MA Series Power Amplifier

Basic Info


Model No.: MA350\MA500\MA650\MA800


Product Description

MA series power amplifier, the integration of the engineers in the audio power amplifier applications, the most advanced technology, a single mode block integration, power tube, direct attached to the radiator and other design tools, power supply of high quality ring transformer, are the perfect response to the MA Series in the market lay a solid foundation.

Feature


Unique Power+ Technology, and other products in the same conditions, with the largest and most real clearance optimization for loudspeaker system;

High quality imported a piece of transformer, the import of large electrolytic capacitors;

Through the integration of a single modular design, the power supply and amplifier circuit integration into a piece of board, and with the new design of the area, short path, the short air path and the wave type heat radiator structure can avoid the faults caused by the connecting line between lines, and the dispersion of the whole machine is improved.

Thermal efficiency, reduce the weight of the whole machine, reduce the volume of the product, to transport and installation to achieve a lower operating cost of the product, to achieve product the perfect combination of economy and reliability.

Using the XLR input and parallel interface.

Output using the Speakon NL4 and the terminal two kinds of audio interface. Dual channel and parallel mode can be selected.

Two sensitivity modes of 1.2V and 0.775V can be selected.

The ACL clipping protection and indication circuit are used to ensure the maximum dynamic range of the signal, and cooperate with the short circuit protection circuit and DC protection, over temperature protection, infrasonic protection, and ensure the stability of products and effects.

From the front to the rear of the wind cooling system.

Application


High power density large and medium bar installation applications; conference / cinema installation applications.
