The Ahuja AWM-495V2 dual-channel VHF wireless microphone system is engineered for seamless interfacing with commercial public address (PA) systems, audio mixers, active loudspeaker units, and signal processors. Equipped with quartz crystal-locked VHF high-band transmission and standard 6.35 mm (1/4") output jacks, the system integrates smoothly into existing AV architectures in auditoriums, conference rooms, houses of worship, and educational facilities.
Audio Output & Mixer Input Interfacing
The AWM-495V2 receiver features flexible audio output routing via three dedicated 6.35 mm phone jacks located on the rear chassis. It provides individual line outputs for Channel 1 and Channel 2, as well as a combined mixed output (Channel 1+2). Each output delivers a nominal audio signal level of 0–55 mV at an output impedance of 1 kΩ, perfectly matched for unbalanced microphone-level inputs on audio equipment.
- Separate Channel Routing: Allows dedicated gain staging, equalization, and processing for each handheld transmitter when connected to separate channels on a mixing console or multi-channel PA amplifier.
- Mixed Channel Routing (OUT 1+2): Sums both microphone signals into a single 6.35 mm output, enabling connection to single-channel amplifiers or compact powered speakers without requiring an external mixer.
- Signal Dynamic Range: The receiver maintains a signal-to-noise ratio greater than 80 dB, total harmonic distortion (THD) under 0.5%, and an 80 dB dynamic range across a 50 Hz to 15,000 Hz frequency response.
Amplifier & Sound System Compatibility
The system is compatible with standard low-to-medium impedance unbalanced inputs across a wide range of PA equipment:
- PA Amplifiers & Boosters: Direct connection to standard 6.35 mm unbalanced microphone input ports matching 1 kΩ / 50 mV input sensitivity.
- Audio Mixers & Consoles: Interfaces with mono line/mic 6.35 mm jack inputs on analog and digital mixing desks.
- Active / Powered Speakers: Direct connection into active PA speakers equipped with 6.35 mm instrument or microphone input jacks.
RF & Environmental Operational Criteria
The AWM-495V2 operates on fixed quartz crystal-locked VHF high-band carrier frequencies with a frequency stability rating of ±0.005%. The transmitters emit FM (F3E) modulation with an RF output power under 15 mW maximum. Handheld transmitters feature internal antennas, while the receiver utilizes two rear-mounted telescopic antennas that require full vertical deployment and adequate physical clearance from RF-shielding metal structures to prevent carrier drops.
Electrical & Power Specifications
| Subsystem Component | Connector / Interface Type | Input / Operating Level | Power Requirement |
|---|---|---|---|
| AWM-495V2 Receiver | 6.35 mm (1/4") Phone Jacks (Ch 1, Ch 2, Mix) | 0–55 mV / 1 kΩ Unbalanced | 12V DC (via included 220–240V AC power adapter) |
| Handheld Transmitters (x2) | Dynamic Cardioid Cartridge (Internal Dipole) | 50 Hz – 15,000 Hz Audio Response | 3V DC (2 x 1.5V AA pencil cells per transmitter) (they are not included) |
Each handheld microphone requires 2 x 1.5V AA pencil cells (they are not included) with an operating current consumption of ≤100 mA. The receiver operates on 12V DC derived from the supplied 220–240V AC adapter.
