Description：

* Class-D broadcast power amplifier is a high-performance single-channel high-power power amplifier with switching power supply. The structure is compact and reasonable. The intelligent protection circuit adopts advanced class-D digital power amplifier and soft switching power supply to ensure the stability and reliability and protect amplifiers and speakers under extreme conditions.

* It can provide regional power amplification for the system, which is suitable for broadcasting reinforent in a large area, such as medium & large schools, buildings, clubs, venue bars, parks, etc.

Feature：

* The 2U streamlined black alumina brushed panel is perfectly combined with reasonable and compact interior, which is exquisite process.

* The brand-new exclusive third-generation Class-D digital power amplifier, efficient power amplifier circuit, light weight, long system lifespan, high-fidelity sound quality, and perfectly restored sound source quality.

* A good pipe-type heat dissipation structure and built-in automatic temperature control fan cooling system to effectively remove hot air, reduce temperature, and extend normal operation time.

* 1-channel LINE unbalanced TRS/XLR high-quality multi-function input interface, 1-channel LINE balanced XLR cascade output.

* Built-in PFC circuit and soft switching power supply technology. Automatic soft start enables 92% ultra-high system efficiency.

* New power amplifier circuit to ensure zero crossover distortion and lossless signal quality during reinforent.

* Built-in intelligent clipping distortion and over-current protection system can effectively protect the speaker unit.

* It has multiple intelligent detection and protection systems for over temperature, over voltage, under voltage, over current and short circuit.

* 2 output modes: constant impedance 4-16Ω and constant voltage 100V are optional.

* LED indicator for overload.

* Overload and short circuit protection.

* Standard rack mounted installation.
