The Bosch Plena mixer amplifier is a versatile, high-performance unit with four mono microphone inputs and a music input having variedamplification range. It fulfills a wide variety of public address requirements at a surprisingly low cost. The Plena mixer amplifiers come in arange of maximum output power. This power is directly available on 70 V and 100 V constant voltage connections and on a low impedanceconnection for an 8 or 4 ohm load. For more output power than the built-in power stage can deliver, additional Plena power amplifiers can beconnected to the balanced line output in a loop-through arrangement.

The LBD 193x amplifiers are powerful power amplifier in a 2U high 19”case (3U housing for LBD 1938) for rack mounting or tabletop use. TheBosch Plena power amplifier series with its varied amplification range fulfills a wide variety of public address requirements at a surprisinglylow cost. The amplifier is protected against overload and short circuits. The system has two balanced inputs with priority control, each with aloop-through facility. This makes it easy to connect remote systems that require priority control. An additional 100V line input is provided toconnect the amplifier to a 100V loudspeaker line to provide more power to remote locations. The amplifier has 70V and 100V outputs forconstant voltage loudspeaker systems, and a low impedance output for 8 ohm or 4 ohm loudspeaker loads.
