The Penton BPA-2480 is a 2RU 19" rack-mountable, 2-channel amplifier, transformer isolated for 100 V, 50 V and 8 Ohm distributed loudspeaker systems. There are three models in the coverage of BPA:.
The BPA-2480 amplifier has a 230 VAC mains supply input and a 48 VDC battery back-up input which allows it to be used in combination with a battery backup system for maximum availability and reliability in an emergency evacuation system. BPA amplifiers have short-to-ground, short-circuit detection and line-impedance surveillance up to 5% deviation using the DIVA8G2 or IDA8 systems for loudspeaker-line surveillance. They support both single-spure and redundant loop cabling (A/B) and have a switchover facility that automatically reroutes power to a backup amplifier (if present) via the SONAES charger in the event of failure. BPA amplifiers have a rear-panel selector switch for amplifier monitoring according to EN 54-16
