4.2 Automatic Pairing

The Vimo C3 system is designed for automatic pairing. When the transmitters and receiver are removed from the charging case, they will automatically power on and attempt to pair with each other. A successful connection is indicated on the receiver's IPS display.

4.3 Connecting to Recording Devices

The Vimo C3 offers wide compatibility with various devices:

• DSLR Camera: Use the provided 3.5mm TRS-TRS audio cable. Connect one end to the receiver's output port and the other end to your camera's microphone input.
• Smartphone/Tablet: Use the provided 3.5mm TRS-TRRS audio cable. Connect one end to the receiver's output port and the other end to your smartphone's 3.5mm headphone/microphone jack. For devices without a 3.5mm jack (e.g., newer iPhones, USB-C Android phones), a compatible 3.5mm to Lightning or 3.5mm to USB-C adapter (not included) is required.
• Computer: Use the provided 3.5mm TRS-TRRS audio cable. Connect one end to the receiver's output port and the other end to your computer's microphone input. Some computers may require a 3.5mm TRS-USB sound card (not included).

5.5 Output Modes (Mono, Stereo, Safety)

The Vimo C3 receiver supports three output modes:

• Mono Output: Mixes the sound from both transmitters (A and B) into a single track.
• Stereo Output: Outputs the sound from transmitter A to the left channel and transmitter B to the right channel, allowing for independent editing.
• Safety Output: Splits the sound into two tracks, with one track 6dB lower than the other. This lower track serves as a backup in case the main track peaks.

Note: Stereo and Safety audio tracks are not supported when using a 3.5mm TRRS to Lightning/USB cable.

  • Activate the noise cancellation feature on the transmitter.
  • Ensure the windmuffs are properly installed when recording outdoors or in windy conditions.
  • Check for potential interference sources (e.g., Wi-Fi routers, other wireless devices).
  • Adjust the gain levels on the receiver to prevent clipping or low volume.
• Connection Issues:
  • Ensure transmitters and receiver are fully charged.
  • If pairing fails, place all units back into the charging case for a few seconds, then remove them to re-initiate automatic pairing.
