HELVIA ZEUS 4350CA | Four-Channel Power Amplifier 4x350W 100V / 4Ω
The HELVIA ZEUS 4350CA amplifier is designed for small to medium-sized commercial audio systems, supporting both constant voltage lines (70V / 100V) and low-impedance connections ranging from 4 to 16 ohms. It features Class-D amplifiers with 1, 2, or 4 channels, delivering 120W, 240W, or 350W RMS output power
Each channel operates independently and includes its own line transformer, allowing selection between 70/100V and 4–16Ω low impedance, ensuring maximum flexibility for the specific needs of each zone
In addition to volume control, each channel offers LED VU-meter and clip indicators, as well as gain adjustment on the rear panel
A high-pass filter (HPF) is included, with a cutoff frequency set at 400Hz
Inputs and outputs are balanced XLR connections, while all power outputs use Phoenix (Europlug) terminals
Each channel is equipped with power-on muting, signal limiter, thermal protection, and current limiting
The cooling system includes a temperature-controlled fan, and the standard 19” 2U rack-mount chassis improves heat dissipation
The quality is ensured not only by the careful selection of active and passive components, but also by the materials used in the line transformers and the digital processing, which provides stability, reliability, and high-level audio performance
