Bosch LBB1935/20

The Bosch LBB1935/20 is a powerful 240 Watt power amplifier in a 2U high 19” case for rack mounting or tabletop use.

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.

LEDs on the front panel of the LBB1935/20 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.
