Proprietary ToneMatch Presets
ToneMatch presets on channels 1 and 2 optimize L1 system to match intended natural sound of specific instruments and microphones.
Cylindrical Radiator Loudspeaker
Uses 24 small drivers mounted into a slim, vertical enclosure to create nearly 180 degrees of horizontal coverage-with little dropoff in volume and tone. Loudspeaker's two-piece, interlocking design makes for quick and easy setup, breakdown and transport.
Integrated Power Amplifiers
Integrated power amplifiers in the power stand deliver clean, precise amplification for L1 Model I loudspeaker and up to two B1 bass modules.
Channel Inserts/Effects Loops
Connect external effects and processors to channels 1 and 2 via ¼" TRS line input/output jack. Use a stereo plug to connect the send and return signals with one cord.
Bass Module Out
For amplified bass output signal to one or two B1 bass modules. 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.
Digital Data Out
Sends digital mix of channels 1 and 2 to external recording gear at 48KHz sample rate.
Digital Data In
For updating product firmware and ToneMatch presets.
R1 Remote Input

Remote
Tone Controls
Provide -12 dB cut to +12 dB boost of high, mid and low frequencies on channels 1 and 2.
Level Controls and Signal/Overload LEDs
Green/red signal status to help you set proper gain levels.
Master Level
Adjusts volume of all four input channels simultaneously.
Bass Module
Compact, lightweight 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 feet let you securely stack up to four modules together on their sides.
Highly efficient speaker design features two 5.25" (13.3 cm), high-output, high-excursion drivers that produce deep, strong bass from a small enclosure. When connected to power stand, active equalization circuitry automatically adjusts bass signal appropriately.
