Audibax Missouri 2000 (Range A) - Handheld Dual VHF Wireless Microphone System with Diversity Receiver

Audibax Missouri 2000 (Range A) - Handheld Dual VHF Wireless Microphone System with Diversity Receiver

The Audibax Missouri 2000 (Range A) is a VHF wireless microphone system designed for events, permanent installations, and professional rentals where reliability and ease of use are paramount. It includes two handheld microphones with cardioid dynamic capsules and a dual receiver with diversity antennas , which improves signal pickup and reduces multipath loss. It offers an approximate range of up to 80 meters under optimal conditions and clear audio quality thanks to its 40 Hz to 18 kHz frequency response , signal-to-noise ratio > 103 dB , and harmonic distortion < 0.5% . The receiver provides XLR and 6.35 mm jack outputs for quick integration with mixing consoles, powered speakers, or installed systems.

This model operates in the A range (179.300–188.100 MHz) , with quartz locking technology that guarantees frequency stability of ±0.0005% . Each microphone has an on/off switch and mute button , a display indicator, and is powered by two AA batteries , while the receiver operates on 230V . RF/AF indicators and independent volume controls per channel facilitate monitoring during live performances.

Main features

• Handheld dual VHF system: 2 microphones + 1 dual receiver.
• Range A: operating frequencies 179,300–188,100 MHz.
• Diversity antennas: greater link stability and less sensitivity to reflections.
• Cardioid dynamic capsule: directional pattern that helps minimize coupling and ambient noise.
• Frequency response: 40 Hz – 18 kHz for clear and full-bodied vocals.
• Clean audio: signal-to-noise ratio > 103 dB and THD < 0.5%.
• Stability: quartz control with ±0.0005% variation.
• Coverage: up to approximately 80 m (favorable conditions, line of sight).
• Controls and indicators: displays on microphones, RF/AF indicators and independent volumes on the receiver.
• Connectivity: XLR and 6.35 mm jack outputs (mixed output) for quick connection.
• Power supply: microphones with 2×AA; receiver at 230V.
• Finish: black color, construction designed for frequent use at events.

Product benefits

• Signal stability: the Diversity system reduces dropouts and improves reception in busy environments.
• Consistent sound: The cardioid capsule and 40 Hz–18 kHz response provide defined and controlled vocals.
• Simple operation: clear controls, RF/AF indicators and standard outputs for quick setup.
• Installation flexibility: balanced XLR and 6.35 mm jack outputs for different audio configurations.
• Efficiency in events: volumes per channel and Mute function on each microphone to manage turns and interventions.

Use cases

• Events and rental: weddings, congresses, fairs, presentations and traveling shows.
• Fixed facilities: multipurpose rooms, cultural centers, gyms, school auditoriums and houses of worship.
• Education and business: masterclasses, seminars, hybrid meetings with voice reinforcement.
• Leisure and hospitality: karaoke, entertainment and microphones for presenters.

Frequently Asked Questions

• What's the difference between Ranges A and B? They are variants that operate on different VHF sub-bands. Range A operates between 179.300 and 188.100 MHz; Range B uses other frequencies within VHF. Choose the range based on your usage environment and spectrum availability in your area.
• What is the battery life of the microphones? It depends on the type of AA batteries used and the usage. As a reference, the system is optimized for several hours of continuous use with new alkaline batteries.
• How do I connect the receiver to my equipment? Use the XLR outputs for balanced connections to mixers/preamps or the 6.35 mm jack output (mixed) for compatible line inputs.
• Can both microphones be used simultaneously? Yes. Each channel is independent, with its own volume control and RF/AF indicators.

Integration tips and best practices

• Place the receiver antennas in a vertical and clear position, avoiding nearby metal surfaces.
• Look for line of sight between microphones and receiver to maximize coverage and stability.
• Adjust the gain on the receiver and the mixer to avoid saturation; use XLR if you need long cable runs.
• Replace the batteries before each event and use quality alkaline or rechargeable batteries.
