The BA-2480 DP is a fully monitored professional 2-channel 48,3 cm ( 19 inch ) power amplifier, ideally suited for public address and emergency systems using 100V, 50V, or 25V line technology. Delivering 2x 480 W RMS (or 2x 720 W program power), this amplifier is designed for continuous operation and excels in safety-critical installations such as voice evacuation systems and large-scale sound distribution networks.

Built with premium components, including a toroidal transformer, the BA-2480 DP ensures reliable operation and long service life. It features fault monitoring for all emergency-relevant functions and is fully short-circuit and no-load safe. Soft-start circuitry and power-on noise suppression make it ideal for sensitive environments.

Each channel includes two electronically balanced program inputs and two additional priority inputs for emergency announcements. All inputs and outputs are provided via screw terminals, eliminating the need for XLR connectors and simplifying wiring. Multicolored LED indicators on the front panel provide real-time status information.
