Professional multichannel wireless sport set from WMS 470 series that features a pilot tone transmission to prevent unwanted noise and is ideal for conference, medium theatre and houses of worship applications. It works within a bandwidth of 500.1 to 530.5 MHz and includes a SR470 receiver, a PT470 body-pack transmitter, a C544 L head-worn microphone, a rack mount kit, universal power supply, an AA size battery, two antennas and a belt clip. The SR470 analogue space diversity professional wireless receiver comes in a rugged half-rack metal housing. The enhanced Auto Setup with channel preview, Environment Scan and Rehearsal mode allows a very quick and easy system setup. The programmable backlight changes colour to warn the user of critical operating conditions e.g. transmitter low battery information, audio peaks, or low radio signal strength. The PT470 analogue professional wireless body-pack transmitter in a small, rugged housing provides the pilot tone transmission, which prevents unexpected start-up noise, continuously sending transmitter data, including low battery information, to the receiver. An enhanced battery management allows up to 14 hours of operation on a single AA-size battery. With the integrated charging contacts, a standard NiMH rechargeable battery can be charged inside the transmitter. Its professional mini XLR audio connector makes it compatible with a broad range of lavalieres and headsets. The C544 L high-performance head-worn miniature condenser microphone with an easily fitting headband is perfect for gymnastics instruction, active stage movement and other hands-free speech applications. A transducer shock mount reduces body noise to a minimum and the short microphone arm places the microphone in the right position to the mouth to minimize pop and breathing noise. A special moisture shield on the boom prevents the microphone from being clogged by sweat or makeup. The microphone comes with a three-pin mini XLR connector and four drop rings for sweat and water protection and has a cardioid polar pattern for problem-free use with high ambient noise rejection.
