HELVIA ZEUS 404X | Four-Channel Amplifier 4x 600W / 4Ω with Crossover
The HELVIA ZEUS 404X amplifier is ideal for multi-channel low-impedance installations. It is a 4-channel Class H amplifier, offering excellent sound quality and maximum reliability
It supports Stereo, Parallel, and Bridge modes (CH1-2 / CH3-4)
Each channel includes a built-in crossover with a low-pass filter, allowing use with both full-range systems and subwoofers without the need for external processors
The protection system includes signal limiter, on-off muting, DC-offset detection, thermal protection, and current limiting
The cooling system is highly efficient, regulating the speed of two fans while maintaining a low noise level
The quality of copper used in the power transformer, the carefully selected capacitors and power transistors, as well as the precision of the filters, make the HELVIA ZEUS 404X an extremely stable and reliable amplifier, suitable for both permanent installations and live sound applications
