As the latest wireless microphone products introduced at the NAB convention show, the application of this kind technology is taking many twists and turns.
Often thought of as just mics that send a signal to an off-stage or off-set receiver so on-air talent doesn't need to tug on a connecting cord, these products show that wireless may be complicated by spectrum allocations and site congestion, but their use is hardly diminishing.
LCDs added to these systems have allowed for some interesting new features, not the least of which is being able to check out the spectrum on-site to see which frequencies are in use and which are free at the time.
This article also includes a contact list, so you can follow-up on more information on all those covered and those who didn't show products at NAB this year.
AUDIO-TECHNICA: The company chose NAB to introduce a new wireless range of RF cables, UHF antennas, and UHF distribution systems, but their U100 high flying system and their 7000 Series InvisibleLink caught the attention of attendees. The U100 has 100 PLL-synthesized switchable channels, uses a helical filter receiver design, balanced audio output with level control, and has receiver antennas that are removable.
The 7000 Series multichannel UHF true diversity wireless systems also feature 100 PPL-synthesized frequencies selectable via switches on both the transmitters and receivers.
The ATW-T73 handheld mic/transmitter features the same condenser element used in the legendary AT4033 studio mic, while the ATW-T76 handheld mic/transmitter features a Hi-Energy dynamic element.
Other transmitter/receiver packages include the ATW7373 condenser mic; the ATW-7375 UniPak using a ATW-R73 receiver and a ATW-T75 transmitter; the ATW-7376, ATWR73, and ATW-T76.
AZDEN: The company's all-new, low-cost 1000 Series UHF system has 121 digitally selectable UHF frequencies (723 to 735 MHz). It has performance levels previously only available on systems costing $2,500 and up. The 100OURX receiver uses Azden's proprietary Diversity Logic Control for noise-free reception. The 100OBT Bodypack matching transmitter uses an LCD readout system, has digital frequency selection, and various mic options. It'll work with dynamic and phantom-powered mics. Both the 100OBT and the 100OXT use less than 60 mA from a single 9 Volt alkaline battery.
