LA-series Professional Power Amplifier System
LA series is a kind of power amplifier with high efficient H series circuit. The character of H series amplified circuit is that it canenhance potency and the peak power. This series product adapts advanced scientific design- H series circuit; Our company have integrated many advantages of various famous brands with our longtime research and development. We launch these new holohedralsymmetry amplifiers which reach the requirements of low cost, high durability, flexibility and high quality, and it has suffered long time living test.
Good square-wave response and super low phase shift, 4 Ohm super load capacity;
The function of soft start with turn-on delay, self-adapting limiter with closed-cycle control and protection of over-heat, direct-current output and short circuit;
The cooling system adapts the appropriative exact temperature sensor from American National Semiconductor Company which canforce cooling by intelligence and efficiency to ensure the power amplifier to work under the normal temperature.
The high-rigidity whole-interconnected chassis adapts 4mm super thick and high-strength alufer panel with standard outline dimension.
The high-speed and wideband output transistor can make the HF output much more transparent and clear.
The super smooth controlled switch can well control the voltage gradient between the high frequency and low frequency.
It can reduce the distortion efficiently, and the output part can work for long time to make the power amplifier durability.
No matter for the high and serious requirements tour-living show or for fixed programmed installation in the closed, dark and wet environment, it can also perform its characters with steady and durability, high applicability and property as well as wide frequency response and low distortion.
High-quality imported resistance welding green oil, high-strength double-sided PCB Each module adapts independent power supply mode.
Electronic protection circuitry (DC, over-heat, short circuit and current limiting)
