Technical Specifications

Features of Wireless Microphone GX-U402-G/GX-U404-G

  • One receiver can be equipped with 2 hand microphones (GX-U402A-G)/rectangular columnar short microphones (GX-U402D-G)

  • One receiver can be equipped with 4 hand microphones (GX-U404A-G)/rectangular columnar short microphones (GX-U404D-G)

  • The receiver adopts metal shell design, segmented LCD displays system information, and each channel is set with independent buttons to facilitate user operation, with total volume control knob

  • It adopts full digital wireless communication technology, which can resist interference and

  • multipath fading, and is not affected by light and infrared. It can be used stably in WLAN environment

  • The receiver adopts true diversity large dynamic receiving circuit, and supports 48kHz audio sampling frequency and up to 100 communication frequency points

  • Internal CRC is adopted, audio and data are transmitted by 32-bit encrypted word to ensure the privacy of communication and avoid eavesdropping and malicious interference

  • Adopt high performance communication antenna, and support antenna extension. The straight-line barrier free working distance of wireless signal is 100 meters

  • The receiver supports antenna cascade, and multiple receivers can share a set of antenna system, which is convenient for project installation and wiring

  • The receiver supports the power supply function of antenna amplifier, which can supply power for the specified active antenna, reduce the intermediate equipment of the system and improve the convenience

  • Single or mix output in each channel, independent electronic volume adjustment in each channel

  • The mixed output has balanced output and unbalanced output, which can be flexibly adapted to various post-stage equipments

  • The receiver supports one key automatic frequency sweeping function. The system automatically detects the current wireless environment, and selects clean frequency points, improving the communication stability

  • The receiver supports one key lock / unlock function, which can prevent the setting change caused by personnel misoperation

  • It is powered by safe and smart adapter, which meets the safety certification and is suitable for various regions (adapter connector depends on the regions)

  • The receiver provides USB interface to connect with PC to realize PPT page turning function (the function depends on the version)
