audio Amplifier, professional audio power amplifier and public broadcasting system power amplifier manufacturer

Audio power amplifier, referred to as power amplifier, is a device that amplifies the weak electric signals of the future self-confident signal source to drive the loudspeaker to produce sound.

Power amplifier topology of public broadcasting PA system

Professional power  amplifier XBPA-C0500 /C0700/C0900/C1200.

Product features

u  Professional design solid surface durable, adopt industrial molding steel panel;Adopt the front and rear ventilation mode to ensure the heat dissipation of the power amplifier, and solve the problem of overheat protection.

u  Start up soft start, double relay delay start up, prevent to absorb large current to the power grid when starting up, and interfere with other electrical equipment.

u  The audio special ring transformer is used to provide the power supply with more than the rated power, so the amplifier has a very good load capacity and strong dynamic sense.

u  With three big pressure power bridge pile, deserve to go up air using the high density of aluminum radiator, easily guarantee power amplifier in dynamic, loud level of exquisite and reduction, improve the load capacity and stability of the product.

u  IC adopts low noise, high quality pure imported components, high precision resistance. Capacitor ensures the fine performance of the circuit and the zero drift.

u  Intelligent control forced cooling design, fan noise is small, heat dissipation efficiency higher characteristics.

u  Built-in intelligent pressure limit system, control power module and loudspeaker system work within safe range.

u  Built-in 30Hz/50Hz high-pass filter.

u  Multiple modes: stereo, bridge, parallel.

u  Abundant reserve power, can take 2R low resistance output, high fidelity sound quality perfect restore the quality of audio source, can let the actor play the best.

u  High quality transformer and low resistance large capacity electrolytic filter to ensure the high dynamic work.

u  High efficiency power amplifier circuit, perfect reliable safety protection measures and working status indication (short circuit, overload, dc and overheat protection, transformer overheat protection), let users feel safe to use.
