The ART HVA Series 1 and 4 are outstanding class-D installation amplifiers. Ideal for 70/100V line installations (selectable via dip-switches), these amplifiers bring great flexibility. Each channel comes with its own gain control and useful LED indicators (signal, clip, and protection). Input and output connections use Euroblock connectors. With a 1U rack 19-inch size, they fit well in various installations, thanks to their multichannel design. Key features include a high-current switching power supply for high power output with low noise and distortion, short circuit, thermal and power on/off muting protection, a built-in limiter, Euroblock input and output, front-mounted gain controls for easy access, signal, clip protect, and power LED indicators to monitor performance, the ability to disable amplifier outputs remotely, priority and remote test trigger, a remote failure status indicator, 2-channel or 4-channel options, 70/100V line operation, a power output of 2X150W/4X300W, and a switching power class-D amplifier design.
Using this ART HVA4 amplifier is easy. First, connect your devices to the input using the Euroblock connectors. Then, use the front-mounted gain controls to adjust the sound level as you like. You can monitor the performance through the LED indicators. Make sure to place it in a well - ventilated area to avoid overheating. Don't forget to check the dip - switches to select the appropriate 70/100V line installation. When it comes to maintenance, keep it clean and dust - free. If you encounter any issues, you can check the remote failure status indicator for clues. If you want to disable the amplifier outputs, you can do it remotely. And remember, don't overload the amplifier to ensure long - term use.
