VLSL 3001	Single Pendant VoiceLift Lite System	42-380-01
VLSL 3002H	Pendant and Handheld VoiceLift Lite System	42-380-03

The Extron VoiceLift® Lite System is a complete voice amplification system designed for instructional spaces where voice reinforcement is needed. It uses secure wireless technology in a dedicated spectrum, delivering clear voice reinforcement with reliable performance and reduced interference. Each system includes all the components necessary to distribute the instructor’s voice evenly throughout the classroom, including a wireless microphone system, MPA 152 Plus amplifier, a pair of SM 3 speakers, VoiceLift Pro Port Adapter, mounting hardware, and cable. The system makes it easy to deliver consistent speech intelligibility that helps students hear and engage more effectively throughout the entire space.

Advanced Wireless Technology

VoiceLift Lite uses advanced radio frequency technology operating in a spectrum reserved exclusively for voice communications, providing reliable classroom audio without the limitations of infrared systems. Unlike infrared technology, it is not affected by environmental conditions such as sunlight, windows, or fluorescent lighting.

Pairing technology creates a dedicated connection between each microphone and receiver, preventing interference from microphones in adjacent classrooms. VoiceLift Lite operates independently of Wi-Fi, Bluetooth®, interactive whiteboards, and projector wireless technologies, ensuring dependable performance without disrupting other systems.

With distances operating up to twice that of infrared systems, VoiceLift Lite provides greater flexibility for instructors. Because the technology does not require line of sight, microphones can be worn comfortably in a variety of ways while maintaining consistent audio performance throughout the room.

Plug-and-Play Integration

The VoiceLift Lite Receiver integrates quickly and easily with the MPA 152 Plus stereo amplifier using the VLPA 1 VoiceLift Pro Adapter. The compact receiver, adapter, and amplifier mount conveniently with included ZipClip® mounting hardware, while SM 3 surface mount speakers include SpeedMount® hardware for fast installation. All required cables are included, simplifying deployment and reducing installation time.

Flexible Microphone Support

VoiceLift Lite supports up to two microphones, making it ideal for team teaching, guest instructors, or student participation. Both microphone models feature rechargeable batteries that provide more than eight hours of operation and charge conveniently in a dual-microphone charging base.

Designed for everyday classroom use, the lightweight pendant microphone includes an adjustable lanyard and can be worn around the neck or clipped to clothing. For enhanced classroom support, the pendant microphone also offers an Instant Alert features that allows an instructor to discreetly request assistance with the push of a button when used with an optional MediaLink Plus controller or IPCP Pro xi control processor.

The handheld microphone features an integrated anti-roll collar that helps prevent it from rolling off desks and other flat surfaces.

Complete System

VoiceLift Lite helps ensure every student can hear instruction clearly, from the front row to the back of the room. By delivering consistent voice reinforcement throughout the learning space, the system supports student engagement while reducing vocal strain on instructors. The complete system includes the following components:

VLM 3001 VoiceLift Pro Single Pendant Microphone Kit or VLM 3002H VoiceLift Pro Pendant and Handheld Microphone Kit
MPA 152 Plus Amplifier
SM 3 Surface Mount Speakers (pair) with mounting plates
ZipClip Mounting Kit and ZipClip Caddy
VLPA 1 VoiceLift Pro Port Adapter
100’ SPK 18 Speaker Cable
