- Cardioid Polar Pattern
- Picks up the most sound in front of the microphone and some from the sides. Less susceptible to feedback in high volume environments.
- Tailored Frequency Response
- Smooth, extended response. Tuned to accentuate specific types of instruments, or voices.
503BG“Close-Talk” Microphone
- Dynamic
- Simple, rugged diaphragm/coil. handles extreme volume levels without distortion.
- Recommended Uses
- Paging
Additional Recommended Uses:
- Intercom
- Voice Recognition
Designed for indoor communication systems, including transportation, restaurant, and industrial applications. Suitable for environments with high levels of background noise.
Note: For proper operation, mouth-to-microphone distance should be 2 inches (5 cm) or less.

- 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.
