HELVIA ZEUS 4350CA | Four-Channel Final Amplifier 4x350W 100V/4Ω

The HELVIA ZEUS 4350CA amplifier is designed for the world of small and medium commercial sound systems. Compatible with 70V or 100V line voltages, as well as low-impedance lines from 4 to 16 ohms. It offers Class-D amplifiers with 1, 2, and 4 channels, delivering 120W, 240W, and 350W RMS power.

Each channel is independent and has its own linear transformer, allowing selection between 70/100V or 4-16 ohm low-impedance lines. Each channel features volume control, LED VU-meter and clip indicators, and gain adjustment on the rear panel.

Includes a HPF filter with a cutoff frequency at 400Hz. Inputs and outputs are balanced with XLR connections, and all power outputs feature Phoenix (Europlug) connections.

Each channel has a muting system upon activation, signal limiter, thermal protection, and current limiting. The cooling system includes a fan with speed control based on internal temperature. It is further enhanced by the standard 19” 2U Rack size, which improves heat dissipation.

Quality is based on the careful selection of active and passive components, as well as digital processing to ensure stability, reliability, and high-level sound performance.
