PLE‑1Pxx0‑EU Plena Amplifier
The PLE-1P120-EU and PLE-1P240-EU are two high-power
plug-and-play cost effective power amplifiers that deliver
120 and 240 Watts to constant voltage or 8 ohm loads.
Built with premium quality and protections, they offer
basic functionality at a budget price. The amplifiers offer
straight 1 V and 100 V line in, and 70 V, 100 V 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.
Functions
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
▶ 120 and 240 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
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.
