FEATURE
INTRODUCTION
The PLA2FX power amplifier is designed for
providing powerful output to speakers used in
stereo sound system, 2.1 home theaters,
gaming media system and other listening
applications. With Class-D output circuitry, a
switching mode power supply offers high
efficiency and excellent performance.
PLA2FX can be used as a two channels, 2.1
channels, bridged as a 1 channel amplifier.
With LPF switch, it also could be used as a
subwoofer amplifier. Built-in DSP (Digital
Signal processing) microprocessor
to adjust the audio input signal digitally for
any kind of speakers and music. Therefore,
with the compact size and extremely flexible
of amplifier, PLA2FX can be used in many
different applications.
* Selection for Power-Up mode
(ON/AUTO/TRIGGER)
* TRIGGER IN/OUT could be external remote
ON/OFF
* Natural cooling without Fan.
* Activated standby mode active after 15
minutes of no signal detected.
* Red LED (Front Panel) to indicated Standby
mode is active.
* Protection: Short circuit, Overheating,
Overvoltage, Overcurrent.

1. TRIGGER IN : Apply 12VDC to this connector
to active the unit.
2. ETHERNET: Connect to the local router via
this RJ-45 port.
3. PRE OUT: A buffered Line out is available to
extend the audio signal to another PLA2FX
or other amplifier as needed.
4. LINE IN: RCA Analogue Line input.
5. SPEAKER OUTPUT: Connect the
loudspeakers here. Please connect the
speaker cables correctly between the
positive (+) terminal of the unit and positive
terminal of the speaker, and also between
the negative (-) terminal of the unit and the
negative terminal of the speaker.

6. AC INPUT: Please plug the AC power cord
properly before turn on the amplifier.
7. TRIGGER OUT: Provide 12VDC to trigger
another device.
8. LOW PASS FILTER (LPF): Set to OFF
position, the amplifier works as a stereo
amplifier. Set to ON position, the amplifier
works as a subwoofer amplifier.
9. SPEAKER SET: There are three positions,
Bridge(Mono), 8Ω(Stereo), 4Ω(Stereo). The
defaultSetting is 8Ω. Please set to the
properly impedance corresponding to the
connected speakers.
