Hertz Digital Power Series 4-Channel Amplifier - HDP4
Hertz Digital Power Series 4-Channel Amplifier - HDP4
HDP 4 is a D-Class four-channel amplifier, perfect to satisfy any need. It is the most compact HDP; nonetheless, like the other models, it can reach very high power levels: in less than 30 cm (12 inches) it can provide up to 1000W on 2 channels at 4 Ohm! It can be used in full range as well as with crossover settable as Lo-Pass/Hi-Pass.
It has been thought to offer the user the maximum possible flexibility, both thanks to Speaker In and RCA inputs and to the controls, with a status monitor communicating to the user through a LEDs system. Using Speaker In inputs, the ART™ ( Automatic Remote Turn On-Off) function is available; the user can also switch it off.
HDP 4 is the perfect choice for those who look for performance and non-bulky sizes. The double-extrusion heat sink and the Hertz logo, which is back lit and can be rotated, allow especially sophisticated installations.
Features:
- Thermally optimized double extruded heatsink, ergonomic and aluminium die-cast end caps
- 4 LEDs monitor the status of the amplifier and communicate with the user
- Special balanced input circuitry to reject electromagnetic disturbances present on the Pre-amplified or Speaker level inputs;
- HDP Input featuring either Speaker In (OEM radio) and RCA In (Aftermarket radio) inputs
- 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)
- Full range Pre-out, also available when using Speaker Level In inputs
- 12 dB/Oct. continuously adjustable (50 to 5k Hz and 80 to 3.3k Hz) active crossover with Lo-Pass/Hi-Pass or Full Range settings
- A/B Input switch eliminates the need for RCA Y-Adapters
- Power supply stage featuring multiple winding transformer, Low-ESR 105°C capacitors, D-Class 2Ohm stable output stage based on solid T220-5pin power Mosfets
