Audix R42 (A-Band) - Performance Series Dual Diversity Wireless Receiver
The Audix R42 is the heart of a professional wireless system designed for those who cannot afford any downtime on stage or in fixed installations. Part of Audix's acclaimed Performance Series , this dual-channel receiver offers a robust and efficient solution for managing two microphones simultaneously from a single metal chassis unit, optimizing rack space and simplifying technical setup.
This specific model operates in the A-band (522 MHz - 554 MHz) , a balanced frequency range that offers excellent signal penetration and stability. Its Diversity receiving technology ensures the system automatically switches between antennas to maintain the cleanest possible signal at all times, eliminating dropouts and static interference that often ruin live performances. Thanks to its 32 MHz tuning bandwidth, the R42 is capable of operating reliably in congested RF environments.
Ease of use is one of the R42's strongest points. With its auto-scan and infrared synchronization features, the system does all the heavy lifting for you: it finds a free channel and pairs the transmitter in seconds. Its durable metal construction and included rack-mount kit make it a sound investment for rental companies, auditoriums, and demanding tours.
Main features
-
Dual Channel Design: Allows two transmitters (handheld or bodypack) to operate independently with a single receiver, saving space and power connections.
-
Wide spectrum tuning: It has a bandwidth of 32 MHz and 106 pre-coordinated frequencies to always ensure a free channel.
-
One-Touch Setup: The Auto Scan and Sync systems allow you to configure the equipment by pressing a single button, ideal for quick changes on the fly.
-
High-contrast LCD display: Provides clear readings of radio frequency (RF) and audio (AF) levels, transmitter battery status, and operating frequency, even in dark scenarios.
-
Professional outputs: It has balanced XLR outputs and individual unbalanced 6.3 mm jack outputs for each channel.
-
Complete hardware: The chassis is metal and comes ready for 19-inch rack mounting, including BNC cables for front antenna mounting.
Benefits of the system
The Audix R42 is designed to simplify the lives of sound engineers and performers. By integrating two receivers into a single 1U unit, it reduces cabling complexity and optimizes rack space. Audio quality is transparent and faithful, preserving the natural timbre of the voice or instrument thanks to low-noise internal circuitry.
Furthermore, its ability to work with up to 8 simultaneous systems (16 channels in total) makes it scalable. If your project grows, you can add more R42 units without worrying about immediate spectrum saturation, provided the frequencies are properly coordinated within the available range.
Use cases
-
Fixed installations: Ideal for churches, conference centers, and university auditoriums that require multiple microphones operating simultaneously.
-
Live events and tours: Its metal chassis withstands the rigors of the road, making it perfect for bands that carry their own sound equipment.
-
Corporate presentations: The reliability of the Diversity system ensures that the CEO's or presenter's speech is never cut off.
-
Theatres and broadcast: Thanks to its quiet operation and antenna mounting options, it integrates perfectly into production environments.
Frequently Asked Questions
-
Does this product include microphones?
No, this item is the R42 receiver (with mounting kit) . It is the core of the system. You will need to purchase the A-Band compatible handheld (H60) or bodypack (B60) transmitters separately.
-
What does "A-band" mean?
This refers to the radio frequency range in which the equipment operates, specifically from 522 MHz to 554 MHz. Make sure the transmitters you use are also A-band.
-
Can I mount the antennas on the front of the rack?
Yes, the kit includes the BNC cables and the necessary holes in the rack ears to move the antennas to the front panel, improving reception when the equipment is boxed in.
-
What is the maximum range?
Under ideal line-of-sight conditions, the system offers an operating range of up to 90 meters (approximately 300 feet).
