Dual Receiving

Dual Receiving

Here’s a feature that’s uncommon to other wireless microphone systems; the WR20 receiver can process signals from two microphones simultaneously. You can pair either two WT10 handheld professional microphones, or two WT20 Lapel/Lavaliere mini microphone transmitters, or one each of WT10 and WT20 microphones with the WR20B receiver. That flexibility gives the wireless system the edge over other wireless mics.

Unlimited Mobility

The refined design of the WR20 makes this microphone receiver lightweight and suited for movement. Whether you find yourself lecturing in front of scholars, instructing a Pilates class, or performing at a concert hall, the W200 System will neither constrain nor hinder your performance.

Battery Life That Keeps On Giving

Whether you’re delivering back-to-back presentations in cities across the country, or numerous performances on different stages in one day, the rechargeable Li-polymer battery, included in the Wr20B receiver, give you enough juice to keep going for up to ten hours.

The WR20B is built-in a detachable MMCX antenna jack. By using standard antenna, the receiving range extends from 50 feet (15M) to 70 feet (20M). However, for those who find themselves in larger venues, an additional extension antenna will boost the receiving range up to 150 feet (50M) about equivalent to the half-size of a football

As an additional aspect of our multifaceted microphone, our engineers included a continuous volume control potentiometer in the design. This control, combined with top ranking sensitivity and dynamic range, makes our microphone as versatile as the performers who hold them.

So no matter your mission, perhaps a TED conference or a political rally, the W200’s ground breaking engineering and compact design give you the freedom of movement and the confidence of dependable performance to let you shine in any arena.

Cut Loose on a License-Free Band

All brio W200 systems function on a license-free 2.4GHz band. Our proprietary algorithms and exclusive signal modulation technology carries up to 5Mbps of data. This is vastly superior to any other wireless transmitter on the market, producing the highest highs and sonorous lows for deeply textured, distortion-free notes.
