V4x series four-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 V4x 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.
The first letter "V" of the V4x series model is represented as the broadcast amplifier series;
The second digit of the model "4" is represented as a four-channel;
The third letter "x" of the model is three or four Arabic digits, indicating the rated output power.
