Brand NEW! 4-Channel Amplifier / Max Power 800W / 60W RMS x 4 @ 4 ohms Toroidal Transformer Stable power supply is assured thanks to a large-size toroidal transformer. Its high winding density and low flux leakage improves conversion efficiency of the power. The result is natural and powerful music playback throughout the volume range. Speaker-level Inputs for Easy Installation DR Series amplifiers feature speaker level inputs with Auto Turn-on function. Installation is possible without having to detach the receiver.
