Disposal
Dispose of any unusable devices or batteries responsibly and in accordance with any applicable regulations. Disposing of used batteries with domestic waste is to be avoided! Batteries/NiCad cells often contain heavy metals such as cadmium(Cd), mercury(Hg), and lead(Pb) which makes them unsuitable for disposal with domestic waste. You may return spent batteries/accumulators free of charge to recycling centers or anywhere else batteries/accumulators are sold. By doing so, you contribute to the conservation of our environment!

II. Operating Instructions

Power On:
Minimize all volume levels before turning on the Master Power Switch(11). 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. The amplifier can be used simultaneously during charging.
Master Volume Control:
We recommend the master volume control is turned to the maximum level. Next, adjust the volume of other audio inputs individually to avoid distortion with maximum dynamic range output. A built-in audio limiter serves automatically to prevent the signal level from exceeding a preset limit and stop sound from distorting.
Line-input 25, and Line-output 24 6.3 0 (1/4″) Jacks:
(A) Reduce the Line Input volume levels 21 to a minimum. Once powered on, adjust master volume levels(19) to maximum, and adjust line input volume to the appropriate level.
(B) A line Output jack(24) combines all mixed audio. Volume levels are individually adjusted, and not related to master volume control.
Wired Dynamic Microphone:
(A) Reduce microphone volume levels to a minimum. Once powered on, adjust master volume levels 19 to maximum.
(B) Plug an unbalanced 6.3 0 microphone into MIC 1 Input 26 and adjust MIC 1 Volume Control e for desired sound level.
(C) Plug a balanced XLR microphone into MIC 2 Input 27 and adjust MIC 2 Volume Control e for desired sound level.
(D) Adjust Tone Control 20 for high or low tone sound quality.
(E) The wired and wired microphones can be used at the same time and mixed and output sound can be heard simultaneously.

Ill. Connection for External Audio Sources

IV. Power Supply

AC Power Supply:
(A) Connect AC Power Cord Sockets 16 and plug the system into an AC outlet to charge the built-in rechargeable batteries. The AC Power and Battery Status Indicator 15 blink red during charging. The AC Power and Battery Status Indicator glows red and stops blinking when it is fully charged.
(B) AC power provides power 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. The operation works normally in both AC and DC modes. DC power works only if it has built-in rechargeable batteries.
(C) CAUTION: AC Power push button 10 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.
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.
(C) AC Power push button 10 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.
(D) The Battery Charging Status Indicator15 will not glow unless Master powers11 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 denoting battery low status. Simply plug into an AC outlet to recharge the battery. The LED light on Master power does not glow or flashes red (light is off) when turned on denotes over-discharged, abnormal, or faulty status.
(E) Always store the system with the batteries fully charged. To preserve built-in battery life, we recommend fully charging before the first use and after each use. Leave the system plugged into an AC power outlet when not in use. The battery may not hold a charge if they are not recharged 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.
(F) How to “rescue” a rechargeable battery that is not used for a long time, has not been recharged properly, and stored in extremely high-temperature environments, resulting in excessive discharge and charging failure? The first step, remove the battery and charge it by an 18V/2A DC power supply for more than 30 minutes and ascertain battery surface temperature cannot exceed 50°C during charging. Then, install the battery back into the system and turn on the power. The LED light on Master 11 powers flashes red after being powered on denotes the battery can be recharged normally. If the LED light on Master power is not on once powered on, it denotes the battery can no longer hold a charge, therefore, a replacement new battery is required.
Caution: AC and DC Power supplies cannot be used at the same time.

V. Installation of MIPRO Receiver Modules

Each device allows up to two receiver modules to be installed. MIPRO offers different receiver modules, and users can select the proper one they desire.
Use a Phillips-head screwdriver (not supplied) to remove the screws and then the protection cover panel. Insert the receiver module into the slot. Push it a little harder and make sure the back edge connector is aligned and firmly connected. Then tighten up the screws.
Operations of the receiver modules: See a separate user guide enclosed in the master carton.

VI. Installation of MIPRO CD/MP3 Media Player

Installation Steps:
(A) Use a Phillips-head screwdriver (not supplied) to remove the screws to remove the protection cover panel.
(B) Gently insert the MP3 media player module into the slot. Make sure the back edge connector is aligned and firmly connected.
(C) Tighten up the screws.
Operations of CD/MP3 Media Player: See a separate player manual enclosed in the master carton.

VII. Helpful Operating Tips

Minimized the master volume control a) before powering on. Adjust the volume controls afterward.
Each audio input volume can be individually controlled and mixed out through the amplifier.
Each audio input can be broadcasted and recorded at the same time.
This PA system can be installed with an optional wireless microphone system.
We recommend placing the sound system between the target audience and the presenter, facing the audience and raising above their heads using an optional speaker stand 7 or table stand. This set-up helps prevent 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.
Detached the power cord from the AC power outlet once the system is fully-recharged.
Refer to operating instructions for a wireless microphone system.
Refer to the actual product in the event of product description discrepancy.
Frequency range, output power, and maximum deviation to comply with the regulations of different countries.
