Boost your performance with the L1 Model II system, our most advanced portable amplification system for musicians, DJs and public speakers. The loudspeaker delivers 180 degrees of horizontal sound coverage and our smoothest tonal balance—across the stage and throughout the room. And the ToneMatch audio engine provides a suite of studio-class effects and tone-shaping tools to give you just the sound you’re looking for. Includes one B2 bass module for more flexibility and even greater power at the low end.

Our best portable sound system for musicians combines the Bose L1 Model II system and T1 ToneMatch audio engine. This professional concert sound system provides wide coverage, smooth tonal balance and a suite of studio-class effects and tone-shaping tools. And it’s packed with proprietary Bose technologies designed to improve your amplified sound.

Sound advantages—only from Bose

Like the original, award-winning Bose L1 loudspeaker system, this Model II sound system is an all-in-one innovation that replaces conventional monitors, mixers and PA speakers. The system’s breakthrough loudspeaker produces wide, uniform sound coverage of nearly 180 degrees—onstage and throughout an audience of up to several hundred—with little dropoff in volume and tone.

The Model II system also features Articulated Array speaker technology for better tonal balance. The loudspeaker’s 24 vertically mounted drivers are precisely angled to create clearer highs and more consistent tone in the room. Even people off to the sides of these stage speakers enjoy well-balanced, detailed sound.

Powerful multichannel audio engine

Combining the T1 ToneMatch audio engine with your L1 system expands your options to connect additional instruments and microphones. You can also use the ToneMatch engine to fine-tune your sound with powerful, proprietary tone-shaping tools.

The compact, four-channel engine provides fingertip control of a library of ToneMatch presets. Just touch a button to make hundreds of precise refinements to the sound of instruments and microphones. The engine also features a complete suite of studio-class reverbs, additional effects and dynamics processing. It connects to the L1 Model II system via a single digital cable for quick, streamlined setup.

Full, flexible bass

The high-performance B2 bass module delivers greater low-frequency output when you need more powerful bass for larger audiences. The module includes three settings for increased flexibility. The normal setting is ideal for bass guitar or when miking a kick drum. A higher setting is designed for DJ/music playback applications. And the lower setting works well for acoustic guitar and vocals.

You can power one B2 bass module on a single L1 power stand. And the optional PackLite power amplifier lets you add a second B2 bass module for maximum low-end power.

Easy and efficient

The L1 Model II power stand weighs only 24 pounds, and its four retractable legs make it easy to transport and set up. The power stand also has a simplified control section; the single line-level input can be used with instruments, mics, mixers, laptops, MP3 players or DVD systems.

All of the system’s components are also built to handle the road. The loudspeaker has a rugged, reinforced grille, and each package includes padded carrying bags for major components.

Features

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.
ToneMatch port on power stand for digital audio and power connection to ToneMatch audio engine.
Analog input, trim control and signal/clip LED for line-level analog input via ¼” 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 one or two B1 bass modules or one B2 bass module. L1 system automatically adjusts equalization appropriately when bass modules are connected.
Bass line out delivers post-DSP bass signal output. Accepts ¼” TRS phone cable. Use to connect powered subwoofer, additional amplification system or Bose PackLite amplifier with up to two additional bass modules.
Retractable legs provide stability for streamlined power stands and loudspeakers. Four retractable legs fold out of power stand simultaneously for quick setup and compact transport

B2 bass module

Compact enclosure is easy to transport, set up and break down. Small footprint takes up considerably less space than traditional bass cabs required for same performance. Interlocking end caps let you securely stack two modules together on their sides.
Highly efficient speaker design features two 10″ (13.3 cm), high-output, high-excursion drivers that produce deep, strong bass from a small enclosure. Three level settings provide flexibility of output. When connected to power stand, active equalization circuitry automatically adjusts bass signal appropriately.

ToneMatch audio engine

Integrated ToneMatch audio engine and audio 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.
Proprietary ToneMatch presets optimize L1 system 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 ongoing updates via USB connection between your computer and ToneMatch audio engine.
Proprietary zEQ automatically adjusts the range of tone controls to match your voice or instrument, making it easier to fine tune your sound. Conventional mixers may have fixed EQ ranges that don’t accurately affect desired frequencies when adjusted. But zEQ appropriately redefines low, mid and high frequency ranges of specified sources.
Single-band ParaEQ centers on 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 and tape) can be independently assigned to selected channels, with control over feedback time and mix level for each channel. For example, you can select tape delay for your vocal on channel 1 and analog delay for your guitar on channel 2.
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. This feature helps simplify setup when you’re using an L1 system repeatedly in different venues. 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 ToneMatch audio engine from L1 power stand.
Mounting bar and carriage securely attaches ToneMatch audio engine to L1 loudspeaker.
Cover and carrying case help protect engine when storing and transporting.
