Bosch PLE-1P240 Plena Amplifier

Model: PLE-1P240

osch PLE-1P240 overview

Description

The charcoal finish PLE-1P240- Plena Amplifier from Bosch is a high-power plug-and-play power amplifier that delivers 120W to constant voltage or 4 Ω loads. It is built with premium quality and protections and offers basic functionality. The amplifier offers straight 1 V and 70 V line inputs, and 25 and 70 V and 4 Ω outputs. It can extend the power of the PLE- series mixer-amplifier or be combined with the PLE-10M2-US mixer, or work anywhere where more power on an existing 70 V line is needed, or when a line level signal is provided.

Protection

The amplifier is protected against overload and short circuits. A limiter protects the amplifier and loudspeaker against accidental overdriving. A temperature-controlled fan ensures proper cooling without producing acoustic noise at lower output levels.

Power Input and Output

The unit operates both on mains power and on a 24 V battery power supply for emergency backup, with automatic switchover. The amplifier also has a built-in charger to charge the connected battery. The system has 2 balanced inputs that are summed together and a loop-through facility.
This makes it easy to connect multiple amplifiers. The secondary input is a 70 V line input to connect the amplifier to a 25 and 70 V loudspeaker line to provide more power in remote locations. Gain or level control is located on the rear of the unit to avoid accidental setting change. An LED VU meter shows the output level. The amplifier has 25 and 70 V outputs for constant voltage loudspeaker systems, and a low impedance output for 4 Ω loudspeaker loads.
