Art HVA1 70V/100V 2-Channel Class-D Installation Amplifier

70V and 100V Installation Power Amplifier for Commercial Audio Systems

The ART HVA1 is a rack-mountable 2-channel 70V/100V installation amplifier designed to deliver reliable, high-power audio for commercial sound systems. It is built for use in retail spaces, restaurants, hospitality venues, meeting rooms, houses of worship, and distributed audio installations where consistent performance and system protection are critical.

High-Efficiency Class-D Amplifier Design

Using a Class-D amplification topology, the HVA1 provides strong output power while maintaining low noise and low distortion. This design allows the amplifier to run cooler and more efficiently than traditional amplifier designs, making it well suited for continuous operation in fixed installations and equipment racks with limited ventilation.

Power Output for Distributed Speaker Systems

The amplifier delivers up to 135 watts per channel in 70V or 100V operation, with the ability to bridge channels for increased output when required. This power range supports long cable runs and multiple speaker zones, making it suitable for paging systems, background music, and announcement applications across large spaces.

Flexible Euroblock Connectivity for Installers

All audio inputs and outputs are provided on Euroblock connectors, allowing clean, secure wiring during installation. This connection format is widely used in commercial audio environments and simplifies integration with mixers, paging systems, DSPs, and other installation-grade equipment.

Front-Panel Controls and Status Monitoring

Front-mounted gain controls provide easy access for system setup and level adjustment without removing the amplifier from the rack. LED indicators for signal presence, clipping protection, and power status allow technicians to quickly verify system performance and troubleshoot issues at a glance.

Built-In Protection and System Safeguards

The HVA1 includes a comprehensive protection system to safeguard both the amplifier and connected speakers. Short-circuit protection, thermal overload protection, and power on/off muting help prevent damage during fault conditions, startup, or shutdown. An internal limiter further protects against overload and distortion during peak signal conditions.

Compact Rack-Mount Design for Professional Installations

Housed in a 1 RU, 19-inch rack chassis, the amplifier fits easily into standard equipment racks. Its compact footprint, switching power supply, and remote control features such as output disable, priority input handling, and remote fault status make it well suited for centralized system control environments.
