Audix AP42OM2B Dual-Channel Wireless System

Dual Channel UHF Wireless Microphone System for Live Performance

The Audix AP42OM2B Performance Series wireless system is a professional dual-channel handheld microphone package designed for live vocals, houses of worship, corporate presentations, and conference environments. This system includes the R42 dual-channel UHF diversity receiver operating in the 554–586 MHz frequency band and two H60 handheld transmitters fitted with OM2 dynamic vocal capsules. It delivers dependable RF stability, strong signal clarity, and straightforward setup for performers who need reliable wireless performance.

R42 Dual Channel Diversity Receiver with 32 MHz Bandwidth

The R42 receiver offers 32 MHz of wideband tuning across 106 pre-coordinated frequencies in the 554–586 MHz spectrum. One-touch auto scan identifies clear channels quickly, while infrared sync pairs the transmitters instantly for efficient configuration. The true diversity design improves signal reliability and minimizes dropouts in demanding RF environments. A high-contrast LCD screen displays RF and AF levels, frequency, group, channel, and battery data, giving operators full system visibility. Balanced XLR and 1/4 inch outputs provide flexible integration with professional mixing consoles and PA systems, and the 19-inch rackmount chassis supports clean installation in touring or permanent setups.

Two H60 Handheld Transmitters with OM2 Hypercardioid Capsules

Each H60 handheld transmitter is equipped with the OM2 dynamic vocal capsule, known for its controlled low-end proximity effect and focused midrange presence. The hypercardioid polar pattern enhances off-axis rejection, reducing stage bleed and feedback while maintaining strong vocal clarity. The OM2 capsule uses VLM diaphragm technology to deliver detailed, accurate voice reproduction and can handle sound pressure levels up to approximately 140 dB without distortion. The slim metal housing provides durability and comfortable handling for extended performances.

Advanced Control Features and Long Operating Time

The H60 transmitters offer selectable RF output power at 10 mW or 30 mW and include three adjustable gain settings to match various vocal styles and performance levels. A high-contrast LCD provides quick access to frequency, group, channel, and battery status. Each transmitter operates up to 14 hours on two AA batteries, supporting long events and stage productions. The soft-touch mute switch allows silent on/off control, and a selectable lock feature helps prevent accidental changes during live use.

Scalable Wireless System for Multi Channel Applications

The AP42OM2B system supports up to eight systems operating simultaneously, allowing as many as 16 wireless channels in coordinated setups. The receiver includes an internal antenna combiner and ships with antennas and BNC cables for convenient front-mount configuration. Adjustable RF and AF levels help fine-tune performance, and a ground-lift switch assists in minimizing hum or unwanted noise. With operating distances of up to 300 feet under typical conditions, this wireless microphone system is well suited for larger venues and stage environments.

Reliable Wireless Solution for Vocalists and Presenters

Designed for singers, public speakers, worship leaders, and corporate presenters, this dual handheld wireless microphone system combines consistent RF performance with professional audio quality. Whether installed in a rack for permanent use or deployed for touring applications, the AP42OM2B provides practical control, dependable signal transmission, and strong vocal clarity across demanding live environments.
