This lightweight, class AB amplifier has been designed to the same high standards of reliability and sound quality that our customers have come to expect of all MC2 audio products.
As with all E Series amplifiers, the E45 will deliver its rated power over the entire audio bandwidth, and a resonant switchmode power supply with a large reservoir gives extremely high peak power without any "bass sag"
Optical limiters keep mains input and output currents within a safe operating area at all times, whilst maintaining transparent sonic performance.
Power Reduction Circuitry (PRC) controls on the rear panel , linked to the limiter thresholds, allow each channel to be independently set so that speakers can be safely connected to each channel.
