HCP 4 Ch: 4 - 3 - 2 | 760 W

HCP 4 is a four channels car audio amplifier designed to reproduce any musical genres with four separate channels for multiple configurations. Pre-amplified (Pre-In) inputs and high-level (Speaker-In) inputs allow for connection with any head units. Built to work both in mono, as part of a three-channel system with sub and front, and in stereo for a powerful two-channel system, HCP 4 is a unique model in terms of versatility!

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 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.

HCP 4
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 4
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.

HCP 4
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.
