The LBB1930(35)/20 Range consist of two power amplifiers in a 2U high 19” cases for rack mounting or tabletop use.
LEDs on the front panel show the status of the amplifier: power, audio output level, and supervised functions. This high- performance unit fulfills a wide range of public address requirements at a surprisingly low cost.
The amplifiers have 70 V and 100 V outputs for constant voltage loudspeaker systems, and a low impedance output for 8 ohm loudspeaker loads.
The system 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. Gain or level control is located on the rear of the unit to avoid accidental setting change. A meter with LED-bar shows the output level.
The LBB 1930/20 has 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.
