The AMT WS is Applied Microphone Technology’s flagship double microphone system for Clarinet. Designed, manufactured by hand, and distributed by AMT in the USA. The system is intended to clip onto standard Bb Clarinet"s. The WS is the # 1 choice for top professionals that look for the most natural sound reproduction possible from a clip on microphone. All versions of the WS now include updated features including D.C.T. (Disconnect Cable Technology) with the ability to connect the Wi5C creating a belt pack free wireless system. The WS in it"s stock configuration is the perfect choice for the player that requires a hard wired (non wireless) belt pack style setup and intends to perform only on clarinet. The WS comes in four versions. (WS, WS Studio, WSW - Shure, WSW - Sennheiser) All of the microphones are identical and all can also be used wirelessly. The decision between the versions comes when one would choose between wireless, hardwired, and / or require both. The WSI comes complete with the Inline preamp, case, and AMT disconnecting cable technology to allow the microphone to be used wireless with the AMT Wi5C, Shure or Sabine Wireless.
