HERTZ HCP 4D D-CLASS FOUR CHANNEL AMPLIFIER

$419.99 USD $459.00 USD
HCP 4D

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.

Technologies

  • REFINED HEATSINK WITH HIGH CONVECTION CAPABILITY

    The extruded aluminum 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 electro-magnetic disturbances present on the Pre-amplified or Speaker level inputs. Power supply stage features a multiple winding transformer and Low-ESR 105°C capacitors, selected to ensure high efficiency and current capability.

  • ART

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