Audio System Integration & Interface Compatibility
The Ahuja AWM-520VH wireless microphone system is engineered for seamless integration across commercial and industrial public address (PA) frameworks. The table-top receiver is equipped with a dedicated rear-panel 6.3 mm (1/4") phone jack that provides an adjustable audio output range of 0 to 50 mV. This output specification ensures direct interfacing with standard unbalanced 6.35 mm microphone inputs as well as auxiliary/line-level preamplifier inputs on PA mixing consoles, booster amplifiers, integrated mixer-amplifiers, active/powered speakers, and dedicated lectern or podium sound installations.
Because the receiver delivers clean audio with a total harmonic distortion under 0.5% and a signal-to-noise ratio greater than 80 dB, it matches impedance and signal level requirements across commercial audio equipment without introducing input stage clipping or signal degradation. A compatible 6.3 mm patch cable is supplied with the system to facilitate direct connection between the receiver output and destination audio hardware.
Multi-Channel VHF Frequency Deployment
For facilities requiring multi-microphone setups—such as multi-room educational institutions, corporate training complexes, and adjacent auditorium zones—the Ahuja AWM-520VH is manufactured across six distinct factory-preset VHF carrier frequencies. This multi-frequency design allows system planners to select unique operating frequencies for distinct physical zones or stages, eliminating RF cross-talk and channel collision. Operating on stable VHF high-band frequencies with a tight frequency stability tolerance of ±0.005%, multiple individual AWM-520VH units can operate within the same facility when paired with their corresponding matched handheld transmitters.
Power Supply & Electrical Compatibility
The system components integrate into standard electrical and battery power environments:
- Receiver Power Requirement: The table-top receiver operates on 9V DC and includes a dedicated external AC adapter designed for standard 220V–240V AC, 50 Hz power networks. This makes it fully compliant with standard regional mains power infrastructure across commercial venues.
- Transmitter Power Requirement: The handheld transmitter requires a 1 × 9V battery (they are not included) to operate. With an energy-efficient current consumption rating of under 30 mA, standard 9V battery (they are not included) cells provide steady, long-lasting performance for continuous speaking presentations.
Acoustic & Application Environment Compatibility
The dynamic cardioid transmitter element is tuned with a 40 Hz to 13,000 Hz frequency response and a maximum deviation of ±25 kHz, delivering high speech intelligibility while minimizing acoustic feedback in high-reflectance spaces. The receiver integrates dedicated noise squelch circuitry and a fully extendable telescopic antenna, ensuring stable VHF link reception up to the full operational boundary of the 10 mW transmitter. This makes the AWM-520VH hardware profile ideally suited for commercial PA installations, seminar halls, places of worship, auditoriums, stadia, and conference venues.
