The 312 stereo power amplifier is equipped with four modern switching power supplies providing power up to 4,200 VA. The increase in instantaneous power has made the stereo amplifier sound more powerful than its predecessors.
The new innovative amplifier topology extends the frequency band beyond 2 MHz, while reducing distortion and noise to a minimum. Four 600 VA switching power supply modules with a rated switching power of 2100 VA each are directly connected to the power amplifier boards, which ensures minimal contact resistance and the shortest signal path from the power supply to the speaker connection terminal.
