Features

• This system Integrated Transmitter with digital wireless audio transmission, which makes its sound quality and stability is far better than analogue wireless transmission. The transmission frequency is around 900Mhz, which is more penetrating than Bluetooth, Wi-Fi and 2.4G frequency. And the transmission distance is longer. The main advantage of wireless transmission is, it reduces the cost of laying cables and the cost of time. The system host is convenient to move. Through the double recognition of frequency and code between the host and each speaker, the non-interference and stable operation of multiple systems can be guaranteed. Even when multiple systems are very close and intersecting with each other, there won’t have any mistake. The system is convenient and fast for frequency and code matching, which can be completed in one time.
• This system host can integrate with following devices: Bluetooth player, MP3 player (supports USB and TF card, supports MP3, WMA, WAV, APE, FLAC and many other format decoding), digital recorder (long recording time, high quality sound, 8G USB for store recordings up to 160 hours), preamplifier (mixing, tone adjustment, microphone priority), karaoke reverberator (reverberation suppression and removing original voice), conference desktop microphone (professional gooseneck microphone rod, with LED lights), digital wireless transmitter and many other audio equipment.

• The system is integrated with protective wall-mounted speaker. The speaker is with innovative design and structure. It has the advantages of high sensitivity, wide frequency response and small distortion level, so it is suitable for making voice broadcasting and background music broadcasting. There is no limit to the number of speakers that can be connected, only the transmission distance is limited (the visual distance 30 meters for radius).
