The Hertz HCP 4D is a D Class car audio amplifier, able to offer up to 1160W (RMS); it is the ideal choice for those who want high power levels in complex systems. Extremely versatile, complete in its functions, provided with Speaker-In and RCA-In inputs to work with any head units, it has been designed to work also in mono (selectable mode), for a three-channel system with sub and front, or a powerful two-channels system.
All the Hertz Compact Power amplifiers are assembled with high-quality components and feature a complete and by-passable crossover system. The dissipation system is optimized with the heat being transferred to the heat sink and then dissipated through the sides of the amplifier.
Features
- Compact design built from extruded aluminum heatsink with the top side ensuring effective transfer of the heat.
- Special balanced high-noise rejection input circuitry on the Pre-In or Speaker-In inputs.
- Speaker-In (for OEM head units) and RCA-In (for Aftermarket head units) inputs.
- Selectable ART, Automatic Remote Turn-On/Off function, automatically turns on and off the amplifier when the OEM radio turns on and off (can be enabled/disabled, with only Speaker-In inputs).
- Power supply featuring multiple winding transformer, Low-ESR 105°C capacitors, D-Class 2 Ω stable output stage.
- Pre-outs, also available when using Speaker-In level inputs.
- Mono operation mode (selectable) to create a sub + front three-channel system or a powerful two-channel system.
- Bass Boost (50 Hz) adjustable to 12 dB, to increase the subwoofer punch.
- Lo-Pass and Hi-Pass 12 dB adjustable (50 Hz to 3200 Hz) filters, providing the ability to build a front + rear system, a multichannel woofer + tweeter system or a powerful sub + front system.
- Selectable full range power outputs
