2.4G Wireless Speaker Solution

The 2.4G wireless speaker solution offers one-to-many transmission, synchronized left and right channel audio transmission, and low-latency, high-fidelity wireless audio. Its modular design, with optional internal or external antennas on the PCB board, saves manufacturers productization time. It supports options like one transmitter to one receiver (stereo dual-channel transmission) and one transmitter to two receivers (separate reception for left and right channels).

  • Automatic channel allocation

    Pre-set 20 channels for one-to-many and multiple simultaneous use

  • Stereo dual-channel

    Sampling rate: 44.1K, Resolution: 16 bits

  • Audio algorithm

    Utilizes A-LAW

  • Communication protocol

    Uses A-FFC

  • Strong anti-interference capability

    Digital processing for audio transmission

  • Automatic mute

    In cases of poor channel quality and high error rates

  • Channel switching follows

    Transmission channel switches, and reception follows automatically

  • Wireless Transmission Range

    Over 30 meters (in open space)
