let you securely stack up to four modules together.

Highly efficient speaker design features two 5.25" high-output, high-excursion drivers that produce deep bass from a small enclosure. When connected to power stand, active equalization circuitry automatically adjusts signal appropriately.

ToneMatch audio engine

Integrated ToneMatch technologies provide four independent channels featuring a library of ToneMatch instrument and microphone presets, proprietary zEQ and a complete suite of studio-class effects and sound processors.

ToneMatch presets optimize L1 to match intended natural sound of specific instruments and vocal mics. More than 100 presets are organized into quick-access banks and can be independently assigned to each channel. Free updates via USB.

zEQ automatically adjusts the range of tone controls to match your voice or instrument. zEQ appropriately redefines low-, mid- and high-frequency ranges of specified sources.

Single-band ParaEQ centers on the frequency you specify for each independent channel. Valuable tool for reshaping problematic frequencies in certain venues.

Five reverb types (small, medium, large, plate and cavern) available for global assignment, with individual channel controls for decay time, mix level and brightness.

Three delay types (analog/digital/tape) can be independently assigned to selected channels, with control over feedback time and mix level for each channel.

Ten modulation effects (three chorus types, two flange types, four phaser types and one vintage tremolo effect) can be independently assigned to selected channels, with control over designated parameters for each channel.

Seven dynamics processing types (three compressors, limiter, de-esser, kick gate and noise gate) can be assigned to independent channels.

Scenes allow you to store, recall and edit "snapshots" of all key ToneMatch audio engine settings at any given time. The engine includes five predefined Bose scenes, five My scenes and five Shared scenes you can give to other L1 owners.

Chromatic tuner for convenient tuning of instruments.

Large backlit display with intuitive layout and easy-to-read text for modes and settings.

Rotary encoder for quick access to modes, effects and parameters, including ToneMatch presets, zEQ, ParaEQ, reverbs, delays, modulators, dynamics processing, scenes and tuner. Features clean, circular layout.

Aux mode (channels 1 - 3) send channels' dry, pre-fader or post-fader audio to aux output for connection to additional L1 systems or recording devices. Independent level controls for optimal signal output.

Channel volume, mute and FX mute (1 - 4/5) for adjusting individual channel volume, muting individual channels and muting all effects on selected channels. Master volume adjusts overall level of master output.

Phantom power applies +48V power to input channels 1 - 3 to drive specific microphones. ToneMatch cable transfers audio signals and provides power to the ToneMatch audio engine from L1 power stand.

Mounting bar and carriage securely attach the ToneMatch audio engine to L1 loudspeaker. Cover and carrying case help protect the engine when storing and transporting.
