Audio-Technica Wireless Accessories

Audio-Technica has introduced several new accessories for its wireless microphone systems, including two new antennas and three antenna accessories: the ATW-DA49 UHF active unity-gain antenna distribution system, the ATW-49CB active antenna combiner kit, ATW-49SP active antenna splitter kit and the ATW-A54P and ATW-A64P UHF-powered dipole antennas. In addition, two new mute switches—the ATW-RMS1 remote mute switch and ATW-RCS1 remote momentary-mute switch—have also been added.

The ATW-DA49 ($499) UHF active unity-gain diversity antenna distribution system enables one pair of antennas to feed multiple wireless systems. Designed to complement Audio-Technica’s 2000 and 3000 Series wireless systems, it is also suitable for A-T’s Artist Elite 4000 and 5000 Series wireless systems, as well as many other wireless systems operating within the 440 to 900MHz range. One ATW-DA49 unit can support up to four wireless receivers directly; each receiver output may also be used to supply signal to an additional ATW-DA49 unit, supporting a total maximum of up to 16 wireless systems in a tiered configuration. All RF connectors are BNC-type; 10 BNC-to-BNC RF interconnect cables and ATW-RM1 rackmount hardware kit are included.

The ATW-49CB ($298) active antenna combiner kit includes two active antenna combiners designed for use with Audio-Technica Artist Elite 5000 and 4000 Series UHF wireless receivers and ATW-A49 LPDA antennas. The active antenna combiner provides unity gain to compensate for RF signal loss when combining signals. Each active antenna combiner is a broadband device (frequency range from 440 to 900 MHz) that joins two incoming RF signals into one outgoing RF signal. One set of Active Antenna Combiners enables two sets of antennas to feed one wireless receiver or distribution system. Each kit includes two dual-input, 1-output active antenna combiners and two 18-inch BNC-to-BNC RG 58 coaxial antenna cables. In addition, the ATW-49CB is suitable for use with a variety of other receivers and antennas.

The ATW-49SP ($298) active antenna splitter kit includes two active antenna splitters for use with Audio-Technica 4000 and 5000 Series UHF wireless receivers and ATW-A49 LPDA antennas. The active antenna splitter provides unity gain so there is no RF signal loss from the original antenna signal. Each active antenna splitter is a broadband device (frequency range from 440 to 900 MHz) that splits an incoming RF signal into two identical outgoing RF signals. One set of active antenna splitters enables one set of antennas to feed wireless receivers of different frequency bands. Each kit includes two 1-input, 2-output active antenna splitters, four 18-inch BNC-to-BNC RG 58 coaxial antenna cables and two BNC-to-BNC barrel adapters.

The ATW-A54P ($898) and ATW-A64P ($898) UHF powered dipole antennas (operating in the 541 to 567MHz and 655 to 681MHz ranges, respectively), when used in a pair configuration, provide effective signal pickup for diversity UHF wireless systems when longer antenna cable runs are required. Designed for temporary or permanent installation, these antennas are powered by 12V DC provided on the antenna cable by the associated receiver or antenna distribution system. An internal gain-setting switch permits selection of +10 or +4dB operation. Screw-terminal connections in the ATW-A54P and ATW-A64P antennas are compatible with RG58-type or RG8-type RF transmission cables.

The ATW-RMS1 ($149)remote mute switch allows users to mute their Audio-Technica wireless microphone quickly and easily. The ATW-RMS1 is installed between the wireless microphone and its associated UniPak™ wireless bodypack transmitter using an HRS-type connector. Featuring a robust toggle switch with positive on/off function, the all-metal ATW-RMS1 is ruggedly constructed to withstand years of use.

The ATW-RCS1 ($149) remote momentary-mute/cough switch features a large, heavy-duty pushbutton switch and all-metal construction, and is easily accessible even under clothing.

The Audio-Technica Wireless accessories are currently available (except ATW-DA49 available in August 2006). For more information, visit For more new sound reinforcement products, visit
