503BG Gooseneck Microphone

Developed for computer voice recognition applications, the 503BG gooseneck microphone offers excellent voice fidelity while reducing background noise. Also use the 503BG microphone in other close-talking applications such as paging and talkback.

This compact gooseneck mic reduces background noise for excellent voice fidelity. Humbucking coil minimizes undesired hum effects. Cardioid, Dynamic.

The 503BG gooseneck microphone features a low-impedance, moving coil type transducer with an integral humbucking 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 (not included), a fixed pipe or a microphone stand using a standard 5/8"-27 thread.

Acoustic Considerations: The 503BG maximizes performance in close-talking applications through its tailored frequency response, directionality and distance discrimination. It optimizes and controls sounds within the 100 to 7000 Hz frequency range and reduces sounds outside that range. The 503BG rejects noise through its inherent directional properties and discriminates against distant sounds in favor of close-range sounds.
