  • Notes
  • Type:Dynamic, Unidirectional (cardioid), Close-Talking, Impedance 170 ohms This microphone is designed especially for use in computer voice recognition applications. It is also suitable for other uses such as paging, talkback, and other communication-type applications where excellent voice fidelity and reduction of background noises are needed. The frequency response is tailored to produce an essentially constant output voltage over the voice spectrum when used close to the sound source. The transducer is a low-impedance, moving coil type with integral humbucking coil. The microphone case is aluminum with a black enameled finish. It has a standard 5/a"-27 thread suitable for mounting on a flexible gooseneck, fixed pipe, or microphone stand. The unit is supplied with an attached two-conductor shielded cable with a built-in strain relief. Currently-available Model 562 is the equivalent type (January 2012)
