Audix AP42OM5B Dual-Channel Wireless System

Dual Channel Wireless Handheld Microphone System for Live Performance

The Audix AP42 OM5B is a dual-channel UHF wireless microphone system built for performers and production teams who need dependable signal stability and focused vocal clarity. This system includes the R42 dual-channel diversity receiver and two H60 handheld transmitters fitted with OM5 hypercardioid dynamic capsules. Designed for concerts, houses of worship, corporate presentations, and event production, it delivers consistent wireless performance with professional sound quality across demanding stage environments.

UHF Diversity Receiver with Fast Setup and Stable Signal

Operating in the 554 to 586 MHz frequency band, the R42 receiver provides 32 MHz of tuning bandwidth and 106 pre-coordinated frequencies for efficient channel selection. One-touch auto scan quickly locates a clear frequency, while infrared sync instantly pairs the receiver with each handheld transmitter. The true diversity design with dual antennas helps maintain stable RF performance and minimizes dropouts, even in crowded wireless environments.

OM5 Hypercardioid Capsule for Isolated Vocals and High SPL Handling

Each H60 transmitter features the OM5 dynamic capsule with a tightly controlled hypercardioid pickup pattern. This design focuses on the voice while rejecting off-axis stage noise, monitors, and instruments. The OM5 delivers clear midrange articulation, controlled high-frequency presence, and handles sound pressure levels exceeding 144 dB without distortion. This makes it a strong choice for high-volume stages, powerful vocalists, and situations requiring maximum feedback resistance.

Professional Handheld Transmitters with Onboard Controls

The H60 handheld transmitters are constructed with durable metal housings and a slim, balanced profile for comfortable extended use. A soft mute switch allows quiet on and off operation during performances. The high-contrast LCD screen displays group, channel, frequency, and battery status for quick monitoring. Adjustable AF gain settings and selectable RF output power allow system optimization based on venue size and stage layout.

Rackmount Receiver with Flexible Connectivity

The R42 receiver is housed in a 19-inch rackmount chassis and includes BNC cables for front-mount antenna configuration. Balanced XLR and unbalanced 1/4-inch outputs allow seamless integration with professional mixing consoles and PA systems. The front-panel LCD provides real-time RF and AF signal strength, frequency data, and battery indicators, giving audio engineers clear system visibility during setup and performance.

Expandable Wireless System for Multi-Mic Applications

The AP42 OM5B supports multiple system deployments, allowing up to eight systems to operate simultaneously for a total of 16 wireless microphones. Adjustable AF and RF gain, a ground-lift switch to reduce hum, and selectable lock functions help ensure reliable operation in complex live sound setups. Included accessories such as antennas, rackmount hardware, audio cables, and power supply make the system ready for immediate installation.
