V2x series two-channel broadcast digital amplifier, reflecting the development of innovation beyond the theme, with profound significance of technological change, the most can reflect the concept of green energy conservation and environmental protection.
The distinctive feature of V2x is not limited to the application of new technologies such as Class D amplifiers and switching power supplies, but eliminates the output transformers commonly used in broadcast amplifiers.
Now, the patented technology from ZL03129831.1 has been a successful breakthrough, improving key technical indicators such as distortion, frequency response and load adjustment rate, and reducing the loss caused by transformers. At the same time, reduce the consumption of copper, iron and other metals, broadcast amplifiercancan can also achieve small, light, thin.
■Two-channel independent 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.
