The 4CH 750W Dante DSP Amplifier integrates a 3.97-inch color TFT touch screen module and an audio processing unit. It has four analog audio balanced signal inputs, and is processed through a series of software-based digital technologies and finally converted into four balanced outputs. The amplifier is equipped with proprietary control software that supports dual interface operations: a Windows computer version and a version that runs directly on the amplifier touch screen. Users can synchronize the two interfaces through the touch screen, Dante network protocol or USB connection.
