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 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.
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.
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.
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./p>
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.
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.
