The VoiceLift Pro Microphone System represents the next generation of classroom voice amplification technology. It uses wireless technology, employing digital transmission and pairing in a dedicated spectrum to provide dependable performance. Benefits include superior sound quality, reliable and long-range transmission, as well as reduced interference. Each system contains all the components necessary to evenly distribute the teacher's voice throughout the classroom, including wireless microphone, receiver, PVCA 452 Controller Amplifier, speakers, mounting hardware, and cables.
Advanced Wireless Technology
The VoiceLift Pro Microphone is based on an industry standard radio frequency technology operating in a spectrum reserved exclusively for voice communications. This technology is not susceptible to environmental factors, such as windows, sunlight, and fluorescent lighting, that create problems for infrared systems.
Upgradeable to a Complete PlenumVault Direct View AV System
At the heart of each system is the Extron PVCA 452 controller amplifier that allows the system to be upgraded to an easy-to-use AV and control system. Simply add a display, input wallplates, and a user interface to create a completely integrated system that supports video sources, voice amplification, and intuitive control.
Flat Field Speakers
VoiceLift Pro Microphone Systems include Extron FF 120 full-range Flat Field® speakers. Extron’s patented Flat Field Technology reduces beaming of mid and high frequencies, delivering consistent sound levels across the listening area to each student. The speakers also offer an extraordinarily wide dispersion of 170 degrees, allowing each speaker to cover a larger area and reducing the number required in a standard classroom.
Flexible Mounting Options
Flexible mounting options are available to fit any room design. The unique WMK 160 wall mount kit securely mounts and conceals critical components to a wall, protecting them from tampering and theft. The PVM 220 PlenumVault® Mounting Kit mounts system components in the plenum space above a suspended ceiling. Additionally, the ZipClip® 400 mounting option enables installation behind flat panel displays.
Complete System
VoiceLift Pro Microphone Systems are standalone classroom voice amplification solutions. VLS systems include the following core components. The VLS 3002, VLS 3002W, and VLS 3002P add a second pendant microphone while the VLS 3002H, VLS 3002HW, and VLS 3002HP add a VLH 302 handheld microphone.
VoiceLift Pro Microphone System Core Components
- VLP 302 VoiceLift Pro Pendant Microphone
- VLR 302 VoiceLift Pro Receiver
- VLC 302 VoiceLift Pro Charging Station
- PVCA 452 Controller Amplifier
- FF 120 plenum rated Flat Field® Speakers, pair
- WMK 160 Wall Mount Kit, PVM 220 PlenumVault Mounting Kit, or ZipClip 400
- 3' CATx shielded twisted pair cable for connecting the PVCA 452 and receiver
- 100' SPK 18 Precut Speaker Cable - Plenum
Features
- Complete high performance voice amplification system for instructional spaces
- Advanced RF wireless technology provides superior sound quality, increased reliability, long-range transmission, and reduced interference
- Supports up to two microphones per classroom for team teaching or student participation
- Powerful, integrated 50 watt, two-channel amplifier — Outputs 50 watts, 25 watts rms per channel, at either 4 or 8 ohm speaker connections. This allows for a streamlined installation and plenty of power to drive speakers to fill typical-size classrooms with full, rich sound.
- Audio input mixing — The PVCA 452 can mix multiple audio sources. This includes voice reinforcement audio from the VLR 302 VoiceLift Pro microphone system and program audio from analog and digital sources. Program audio can be connected via TOSLINK optical fiber, HDMI ARC, and auxiliary line audio. Instructors can narrate over AV lesson presentations, add music, and perform other sophisticated audio management to make AV lessons more engaging and relevant.
- Includes one pair of Extron patented Flat Field® speakers for consistent sound levels across the listening area
- Instant Alert feature on the pendant enables the teacher to request assistance with the push of a button
- Page sensor port — Allows connection of a priority page sensor that detects announcements coming over public address speakers and mutes the PVCA 452 audio output to ensure the classroom AV does not compete with important PA messages.
- Lightweight pendant and optional handheld microphone ensure continuous usage throughout the school day on a single, rechargeable AA battery
- Audio DSP suppresses feedback while maximizing sound quality and intelligibility
- Durable and reliable design to withstand the rigors of daily classroom use
- Fixed and variable line level outputs — The fixed output is ideal for recording devices, remote learning applications, or other equipment such as ALS - assistive listening systems. The variable output is designed to drive a power amplifier.
- Receive program audio from the display over HDMI cable using ARC - Audio Return Channel — ARC allows transfer of audio from the flat panel display back to the PVCA 452 using the HDMI connection. This enables users to play audio through the Extron-exclusive patented Flat Field® speakers in the system rather than the flat panel display's speakers, provides additional flexibility in audio support, and facilitates the system's adaptability to evolving needs.
- Upgrades easily and affordably to a complete PlenumVault Direct View classroom AV system
- Integrates with GlobalViewer Campus Communication Suite — GlobalViewer Campus Communication Suite is the modern, simple way to implement bells, public address announcements, and intercom communications throughout campus over the network from an intuitive web browser interface.
- Supports LinkLicense® — Extron LinkLicense unlocks features that add convenience, expand system functionality, and enhance the capabilities of Extron products.
- LinkLicense for Audio Streaming enables the PVCA 452 to directly decode and play GlobalViewer Campus Communication Suite PA announcements and bell audio through classroom speakers.
- LinkLicense for User Interfaces allows a mobile device or computer to function as the system’s primary control interface.
- Supports Ethernet-controllable devices — Allows control of multiple Ethernet-enabled AV devices such as displays, switchers, and sources.
- Vast library of Pro Series Ethernet device drivers for use with Extron Global Configurator® software — Start and execute projects quickly using Extron Global Configurator device drivers to control various Ethernet-enabled display and source devices.
- Easy setup and configuration using Extron software — Conveniently configure the system using Global Configurator Plus and Professional, Toolbelt, and PCS Product Configuration Software.
- WMK 160 wall mounting, PVM 220 PlenumVault® mounting, and ZipClip® 400 mounting options — Securely mount and conceal system components to a wall, in the plenum space above a suspended ceiling, or behind a flat panel display.
