Audio Technica ATW-1102 Wireless Handheld System


The Audio Technica ATW1102 is a high-fidelity Wireless Handheld System, designed to provide performing musicians and presenters with advanced 24-bit operation, easy setup and clear, natural sound quality. Operating in the 2.4 GHz range, far from TV and DTV interference, System 10 offers extremely easy operation and instantaneous channel selection.

Up to eight channels may be used together without any frequency coordination problems or group selection issues. System 10 receivers and transmitters offer an easy-to-read digital ID display. System 10 wireless ensures clear communications by providing 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. Finally, Space Diversity uses two antennas on each transmitter and receiver to maximise signal integrity. Featuring stackable, contemporary styling, System 10 is available in multiple system configurations, with handheld vocal microphone/transmitters and UniPak® body-pack transmitters designed for use with lavalier, headworn and instrument microphones as well as electric guitars.

Each configuration includes the ATW-R1100 receiver and either a body-pack transmitter or handheld microphone/ transmitter. The ATW-R1100 is a digital receiver offering volume control along with AF Peak and Pair indicator lights.
