Audix AP61SAX Single-Channel True Diversity Receiver

Professional Wireless Instrument Microphone System for Live Performance

The Audix AP61 SAX is a single-channel UHF wireless system built specifically for brass, woodwind, and other acoustic instrument applications. Designed for live stage, houses of worship, touring musicians, and broadcast environments, this package combines the R61 true diversity receiver, B60 bodypack transmitter, and ADX20i cardioid clip-on condenser microphone. It delivers stable long-range RF performance, detailed instrument capture, and fast system setup for performers who need mobility without sacrificing sound quality.

True Diversity UHF Receiver with 64 MHz Wideband Tuning

At the heart of the system is the R61 single-channel true diversity receiver operating in the 522 to 586 MHz frequency band. With 64 MHz of bandwidth and 207 pre-coordinated frequencies, the system is engineered to handle demanding RF environments. Up to 2560 tunable frequencies provide additional flexibility for frequency coordination. One-touch auto scan quickly finds a clear channel, while infrared sync pairs the transmitter instantly. With an operating range of up to 450 feet, this wireless instrument system supports large stages and performance venues with confidence.

Bodypack Transmitter Designed for Instrumentalists

The included B60 bodypack transmitter is compact, rugged, and built for professional touring use. It offers selectable mic or line level input and four adjustable gain settings to match a variety of instruments. RF output power can be set to 10 or 30 mW for optimized signal strength and battery efficiency. Powered by two AA batteries for up to 14 hours of operation, the B60 features a durable metal housing, secure belt clip, and soft mute switch for quick control during performance.

ADX20i Clip-On Condenser Microphone for Brass and Woodwinds

The ADX20i cardioid condenser instrument microphone is designed for saxophone, trumpet, trombone, and other acoustic instruments requiring accurate, detailed reproduction. Its pre-polarized condenser element provides a wide 40 Hz to 20 kHz frequency response, delivering natural tonal balance and clear transient response. The cardioid pickup pattern reduces off-axis noise and helps control feedback on loud stages. A shock-mounted gooseneck and integrated clamp allow secure instrument mounting and flexible positioning for consistent sound capture.

Professional Connectivity and System Control

The R61 receiver features a high-contrast LCD display showing RF and AF signal strength, frequency, group, channel, and battery status. Adjustable AF and RF gain controls allow precise system optimization. Balanced XLR and 1/4-inch outputs provide compatibility with professional mixing consoles, PA systems, and installed audio systems. A selectable ground-lift switch helps eliminate hum from ground loops. Lock functions on both receiver and transmitter prevent accidental changes during live performance.

Ready for Stage and Installation Applications

The AP61 SAX includes antennas, BNC antenna cables, audio cable, batteries, power supply, and rackmount kit for immediate deployment. The receiver supports front or rear antenna mounting for flexible rack integration. Whether used in concert venues, churches, school auditoriums, or corporate events, this wireless clip-on instrument microphone system offers dependable RF stability, detailed audio performance, and professional-grade build quality.
