FAQ - PORTABLE PA
Q: How to adjust for optimal sound volume?
Q: How to prevent and minimize the annoying feedback?
Q: What if I need more power to cover a larger crowd?
Q: Can I play music through the systems?
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.
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.
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.
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.

A: Simply plug into a power outlet using the included power cable and adapter. “Flashing” LED
indicates it is charging. The main power switch can be on or off position during charging.
Microphones or music can be used during charging & power is on.
A: When Power LED is lit (MA-705 & MA-707) or Charge LED is lit (MA-101& MA-101a) or one
indicator remaining in battery meter (MA-202, MA-708, MA-808). Plug into a power outlet to re-
charge ASAP.
A: The batteries should have a life of approx. 2 years if used and maintained properly. Battery life is
determined by temperature, depth and rate of discharge, and the number of charges and
discharges (called cycles).
A1: Power LED indicator is not “lit” when power on. (No battery voltage).
A2: LED indicator or meter is not “flashing” when plugged-in.
A3: Getting 1~2 hours operating time per charge.
A4: When battery has been used extensively for 2~3 years or more.
