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 DPA152/252 is built as a two channel (Stereo) amplifier, with various specific features
and advanced protection circuitry which protects against DC malfunctioning, short circuit,
overheating and overload.
The signal input connections are accommodated with balanced XLR connectors and signal
