The AP42 Performance Series Dual-Channel Bodypack Wireless System from Audix includes the R42 2-channel diversity receiver and two B60 bodypack transmitters. The R42 diversity receiver operates on a wide-spectrum frequency range of 522 to 554 MHz and offers one-touch auto scan searches for clear channel. It comes in a 19" rackmount chassis and includes BNC cables for front mounting antennas. It also features an internal antenna combiner for dual antenna operation. Thanks to the one-touch sync function, this receiver easily links to the B60 bodypack transmitters placed within 300'. These bodypack transmitters can be used with any lavalier, headworn, or instrument microphone in the Audix line, as well as electric guitar and bass. Enclosed in a metal housing with modular antenna design, each transmitter comes with AF and RF gain controls and a soft mute switch which also serves as an on/off switch when needed. They also feature a high-contrast LCD display with group, channel, and battery indicator.
