Unwanted audio ambience may be generated if working in 'untreated' acoustic environments when recording and this naturally affects the quality of any signal captured via microphone. Six years ago sE Electronics was the first company to develop a solution to this commonplace problem and launched the highly successful Reflexion Filter. The sE Electronics RF-X is the latest high-performance acoustic filter joining sE's highly-acclaimed line of successful and industry standard Reflexion Filter products. With a new lightweight body and re-designed lightweight clamp assembly, the RF-X is simplicity itself, providing unbeatable performance and ease-of-use. The sleek design of RF-X clamp assembly allows it to be used on almost any microphone stand. It has been simplified to achieve this and allows for vertical mounting only - making it the perfect solution for vocal recording. sE Electronics Item No. RF-X Sam Ash Direct has all of the accessories and tools you need for mobile and desktop production!
