Complete range & accessories, covering small to large venues and from 50 up to 10,000 crowds. Even wireless interlinking systems up to 2 kilometer range.

MIPRO is an original designer and manufacturer with 40 years in producing wireless microphone & wireless portable PA systems.

Ascertain both receiver and transmitter have the same Frequency Bands (example, 6A-6A, 6B-6B, 6C-6C) "ERR 03 or 04" will appear on ACT-30H or ACT-30T transmitter when ACT (sync) button is pressed and cannot be synced due to incompatible bands.

Volume control of MRM-70-R & portable PA should be positioned at approx. 10-12 o’clock. Portable PA & MRM-70-R have individual volume controls.
MA-708 or MA-808 has a master volume control with indicators (green LEDs) and volume needs to be manually adjusted each time the system is powered on.

Once the receiver‘ACT’ (sync) button is pressed, the receiver channel LED starts to blink and is seeking to sync/pair channel with the transmitter. Ascertain to align transmitter IR window (red circle-shaped) with ACT IR window on the receiver and are facing each other within 30 cm (12-inch) range and within 5-7 seconds period. If sync is done successfully the receiver channel LED stops blinking.

Unknown external interference may cause unsuccessful synchronization. To change channel, press ‘SCAN’ button once to activate and press one more to scan for an open, interference-free channel. Repeat "A5" to sync receiver & transmitter frequencies.

Some external interference sources occurred different times during the day, thus, synchronization may work in the morning and not in the afternoon, vice versa. The interference maybe too strong if you are unable to perform the synchronization successfully with all 16 channels. You may have change to a new Frequency Band.

Up to 100-meter (330-feet) line-of-sight is possible. MIPRO is a wireless microphone specialist, original designer & manufacturer. Actual range depends on many variables, including RF signal, reflections, interference, crowd size, obstacles, metallic enclosures and placement of receiver.

With nearly 30 years of wireless design know-how, MIPRO is able to design built-in antennas and maintan highly reliable RF reception. An external or removable antennas can get lost or broken when the system falls down. A permanent, concealed antenna cannot be lost or broken.

Handheld microphone sounds the best. But if you need both hands free, you will have to wear either headworn or lavalier microphone and use a bodypack transmitter. Headworn microphone generally sounds better than Lavalier microphone, especially dealing with feedback issue.

Yes. Simply plug a MIPRO MU-40G guitar cable into your guitar or other instruments and plug the connector on the other end into an ACT-30T bodypack transmitter. Open the bodypack transmitter cover and switch to “GT” (line-level) mode from “MT” (microphone level). MT is the set mode for any MIPRO bodypack transmitter.

When you power on the transmitter the 4-level battery indicator is lit. A full 4-level meter denotes a full battery life.

For optimum reception, line-of-sight (clear of obstacles in between) should be maintained between the PA system and the transmitters.

Place the portable PA on a speaker tripod stand or higher ground and away from metallic objects & surfaces, computers, digital & electrical equipment and lighting systems will aid from external interferences and improved reception quality.

Ensure the SENSITIVITY level switch on MRM-70 or MRM-72 receiver is not positioned clockwise to the left-hand side (denote with negative "-" sign). This "-" negative position reduces sensitivity level and will also shorten the transmission range

For improved range, ensure the SENSITIVITY level switch on MRM-70 or MRM-72 receiver is positioned near to the right-hand side (denote with plus "+" sign) as possible. However, this may increase the chance of external interferences.

Audible noises and red-color “NOISE” indicator & RF meter are lit on MRM-70 or MRM-72 receiver module to indicate the presence of interference.

Press “ACT” to sync the receiver frequency to transmitter automatically.
or Adjust and reduce the "SENSITIVITY" level on MRM-70 or MRM-72 receiver clockwise to the left-hand side (denote with negative "-" sign). However, the reduced sensitivity level will also shorten the transmission range.

If both methods can not overcome interferences, detach and replace the receiver module with a different frequency band along with transmitter.

Solution is possible via multiple MIPRO MTM-90 wireless interlining transmitters and MRM-70 receivers. For exact set-up configurations please click “application”in MA-708 or MA-808 wireless PA system for detailed diagram

Use a foam windscreen over the handheld, headworn or lavalier microphone. The windscreen also reduces the annoying popping noise.
