Apart Revamp 2250

REVAMP2250 is a professional 2-channel digital power amplifier with 2 x 350 watts output power @ 4 ohms, but is also bridgeable (1 x 700 watts @ 8 ohms). The unit incorporates a high efficient SMPS power supply and outputs with efficient Class D output topology.
The digital signal processor inside operates with one simple push button at the back of the unit to select an operating mode (6 presets). An example of a preset is the combination CH1 subwoofer and CH2 trafo load. In this example you have a low-pass filter for increased stability when using 100 volt transformers on the output, allowing you to use 100 volt speakers as top speakers combined with a standard low impedance subwoofer.
