Hifonics Zeus ZXS700/4 - 4-channel digital amplifier

ZXS700/4

Classic ZEUS amplifiers were previously analog and had a powerful appearance. The large ZEUS amps are still revered by car audio fans worldwide, but the disadvantage of such powerhouses is the large amount of space they require in the vehicle.

For this reason, HiFonics engineers decided to use advanced digital power when designing the new ZEUS STREET ZXS amplifiers in order to achieve ultra-compact heat sink dimensions. This is primarily achieved thanks to modern Class D technology, which, due to its extremely high efficiency of around 90%, requires significantly less power than analog amplifiers with comparable performance. Another advantage is that the cable cross-sections for the power supply do not have to be as thick.

But small does not mean flimsy: as soon as you unpack it, you realize that you are dealing with genuine ZEUS amps. Despite their petite size, the models feel pleasantly heavy in the hand and convey a solid feeling in the usual HiFonics quality. Recessed aluminum logo badges, carefully milled model numbers, and sophisticated cast aluminum end caps visually convey a unique symbiosis of power and elegance that emanates from these amps.

In addition to adjustable crossovers, all ZXS models naturally feature the latest features such as an automatic power-on function, which is required for connection to modern vehicle electrical systems. The high-level inputs are equipped with advanced EPS to suppress error messages in vehicle diagnostic systems. Low-emission HiFonics IFT digital technology ensures interference-free radio reception.
