"Three 600 Watts amplifier modules PA6CC sit on the heat sink of Chassis 1503 box – these use classical designed
Class AB
output stages with 12 pcs. bipolar power transistors."

"The power supply PSU12SA supplies all three amplifier modules
and the crossover with necessary DC voltages.
PSU12Sa has a mains filter keeping 230V mains disturbances away. An important part of the power supply is the soft
start circuitry for the gigantic 1.500VA toroidal core transformer, which can be a real challenge
for all
automatic fuse/circuit breaker devices."

"Optimum optimized: With the digital crossover DCN23 included in kit 1503 of Ground Sound we succeeded
to exceed the reference the project (HOBBYHiFi 5/2006) over it self. The crossover setup can be received free
of costs by Hobby HiFi readers: Email to TechnikalTalk@HobbyHiHi.de"
