Shure 527B

The 527B is wired for balanced-line operation and is recommended for use where long cable lengths are required, or areas where strong noise fields may exist. The 527B microphone can be fed directly into a standard low-impedance amplifier, or a Shure A95 Series Line Matching Transformer can be used for coupling the 527B to the input of a high-impedance amplifier. A two-conductor shielded cable can be used for extending only the microphone circuit. If both the microphone circuit and the remote circuit are to be extended, a four-conductor cable, having two shielded conductors for the microphone, should be used.
