High-frequency Noise Interference
High-frequency noise interference produces continuous high-frequency noise,
which deteriorates sound quality. All MIPRO microphone capsule modules have a
high-frequency noise interference prevention design.
High-frequency noise interference may occur when other brands’ microphone
capsules are plugged into MIPRO transmitters.
Notes
- Refer to the actual product in the event of product description discrepancy.
- The frequency range and maximum deviation comply with the regulations of different countries.
- Spraying alcohol directly onto the condenser capsule module will cause severe damage and invalidate the warranty.
4-Pin Microphone Input Jack Wiring
- 2-wire electret condenser microphone capsule connection.
- 3-wire electret condenser microphone capsule connection.
- Dynamic Microphone.
- Electric Guitar.
- Line-in (impedance 8K ATT 10cB).
