With a 1U rack 19 - inch size, it's a perfect fit for various installations, thanks to its multi - channel design. Key features include a high - current switching power supply for high - power output with low noise and distortion, short - circuit and thermal protection, a built - in limiter, and easy - to - reach front - mounted gain controls. It also has remote functions like disabling outputs, priority and test triggers, and a failure status indicator. Available in 2 - channel or 4 - channel options with a power output of 2X150W/4X300W on 70/100V lines, it's a switching power, class - D amplifier that stands out.


Using the ART HVA1 amplifier is quite straightforward. First, connect your audio source to the input Euroblock connectors. Make sure to set the 70/100V line option through the dip - switches according to your installation needs. Adjust the gain controls on the front of the amplifier to get the right sound level. You can monitor the performance using the LED indicators. For safety, the amplifier has short - circuit, thermal, and power on/off muting protection, so don't worry about common electrical issues. When it comes to maintenance, keep the amplifier in a well - ventilated area to prevent overheating. Regularly check the connections to make sure they are secure. If you need to disable the amplifier outputs or perform remote tests, refer to the user manual for the specific procedures. Also, pay attention to the remote failure status indicator; if it lights up, there might be an issue that needs to be addressed.
