HCP 1MDK mono marine amplifier features latest generation D-Class 2Ω stable output stage reaching the impressive RMS power of 740 W x 1 (4 Ω). Engineered and tested for the real environment of application (UV, salt-fog, vibrations, high/low temperature, thermal shock, dust), HCP 1MDK features a compact design built from extruded aluminium heatsink with top side ensuring effective heat transfer. The special balanced input circuitry reject electro-magnetic disturbances and the Hi-Level and lo-level inputs are compatible with any source. The Adjustable Bass Boost (50 Hz) with continuity between 0 dB and 6 dB adds more punch to subwoofer and SUBSONIC filter (24 dB – 25 Hz), removes very low subsonic frequencies from music signal to prevent damage to the subwoofer. The continuously adjustable PHASE control (0 to 180°) optimizes alignment of woofer bass frequencies with sub ones. The Optional Remote Volume Control (HRC) provides the ability to adjust subwoofer volume level from the dashboard.
