A fully active surround sound system
- all based upon the active Ground Sound solution !
The
active Ground Sound solution is an intergrated and optimized solution
for activating a loudspaeker system. The solution is comprised of a digital
crossover module DCN23 or DCN24, two or more amplifier modules, toroidal
transformer and a power supply module with soft start, amplifier mute control,
regulated voltages for the digital crossover module and capacitor bank for the
power amplifier modules.

Above you can see the wast number of electronic boxes in Dr. Madritsch's system
- notice the surround processor Lexicon MC12 with room-correction among the devices
The planning phase for the active amplifiers
The active 7.1 surround sound system will be employing both 3-way and 4-way active amplifiers.
Dr. Madritsch has invested in several DCN23, DCN24, PA1CC, PA3CC, PSU4SA, PSU12SA, TR300 and TR600
for realization of his dream system. Further more he has invested in several drivers from Mundorf
- the top model Air Motion Transformer AMT2510C. The bass and midrange drivers are both from
Accuton Thiel - the superb ceramic cone drivers chosen are C173-06-096 and C220-6-222

An very expensive line up of Thiel / Accuton ceramic drivers.
The assistant has been at it - programming the proto type.

Rear speaker front
Right rear speakers with the current Dynaudio Focus sub - will be replaced at some point.
The replacement will be yet an own made construction employing Thiel 280 sandwich drivers

This is the way a real High End surround can be made !
