product description:

Standard chassis design, 1U aluminum panel, user-friendly design, beautiful and practical.

6-channel audio input, including 3 standard line signals and 3 standard microphone signals.

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

The total volume adjustment knob controls the volume of all lines and microphones in a unified manner.

The two-parameter parameter balance adjustment knob is used to adjust the high and low to improve the sound quality.

MIC3 has the highest priority. The signal is automatically muted when the signal is input. The junction FET performs priority conversion to ensure that the signal is not distorted during the muting process.

The professional noise gate controls the output signal to ensure the squelch of background music.

70V, 100V constant voltage output, 4-16Ω constant resistance output.

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 this unit. Peak negative feedback can effectively prevent the signal line and voltage in any load environment No distortion, but no pressure.

The integrated cross tone compensation circuit corrects 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.

The high-octave bass cut-off circuit ensures the safe operation of the booster system. The use of low-cut technology with timbre compensation can ensure the removal of ultra-low frequency components that pose a safety hazard to the booster system without losing sound quality.

Built-in network IP decoding module, support TCP / IP, UDP, IGMP (multicast) protocol, realize the network transmission of 16-bit stereo CD sound quality and music signals.
