The Bosch LBB1930/20 is a compact yet powerful 120 Watt, power amplifier with 100 volt line constant voltage and 8 ohm low impedance outputs.
2U high 19” chassis for rack mounting or tabletop use.
The LBB 1930/20 is an ideal PAVA amp for emergency and evacuation use, with the following monitored functions: mains presence, battery present, pilot tone presence, amplifier operation.
Operates both on mains power and on a 24 V battery power supply for emergency back up, with automatic switchover.
There are two separate priority controlled 100 V outputs for zones that only need announcements made via the priority input, and for zones that will not receive announcements made via the priority input.
