Wireless Audio Solutions for Live Theatre

We understand the problems of wireless audio in theatrical production, and offer an unrivalled theatre specific solution.

Central Control

RCAS (Remote Control Audio System) can vastly simplify management of multiple radio mics. It allows you to control all the transmitters, individually or in groups, from a central computer via a 2.4GHz control channel.

This system has several huge advantages for theatre:

  • All the battery levels can be seen at a glance
  • Mics that are not in use can be remotely put in standby in order to save battery power, you can do a full sound check and then power down the whole group of transmitters until showtime
  • A large pool of radio mics can share fewer receivers by turning on and switching the frequencies of only the mics on stage at any one time
  • In case of radio interference, frequencies can be changed on the fly
  • The location of all the actors can be identified based on their closest control gateway
  • No more disturbing talent to get at body packs buried in a costume


Size and Comfort

The QT transmitters lead the industry in comfort and concealability, they are all sweat and splash-proof and run much cooler than other wireless mics. The QT-5100 PlayerMic is a flat, flexible, rubber body packs that was originally developed to be worn comfortably by NBA players. It can be tucked into a waistband or taped to the body. The QT-5100 Incognito is a two part wireless mic that can be concealed in a wig or bra.

8 to 12 Hours on a Charge

The internal lithium batteries are designed for extreme long life, 8 to 12 hours on a single charge. Rechargeable batteries are not only better for the environment, they offer a significant cost savings over disposables.


We originally developed the QT line of radio mics for pro sports; they’re built to take abuse, season after season.

High Quality Sound

All Q5X transmitters have dual companding, are frequency agile in the 525-600MHz UHF band and provide high quality broadcast audio.

Mature Technology

No other wireless system can offer the same benefits and flexibility as RCAS. It is a stable mature technology that has been in use for several years and hundreds of performances in major theatrical venues.
