Description

Bosch LBB 1938/30 Plena 480W Power Amplifier | EN 54-16 Certified

The amplifier is protected against overload and short circuits. A temperature-controlled fan ensures high reliability at high output levels and low acoustic noise at lower output levels. An overheat protection circuit switches off the power stage and activates a LED on the front panel, if the internal temperature reaches a critical limit due to poor ventilation or overload. The unit operates both on mains power and on a 24 V battery power supply for emergency backup, with automatic switchover

For emergency and evacuation use, the following functions are monitored: mains presence, battery presence, pilot-tone presence, amplifier operation. Front panel LEDs indicate the status of supervised functions. The LEDs of pilot-tone supervision and battery status can be switched off for general public address use. Failsafe (normally energized) relays are provided for each supervised function. These relays are always active regardless of the switches on the rear panel.
