Designed for use on professional tours, in stadiums, concert halls, houses of worship and other demanding audio environments, Audio-Technica's dual-receiver Artist Elite 5000 Series provides incredible audio quality and proven, critically acclaimed performance for artists, broadcasters and presenters worldwide. The newly upgraded 5000 Series sets standards for wireless live sound, with its dual-compander circuitry that processes high and low frequencies separately. It also features A-T's proprietary IntelliScan capability, 996-channel frequency agility, True Diversity operation, soft-touch controls, digital Tone Lock squelch, backlit LCD displays on all transmitters, and locking battery doors on the UniPak body-pack transmitters. With two independent True Diversity receivers in a single full-rack housing, the 5000 Series conserves rack space while providing outstandingly reliable and flexible performance. Receivers may be linked to form a complete system in which the built-in IntelliScan capability automatically determines and sets the best available frequencies on all linked receivers. Equipped with Ethernet ports, the 5000 Series receiver allows computer management and control from anywhere via new wireless control software; access computer control from a front-of-the-house rack in the same room, or clear across the country, making it truly a 21st century product. Multiple system configurations are available, with handheld vocal microphone/transmitters and UniPak body-pack transmitters designed for use with lavalier, headworn and instrument microphones as well as electric guitars.
