The System 10 PRO Rack-Mount Digital Wireless System from Audio-Technica includes an ATW-RC13 receiver chassis with rack-mount adapters, two ATW-RU13 receiver units with corresponding AT8690 receiver unit mounting brackets, a joining plate, one RJ12 cable, one AC adapter, and two ATW-T1007 microphone desk stand transmitters. The receiver and transmitter feature an easy-to-read display. The system provides interference-free operation in the 2.4 GHz range (outside TV bands). The half-rack chassis is equipped to house two receiver units that can be operated locally or released from the chassis and mounted remotely (up to 328' away) via Ethernet cable. Up to five chassis (10 receiver units) can be linked using the RJ12 cable included with the system, creating a stable, multichannel system with the simultaneous use of up to 10 channels. The PRO Rack-Mount features 24-bit operation, easy setup, clear, natural sound quality, and three levels of diversity assurance (frequency, time, and space). Frequency Diversity sends the signal on two dynamically allocated frequencies for interference-free communication. Time Diversity sends the signal in multiple time slots to maximize immunity to multipath interference. Space Diversity uses two antennas on each transmitter and receiver unit to maximize signal integrity.
