The ART HVA4 – 4 Channel Amplifier 70V/100V is a pro-grade switching power amplifier with a built-in limiter and front-mounted gain controls. Ideal for installation applications the HVA4 provides high-power output with low noise and distortion with Class-D amplification for optimal sound reproduction. You can switch the output power via the dip switches located on the rear of the amplifier. The four-channel design features gain controls and LED indicators for both channels with a streamlined design for simple and easy operation. The Euroblock I/O connectivity allows you to process input and output connections via Euroblock connectors. Whilst designed with live sound primarily in mind the HVA4 can be used for a range of applications thanks to its intuitive design. The built-in limiter helps to rein in hot signals ensuring optimal clarity even at high volumes. The front panel also features LED indicators for Signal Clip Protect and Power parameters allowing you to monitor the amplifiers status at a glance. The rack-mountable design makes it perfect for live installations complete with a remote failure status indicator and a priority remote test trigger for troubleshooting.
