Hertz HCP 4D 1160W D-Class 4-Channel Compact Power Amplifier

Description

Improving the Sound of Your Audio System as Well as Your Listening Experience!

4-Channel Power Amplifier — 70 Watts RMS x 4
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-channel 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.

Refined Heatsink with High Convection Capability
The extruded aluminium heatsink provides high-efficiency thermal performance; using the top side of the heatsink to effectively dissipate the heat generated by the electronic components. The internal temperature remains constant at all power levels.

Completed Filter Section
Large array of filters customized for each model, to achieve maximum versatility: Lo-Pass, Hi-Pass, Band-Pass, Full Range, Subsonic, Bass Boost, Phase, and Mono. Filtered pre-amplified outputs along with multiple adjustments are featured on the HCP 1D, offering the user endless connection possibilities with any source.

HCP Electronics
Special balanced input circuitry rejects electromagnetic disturbances present on the Pre-amplified or Speaker level inputs. The power supply stage features a multiple winding transformer and Low-ESR 105C capacitors, selected to ensure high efficiency and current capability.

ART
The Automatic Remote Turn-On/Off function automatically turns the amplifier on and off with the OEM radio; eliminating the need for a remote signal from the source when using the Speaker-In. This function can also be disabled.
