PANEL DESCRIPTION
■When Installing the Amplifier
DO NOT installing or mounting the amplifier in unstable locations, such as on the
rickety table or the slanted surface. It may result in the amplifier falling down and
causing body injury and/or property damage.
Be sure to ground to the safety ground (earth) terminal to avoid electric shock.
Never to ground to a gas pipe for tragic disaster may occur.
Use the amplifier only with the voltage specified on the amplifier. Using the
voltage higher than specified may cause fire or electric shock.
DO NOT cut, twist, damage, nor modify the power supply cord. In addition, avoid
using the power cord close to heaters, and don’t place heavy object, including the
amplifier itself, on the power cord, for it may cause fire or electric shock.
DO NOT expose the amplifier to rain or the environment where it may be splashed
by water or other liquids, for doing so, it may cause fire or electric shock.
WARNING

■When using the Amplifier
When found following irregular situation during amplifier is in use, immediately switch off
the power, disconnect the power supply plug from the AC outlet. Don’t try to operate
the amplifier again. Contact your local dealer to check the amplifier.
The amplifier falls.
Amplifier is malfunction.
Water or any metallic object gets into the amplifier.
The smoke or strange smell coming from the amplifier.
The power supply cord is damaged, such as exposure of the core, disconnection etc..
DO NOT put cups, bowls, or other containers with liquid or metallic object in it on the
top of the amplifier. If they spill accidentally into the amplifier, it may result in fire or
electric shock.
DO NOT touch the power supply plug during thundering and lightning, for it may result
in electric shock.
DO NOT insert or drop the metallic objects or flammable materials into the ventilation
slots of the amplifier, for it may result in fire or electric shock.
DO NOT open nor remove the amplifier cover to prevent fire or electric shock, for
there are high voltage components inside the amplifier.
PANEL DESCRIPTION
■When Installing the Amplifier
DO NOT remove nor plug in the power supply plug with wet hands, for it may cause
electric shock.
When unplug the power supply cord, be sure to grasp the power supply plug. DO
NOT pull on the cord itself. Operating the amplifier with damaged power supply cord
may cause fire or electric shock.
Avoid installing the amplifier in humid or dusty places, the area exposed to the direct
sunlight, locations generating smoke or steam, or the spot near the heaters. It may
result in fire or electric shock.
When moving the amplifier, be sure to remove its power supply cord from the wall
outlet. Moving the amplifier with the power cord connected to the outlet may cause
damage to the power cord, and resulting in fire or electric shock. When removing the
power cord, be sure to grasp its plug to pull.
DO NOT block the ventilation slots of the amplifier chassis. It will cause the
temperature rising and result in fire.
CAUTION

■When Using the Amplifier
Make sure that the volume control is turned to minimum position before power is
switched on. Loud sound produced at high volume when power is switched on may
impair hearing.
DO NOT place heavy objects on the amplifier, for it may cause it fall and may result in
body injury and/or property damage. Besides, the object itself may cause damaged
or body injury.
DO NOT operate the amplifier for the extended period of time with the sound distorting.
It is an indication of malfunction, which can cause heat and result in fire.
Switch the power off, and unplug the power supply plug from the AC outlet for safety
purposes, when cleaning or leaving the amplifier unused for 7 days or more. Fire or
electric shock may occur.
If the dust accumulates on the power supply plug or in the wall AC outlet, fire may
result in. Clean it periodically. In addition, make sure the plug is inserted in the wall
outlet securely.
Contact your local dealer to clean thedust, it the dust has accumulated in the amplifier
for a long period of time. Dust accumulation may result in fire or damage.
2.Description
MG-***2E series is the echo dual mixing amplifier of output power 200Wx2, 100Wx2,
60Wx2 and 30Wx2 in one unit designed for two different spaces application, such as 2
floors, or 2 zones.
There are totally 6 inputs, including 4 microphones, 1 AUX, and 1 CD/Tuner/Tape
(selectable) inputs.
For convenient to operate, CD/Tuner/Tape input selection switch and its level control are on
the front panel. One additional MIC 1 input is also on the front. All other input and output
level, volume, and tone controls are on the front. MIC1 has first level VOX priority over
other input.
One the rear there are two speaker screw terminals. Each one has low impedance 4 ohm
and 8 ohm, and high level 70V and 100V. Choose only one of these output connections to
match the speaker. Furthermore, each channel has record output.
To ensure the amplifier safety, it has speaker short, over temperature, and over load
protection. Besides AC power source, MG-***2E series has DC 24V input power screw
connector as backup power source.
MG-****2E series is ideal and convenient dual amplifier for the application of multi-input.

4. Power Source
AC Power Source
The supply transformer has been designed for use on either 115Vac or 230Vac,
selected by a push switch on the rear panel. The amplifier is factory set at 230Vac mains
voltage.
DC Power Source
Battery Connection (24Vdc)
When using external batteries, earth the amplifier via the screw terminal because of the
high voltages present. Electrical stability of the system is increased by earthed the case.
NOTE: The connection cable must be fitted with an in-line fuse; suggest to using
quick-blow type F15A. When Connect batteries, please ensure correct polarity.
5. Connection
Microphone Connection
Mic1~4 inputs are unbalanced standard 1/4” stereo jack on the rear panel. Mic1 has
additional input jack on the front panel for convenient operation.

CD/Tuner/Tape Connection
The equipment provides one CD/Tuner/Tape input, which may be used for connecting
other signal sources such as a Radio Tuner, CD or Cassette player. A selection switch
is located on the front panel. Select the desired source using this switch. Beside it is
its level (volume) control. And turn it clockwise to increase the volume or anticlockwise
to reduce the volume.
TheAux input sockets are standard RCAstereo jack, sockets are supplied and these
are linked together internally, this allows stereo signal source to be used without the
need to obtain a special lead. However, you may check with the manufacturer of the
signal source to ensure that no damage will occur if the left and right output channels
are connected in parallel.
Loudspeaker Connection

There are two speaker output screw terminals. Each speaker output screw terminal
allows connection of the standard low impedance of 4Ωor 8Ω loudspeakers, or 70V, or
100V line loudspeaker. Use only one of these output connections for corresponding
speaker for each channel.
Record Out
It is for the use of record, when it is demanded. Both two channels have their own record
out.
6. Operation
Level/Volume Control
On the front panel, there are 4 level/volume controls for microphone 1~4, 1 for AUX input,
and 1 for CD/Tuner/Tape. For the output, each channel has its own volume, treble, and
bass control. Echo Delay Control., Echo Repeat Control, Echo Repeat Control Adjust them to what
you desired.
