the main panel with metal wire drawing process, with the function of six key, appearance design of high-grade, high-tech feeling
lines and shell are strengthened and the ground wire connection, ensure a 8000 v antistatic ability, accord with national standard GB/T17618-1998
FM radio wireless system different from the traditional methods, this system USES digital encryption transmission, voice and control channel are encrypted using high-intensity, can effectively protect the customer's conference contents were not malicious eavesdropping.Make client meetings more secure and confidential.
with high and prevent the noise reduction circuit design, and adopting new anti noise to high sensitivity condenser microphones core, make meeting quality to achieve high fidelity sound reduction, intelligent digital audio algorithm, clear timbre bright and beautiful, smooth transmission, and audio delay is extremely low, can be good support after class feedback inhibition, etc.
new concept of anti-electromagnetic interference circuit design, put an end to mobile phones and other electronic products of electromagnetic interference
control and audio signal using high frequency signal wireless communication, avoid setting microphone cable, installation is simple convenient and flexible
high pure and fresh and LCD display, menu hierarchical design, operation simple and convenient.It has many functions such as power display and undervoltage warning, frequency channel and signal indication.
microphone have the functions of automatic switch machine, the host can open microphone after out-of-the-box, host each receiver will automatically shut down after shutdown.And the microphone is in a high blocking state after shutdown, no impact on the battery.
host and volume control function.
chairman microphone and on behalf of the receiver can replace each other, the host can be automatically memory and tracking, chairman of the receiver.
host channel selection and user-generated channel function, to adapt to the wireless environment.
system ID recognition function, different system available ID.
this system more energy conservation and environmental protection, the system frequency utilization ratio is high, the channel multiplexing technology, no matter how many microphones are only competing only occupy four of the radio frequency.Frequency utilization is becoming more and more important at a time when frequency resources are becoming increasingly scarce.At the same time, most microphones in the application system are in the state of low power consumption without speech, and the overall power consumption is lower than that of traditional wireless microphones.
every system can support a chairman and an infinite number of representatives, speaking at the same time the representative number to be chairman of the 1 and 3.
system has the control interface, control switch a sensitive, accurate and is not affected by phone number.This system can open 4 audio channels at the same time, and the number of MCS in fifo mode is not limited.System support multiple speech modes, FIFO FIFO, chairman dedicated mode.
systems support video tracing with RS422 / RS485 camera control interface, support 64, camera preset support VISCA with PELCO - D agreement.Can independently control the camera, or with the rear camera control host connection.
this system can be connected to the computer or remote control device, and achieve a more flexible operation control digital control technology, the receiver only occupy four sound point again and again, avoid the occurrence of string frequency phenomenon.It solves the problem that traditional one tow four UHF wireless conference cannot solve the problem that multiple wireless conference microphones can be used simultaneously in the same occasion.
