Where to buy?

The DPA series amplifiers are Class-D power amplifiers designed to meet the requirements for various kinds of applications, ranging from standard stereo home applications to multi-zone distributed speaker systems. They are designed in six different models of Class D power amplifiers, divided in three different architectures to meet the requirements for all kinds of applications. They combine the best of all features in one single series of amplifiers, providing an outstanding sound quality with all the known advantages of Class-D Amplifiers. Such as the excellent efficiency and very low heat dissipation. And due to the complete passively cooled entity only a minimal of maintenance is needed, while ensuring maximum reliability. The small size of a single rack space make them very interesting for fixed rack mount as well as mobile applications. The DPA252 is built as a two channel (Stereo) amplifier capable of delivering a power of 2 x 250 Watt in stereo mode, or 500 Watt in bridged mono mode. It features various specific functions and advanced protection circuitry which protects against DC malfunctioning, short circuit, overheating and overload. The signal input connections are integrated with balanced XLR connectors, and signal link through is possible using the XLR output connectors. The operation mode can be selected between stereo mode, bridge mode and parallel mode. The output connections are both accommodated with both Speakon connectors and Euro-Terminal connection blocks.
