The physical size of the Helix M-series amplifiers is very small, although the feature list and power are large. This is possible thanks to advanced Class D technology.
A smart speaker-level input works even in new cars thanks to the ADEP circuit. And this amplifier won't turn off at every traffic light either, thanks to Start&Stop compatibility. The distribution filters have a wide enough range of adjustment to make distributions from subwoofer to tweeter and in between.
Despite their small size, Helix's M-Series offer plenty of power and, above all, the excellent sound quality Helix has been known for as a manufacturer for decades.
