MX-2 Mini to XLR Stereo Y Cable

Male 3.5mm stereo to dual male 3-pin XLR cable.


The PRO-XR is a new kind of 2.4 GHz digital wireless microphone. Using several new technologies, it avoids the line-of-sight dependency and congestion problems that plague traditional 2.4 GHz wireless, resulting in an extremely reliable wireless microphone.

Easy-to-use, compact and lightweight, the PRO-XR is perfectly suited for video creators of all types. Whether you shoot with a DSLR camera, mirrorless camera, cinema camera or mobile device, the PRO-XR can deliver high-quality and dependable wireless audio for your videos.

Frequency Spectrum Auto-Scan

Once powered on, the PRO-XR automatically scans the 2.4 GHz frequency spectrum and selects the best available frequencies to use for its connection, thereby avoiding interference-prone frequency bands.

Automatic Interference Avoidance

The activity of 2.4 GHz devices in a given environment can change frequently and rapidly. That is why the PRO-XR constantly monitors this range and automatically and seamlessly changes its transmission to use different frequencies when it detects the possibility of interference.

Signal Redundancy Technology

Further fortifying the system’s resistance to interference, PRO-XR employs Azden’s proprietary Signal Redundancy Technology, in which the transmitter sends two copies of its signal to the receiver at all times, each on a different frequency. If the system predicts interference of the primary signal, it will instantly switch to using the secondary signal without any interruptions.

Adjustable Transmission Power

Change the transmission output power of the transmitter to adapt to challenging environments. Use the default 20 mW setting for optimal battery life and excellent performance in most situations. Optionally increase the output power to 50 mW or 100 mW for better performance at extreme distances, or to overcome line-of-sight obstructions and over-crowded Wi-Fi environments. Combining the 100 mW output with the use of the included high-gain transmitter antenna can extend the range of the system up to an incredible 500 feet!

External Antenna Design

While many other digital wireless systems are moving to under-performing internal antennas, the PRO-XR system (employs more reliable external antenna design and) comes with two interchangeable antenna options (for the transmitter): a flexible antenna for comfortable and inconspicuous wearing of the transmitter, and a high-gain antenna for increased performance especially at long distances and with line-of-sight obstruction.

Mobile Video Compatible

The PRO-XR is also compatible with smartphones and tablets out of the box. Easily mount the PRO-XR receiver to your smartphone with the included Smartphone Mount. A Lightning-to-headphone adapter cable is included for connection to iOS devices. A TRRS output cable is included for other devices with headphone jacks. No special apps are required to use the PRO-XR’s audio when shooting video on your mobile device.

Rechargeable Lithium-Ion Batteries

The built-in, rechargeable lithium-ion batteries provide up to 20 hours of run time on the receiver and 14 hours on the transmitter; plenty of power for a long day of shooting. Eliminates the hassles of single-use batteries and reduces e-waste. The system comes with a dual-USB charging cable and AC adapter.

Included Lavalier Microphone

The professional-grade, omni-directional lavalier microphone captures the full frequency range of 20 Hz to 20 kHz, ensuring crisp and clear recording of your subject’s voice. The angled 3.5 mm TRS plug allows compatibility with many other wireless systems and recorders.

Volume Control and Monitoring

The receiver includes a 3.5 mm headphone jack for monitoring, and a 6-step adjustable output gain control for optimizing audio levels with your camera.

Line-In Auxiliary Input

For extra flexibility, the transmitter allows for the connection of line-level audio devices via the 3.5 mm auxiliary input. This input can be connected to the output of an audio mixer, digital recorder or any other line-level source.

2-Year Warranty

The PRO-XR is backed by Azden’s 2-Year Warranty with online registration.

The receiver can be adapted for XLR audio inputs by using our MX-2 cable (be advised that many 3rd party solutions are not wired appropriately).
