DYNACORD DPA 8225 is a two-channel amplifier for the PROMATRIX 8000 system. The 19-inch device can be operated both via mains power or via a DC supply. The output voltage is galvanically separated and permanently monitored for earth contact. An energy-saving mode and temperature-controlled fan save power and reduce noise. It is controlled/ monitored via CAN bus. The DPA 8225 is equipped with an additional audio input for background music or for usage as emergency input. A choice of end-of-line surveillance as well as individually configurable impedance measurements provide comfortable monitoring of all connected loudspeaker lines. DPA 8225 also includes the necessary electronics for automatic spare amp switching and for connecting multiple loudspeaker circuits to a single amplifier channel. |
