Hifonics ZXR900/4 - 4-channel digital amplifier

ZXR900/4

It's not just HiFonics fans who know that anyone looking for a particularly good and powerful car hi-fi amplifier is guaranteed to find what they're looking for in the ZEUS models. This formula has been around for a good 30 years, since the legendary ZEUS Series 7 laid the foundation in the early 90s for what ZEUS amplifiers are known for today: maximum power and performance as well as the finest sound—in short, the best that Class A/B technology has to offer.

Connoisseurs know that Class A/B power amplifiers are great, but anything but compact. For this reason, HiFonics engineers have completely redesigned the ZEUS POWER ZXR series as Class D power amplifiers. The result is beautiful powerhouses with very slim dimensions – all in the familiar and popular ZEUS look. No matter where you look, the ZXR amps are superbly crafted. With an outstanding efficiency of over 90%, they don't even need much power to reach their full potential. The ZXR series' sophisticated features also include a wired bass remote, so that levels can be conveniently adjusted from the driver's seat.

Connectivity to modern vehicles is more important than ever these days. Equipped with the latest EPS high-level input, the speaker signal can be easily tapped from the car radio without causing error messages in the vehicle. All amplifiers are cleverly designed to ensure that the EMC parameters are correct, which is reflected in excellent emission values so as not to interfere with radio reception.
