Professional Power Amplifier
DIGITAL POWER AMPLIFIER
Scope of application:
Meeting, theatre, auditorium, multi-function hall the places where requires high level voice.
TFT color display in Chinese and English
Stable power switch
Multiple import filter capacitance
1. The case is made of high strength iron plate die-cast, which is durable.
2. The circuit uses precision of two-stage Class H type.
3. Delayed startup with "soft start" function, closed-loop control of peak amplitude limiter, soft start, overheating protection, short circuit protection; Perfect protection circuit for short circuit/over current, over voltage, over temperature and limiting.
4. The power supply is made of transformer which is A-class iron core and oxygen-free copper enameled wire to make the power more sufficient and the operating temperature lower.
5. The power filter capacitor uses audio special capacitor, less distortion, lower internal resistance , and the charge-discharge flow is faster and stronger.
6. TFT color screen display: the panel adopts 2.4-inch TFT color Chinese/English LCD screen display, and display content have volume, internal temperature, sensitivity, limiter switch and working mode.
7. Designed with fluid mechanics, reasonable natural and forced air cooling, ultra-quiet operation, able to withstand relatively harsh environment.
8. The installation way adopts the standard 19 "frame width and 2U, 9" case design.
