u 120 and 240 W power amplifier in a compact

housing

u 1 V line level balanced input

u 70 V, 25 V and 4 ohm outputs

The PLE-1P120-US and PLE-1P240-US are two
high‑power plug-and‑play cost effective power
amplifiers that deliver 120 and 240 Watts to constant
voltage or 4 ohm loads. Built with premium quality and
protections, they offer basic functionality at a budget
price. The amplifiers offer straight 1 V and 70 V line in,
and 25/70 V and 4 ohm outputs. They can extend the
power of the PLE- series mixer‑amplifiers 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.

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 backup, 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

u Temperature-controlled forced front to back

ventilation (directly stackable)

secondary input is a 70 V line input to connect the
amplifier to a 25/70 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 ohm loudspeaker loads.
