Azden PRO-XR 2.4 GHz Wireless Microphone System

Azden PRO-XR 2.4 GHz Wireless Microphone System

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.

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.

The activity of 2.4 GHz devices in a given area 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.

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.

While many other digital wireless systems are moving to under-performing internal antennas, the PRO-XR system employs a 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.

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!

The included mount uses a spring-loaded clamp to tightly grip down onto almost any smartphone. It can accommodate phone widths from 2.4 in. – 3.3 in., making it compatible with even the largest smartphones (phablets) on the market today. Unlike many other phone mounts, ours is equipped with a cold-shoe slot, allowing you to mount a microphone, wireless receiver, or other accessories. The mount itself is mountable to any tripod or pole via a ¼”-20 threaded hole. Built to last, the mount is all-metal construction and quality tested to withstand over 6,000 pulls.

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.

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.
