HA1400

1. Class H professional power amplifier, super stable and full of power;
2. Through the integrated design of a single module, the power supply and the amplification circuit are integrated into a board, and with the newly designed equal area, short path, short air range, wave mold open radiator structure, the failure caused by the connection line between the lines is avoided to the greatest extent, the heat dissipation efficiency of the whole machine is improved, the weight of the whole machine is reduced, the volume of the product is reduced, the lower cost is achieved for transportation and installation, and the perfect combination of product economy and reliability is realized.
3. The whole series of products adopts the original imported power tube direct to the radiator design, which can more effectively reduce the temperature of the power tube and improve the stability of the product. XLR input and parallel interface are used.
4. The output adopts NL4 Speakon and binding post two kinds of audio interfaces, which are suitable for all speaker wiring systems. Dual-channel and parallel modes are selectable.
5. ACL clipping protection and indication circuit is used to ensure the maximum dynamic range of the signal, and cooperate with the output short-circuit protection circuit, DC protection, infrasound protection, overheat protection, overtemperature protection, surge protection, input overload protection, etc., to ensure the stability and effect of the product. Three levels of sensitivity are selected, which are designed at 0.75V, 1.0V, and 1.5V to meet different professional applications.
