Series DH, 4 Channels

The DH Series represents our company's professional digital power amplifiers featuring exceptional cost - effectiveness. These amplifiers incorporate advanced Class - D power amplifier modules and high - efficiency switching mode power supply (SMPS) modules. They come with a built - in DSP processor, are equipped with FIR filters, and are provided with various debugging ports (including a USB interface). Each input and output channel can be configured with a total of 31 equalization bands. The equalization modes include parametric equalization (PEQ), low - shelf filtering (Lo - Shelf), and high - shelf filtering (Hi - Shelf).Widely used in applications such as bar DJ performances, conference presentations, wedding receptions, stage performances, and other events.

You can choose between a 2-channel or 4-channel model.
