Additional Instruction
When use MP3 player
FM Tuner search radio station by press button for 3 seconds after switch MP3 to FM tuner, the device will search
stations automatically, user is able to switch or change different tuner stations by press
all stations searched and saved, or use the digits on remote to select tuner stations.

When use FM tuner
Make sure the volume control adjust to minimum level after amplifier connected audio inputs and loud-
speakers, it avoid sudden impact current to amplifier, makes power amplifier work in good condition.
Power on the amplifier, the power supply LED lite on. Volume control knobs adjust power output to
loudspeakers.
MEDIA PLAYER
The mixing amplifier PD-120D integrated built-in media player, that includes USB slot, SD card slot and
wireless Bluetooth. Switch different source by MODE button.
Bluetooth receiver is allowed to streaming wireless audio to
the sound system. Simply use smart phone or other device
turn on Bluetooth search and find name “BLUETOOTH” in the
list, and connect it (no password required).

Stereo Mixing Power Amplifier
Make sure the volume control adjust to minimum level after amplifier connected audio inputs and loud-
speakers, it avoid sudden impact current to amplifier, makes power amplifier work in good condition.
Power on the amplifier, the power supply LED and protective LED indicator lite on, and protective indicator
goes dark after few seconds.
Two volume control knobs adjust power output to loudspeakers respectively. Input A and Input B lead
2 separate speaker channel.
The Clip LED indicator may flash if any channel output high volume, the LED indicator illuminate
continuously. It will lead distortion of sound when that happens, the limiter may be activated to keep amplifier
keep normal performance. Turn volume down till Clip indicator vanished, doing that will prevent clipping of the
device and distortion of audio signal output.
Softstart
Loudspeakers get protected from electric impulses, what are generated by amplifier when switching on the
power, the current may cause loudspeaker into faulty.
DC protection
It protect the amplifier against wrong voltage contacts at the speaker terminals.
Overload protection
Protects the amplifier and loudspeaker against excessive loads, excessive input signals, insufficient
resistance at loudspeaker connection.
Thermal protection
In additional to well designed ventilation of amplifier structure, the circuits has protection of transistors
against high temperature.
Turn off the amplifier if the protective LED indicator flashes. Check the connection of amplifier and speakers,
and let the amplifier cool down for a moment. Send the device to qualify maintain service center for repair
if problem still exist after amplifier turn on.
Humming Noise
If you experience humming sound during the use of amplifier, check the cable connection and loudspeakers
first. Switch the “GND/LIFT” selector to “LIFT” side, the noise will be diminished completely.
MIC INPUT
1 universal XLR microphone input is compatible for different mic plug, either in 6.3mm or male XLR connector,
the mono microphone can give public speech or temporary talking to audience.
Dynamic microphone is allowed to connect to amplifier PD-120D directly, the volume is adjustable from front
knob, to obtain proper sound level for mic.
