The Azden i-Coustics PRO-XD is an easy to use and affordable digital wireless lavalier microphone system for camera mounting and mobile video applications. Its compact and lightweight design is a great solution for capturing au.dio on the go. Perfect for video production, electronic ne.ws gathering and even mobile devices, the PRO-XD includes an adapter cable for compatibility with headset inputs on most modern smartphones and tablets Utilizing digital wireless technology, the PRO-XD operates in the 2.4GHz range which is completely free of TV and radio interference. The PRO-XD out performs similarly priced VHF systems with better than CD quality digital au.dio and delivers dependable operation out to a distance of 100 feet or beyond with direct line of sight. Set up is a breeze with automatic syncing between receiver and transmitter. Internal, rechargeable lithium-ion batteries provide long lasting operation and easy charging via USB.Designed to deliver high-fidelity au.dio, the receivers high gain output with volume control alleviates noise and hiss produced by low-quality camera preamps and eliminates the need for big adjustments in post production. The PRO-XDs transmitter uniquely includes an auxiliary line input, allowing you to wirelessly transmit any stereo, line level au.dio source and mix it with the microphone source if desired.With its incredibly small form factor, the PRO-XD is the first viable digital wireless au.dio solution for use with action cameras, such as the popular Hero series from GoPro (3rd party cable may be required for connection).The complete PRO-XD system includes the transmitter, receiver and specially designed lapel microphone as well as an adapter cable for mobile devices, an au.dio output cable, USB cable and AC adapter for charging.The PRO-XD is part of the Azden i-Coustics sub- , which means it is compatible with many different mobile devices. The PRO-XD can be connected to a mobile device using the included TRRS au.dio adapter cable, which plugs into the connecting devices headset input.Features:- Operates in 2.4 GHz wireless range- High gain output alleviates noise and hiss produced by low-quality camera preamps- Mobile device compatible- Auto sync between transmitter and receiver- Operating range of 35 meters or more in optimal conditions- Rechargeable internal batteries- Wide frequency response and low internal noise- Headphone monitor output- Line in aux inputPRO-XD- Operating Freq.: 2.4GHz ISM Band- Dynamic Range: 90dB- Signal-To-Noise: 80dB- Operating Range: 35m typical; up to 120m in ideal conditions- Freq.
