Modern wireless microphone systems are truly a wonder with more setup features and simpler operation—two trends that frequently work in opposite directions. These wireless systems have all come to the market during a period when manufacturers and users were set reeling from the seismic political and technical challenges coming into force with the digital television transition and there’s more of that in store in the upcoming incentive auctions. Analog, hybrid, and all-digital systems are currently sharing the marketplace and new strides have been made in networked control and digital encryption. As more microphones, musical instruments, in-ear monitors, and intercom systems cram the available RF bands, the world of wireless is becoming an ever more exciting place.

AKG WMS 420

AKG WMS 420

The AKG WMS 420 is designed for small- to medium-size venues where up to eight wireless systems may be needed to operate simultaneously in one frequency band. The group consists of the SR 420 receiver, the PT 420 pocket transmitter, and the HT 420 handheld transmitter with a D5 dynamic microphone head. The pocket and handheld transmitters feature charging contacts for use with rechargeable batteries. The pocket transmitter can be used with the head-worn C555L condenser mic, the C417L lapel mic for presenters, or the guitar set using an instrument cable. The system is compatible with all AKG MicroMics, and it features a low-battery warning indicator.
