Housed in the same chassis, but following up on the model 302 this is the next high end approach to using ICE-power. As far as I can find out these models use the same electronics as thhe previous 302. Perhaps it was only a nomenclature change. Inside is a huge power transformer but it isn't used in the regular way, instead it is used for filtering. After that follows the power factor correction, followed by a switched power supply. This amp can be fitted with one, two or four ICE-power channels according to taste. With 2 channels installed, 300 watts are available, dropping to 250 watts when 4 channels are installed. This is because the modules are fed from the same 1200 watt power supply. The 301 is mono, 312 is stereo and 304 is 4-channel.

Model 302 inside - the big transformer isn't used in the normal fashion but as an extra filterstage before the swithcing power supply
