Helvia Zeus 900-AB Professional Class-AB Power Amplifier
ZEUS amplifiers always mean reliability and ruggedness. They were born for fixed installations or live applications of low-impedance professional sound systems, and offer RMS powers ranging from 100W to 1000W @ 8ohm per channel.
The series consists of 2-channel models, three of them in class AB; two in class H. Thus, these are equipment whose technologies are extensively tested and guarantee the highest audio quality.
The difference from similar systems depends on the great attention paid to the quality of the components (toroidal transformers, electrolytic capacitors, transistors and others) and to the efficiency of protections and limiter, all while always considering robustness, durability and safety of both internal circuitry and driven speakers.
