What to do if wireless remote control is not possible with Sony Microphone?
- J
  Jennifer MerrittAug 26, 2025
  If wireless remote control isn't working with your Sony Microphone, first ensure that pairing has been established between the microphone and receiver by carrying out pairing. Check the wireless remote control condition level. If it is low, decrease the distance between the microphone and the receiver. If the microphone was previously paired with another receiver, carry out pairing again with the microphone that you want to control on the receiver.

The Sony DWM-02N is a digital wireless microphone designed for use in UHF synthesized wireless microphone systems. It features an interchangeable microphone capsule unit, making it suitable for various applications such as vocal performances, interviews, and speeches.

Function Description

The DWM-02N is part of Sony's DWX series, which combines professional microphone expertise with stable wireless technology and cutting-edge digital audio. It supports multi-channel simultaneous operation, encrypted transmission, and metadata transmission for monitoring multiple transmitters. The microphone also offers remote control capabilities from a receiver via a main link and an additional link, potentially streamlining professional workflows. It utilizes WiDIF-HP (Wireless Digital Interface Format, High Profile), a Sony-developed digital audio interface format that ensures secure transmission, high sound quality, low system latency, and multi-channel operation.

Maintenance Features

Cleaning: For humid, dusty, or active gas environments, clean the surface and connectors with a dry, soft cloth after use. Avoid thinners, benzene, alcohol, or other chemicals.
Battery Replacement: Replace both batteries when the battery indication starts to flash. Check expiration dates of new batteries.
Environmental Considerations: Operate within 0 °C to 50 °C. Avoid operating near electrical equipment (motors, transformers, dimmers) or lighting equipment to minimize electromagnetic interference. Keep the microphone away from noisy places, air conditioning equipment, or public address loudspeakers.
Multi-Channel Operation: Maintain at least 30 cm (11 7/8 inches) distance from other transmitters/microphones. For digital-only systems, keep at least 4 m (13 feet) from a receiver antenna for up to 10 channels, and 6 m (20 feet) for 11 or more channels. For mixed digital/analog systems, maintain at least 6 m (20 feet) from a receiver antenna. For wide-area use without obstructions, keep 100 m (328 feet) from analog wireless systems using the same frequency.
Electromagnetic Interference Prevention: Turn off portable communication devices near the DWM-02N to prevent malfunction and audio interference.
