RCAS™ Remote Control

RCAS™ Remote Control


RCAS™ (Remote Control Audio System™) enables audio technicians to make on-the-fly adjustments to the transmitter functions.  Because RCAS™ is an RF based system it will operate through clothing, uniforms, walls and over long distances.

From the NBA to the Rockettes

RCAS™ technology is indispensable in situations where it’s not practical for an audio tech to be in contact with the transmitters.  When used to manage dozens of transmitters at once, it’s awe-inspiring.  The innovative RCAS™ technology, developed in 2006 specifically for the NBA, has since become popular in sports arenas and world leading theatrical venues like Radio City Music Hall where it has worked flawlessly for hundreds of live performances since 2009.

Share the Spectrum

By turning on and off groups of transmitters, and changing their frequencies, it is possible to reuse one receiver (and one frequency) with multiple transmitters used at different times in a performance. In the case of Radio City Music Hall, in RF congested New York City, only 80 usable frequencies were available. There, 80, two channel receivers are shared by 300 transmitters.

RCAS™ consists of Transmitters, MicControl Software, QG-N3 networked gateways, and QG-H1 remote hand controls.


RCAS™ enabled QT-5100 transmitters maintain the same rugged, miniaturized packaging that makes Q5X the standard for demanding wireless microphone applications. The QT-5100 family of transmitters come in a variety of unique form factors; PlayerMic®, Incognito®, BeltMic® , AquaMic® RefMic® .

MicControl Software

The RCAS™ MicControl software runs on any Windows computer connected to a QG-N3 network gateway by ethernet or USB.  This control system can; turn transmitters on and off, change frequencies, RF power levels and mic gain, organize transmitters into groups and monitor their status and battery level as well as change companding modes. The system can be arranged to support hundreds of transmitters controlled over an entire venue. Up to 16 QG-N3 network gateways can be connected via ethernet to provide wide area control.  When the transmitters are not in control channel range, they maintain their settings, making the system failsafe. The transmitters are controlled through the QG-H1 RCAS™ enabled hand held remote control and/or QG-N3 networked RCAS™ gateway connected to the computer (can also be USB connected)


Two types of gateway are available: The QG-H1 MicCommander, hand held remote control with a range of 40 meters and the QG-N3 MicCommander network gateway.

The RCAS™ MicCommanders communicate with the transmitters via a 2.4GHz control channel.  When using multiple QG-N3 network gateways there is the added benefit of easily identifying the approximate location of the transmitters based on which gateway they are closest to and communicating with.


Since the transmitter settings are controlled directly from a computer or hand held remote, RCAS™ specific receivers are not necessary. The rack mount QR-2100 or QR-M2 mobile receivers are recommended. The QT-5100 transmitters, with their selectable companding modes, will also work with some other brands of wireless receivers.
