A single red color indicator indicates the 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.

2. Master Volume Control

   • Master Volume Contreras two switchable modes. The standard mode resets to zero volume level after power is turned off. The memory mode saves and recalls the last programmed volume level by pressing and holding the specific volume indicator before power is turned off.
   • 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.

3. Line-input and Line-output RCA Jacks

   • Reduce the Line Input volume levels to minimum. Once powered on, adjust master volume levels to maximum, and adjust line input volume to appropriate level.
   • Line Output jack combines all mixed audio. Volume levels are individually adjusted, and not related to master volume control.

4. Wired Microphone

   • Reduce microphone volume levels to minimum. Once powered on, adjust master volume levels to maximum.
   • Plug an unbalanced 6.3 0 microphone into Unbalanced 6.3 0 Microphone Input and adjust MIC 2: Unbalanced 6.3 0 Microphone Input Volume Control.
   • Plug a balanced XLR microphone into Balanced XLR Microphone Input @nl and adjust MIC 1: Balanced XLR Microphone Volume Control .
   • Tone Control for high/low or Echo Control effect adjustments.
   • The Voice over Music Priority  feature mutes the volume of the played audio when it is switched to on and microphone is used. Feature is disable it is switched to off.
   • The wired and wired microphones can be used at the same time and sound can be heard simultaneously.

5. Wireless Microphones

   •  Reduce microphone volume levels to minimum. Once powered on, adjust master volume levels to maximum.
   • Power on the receiver module and reduce volume levels to minimum.
   • Perform the channel synchronization between the receiver and transmitter by pressing the Channel sync ACT button. Once channel is synchronized adjust to the desired volume levels.

Power Usage Instruction

1. How to use AC power input
   • After putting the power plug into the AC input socket of the device, the 4 battery meter indicators G) will glow immediately, no matter if the power switch is on or off. This means that the built-in switching power supply is functioning normally and the built-in rechargeable batteries are fully charged. If the battery meter indicators are blinking this means that the built-in switching power supply is working normally and the built-in rechargeable batteries are in an under charged condition. After a couple of minutes, the battery meter indicators will stop blinking and continue a glowing condition, indicating the batteries are now fully charged.
   • AC power provides power to both the unit itself and to the built-in lead-acid rechargeable batteries.
   • When using the AC power, you can remove or plug the power cord freely with no need to turn off the power switch first. If or when an unfortunate power cut happens during usage, the MA-708 will activate the DC power automatically to maintain continuous operation.
2. How to use DC power input
   • Two built-in series connection lead-acid batteries with models WP 4.5-12 are used. When the batteries are fully charged, the unit can be operated continuously for approximately 7 hours in standby mode (CD player and two receivers are turned on); 5~6 hours for audio and 3~5 hours for music. (The above figures are references for brand new batteries only)
   • The built-in rechargeable batteries can be recharged when the unit is plugged into an AC or DC power outlet.
   • In the case of no AC power connection, if the power switch ‘8 is not turned on, the battery meter indicators G) will not be shining. When the power switch is turned on, the red LED on it will be shining; meanwhile, if 2 to 4 battery meter indicators are shining, it means the battery power is enough for normal operation. The number of the shining indicators is in direct proportion of the battery power. If only 1 battery meter indicator is shining or the red LED on the power switch is sparking, it means the battery power is insufficient and immediate charge is necessary. If no battery meter indicators are shining after the power switch is turned on, it means the batteries are completely discharged or possibly faulty.
   • Always store MA-708 system with the batteries fully charged if needing to store the system for more than 3 months. Leave the system plugged into an AC power outlet when not in use.
   • The rechargeable batteries will not function properly if not recharged for an extended period of time. It is therefore, recommended to recharge after every use regardless of the usage time to preserve battery life.
   • If the battery is not used for a long time or not charged properly, even the storage temperature is too high, resulting in excessive discharge and charging failure, the first step is to remove the battery and charge it by 18V/2A DC power supply for more than half an hour and noted the battery surface temperature should not exceed 50 °C during charging. Then, reload it into the machine and turn on the power, if the battery indicator lights a red light, connect the AC power for normal charging procedure; if the battery indicator is completely off, which indicates that the battery has failed.

AC power and DC power can not be used at the same time. A connector is included which allows users to make DC wiring. See diagram below for illustration.
