The Ahuja AUD-70XLR is one of the most popular and reliable wired, dynamic microphones in the general Public Address category. It is a workhorse known for its durability and clear speech reproduction. Here are the specifications and details on how it fits into your proposed setup. Ahuja AUD-70XLR Technical Specifications Feature Details Type Dynamic Polar Pattern Unidirectional (Cardioid) Frequency Response 50Hz – 15,000Hz Impedance 600Ω Sensitivity 2.5mV/Pa Body Material Zinc Die-cast (typically black finish) Connector 3-pin XLR (male on mic) Supplied Cable Usually, a 6-meter, twin-core shielded cable with an XLR (female) on one end and a 1/4” (6.3mm) phone plug on the amplifier end. Key Features Unidirectional Pattern: It is designed to pick up sound from the front and reject sound from the back and sides. This is crucial for PA systems as it minimizes feedback (screeching) when the microphone is used near speakers like the SCM-15XT. Speech Clarity: The 50–15kHz frequency range is optimized for human vocals. It handles the “popping” sound of ‘P’s and ‘B’s well due to its internal foam windscreen. Rugged Construction: It has a heavy-duty, die-cast zinc body that can withstand being dropped and heavy daily use in places like schools or houses of worship. Noiseless Switch: It features a sliding on/off switch that doesn’t “pop” or crackle when operated. How it Works with your Column Speakers The AUD-70XLR microphone and the SCM-15XT speakers are a classic combination for public address systems. They are both optimized for speech intelligibility rather than studio-quality music. Connection: You plug the microphone cable into the MIC 1 or MIC 2 input of your 100V PA amplifier. Feedback Management: Since the microphone rejects sound from behind, you should place the SCM-15XT speakers in front of the person speaking. If the person must stand near the speakers, tilt the speakers down toward the audience and away from the microphone’s position.
