This audio power amp meets the strictest requirements regarding quality and solidity. Due to a very special circuit the output stage always sets itself at CLASS A without any unnecessary loss of power, hence the name "EFFICIENT CLASS A". The amp is made up of two completely separated mono amplifiers, resulting in no crosstalk between channels. A major advantage of this amplifier kit is that NOT A SINGLE ADJUSTMENT is required! Provisions are made to switch the two channels in "bridge", allowing the power to be doubled (mono). The amplifier is provided with a short-circuit protection and a thermal protection. Furthermore, the speakers connected to the amplifier are protected against switch-on clicks and against D.C. voltages which might occur on the output. The amplifier comes complete with heat sinks, transformers andhouse. Music power: 2 x 300W at 4 ohms / 2 x 200W at 8 ohms - RMS power: 2 x 155W at 4 ohms / 2 x 100W at 8 ohms (1% THD) - Bridged power: 600 W music power - 300WRMS / 8 ohms - Harmonic distortion: 0.008% (1W/1kHz) / 0.005% (90W/1kHz/8ohm) - Damping factor: >600 (at PCB output) - Input impedance : 47 Kohms - Input sensitivity : 1Vrms - Frequency response : 3 - 120kHz (+/-3dB) - Power bandwidth : 5 - 50kHz (+/-1dB) - Signal-to-noise ratio : 112db A-weighted against full power - Speaker switch-on delay : +/-2 sec. - D.C. voltage protection of the output : from +1V and -1V - Short-circuit protection and thermal protection (+/-95?C) - Efficiency : >70% - Power consumption : 450W max. - Dimensions W x H x D : 425 x 90 x 355mm
