HDP 5 is a D-Class five-channel amplifier suitable for complex installations, able to offer up to 950W total. The built-in crossovers are settable as Full Range and Hi-Pass at 12dB/Oct. or Hi-Pass + Band-Pass and Lo-Pass at 24dB/Oct. The extremely flexible crossover section allows the use of HDP 5 in multiple installations with excellent acoustic results.

Maximum versatility also in connections: HDP 5 features the HDP IN system which, through the Speaker In and RCA inputs, provides the ability to interface with any OEM and aftermarket source. The power stage features a double power supply to ensure energy flows steadily.

The double-extrusion heat sink and the Hertz logo, which is back lit and can be rotated, allow especially sophisticated installations.

1. Thermally optimized double extruded heatsink, ergonomic and aluminium die-cast end caps
2. 4 LEDs monitor the status of the amplifier and communicate with the user
3. Special balanced input circuitry to reject electromagnetic disturbances present on the Pre-amplified or Speaker level inputs;
4. HDP Input featuring either Speaker In (OEM radio) or RCA In (Aftermarket radio) inputs
5. ART™, Automatic Remote Turn-On/Off function, automatically turns on and off the amplifier when the OEM radio turns on and off (available on Speaker In only)
6. Double separate power supply stages for A & B channels, C channel based on multi-winding toroidal transformers plus Low ESR 105°C resistant electrolytic capacitors, D-Class 2 Ω stable output stage based on solid T220-5pin power Mosfets; with compact “install-friendly” connector
