The Booster amplifiers are powerful power amplifier in a 2U high 19”case (3U housing for LBD 1938) for rack mounting or tabletop use. The Bosch booster amplifier series with its varied amplification range fulfills a wide variety of public address requirements at a surprisingly low cost. The amplifier is protected against overload and short circuits. 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 100V line input is provided to connect the amplifier to a 100V loudspeaker line to provide more power to remote locations. The amplifier has 70V and 100V outputs for constant voltage loudspeaker systems, and a lowimpedance output for 8 ohm or 4 ohm loudspeaker loads.
