ALACHUA, FLORIDA -- London subway system gets  601  Sabine FBX-SOLO SL-820 Feedback Exterminators®. In the latest drive by London Underground to improve customer service and safety standards, Surrey-based communications systems experts, Fone-Alarm Installations Ltd., will install 601 FBX-SOLO SL-820 Feedback Exterminators® into many of London's subway stations. Part of a sophisticated multi-channel, wireless public address system, underground staff carry flush-mount lapel microphones and transmitters, and have the ability to select the zone in which they broadcast, regardless of where they happen to be located at the time. As with all roving wireless microphone systems, feedback is a huge problem, especially with the multiple speaker placement and acoustical characteristics of a London tube, the combination can be disaster. Fone-Alarm Installations has solved the problem by installing Sabine FBX-SOLO SL-820 Feedback Exterminators® for precise feedback control. With eight FBX filters and a built-in noise gate, the FBX-SOLO automatically detects and eliminates feedback, increases clarity and intelligibility, and delivers up to 9dB more gain. Each FBX-SOLO automatically controls feedback for a specific channel, producing custom filtering for each microphone. "The SOLO's are ideal for a project of this nature," states Fone-Alarm's Gordon Desborough. "They are extremely small and highly efficient, providing the extra gain we needed before feedback within the system and improving the overall clarity of the system no end. They are a high quality, cost-effective solution to the problem." Sabine also manufactures the True Mobility Wireless Systems with Targeted Input Processing (FBX, Compressor/Limiter, De-Esser); GRAPHI-Q (all-digital 31-band equalizer, FBX Feedback Exterminator(r), parametric EQ, compressor/limiter and delay) POWER-Q(tm) (nine Pro Audio products in one 2U unit); REAL-Q2 Real-Time Adaptive Equalizer; and the SDA-102 and DQX-206 Digital Delays. Sabine's FBX products are used by such diverse venues as the United Nations (NY), The American Stock Exchange, The Late Show with David Letterman, The Vatican, NASA and Walt Disney Company. In addition, Sabine products have been selected for use at the Sydney Olympics 2000.
