Wireless Microphone

— 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, sturdy structure and anti-harmonic interference effect, can resist  contact 4kV strong magnetic interference, air gap 6kV electromagnetic interference.

— Receiver with segment code LCD screen, real-time display of system information, with independent  channel operation buttons, with shuttle control knob, easy to operate. 

— The receiver built-in DSP digital audio processing software, can realize the channel automatic gain,  automatic feedback suppression, automatic equalization adjustment, automatic mixing and other functions.

— The receiver provides independent audio channel output interface and mixing output interface, mixing  output interface with balanced output and unbalanced output, can be adapted to a variety of post-level  equipment 

— The receiver provides RS485 communication interface to support access to the central control system,  visual media interactive system, intelligent conference management platform; support remote access to  system information, system status(frequency, volume, power, signal, etc.); support remote modification of  the frequency, modification of volume 

— The receiver provides USB interface, connect to PC computer, can realize PPT page flip function(this  function needs transmitter support). 

— The receiver has 2-channel antenna interface, connecting high-performance rod antenna. Antenna  interface with antenna power supply and signal amplification compensation function, can be active antenna  power supply(active antenna needs to be purchased separately). Provide antenna extension base, can be  used for cabinet installation when the antenna leads out to avoid cabinet metal shielding. 

— The receiver has 2-way antenna cascade interface, supporting antenna cascade. No need to configure  antenna distributor, realize multiple receivers cascade, use a common antenna system. Unlimited number of  cascade. 

— Adopt wireless transmission technology, support 48kHz audio sampling frequency, realize lossless audio  transmission, wireless signal straight-line barrier-free working distance up to 100 meters.

— Adopting internal CRC checksum, 32-bit encrypted word transmission for audio and data to ensure the  privacy of communication and avoid eavesdropping and malicious interference. 

— The receiver adopts true diversity type large dynamic receiving circuit, which greatly improves the effective  signal receiving range and stability, and supports up to 100 communication frequency points to choose  from. 

— The receiver has built-in wireless frequency sweep software, supporting one-key automatic frequency  sweep. The system automatically detects the current wireless environment and selects clean frequency  points to improve communication stability. 

— The receiver supports one-key lock/unlock function, which can prevent personnel from misoperation  leading to setting changes. 

— The receiver and transmitter use infrared emission to realize automatic frequency matching, microphone  automatically matches with the conference system, supporting a variety of forms of wireless microphone  use. 

— Adopting safe and intelligent adapter power supply, conforming to safety certification, suitable for use in  various regions(adapter connector depends on the region). 

— The transmitter has built-in wireless microphone embedded software, with wireless speech, infrared  frequency pairing, work status display and other functions. 

— The transmitter has a power-down detection and protection circuit, which can obtain real-time power  information of the transmitter and realize the low battery reminder and low power consumption protection  function. 

— Rectangular Columnar Short Wireless Microphone. 

— The fixed rectangular columnar short microphone design for stable and reliable connection, with adjustable  angle. The microphone is made of metal, with internal cavity pickup design and built-in windproof cotton  for clearer sound pickup. Base with LCD display, side with PPT page turn button, built-in lithium battery. Handheld Wireless Microphone 

— Compact handheld microphone design with metal hexagonal mesh cover, effectively prevent the  microphone from rolling and falling. The end of the anti-grip design, effectively preventing the wireless  signal shielding caused by the wrong hand position. Microphone with LCD display, real-time display of  frequency information, power information, etc.
