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.
Enhanced GND
Offers a copper plate for the ground. Its low resistance value reduces loss of voltage to deliver clear sound with less distortion.
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 head unit.
