The Schoeps RS 420 L5 Ug is a gooseneck with a miniature LEMO plug for CCM L compact microphones at the upper end and a short, rigid tube at the bottom. Above this tube the lower part is flexible. The SRS version has a second flexible part near the upper end of the tube, allowing the microphone's angle to be set.
To isolate the microphone from solid-born sound, due to the length of the gooseneck two AF 1 flanged mounting adapters with internal shock mount should be used, one above the other. These are held together by an ST 20-3/8 mounting cylinder of at least 61 mm length, with other lengths available on request.
