AKG PT470 Professional Wireless Body-Pack Transmitter - Band 7 - 50 milliWatt

The PT470 is an analog professional wireless body-pack transmitter in a small, rugged housing. A pilot tone transmission prevents unexpected startup 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. An optional RMS4000 external mute switch allows the user to mute the transmitter remotely. Its professional mini XLR audio connector makes the body pack compatible with a broad range of lavalieres and headsets.
