Public Address Amplifier and Mixer Compatibility
The Ahuja AUD-59XLR unidirectional dynamic microphone is engineered for seamless electrical and acoustic matching with standard commercial, institutional, and industrial public address systems. Featuring a nominal electrical impedance of 600Ω, the microphone provides direct impedance matching with balanced and unbalanced low-to-medium impedance microphone inputs commonly found on Ahuja PA amplifiers, commercial mixer-amplifiers, and sound reinforcement consoles.
With an open-circuit sensitivity rating of 2.5 mV/Pa and a specialized dynamic capsule architecture, the AUD-59XLR generates clean mic-level signals without requiring external active power or phantom power supply circuits. This ensures plug-and-play interoperability across standard preamplifier stages, audio processing equipment, and multi-zone commercial paging systems designed to accept dynamic microphone level inputs.
Connector and Cabling Interfacing
The unit comes supplied with a dedicated 4.5-meter shielded audio cable terminated with an industry-standard 3-pin XLR connector. This configuration ensures immediate compatibility with professional-grade sound equipment, patch bays, floor stage boxes, and wall-mounted input plates equipped with standard 3-pin XLR female interfaces.
The 4.5-meter cable length offers ample physical routing flexibility for podiums, reception desks, security control desks, and announcement stations. The integral shielding on the 4.5 m lead minimizes electromagnetic interference (EMI) and radio-frequency noise pick-up across standard cable runs in electrically active industrial or commercial environments.
Microphone Stand and Mounting Integration
For secure mechanical installation, the Ahuja AUD-59XLR package includes a dedicated quick-detachable microphone holder. This holder allows immediate mounting onto standard public address floor stands, tabletop base stands, podium goosenecks, and desktop mic booms commonly utilized in auditorium, conference, and dispatch setups.
The quick-detachable mechanism permits fast transitions between fixed-stand mounting and hand-held operation during live announcements, presentations, and facility address tasks without requiring tool-assisted removal.
Acoustic and Frequency Profile Suitability
The microphone features an engineered frequency response of 100 Hz to 10,000 Hz, specifically optimized for vocal clarity, intelligible speech reproduction, and general public address requirements. Combined with its unidirectional polar pickup pattern, the AUD-59XLR provides directional voice capture while rejecting off-axis environmental noise and minimizing acoustic feedback when operating in proximity to PA speakers and sound columns.
