The SPA550 kit is considered as the "normal" amplifier choice for most HiFi woofers. It produces 2 x 220W
at 8Ω and 2 x 350W at 4Ω. It contains a set of Ground Sound modules
to build a high performance amplifier. The AmpC modules makes the amplifier smooth running at power on and off. The Transformer is
custom-made and has sufficient power for two PA3CC modules. The PSU8DB is the "battery" of the amplifier - it has dual
bridge rectifiers to lower the noise of the power ground and giving better conditions for the transformer. The PA3CC amplifier
modules has very good sonic qualities, which several of our customers has discovered.
