Networking Power Amplifier

The DD series is a series of network configured Class D amplifiers, designed for high-end conference, entertainment and
touring. They support Lo-Z and Hi-Z output, built in switch, supporting UDP protocol. They are mainly used for high-end
conference, entertainment and touring with excellent sound quality
