Timecode
Timecode is a time marker used to synchronize audio and video.
Supported timecode modes
Master Run: The main RX timecode is set to Master Run by default, managing the generation and synchronization of timecode within the group and with external devices. Auto Jam: The secondary RX timecode defaults to Auto Jam, periodically syncing by receiving the timecode and frame rate from the main RX and aligning with external devices.
Common video frame rates are supported, with 29.97 fps set as the default. Ensure all recording devices maintain identical frame rates during recording.
Timecode output type
- N/A: The receiver runs the timecode internally but does not output it externally.
- L-IN: Used to synchronize timecode from an external timecode generator to the receiver.

When the receiver receives timecode from an external device, EXT is displayed in the upper right corner of the screen. Tap SYNC to synchronize the timecode to other devices. Tap RESET to reset the timecode.
- L-OUT: The receiver outputs timecode externally in Linear Timecode(LTC) format.
- A-OUT: The receiver outputs timecode externally in Audio Timecode(Audio-TC/ATC) format.

• Mono
Tap to switch to stereo or quadraphonic.
Quadraphonic mode allows four transmitters to operate simultaneously, with each assigned to a dedicated audio track for streamlined post-production editing.

Quadraphonic mode is only compatible with certain PC software and DJI Mic Series Camera Adapter. For details, refer to the compatibility list on the official website. DJI Mic Series Camera Adapter is only compatible with Sony cameras that have an MI hot shoe.
• Audio Monitoring
Tap to select the monitor source and adjust the volume.
Gain
Tap to open the gain slider and move the slider to adjust the receiver output gain. If the sound is overexposed, turn down the receiver gain first.
• Lossless Audio
When lossless audio mode is enabled, the transmitter sends 48 kHz 24-bit uncompressed audio to the receiver, ensuring higher audio quality.
• Auto On/Off With Camera
When enabled, the receiver will automatically power on and off with the camera when connected to the camera via the 3 . 5 m m audio cable or camera adapter.
• Auto Off
The receiver will automatically power off when the receiver is not linked to a transmitter within 15 minutes after powering on.
Environment
Both modes support automatic frequency hopping between 2.4 GHz and 5 GHz bands. The difference lies in the operating frequency covered by the two modes in different environments.
The Indoors mode covers a wider frequency range and offers stronger antiinterference performance. However, due to the laws and regulations in some countries or regions, certain 5 GHz frequency bands can only be used indoors. Select the appropriate mode based on your local laws and regulations, as well as your actual indoor or outdoor environment.

| REC | II|II| | REC | ||||
| Low Power Auto Recording | Loop Recording | Storage | Vibration | LED Indicator | Auto Off | File Option |
| REC | eMMC | REC |
• Low Cut
When enabled, transmitter will cut off frequencies that are 100 Hz or below, thus reducing low-frequency noise and making for cleaner recordings.
Gain
Slide to adjust the transmitter input gain according to the real-time volume.
Reduce the gain when the level bar turns red to prevent audio distortion or clipping.
• Adaptive Gain Control
Automatic Mode: Ideal for environments with dramatic volume fluctuations. It smoothly handles volume fluctuations and suppresses sudden spikes, ensuring balanced and consistent audio output.
Dynamic Mode: It automatically adjusts the audio output's dynamic range based on changes in input levels, compensating for input that is too low or too high by increasing or decreasing the gain as needed, ideal for quiet indoor settings like studios.
• 32-Bit Float Recording
When enabled, the transmitter can independently record audio files in 32-bit float, which offers a wider dynamic range for audio post-editing.

Note that the recording time of the transmitter will be shorter when 32-bit float recording is enabled.
• Startup Auto Recording
When enabled, the transmitter automatically starts internal recording upon powering on.
• Low Power Auto Recording
When enabled, the transmitter automatically starts internal recording when the connected receiver or device/camera is low on battery.
• Loop Recording
When enabled, the system automatically splits recorded files at intervals during internal recording and overwrites existing files when storage is full.
• Auto Off
When enabled, the transmitter, when not connected to any device and without internal recording activated, automatically shuts down after 15 minutes of no use.
• File Option
Set the file type to Dual-File Internal Recording to retain the original audio file while integrating the enabled audio algorithms, simplifying post-production use without the need for additional processing.
Multi-Transmitter Control
If the receiver has joined a group as the main receiver, swipe up on the home screen to simultaneously control all transmitters in the group and start internal recording or noise cancellation.

Single Transmitter Control
Tap the transmitter status bar to access the dedicated control interface for that transmitter, enabling functions such as internal recording and muting.

2.2 Quick Actions with the Dial
