Product Overview

The 503BG is an unidirectional dynamic Close-talk Microphone designed for computer voice recognition, indoor communication systems, including transportation and restaurant applications. The microphone offers excellent voice fidelity while reducing background noise. Also use the 503BG in other close-talking applications such as paging and talkback. The microphone features a low-impedance, moving coil type transducer with an integral hum bucking coil and an attached two-conductor shielded cable with a built-in strain relief. It produces a frequency response with an essentially constant output voltage over the voice spectrum when used close to the sound source. The 503BG’s case is aluminum with a black enamel finish. It mounts to a gooseneck, a fixed pipe or a microphone stand using a standard 5/8 inch-27 thread.
  • Minimal pick-up of background noise due to close-talk design
  • Hum-bucking coil reduces induced noise from computer displays
  • Attaches to flexible gooseneck arm (not included)
  • Two conductor, shielded, bare-ended (no connector) and straight cable
  • Does not require DC power for operation
  • Constant output over voice spectrum when close talked
  • Low-impedance design permits long cable runs in extreme hum fields
  • Small unobtrusive design does not interfere with CRT visibility
  • Rugged and reliable for years of consistent operation
