FAQ - PORTABLE PA
Q: Why is my MA-707 not recharging (indicator is not flashing) when plugged into an
AC outlet?
A1: Ensure AC Power button is pressed in (next to the MRM-70 receiver module slot). An un-
pressed button (out) will prevent recharging of the battery.
A2: The rechargeable battery life has ended. Replaced with new, fresh rechargeable battery.
Q: How to adjust for optimal sound volume?
A: If the portable system has both Master & Microphone volumes, we recommend turning the
Master volume to about 3pm (clockwise) first and about 1~2pm (clockwise) for Microphone or
other volumes.
Q: How to prevent and minimize the annoying feedback?
A1: Do not stand directly in front of the speakers; keep mics away from speakers.
A2: Avoid pointing microphone towards the speakers.
A3: The microphones should be behind the speakers wherever possible.
A4: Locate the portable PA between the crowd and the presenters and facing the crowd.
A5: Turn down the sound level coming out of the portable PA / speakers if necessary.
A6: Place the speakers above the head of the crowd.
Q: What if I need more power to cover a larger crowd?
A: Two or more portables can be used with one wireless microphone transmitter. Ascertain that
the receiver frequency in each portable coincides with the wireless microphone.
Q: Can I play music through the systems?
A: Yes. All MIPRO portables have auxiliary inputs (3.5mm min-jack, RCA or 1/4”phone), which
will accept input from an external iPod, MP3, CD, cassette, VCR, DVD players. As well,
modular CD players can be inserted into most models.
