The Lectrosonics IFB system virtually guarantees an interference-free means of directing on-camera talent. The transmitter can transmit in 256 different UHF frequencies separated by 100kHz steps ensuring there is no interference with other wireless devices – a common problem with other devices, especially in studio or live event situations. Fed by either a signal from an intercom system or by a direct mic, the transmitter has a range of over 1/4 mile and its noise reduction features plus high-end processing provides a very high quality audio feed to the talent.
Other features include automatic squelching of jarring audio tones; rugged, compact construction; wireless earbud, and long life battery consumption.
The price includes one talent receiver. Additional receivers are available at $25/day each.
