SL4300 Digital Amplifier
Features
▼This series of power amplifiers meet your ideal requirements.A series of power amplifier with full protection function.It includes DC overload short circuit, overheating, ultra high frequency, limiter and other functions.
▼High precision machining and painting process make the structure of power amplifier firm and elegant appearance.Deformation resistance and impact resistance are deliberately used to deal with drag wear and vibration of cold rolled steel plate.Low noise 3-speed fan, good thermal stability.
▼This series also uses the latest digital power amplifier circuit, power amplifier efficiency of more than 95%, small volume, high power density, high fidelity sound.The latest digital circuit topology technology makes the output waveform of power amplifier smoother, burn-free, frequency response smoother, high-frequency burn-free and sound more delicate under the same test conditions
Applications:
Conference room, multi-function hall, multimedia classroom, medium and small banquet hall
