FX series digital frequency shifter can effectively suppress howling, expand the volume, ensure the quality of voice transmission, high fidelity, clear sound, greatly suppress the whistle, and can effectively prevent the audio equipment and speakers from being burned out. No setting, no debugging, simple and convenient operation, fully automatic operation mode.
●开机自检功能，开启电源后电平指示灯亮起5秒后熄灭。
●自带防啸叫切换开关，可灵活运用于各种场合需求。
●配备信号过载指示灯，当PRESENT灯亮起，表示应调低输入电平，可有效地避免信号过载导致失真。
●具有48V幻象电源供电切换开关，根据产品需求随意选择。
●卡龙输入和6.3输入可并存，支持4+4路音频输入，3路音频输出。
●根据配套系统主控机的工作模式和输入电平增益，即可全自动适应声学环境。
●配备专业高速浮点数字信号处理器和自适应反馈（AFC抑制算法，整个系统会额外收获5-10dB的增益）。
●可连接外置232端口，配有专业PC调试软件，免驱动即插即用。方便快捷。
●与此移频设备搭配使用，拾音距离可在原基础上增加30-60CM。
●可兼容无线会议系列、无线系统系列、有线系统系列等会议话筒。
●power-on self-test function, after the power is turned on, the level indicator lights up for 5 seconds and then goes out.
●It comes with an anti-whistle switch, which can be flexibly used in various occasions.
●Equipped with a signal overload indicator, when the PRESENT light is on, it means that the input level should be lowered, which can effectively avoid signal overload causing distortion.
●It has a 48V phantom power supply switch, which can be freely selected according to product needs.
●XLR input and 6.3 input can coexist, support 4+4 channel audio input, 3 channel audio output.
●According to the working mode and input level gain of the main controller of the supporting system, it can automatically adapt to the acoustic environment.
●Equipped with professional high-speed floating-point digital signal processor and adaptive feedback (AFC suppression algorithm, the whole system will gain an additional 5-10dB gain).
●Can be connected to external 232 ports, equipped with professional PC debugging software, plug and play without driver. Convenient.
●Used in conjunction with this frequency shifting device, the pickup distance can be increased by 30-60CM on the original basis.
●Compatible with wireless conference series, wireless system series, wired system series and other conference microphones.
