Hertz Venezia V4C, 4-rių kanalų Marine garso stiprintuvas

INFORMACIJA

Hertz Venezia V4C - kompaktiškas ir galingas 4 kanalų Marine stiprintuvas, sukurtas aukštos kokybės garsui laivuose, kateriuose ir kitose sudėtingose aplinkose. Moderni Hertz Advanced Class-D technologija užtikrina didelį efektyvumą, mažą kaitimą ir švarų garsą net esant dideliam garsumo lygiui. Stiprintuvas turi 4 × 110 W galią prie 4 Ω arba 2 × 380 W tilteliniu režimu, todėl puikiai tinka tiek garsiakalbiams, tiek žemų dažnių garsiakalbiams. Hi-Res Audio sertifikatas leidžia atkurti itin detalų garsą iki 40 kHz dažnio. Integruota apsaugos sistema nuo perkaitimo, perkrovos ir trumpo jungimo padidina saugumą bei ilgaamžiškumą. Kompaktiškas aliuminio korpusas su pasyviu aušinimu leidžia lengvai montuoti net ribotoje erdvėje.

APRAŠYMAS

Venezia V4C compact marine amplifier features an optimized power/size ratio boosting 110 W x 4 (4Ω) and 380 W x 2 (4Ω)! Hertz Advanced Class D technology maximizes efficiency and power while minimizing heat and electromagnetic radiation - enhancing sound quality that reaches new highs with Hi-Res certification! High-powered channels with bridging capability deliver the output levels needed in the marine environment. Venezia V4C is engineered and tested for marine applications (UV, salt-fog, vibrations, high/low temperature, thermal shock) and has obtained the IPX2 certification. The Safe-Lock Input, Output, and Power connections streamline installation and enhance durability in the field. The fanless convection cooling system is integrated into the cast heat-sink chassis. The balanced fully-differential input circuitry rejects electromagnetic noise and interference. The powerful and flexible preamp filter options are far beyond most mobile amplifier capabilities. Last but not least, Venezia V4C is fully protected by short-circuit, overload, and thermal protections - with auto-resetting.

VENEZIA V4C
ADC
Hertz Advanced Class D architecture maximizes efficiency and power while minimizing heat and electromagnetic radiation – without penalizing sound quality! High-powered channels with bridging capability deliver the output levels needed in the marine environment.

Hi-Res
Hi-Res certified performance, with an extended audio band up to 40 kHz.

CORROSION RESISTANT
Electronics components corrosion caused by exposure in wet environments is totally neutralized by the use of dedicated marinegrade (epoxy coated) PCB boards.

SALT FOG TESTED
To satisfy the standards required by ASTM-B117, Hertz Marine products are tested with massive salt fog spray to ensure a complete resistance to corrosion, typical of this atmospheric agent.

WATER JET RESISTANT
This Hertz Marine amplifier is IPX2 certified when installed vertically with connections facing downward.
