The Helvia Zeus 4240CA installation power amplifier has four independent channels, each with a line transformer and a choice of operation at 70/100 V constant-voltage line or low impedance of 4–16 Ω. Each channel features a volume control, a rear-panel gain control, and LED VU meter and clip indicators. The HPF has a cutoff frequency of 400 Hz.
The balanced inputs and outputs connect via XLR, while the power outputs use Phoenix (Europlug) connectors. Each channel features power-on muting, a signal limiter, thermal protection, and current limiting. Cooling is provided by a fan whose speed is controlled according to the internal temperature.
