HDP 4 is a Class D amplifier with four channels designed to meet any need. It is the most compact HDP model but, like the others, it can reach very high power levels: less than 30 cm in length can deliver up to 1000W on 2 channels at 4 Ohm! It can be used both in full range mode and with the crossover adjustable as Lo-Pass/Hi-Pass.


Designed to offer the user maximum operational flexibility, both from the point of view of Speaker In and RCA inputs, and from that of the controls with a status monitor that communicates with the user through an LED system. On the Speaker In inputs, the ART™ function is available, Automatic Remote Turn On-Off, which can be disabled by the user.

HDP 4 is ideal for those looking for performance and non-intrusive dimensions.
The heatsink with double extrusion and Hertz logo, backlit and rotatable, allows particularly refined installations.

  • Heatsink made with double extrusion thermally optimized, ergonomic terminals in die-cast aluminum
  • 4 LEDs monitor the amplifier status with pre-alarm function (flashing)
  • Special balanced input circuitry for high rejection of electromagnetic interference, in the Pre-In and Speaker-In inputs
  • HDP Input has Speaker In inputs (for factory head units) and RCA In inputs (for Aftermarket head units)
  • ART, Automatic Remote Turn-On/Off, automatically turns the amplifier on and off when the factory head unit turns on and off (can be enabled/disabled only with Speaker In)
  • Full range Pre-out outputs, also available with Speaker In level inputs
  • Active crossover with 12 dB/Oct. slope continuously adjustable from 50 to 5k Hz and from 80 to 3.3k Hz, settable as Lo-Pass/Hi-Pass or Full Range
  • Dedicated switch for A/B inputs, which eliminates the need for Y adapters for RCAs
  • Power supply with multi-filament wound transformer, LOW-ESR 105°C capacitors, D-Class output stage, stable at 2 Ω (1000W RMS), based on robust T220-5pin power Mosfets.
