Description
The Boxlight FrontRow Campus-Wide 4x400W Amplifier is a rackmount 70/100V amplifier designed for distributed public announcement and campus-wide audio systems. Built for hallways, cafeterias, outdoor areas, and other shared spaces, it delivers 400 watts per channel across four channels to support low-impedance constant-voltage speaker systems.
Engineered to work with FrontRow Conductor systems, this Class-D amplifier allows levels and system adjustments to be managed through software for easier control and monitoring. With IEC 60849 compliance, lightweight 1U rackmount construction, and high-quality digital conversion, it provides reliable performance for education, commercial, and facility-wide audio applications.
