This test report was made to gain more information about another series of Harmotech amplifier – Harmotech H4, the 4 channels amplifier which can produce the power up to 230 watts per channels. It is an interesting point why Harmotech is different from other amplifiers. Let’s follow us to see the details and review.
Specifications and Overview:
This amplifier was born for car audio competition, so all components and compositions in this amplifier have great specifications such as well-cut titanium color heat sink which have no sharply edges left and right.The circuit board of H4 seems like H2, but H4 has more channels, so the circuit board is still using dual mono system, supplying DC power input separately, each stage using twin power switching and the transformer is covered with metal, protecting electromagnetic wave.
The input system uses high grade op-amp I.C. from Analog Device, another component is also using high grade such as +/- 1% resistors, Electrolytic Audio Grade Capacitors from ELNA and bi-capacitors with Polypropylene capacitors from WIMA, Germany. Finally, this Harmotech H4 is using high grade transistors from SANKEN.
