Disposing of used batteries with domestic waste is to be avoided!

Dispose of any unusable devices or batteries responsibly and in accordance
with any applicable regulations.

Batteries/NiCad cells often contain heavy metals such as cadmium(Cd),
mercury(Hg) and lead(Pb) that makes them unsuitable for disposal with
domestic waste. You may return spent batteries/accumulators free of charge
to recycling centres or anywhere else batteries/accumulators are sold.
By doing so, you contribute to the conservation of our environment!

We recommend the master volume control is turned to the maximum level. Next, adjust
volume of other audio input individually to avoid distortion with maximum dynamic range
output. Built-it audio limiter serves automatically to prevent the signal level from
exceeding a preset limit and stop sound from distorting.

Wired Dynamic Microphone

Minimize all volume levels before turning on the Master Power Switch . A lit red
battery indicator denotes rechargeable battery is charged. A flashing red battery indicator
denotes rechargeable battery is low on power. Simply plug the supplied power cord into
the power socket on the back and the other end into an AC power outlet to recharge the
battery. Amplifier can be used simultaneously during charging.

(1) Up to two

wireless receiver modules can be installed.

(2) Each receiver has built-in Pilotone & NoiseLock circuitry which reduces noise interferences.

(3) Unscrew the 2 screws from the MA-707-X filler panel and remove the filler panel before installing

the receiver module. After the screws and filler panel have been removed, insert receiver module
into the empty slot and push it back to it's mating connector. Uses the screws removed previously
to fasten the receiver module in position.

Manually Search for a Receiver Channel: Press and hold SCAN button to

perform a manual channel search. Existing channel blinks to denote it is ready
to accept parameter changes. During blinking, press and hold Channel button to
force the channel to go forward to the next channel in order. Release Channel
button until a desired channel is located. This new channel is now saved. If
Channel button is not pressed within six blinks, it stops blinking and reverts back
to the existing channel, Fig. 7.

(D) Perform the channel synchronization between the receiver and transmitter by power

on the transmitter microphone and pressing the Channel sync ACT button and bring
the ACT windows within 30cm of each other. Once channel is synchronized
successfully, the RF signal indicators are lit and Audio signal indicators expands
and contracts, pending how loud the input sound.

(A) Do not attempt to change a new receiver channel during a performance where two or

more transmitters/microphones are being used simultaneously to avoid interferences
with each other generated by the transmitting microphone signals.

9. Caution:

Ⅳ. Power Supply

1. AC Power Supply:

(A) Connect AC Power Cord Socket and plug the system into an AC outlet to charge

the built-in rechargeable batteries. The AC Power and Battery Status Indicator
blinks red during charging. The AC Power and Battery Status Indicator glows red and
stops blinking when it is fully charged.

(C)

CAUTION: AC Power push button needs to be pressed (recessed) when
plugging the system into an AC outlet. The system cannot provide AC power
if the AC Power push button itself is raised.

2. DC Power Supply:

(A) Two built-in series connection model WP 4.5-12 lead-acid batteries are used.

(B) Fully charged batteries will yield approximately 7 hours of continuous music and

speech. However, service times vary depending on control settings.

( ) AC Power push button needs to be pressed (recessed) when plugging the system

into an AC outlet for battery charging. The system cannot provide AC power if the AC
Power push button itself is raised.

( ) The Battery Charging Status Indicator will not glow unless Master power is

turned on. The LED light on Master power glows red when turned on denotes normal
status. The LED light on Master power flashes red when turned on denotes battery
low status. Simply plug into an AC outlet to recharge the battery. The LED light on
Master power do not glow or flashes red (light is off) when turned on denotes over-
discharged, abnormal or faulty status.

E Always store system with the batteries fully charged. To preserve built-in battery life,

we recommend to fully charged before the first use and after each use. Leave the
system plugged into an AC power outlet when not in use. Battery may not hold a
charge if they are not recharge often. Recharge the system at least once every 3
months. Remove the batteries when the system will not be used for an extended
period of time.

( )

(B) AC power provides powers to both the system itself and to the built-in rechargeable

batteries. Power switches to DC automatically from AC if the AC plug is detached
during operations. Operation works normally in both AC or DC mode. DC power
works only if it has built-in rechargeable batteries.

Portable Wireless PA System

Caution: AC and DC Power supply cannot be used at the same time.

(F) How to “rescue” rechargeable battery that is not used for a long time, not recharged

properly, stored in extremely high temperature environments, resulting in excessive
discharged and charging failure? First step, remove the battery and charge it by
18V/2A DC power supply for more than 30 minutes and ascertain battery surface
temperature cannot exceed 50℃ during charging. Then, install the battery back into
the system and turn on the power. The LED light on Master power flashes red
after powered on denotes battery can be recharged normally. If the LED light on
Master power is not on once powered on, it denotes battery can no longer holds a
charge, therefore, a replacement new battery is required.

Ⅴ. Installation of MIPRO CD/MP3 Media Player

(B) Gently insert the MP3 media player module into the slot. Make sure the back edge

connector is aligned and firmly connected.

2. Operations of CD/MP3 Media Player: See a separate player manual

enclosed in the master carton.

(A) Using a Phillips-head screwdriver (not supplied) remove the screws to remove

protection cover panel.

Installation Steps:

Ⅵ. Helpful Operating Tips

Minimized the master volume control before powering on. Adjust the

volume controls afterwards.

2. Each audio input volume can be individually controlled and mixed out

through the amplifier.

3. Each audio input can be broadcasted and recorded at the same time.

7. Refer to operating instructions for wireless microphone system.
8. Refer to actual product in the event of product description discrepancy.

6. Detached the power cord from AC power outlet once the system is fully-

recharged.

9. Frequency range, output power and maximum deviation to comply with the

regulations of different countries.

4. This PA system can be installed with an optional wireless microphone

system.

5. We recommend placing sound system between the target audience and the

presenter, facing the audience and raised above their heads using an
optional speaker stand or table stand. This set-up helps prevent the
annoying feedback by keeping wireless & wired microphone users behind
the sound system. The internal power supply rechargeable batteries should
be kept fully charged. Always charge the system after use.
