M2xSeries of two-channel professional digital amplifier, set ten years of core technology research and development results, advanced design concepts, uncompromised selection of components, strict production procedures, perfect detection means, created a lightweight body, heavyweight output power digital amplifier, perfect performance to meet your desire for sound.
■TwoChannelIndependent power module structure
Each channel power module is composed of two parts, the switching power supply and the Class D amplifier, each module of the switching power supply only to the D-type amplifier of this channel, each module does not affect each other. This design is inspired by the aviation industry, i.e. the more engines the aircraft are configured, the greater the thrust and the higher the safety factor.
■Advanced technology, sophisticated design
Class D amplifiers use a self-developed composite feedback control strategy. Compared with open-loop or semi-closed-loop control, composite feedback control can greatly reduce the influence of power supply fluctuation, switching device and LC filter error and non-idealization, so that the distortion, frequency response, damping coefficient and other key technical indicators have been greatly improved, and the hearing performance is perfect.
Switching power supplies are optimized for the operating characteristics of the audio amplifier, with strong power, responsiveness and little interference with the audio signal.
■Perfect protection and high reliability
In addition to the short circuit, overcurrent, overtemperature, uHF and other multiple protection circuits, but also pay attention to the user-friendly design, convenient operation, while possible misoperation to prevent.
■Small and dynamic
1U height 19" standard rack size, small size, light weight, flow and fixed installation are suitable.
