RODECaster Pro II to Canon Vixia Camcorder: Direct Audio Setup


This tutorial covers how to connect the RØDECaster Pro II to a Canon Vixia camcorder to capture high-quality podcast audio directly into your video recording. This setup bypasses the camcorder’s built-in microphone for significantly improved sound quality. This setup works great for videotaping your audio podcast.

What you're working with:

  • RØDECaster Pro II
  • Canon Vixia 4K Camcorder

Supplied Cables and Adapters:

  • Attenuator cable (-15dB to -25dB recommended) 

NOTE: Why the Attenuator Cable Matters - The RODECaster outputs a strong line-level signal, while the camcorder expects a much lower mic-level signal. The attenuator reduces this signal to prevent distortion and avoids the camera’s auto gain from causing audio to dip or “pump” during recording.

  • Dual 1/4" (male) to single 3.5mm (female) adapter (L + R)

  • 1/8" (3.5mm) male-to-female cable


Setup Instructions

  1. Mount the camcorder on a tripod and position your shot. Tip: Use the AC power cable instead of relying on battery power.
  2. Connect the dual 1/4" adapter to the Line Out ports on the back of the RODECaster Pro II.
  3. Connect the 3.5mm cable to the adapter.
  4. Connect the other end of the 3.5mm cable to the attenuator cable.
  5. Plug the attenuator cable into the camcorder’s mic input.
  6. Power on both the RODECaster Pro II and the camcorder.

Audio Settings

On the RODECaster Pro II:

  • Set output to Line Level
    • Tap the ⚙️ Settings (gear icon) on the touchscreen
    • Tap “Outputs”
    • Select “Line Outputs” (this is for the 1/4" jacks on the back)
    • Look for Output Level
    • Set it to Line Level (not Mic Level)

On the Canon Vixia:

  • Switch audio to Manual
    • Tap the Menu button on the touchscreen
    • Go to the Audio Setup (or Audio Settings) menu
    • Find “Mic Level” or “Audio Rec Level”
    • Switch from Auto to Manual
    • Adjust the level using the on-screen slider
  • Monitor audio levels while speaking

Note:  Avoid clipping. Aim for peaks around -12 dB on the camera meters.


Recommended Camera Settings

  • Resolution: Optional
    • NOTE: 4K produces very large files
  • Frame Rate: 24p or 30p
  • Shutter Speed:
    • 1/50 (24p)
    • 1/60 (30p)
  • Use manual exposure if possible
  • Lock white balance
  • Turn OFF auto gain (AGC) if available

Pro Tip: Always Do a Test Recording

  • Record 10–15 seconds
  • Play it back on both:
    • Camera
    • RODECaster backup
  • Confirm clean, stable audio before starting your session

Troubleshooting

No Audio in Camera

  • Check all cable connections (RODECaster → adapter → attenuator → camera)
  • Confirm the Canon VIXIA HF G70 is set to Mic Input (not internal mic)
  • Make sure audio is set to Manual, not Auto

Audio is Distorted or Too Loud

  • Confirm you are using an attenuator cable (-15dB to -25dB)
  • Lower the camera input level (start around 25–35%)
  • Check that the RODECaster Pro II output is not clipping

Audio is Too Quiet

  • Verify RODECaster output is set to Line Level
  • Increase camera input level slightly
  • Check that your source mics are properly gain staged

Audio “Fades” or Pumps

  • Turn OFF Auto Gain (AGC) on the camera
  • Make sure you’re using an attenuator cable
  • This issue is usually caused by the camera reacting to a signal that’s too hot

Audio Only on One Side (Left/Right)

  • Check your dual 1/4" to 3.5mm adapter
  • Ensure both left and right outputs are connected properly
  • Some adapters may sum incorrectly—test with headphones if unsure

No Signal from Wireless Mics

  • Confirm transmitters are powered on and paired
  • Check receiver output into the RODECaster
  • Verify the correct channel fader is up
