U100 Series Camera-mount UHF Body-pack and Plug-on Wireless Systems (DISCONTINUED)

A-T’s compact U100 systems are designed to provide broadcasters and videographers with outstanding sonic quality and trouble-free, dependable performance. Engineered for use in audio-for-video applications, with the receiver mounted on a camera and connected to the camera’s audio input, U100 systems provide a choice of 100 PLL-synthesized UHF frequencies in one of two UHF frequency ranges. Each system includes a receiver and either a body-pack or plug-on transmitter.

Available in two frequency ranges:
656 - 668 MHz (TV channels 45 - 47) and 728 - 740 MHz (TV channels 57 - 59)

100 PLL-synthesized channels selectable via switches on receiver and transmitter

True Diversity operation selects the better signal from two independent receiver sections, reducing dropouts

Robust, rock-solid RF design proven in demanding commercial applications

Interference-resistant UHF band operation

Receiver and transmitters feature rugged metal construction

Helical filter receiver design improves rejection of unwanted signals

LEDs on receiver indicate A or B antenna status, AF peak, and power status

Balanced audio output with level control

Removable receiver antennas with BNC connectors

Receiver operates on two internal 9-volt batteries or external 12V DC

Headphone jack with volume control

Hinged battery doors on receiver and transmitters

ATW-U101 body-pack transmitter features industry-standard Switchcraft 5-pin mic input connector for use with the following optional accessory microphones: AT831cT5, AT892cT5, AT892cT5-TH, AT898cT5, AT899cT5, AT899cT5-TH, MT830cT5, MT830cT5-TH

Optional cables:
AT8340 - Input cable connects mics with 3-pin XLRM-type output to ATW-T101(x) body-pack transmitter. 4.3' (1.3 m), XLRF to TA5F connectors.
AT8341 - Output cable connects ATW-R100(x) receiver to camera or other device. 19" (0.5 m), XLRF to right-angle 3.5 mm stereo mini-plug.
