Information
The HVA4 power amplifier is a high-efficiency four-channel Class D amplifier designed for 70V and 100V installation systems. The device delivers 270W of power per channel, ensuring stable sound transmission even in large-scale commercial or public address audio systems.
Each channel is equipped with a separate volume control and status indicators that display signal activity, overload and thermal protection. This allows you to conveniently monitor the device’s operation in real time.
The compact 1U rack-mountable housing contains a wide range of features: a built-in limiter, a cooling fan and Euroblock connectors for connecting audio, control and service lines. Thanks to its thoughtful design, the HVA4 combines reliability, performance and ease of integration into any sound system.
