HVA4
4-Channel 270 W Power Amplifier
The HVA4 is a four-channel Class D amplifier for 70V and 100V installations that delivers 270 watts per channel.
Each channel has an independent volume control and status LEDs to indicate signal activity, clipping, and thermal protection.
With a robust feature set in a 1U rackmount enclosure, the HVA4 offers a built-in limiter, an internal fan, and Euroblock connectors for audio, status, and control signals.
