Built using premium components such as a toroidal transformer, the amplifier is engineered for continuous operation, offering complete short-circuit and no-load protection, along with comprehensive fault signaling for all emergency-relevant functions.

Each channel features two audio input pairs (program + priority), ideal for redundant or priority-based applications. A pilot tone module (FD-20) can optionally be installed per channel for continuous self-monitoring.

Balanced screw terminal inputs and outputs reduce wiring complexity and eliminate ground loop interference. Additional features like power remote control, soft start, LED status indicators, and a switchable 400 Hz input low-pass filter make the BA-2480 DP a robust solution for critical sound systems in airports, transit stations, malls, and government buildings.
