Designed for indoor communication systems, including transportation, restaurant, and industrial applications. Suitable for environments with high levels of background noise.
Developed for computer voice recognition applications, the 503BG microphone offers excellent voice fidelity while reducing background noise. Also, use the 503BG in other close-talking applications such as paging and talkback.
The 503BG 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, a fixed pipe or a microphone stand using a standard 5/8"-27 thread. To secure the mounted 503BG, tighten the 4-40 screw with the supplied #4 Allen (hex-head) wrench.
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.
Operation
For best performance, speak as close to the 503BG as comfort permits. A distance of 1 to 5 cm (0.4 to 2 inches) provides the greatest discriminations between voice and background noise.
