USER'S MANUAL

The symbol is used to indicate that some hazardous live terminals are involved within this apparatus, even
under the normal operating conditions, which may be sufficient to constitute the risk of electric shock or
The symbol is used in the service documentation to indicate that specific component shall be replaced
only by the component specified in that documentation for safety reasons.

ON: Denotes the apparatus is turned on
OFF: Denotes the apparatus is turned off.
WARNING: Describes precautions that should be observed to prevent the danger of injury or death to the operator.
CAUTION: Describes precautions that should be observed to prevent danger of the apparatus.
IMPORTANT SAFETY INSTRUCTIONS
The apparatus should be protected from moisture and
rain, can not used near water, for example: near bath-
tub, kitchen sink or a swimming pool, etc.
The apparatus should be located away from the heat
source such as radiators, stoves or other appliances
that produce heat.
Do not block areas of ventilation opening. Failure to
do could result in fire. Always install accordance with
the manufacturer's instructions.
Objects do not fall into and liquids are not spilled into
the inside of the apparatus for safety.
Protect the power cord from being walked on or pinched
particularly at plugs, convenience receptacles, and the
point where they exit from the apparatus.
Do not defeat the safety purpose of the polarized or
grounding-type plug. A polarized plug has two blades
with one wider than the other. A grounding type plug
has two blades and a third grounding prong. The wide
blade or the third prong is provided for your safety.
If the provided plug does not fit into your outlet, refer to
electrician for replacement.

IMPORTANT SAFETY SYMBOLS
·Power Supply
The apparatus should be connected to the power supply
only of the type as marked on the apparatus or described
in the manual. Failure to do could result in damage to the
product and possibly the user.
Unplug this apparatus during lightning storms or when
unused for long periods of time.
·Fuse
To prevent the risk of fire and damaging the unit, please
use only of the recommended fuse type as described in
the manual. Before replacing the fuse, make sure the unit
turned off and disconnected from the AC outlet.
·Electrical Connection
Improper electrical wiring may invalidate the product war-
ranty.

described in the manual. Refer all servicing to qualified
service personnel only.
·Only use accessories/attachments or parts recommended
by the manufacturer.
·Warning
Please remember the high sound pressure do not only
temporarily damage your sense of hearing, but can also
cause permanent damage. Be careful to select a suitable
volume.

Characteristic
1. Stereo 4/8/6 channels MIC phone XLR input and LINE input
2. GAIN, BASS TREBLE, EFF in every channel
3. RCA stereo TAPE IN input and output
4. MASTER total volume and TAPE volume
5. EQ7 bands to adjust the circuit. (PM4200 do not have this function)
6. Reverberation has level volume, time volume, repeat functio. (PM4200 inside reverberation effect)
7. Building in power has functions such as time delay, over heat protection, short circuit, protection, direct current
protection and so on.
2. REVERBERATION: LEVEL is the phone reverberation effect to adjust the regulation resistance by return. Time is
the phone reverberation effect to adjust the regulation resistance by time delay. Repeat is the phone reverberation
effect to adjust the regulation resistance by the times of return. 0.1 second. especially when you play it with
microphone plug in, the digital delay performs better. Clockwise means increasing and contrarotate (PM4200 inside
reverberation effect) means decreasing.
Operation instruction
Front plate function instruction
1. INPUT: CHANNEL instruction. GAIN knob is to adjust the volume. BASS knob is to adjust the woofer volume; TREBLE
knob is to adjust alt volume. EFF knob is to adjust the reverberation volume, clockwise is to increase the volume,
and contrarotate is to decrease the volume. MIC is phone input, LINE is circuitry input
※ Please note that you only can use microphone input or line input, but you can't use microphone input and line input
at the same time.

4. Tape in is the audio input. Which can connect the DVD, MP3, computer and so on. the regulation resistance tape can
adjust the input volume. Tape out is REC output, using as record or as small signal source. And the regulation resistance
Master is the main volume. You can adjust the Master to control the output, Clockwise means increasing and contrarotate

1. Power is the electrical source switch. It's up means on and it's down means off. The indicator light of the power in the
front plate will be bright, when you turn on the electrical source. AC input socket with fuse is in the electrical source switch,
which can input the AC 230V/50Hz.Please change the same size if the protective tube is damaged.
There are two 6.35 JACK in the speaker cabinet which is output to connect the speakers. The impedance of adding two
speakers is no less than 4ohm.
