Description
Product Description: Standard chassis design, 1U aluminum alloy panel.
Amplifier Type: Class D power amplifier circuit design, low loss, and amplification efficiency of over 90%.
Digitalization: Highly integrated digital circuitry significantly improves stability and energy efficiency.
Small Size: Uses highly integrated digital chips instead of traditional transformers, resulting in a smaller size, reduced to a 1U panel, and lighter weight.
Clean Junction: Eliminates high-frequency oscillations and common-mode noise generated by traditional toroidal transformers, eliminating current noise from coupling, crosstalk, and electromagnetic radiation. The digital circuitry also provides strong anti-interference capabilities.
Professional noise gate control of the output signal ensures quiet background music.
Intelligent power management function: automatically enters standby mode when there is no signal, with standby power less than 3W, ensuring 24/7 uninterrupted operation.
One master volume control knob controls the volume of all lines and microphones. Two parametric equalizer knobs adjust bass and treble to improve sound quality.
Each line input volume and each microphone volume has an independent control knob.
Features MP3 playback control buttons: Bluetooth, radio, and USB/SD card playback; a small screen displays playback status.
Includes an MP3 player, capable of playing audio programs from USB flash drives and SD cards, supporting up to 32GB.
Includes FM radio function, capable of receiving radio programs at frequencies of 88-108MHz.
6 audio input channels: 3 standard line inputs and 3 standard microphone inputs.
1 audio output channel, which can be looped to the audio input interface of another amplifier.
MIC3 has the highest priority; it automatically mutes upon signal input. A junction FET performs priority switching to ensure no signal distortion during mute.
6-channel zone control buttons and indicator lights; the indicator light for a zone illuminates when it is activated.
70V and 100V constant voltage outputs, 4-16Ω constant impedance outputs, and six-channel zone constant voltage outputs (CH1-CH6).
Real-time operating status indicator lights: 5 signal indicators, 1 protection indicator, 1 distortion indicator, and 1 power indicator.
Line safety operating area protection ensures safe operation of the output load under any harsh environment, including short circuits and overloads.
Comprehensive temperature protection: When the machine temperature rises, the temperature servo circuit accelerates the fan, resulting in low fan noise.
Peak negative feedback protection effectively protects the power amplifier in case of signal distortion, surges, or severe line voltage overvoltage.
Integrated crossover tone compensation circuit corrects high-frequency losses caused by line transformers, resulting in a flat signal spectrum curve on the line voltage and a beautiful tone.
High octave band bass cutoff circuit: Employing tone-compensated low-cut technology, it removes potentially hazardous ultra-low frequency components without sacrificing sound quality, ensuring safe operation of the boost system.
