Operating Instructions

Mic Pro supports professional-grade Linear Timecode (LTC / Audio-TC), enabling precise synchronization across multiple cameras and audio sources. By outputting timecode as an audio signal, it allows post-production software to automatically align footage, significantly enhancing workflow efficiency for film, interviews, and live broadcasting.

Enabling Timecode

Swipe down from the top of the Receiver home screen to enter the Control Center. Tap the Timecode icon; if it displays OFF, tap it to switch to ON. Once activated, the timecode will start running. Tap the refresh icon on the right to reset and restart the timer.

Timecode Sync Modes

Once Timecode is activated, four sync mode options are available:

• N/A

The Receiver acts as an independent clock source for internal timing only, with no external input or output. In this mode, timecode synchronization only applies to connected Transmitters—ideal for internal recording when external camera sync is not required.

• L-IN（Line In）

Used to receive an LTC signal from an external timecode generator (e.g., Tentacle Sync, Deity TC-1) to perform a Jam Sync. The Receiver will automatically detect and synchronize with the external master timecode.

• L-OUT（Line Out）

The Receiver outputs a Linear Timecode (LTC) signal to external devices.

• A-OUT（Audio Out）

The Receiver outputs timecode in Audio-TC (ATC) format.

Notes:

• The timecode signal occupies the Left Channel, while the Right Channel preserves standard audio (vocals/ambient). These tracks can be separated for processing in software such as DaVinci Resolve.
• Use a 3.5mm TRS cable to connect the Receiver’s 3.5mm output to the camera’s microphone input (digital cameras may require a Mic Adapter). L-OUT mode is generally recommended.

Frame Rate Settings

1. Select a frame rate that matches your camera’s actual recording settings.

For multi-camera synchronization, the frame rate on all recording devices must be identical to ensure successful alignment in post-production.

2. After saving the settings, the Receiver will automatically output the timecode as an LTC audio signal.

Caution: Since timecode occupies one audio channel, always perform a short test recording to ensure your vocal tracks are captured correctly.

Notes:

• Ensure your Receiver is running the latest firmware (update via the Insta360 app).
• We recommend recording a 10–30 second test clip before every shoot to verify that the timecode is correctly embedded in the audio track.
• If your camera does not support native LTC metadata, you can still achieve synchronization using the recorded audio track in post-production software.
