Multi Zone Mixer Amplifier

● Standard 19-inch rack design, black aluminum brushed panel, laser cutting chassis, professional appearance and high grade;

● Six-way zone output (constant voltage 100V output), each zone can adjust the volume independently;

● Each zone LED dynamically displays the zone volume, and the gear switch operation is convenient and easy to use;

● Embedded player, 2.5-inch high-brightness LCD display, large font display of the playback track name, playback progress and other mode states, support U disk and TF card access playback, and provide infrared remote control for user operation;

● Support customized display of product LOGO and Bluetooth name;

● MP3 player, support MP3, WMA, WAV, APE, FLAC and other format decoding, high-fidelity sound quality;

● Support mobile phone Bluetooth connection, and can play programs on demand through the mobile phone player;

● The shuttle key adjusts the MP3 volume, and the screen displays the volume value intuitively;

● Four-way signal input (two-way microphone input, two-way line input);

● 1-channel audio signal auxiliary output interface, which can be expanded to connect to an external power amplifier, standard lotus seat interface, convenient wiring;

● Independent volume adjustment for each input channel;

● LED level display: can display output signal strength, distortion status, protection, over-temperature indication, easy to observe the working condition of the machine;

● Three-level priority circuit, MIC1 has the highest priority level, AUX1 has the second priority level, MIC2, AUX2 have the third priority level;

● AUX1 has an amplification adjustment knob, which is convenient for connecting to sound sources of different amplitudes (30mV-1200mV);

● AUX1 has a priority selection switch, ON means AUX1 has priority function. OFF means AUX1 has no priority function;

● Excellent noise control, comparable to professional-grade amplifiers;

● Adopting the most advanced transformer design in the industry, the amplifier output is cut off when the internal temperature of the transformer exceeds 105 degrees, which better protects against overload;

● Adopting imported power tubes, the output power is strong; wide bandwidth, low noise, high fidelity, perfect restoration of human voice and music;

● Comprehensive protection circuit: DC protection, if there is DC voltage at the output end of the amplifier, the output is immediately cut off to protect the speaker; short circuit protection: if the load is short-circuited, the output is immediately cut off, and the fault is automatically restored; thermal protection, if the temperature inside the amplifier exceeds 70℃, the power limit is activated; if it exceeds 85℃, the output is cut off;

● High-octave bass removal circuit, using low-cut technology with tone compensation, removes ultra-low frequency components with safety hazards without losing sound quality, ensuring the safe operation of the boost system;

● Peak negative feedback protection, when the signal is distorted, impacted, or the line voltage is severely over-voltage, it can effectively protect the amplifier;

● Independent soft-start protection circuit to prevent damage to the equipment caused by high current at startup;

● Professional voltage limiting circuit can detect output signal clipping caused by various situations such as reduced power supply voltage, heavy load, excessive input signal, and increased amplifier temperature, and automatically correct it to avoid output signal distortion, resulting in broken sound, and damage to the amplifier and speaker;

● Tunnel-type air duct, forced air cooling from front to back, with intelligent fan speed management function, low speed operation at room temperature, fan speed acceleration at room temperature, power limit start, fan full speed rotation and cut off amplifier output when the temperature inside the amplifier exceeds 70℃, and the temperature indicator light is turned on to alarm;

● Support 1-way selectable voltage (70V/100V) or fixed resistance 4-16Ω output, so that this machine can be used as a broadcasting system or to drive professional-grade speakers;

● Professional modular circuit design to ensure reliable consistency of the product;

● High-strength thickened body to ensure that the product will not be deformed due to harsh transportation environment;
