AC Power Switch: Switch must be pressed in order to activate charging of built-in MB-70
rechargeable batteries.
Master Power Switch: Turns AC/DC power on/off to the unit. The indicator glows when you
turn the power On. Please note that to avoid the over-discharging or stressing of the built-in
battery supply, it is recommended that you charge the unit immediately the LED indicator
flashes (to warn of low battery charge). Otherwise, the unit will turn off automatically once a
pre determined low charge level is reached (and this may interrupt your usage of the unit)
Extension Speaker Socket: Allows you to connect an optional MA-707-EXP extension
speaker for increased directional coverage. The MA-707-EXP is rated at 70 watts @ 4 ohms
and connects in series to the speaker in the MA-707.
DC Input Socket: Allows you to connect an external 24-32V DC power supply if required.
Please note that the polarity of the central pin in the socket is positive (+).
