Shenzhen Minghan Technology M1 Wireless Microphone Instruction Manual
Pair method
-
Transmitter settings, short press “Settings key” to enter the menu selection, set transmitter to A/B, channel CH-XX, The setup is complete.
-
receiver settings, short press “Settings key” to enter the menu selection, set the A/B device with the same channel as the transmitter, set When complete, the receiver’s A/B changes color, and the transmitter’s power display takes effect.
-
one drag two pairings, need to set the transmitter to A and B devices, respectively, to generate transmitter A and transmitter B, and the receiver to A and B the corresponding channel, you can automatically join success, as shown below.
Tip: When wireless signal interference is found, possibly due to a conflict in wireless frequency, try switching to a different channel to avoid interference frequency.
Volume settings
- The volume of the transmitter and receiver can be adjusted into the menu, it is generally recommended that the transmitter volume is set to 6,the pick-up effect is best.
- Receiver volume can be set according to the recording phone camera, should not be too large or too small, it is recommended to use volume 8.
- The transmitter is set to have a one-click mute function, the side down button can be switched.
| state | cause |
|---|---|
| It cannot be powered on | The battery is not charged, please charge the device. |
| No sound | Check that the transmitter and receiver are reversed and that the |
interface is external
Whether the device is correct.
The channel on the transmitter is different from the channel on the receiver
The transmitter and receiver are set to the same channel.
Wire use is wrong, please use the accessory camera and mobile phone With wire
.
The recording sound is too small| Adjust the volume of the transmitter and
receiver to the highest level of transmission throughout the signal path
without distortion
Get the best signal-to-noise ratio.
---|---
The microphone hole is blocked.
The sound is distorted| The volume between the transmitter and the receiver is
too high, reducing the volume between the transmitter and receiver, with the
goal of being in the entire signal path
Transfer the highest level without distortion for the best
signal-to-noise ratio.
The sound is noisy, the bag Current sound, low noise, pop sound, etc| Signal is disturbed
- Try switching channel
- Try recording indoors with less RF interference indoors
- Keep the transmitter at least 1 meter away from the receiver and away from conductive objects such as metal and water Overhead telephone lines, fluorescent lights, and metal fences can all interfere with wireless microphones Turn off all computers and phones nearby
The RF signal is weak
- Ensure that the line of sight between the transmitter and the receiver antenna is clear
- Your body, clothes, and stage set can all be a hindrance
- Make sure that the transmitter is within the operating distance of the receiver
- If there are obstacles, you may need to shorten the transmitter and connection
The distance of the receiver
The sound is noisy, the bag Current sound, low noise, pop sound, etc| The
input level of the camera, video recorder, or mixer is too high. Lower the
audio input level of the camera or recording device, lower the audio output
level on the receiver, and lower the low-key console gain.
If there is no function on the device that is adjusted or set, and the level
is Still high, adjust the volume of the transmitter or receiver
