Features:

-Standard chassis design, 2U aluminum alloy brushed panel; user-friendly drawing design, beautiful and practical;

-Five-channel audio source signal input (three standard line signals, two standard microphone signals), and an independent knob for each channel to adjust the volume;

-1 channel audio output, can be looped to the next amplifier audio input interface;

-Comes with independent output of six-zone power, CH1-CH6 six-zone constant-voltage output, each zone switch selects output button, and each zone has LED on and off instructions

-With 100V, 70V constant voltage output and 4 ~ 16Ω constant resistance output;

-The volume of each input channel can be adjusted independently, and the treble and bass can be adjusted independently;

-MIC1 automatic mute has an adjustment switch, adjustable range: 0 to -30dB;

-4 unit LED level display, dynamic and clear;

-With perfect output short circuit protection and over temperature protection function;

-Professional noise gate control output signal to ensure the noise suppression of background music;

-Line safe working area protection to ensure that the output load works safely in any harsh environment such as short circuit and overload;

-Peak negative feedback protection, when the signal is distorted, shocked, or the line voltage is severely overvoltage, it is a severe safety test for the terminal speaker and the unit. Peak negative feedback can effectively prevent the signal line and voltage from being loaded in any load No distortion in the environment, but not over pressure;

-Integrated cross tone compensation circuit to correct the high frequency loss caused by the transformer between the lines, so that the signal spectrum curve on the line voltage is straight and the tone is beautiful;

-High-octave bass cut-off circuit to ensure the safe operation of the booster system. The low-cut technology with timbre compensation is adopted to ensure that the ultra-low frequency components that have potential safety hazards to the booster system are removed without losing sound quality;

-Very suitable for broadcasting in medium and small public places.
