product introduction

SONIC PRO®soundMASeries amplifier is a high performance, high reliability power amplifier,MAThe series of power amplifiers have been further upgraded from the circuit and appearance on the original basis. The appearance has been applied for a national patent and obtained a patent certificate;MASeries power amplification circuits are developed in advanced and matureABComprehensive optimization and line adjustment have been made based on the class circuit, and top-level power amplifier tubes have been used to further optimize the sound and continue to provide surging driving force; at the same time, the back panel has been added6road220VThe power sequencing power supply socket supports remote control, so that it does not need to match the power sequencer in small and medium-sized sound reinforcement situations; it can accept the linkage control of the audio matrix processor in this brand to realize the remote control of the equipment on and off function; The air duct cooling system and the fully automatic protection system have also been upgraded accordingly, allowing the amplifier to work reliably and stably in various harsh environments, which is more conducive to improving work efficiency and stability; and the latestMAseries power The amplifier has added expensive electronic voltage limiting circuits and current bridge circuits to make power amplification safer; the appearance has been redesigned and is equipped with a display screen with operating temperature, time and voltage displays. The panel is matched with aluminum alloy wire drawing The process is more calm and high-end and is more in line with modern people's aesthetics;MAseries has2×200W-2x1500W8ΩVarious models with rated output power are available for users to choose from, whether paired withSONIC PRO®Both a full-frequency slightly and a double eighteen bass can provide high-quality sound and surging driving power.

product features

The unique LCD work display panel design monitors and displays working temperature, working time, and working voltage, providing reliable data for sound engineers to judge the working status of the equipment. built-in limit Amplifier, which is a protective circuit that can very effectively prevent damage to the speaker. When the power amplifier is clipped and overloaded, a large amount of harmonic energy will be generated, overloading the speaker and damaging the loop.MAThe series is specially equipped with a nonlinear comparator. When the signal is clipped, the power amplifier can immediately adjust the working state of the circuit until the clipping is eliminated.
