HDP 1 is a mono D-Class amplifier providing very high power and efficiency, being able to astonish for the excellent musicality. HDP 1 is ideal to drive subwoofers and can work on 2 Ohm and 4 Ohm loads, providing 600W and 1000W power.

HDP 1 features a subsonic and a Lo-Pass filer, both at 24 dB/Oct. Maximum installation versatility: just like the whole HDP line, the mono is equipped with the HDP IN system which, through the Speaker In and RCA inputs, provides the ability to interface with any OEM and aftermarket source. Using Speaker In inputs, the ART™ ( Automatic Remote Turn On-Off) function is available; the user can also switch it off.
