Description
The Bosch PLE-1P240-EU and PLE-1P120-EU are two high power plug-and-play cost effective power amplifiers that deliver 240 and 120 Watts to constant voltage or 8 ohm loads. Built with premium quality and protections, they offer basic functionality at a budget price. The Bosch PLE-1P240-EU amplifiers offer straight 1V and 100V line in, and 70V, 100V and 8 ohms out. They can extend the power of the PLE- series mixer amplifiers or be combined with the PLE-10M2-EU mixer, or work anywhere where more power on an existing 100 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 24V battery power supply for emergency back up, with automatic switchover. The amplifier also has a built‑in charger to charge the connected battery. The system has a balanced input and loop‑through facility. This makes it easy to connect multiple amplifiers. The secondary input is a 100V line input to connect the amplifier to a 100V 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. A meter with LED bar shows the output level. The amplifier has a 70V or 100V output for constant voltage loudspeaker systems, and a low impedance output for 8 ohm loudspeaker loads.
