Bosch Plena 120 Watt Power Amplifier

The PLE-1P120 120W Power Amplifier offers a straight 1 V and 100 V line in, and 70 V, 100 V and 8 ohms out. It can extend the power of the PLE- series mixer amplifiers or be combined with the PLE-10M2 mixer. Alternatively, put it to work anywhere where more power on an existing 100 V line is needed or when a line level signal is provided.

• 120 W power amplifier in a compact housing
• 1 V line level balanced input
• 70 V, 100 V and 8 ohm outputs
• 100 V input for slave operation on 100 V speaker line
• Temperature-controlled forced front to back ventilation (directly stackable)
• 24 VDC backup power with built in charger

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 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 100 V line input to connect the amplifier to a 100 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. A meter with LED bar shows the output level.

The amplifier has a 70 V or 100 V output for constant voltage loudspeaker systems, and a low impedance output for 8 ohm loudspeaker loads.
