Brand Name: Electro-Voice

Model Number: RE97Tx


The Electro-Voice® RE97Tx is an Ultra-low profile, omnidirectional, back-electret condensor headworn microphone designed for use with standard EV and Telex belt packs. The RE97Tx is intended for spoken word use such as Houses of Worship, Corporate AV, Theatre, Fixed Install, and other venues where a fullrange, natural, well-balanced sound is required. The omnidirectional polar pattern of the RE97Tx provides a clean and accurate sonic quality and uniform output regardless of the microphone’s position relative to the sound source. The RE97Tx is designed to be extremely flexible and easily formed to fit over the ear of any user. The malleable boom and earhook can be shaped to match virtually any contour. The TA4F terminated cable is discretely routed behind the user and attaches to the shirt collar with the elegant clothing clip included, keeping the cable out of the way and preventing the microphone from being pulled off the user’s ear. The supplied windscreen can be used in windy environments and to reduce breath noise. The RE97Tx comes with a shielded 4ft cable terminated in a high quality TA4F connector. It is wired for use with standard EV and Telex belt packs including the EV (BPU-2/CSB-1000) and Telex (WT-500/WT-1000) bodypack transmitters and operates from a 5VDC supply.
