Hifonics ZXR750/1E - Class D digital mono amplifier

HiFonics ZXR750/1E

The ZEUS E-Class expands the proven ZXR series with very modern, highly efficient Class D models. These "expansion" amplifiers impress with enormous power in particularly compact heat sinks. Even at their debut in Car & Hifi (issue 1/2025), they impressed the editors across the board – so much so that the series was awarded the prestigious title of PRODUCT OF THE YEAR 2025.

Anyone familiar with HiFonics amplifiers knows that they are always equipped with the latest technology and sophisticated features. However, in high-quality systems with multiple components, certain functions such as high-level inputs are often unnecessary. This gave rise to the idea of developing powerful monoblocks with a stable impedance down to 1 ohm, which deliberately forgo high-level inputs in favor of greater performance and efficiency.

HiFonics now offers three such ZXR/E models with bass level remote controls and outputs of 750, 1000, and 1500 watts RMS, which can adequately drive even large subwoofers. Equipped with the latest Infineon chipsets, they achieve extremely high efficiencies of up to 92%. They thus consume less power and protect the vehicle's electrical system. The ideal combination of a monoblock with the 8-channel DSP amplifier ZXR800/8DSP from the same design line, which features a 10-channel DSP with Bluetooth control, is ideal. Connected via RCA/Cinch, the ZXR/E monoblock delivers the appropriate bass foundation.
