The Bosch Plena LBB1935/20 is a powerful 240 Watt power amplifier in a 2U high 19” chassis for rack mounting or tabletop use. The LBB 1935/20 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 24V 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. LEDs on the front panel of the LBB1935/20 show the status of the amplifier: power, audio output level, and supervised functions. This amp has two balanced inputs with priority control, each with a loop-through facility. This makes it easy to connect remote systems that require priority control. An additional 100 V line input is provided to connect the amplifier to a 100 V loudspeaker line to provide more power to remote locations. This high performance, versatile power amplifier fulfills a wide range of public address requirements at a surprisingly low cost.
