Usb transmitter allows connectivity between your computer audio sound to the Power Bird. Thanks to the chosen Kleer® wireless transmission system, the sound of the computer reaches the Power Bird amplifier with sound quality strictly identical to CD quality (with files in CD format WAV or AIFF type). The transmission is full digital: no distortion or bandwidth limitation come to decrease music signal quality. Able to transmit any audio files supported by computer (AAC, MP3, WMA, OGG, Apple Lossless, FLAC...), it can transmit web radios, game or video soundtracks and any sound from your computer.
