4-channel active amplifier with digital crossover
I got an assignment from LautsprecherShop.de to build a 4 channel active amplifier.
The amplifier features our DCN24, 4 x PA3CC, PSU12SA and TR550 build into a Modu box
(Pesante dissipante 03/400B 3U 10mm) with custom made front and back panel

First impression of how the amplifier will look when it is finished

One of the four PA3CC amplifier modules mounted on one of the Modu chassis heat sinks

Wiring up the beast - it looks a bit chaotic, but everything is under control

All nicely wired up and ready for testing

First sound test on a pair of inexpensive boxes - just in case... BUT of course it works !!!

XLR - SpeakOn - USB - IEC connectors on the back

Power is "ON" and music is flowing from the speakers !
