NMK Electronics has supplied an Axient wireless microphone system to Sharjah TV, a key broadcaster in the UAE.
The system comprises six channels of AXT400 receiver, six AXT100 Axient Bodypack Transmitters and four AXT200 Axient Handheld Frequency Diversity Transmitters with KSM9 mic capsules. Axient is a ‘mission-critical’ system that continuously scans for problems, maintaining back-up frequencies in readiness to replace any that are compromised. Using a data backchannel, Axient uses frequency diversity to switch channels before interference becomes audible, either automatically or in response to a manual alert. The system also tracks battery life to within 15 minutes’ accuracy.
The accompnying Wireless Workbench 6 software performs live RF scans and analysis, with graphic indications and device markers presented on a high-resolution frequency plot. During a TV broadcast, Wireless Workbench 6 enables live remote adjustments to be made to networked hardware, for instant changes to frequency, gain and RF output power, as well as indicating battery life, RF signal strength conditions.
Promoting use of the Arabic language and national identity,’ Sharjah TV t highlights both environment and community issues, and follows the country’s activities, giving special attention to family, children and the non-Arab community in the UAE. It broadcasts programmes that address social problems and traditional restrictions.
‘Axient addresses the issues involved in high-density RF environments,’ says Shure Product Manager, Shajahan KK, at NMK. ‘The system manages transmitters, receivers, antenna systems, the RF spectrum itself, even the batteries you’ll use. The capability to fix the problems, before the user even knows there’s a problem, is incomparable.’
‘Our engineers are very satisfied with the great sound quality of the system,’ says, Sharjah TV’s Khaled Al Shehi. ‘The Axient features, such as interference detection and avoidance, transmitter remote control and frequency diversity, make our job easier in difficult RF conditions.’
