- 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. It
- features dotato a status monitor communicating with the user through a LEDs system.
- The double-extrusion heat sink and the Hertz logo, which is back lit and can be rotated, allow especially sophisticated installations.
