Helix A4 Black 4-channel high-end amplifier extremely stable under load, thanks to the use of finely selected MOSFETs and the control of all parameters by the integrated processor.

The use of Class A in driver circuits, the tolerance of passive components to 1% minimize distortion and allow perfect sound quality. The A4 Black chassis, extremely flat, shows through the transparent cover the extraordinary circuit cleanliness and the level of components used, all selected in Germany. Black finish.
