Once the OWS Monitor Earphone is in Bluetooth Mode and paired with your phone, open the HollyAudio App. The Connect screen for the OWS Monitor Earphone will appear on the app’s home page—tap Connect to begin the firmware update.

In this mode, both the 3.5mm jack and USB-C port are configured identically: the left channel carries a mix of all TX audio, while the right channel carries timecode signals. It is advised to connect the RX’s 3.5mm TRS output jack to the camera’s microphone input to feed timecode into the camera. When using wired monitoring, you will hear the mixed audio in the left channel and the timecode signal in the right channel. If you are using wireless monitoring, the timecode will not be audible in either OWS monitor earphone.
Important Note for Mode 1: The 3.5mm TRS headphone jack will not output either the mixed audio or the timecode signal if the “Wired Monitoring” option is not selected.

In this mode, the 3.5mm TRS output jack outputs a mix of all TX audio, while the USB-C port outputs the mixed audio on the left channel and timecode on the right. This mode is suitable for scenarios where the RX needs to send timecode to a device via USB, while the 3.5mm output can be used for audio recording.

In this mode, the 3.5mm jack output all TX audio (in stereo or mono ), while the USB-C port outputs timecode audio. This mode is designed for use when the TX is recording internally or when the RX is connected to another recording device. Please note that Mode 3 becomes unavailable if you have wireless monitoring enabled and have the camera connected via the hot shoe.



You can learn how to use the timecode feature by watching this video: https://www.youtube.com/watch?v=-nM_-mjanrQ
Note: This function is only compatible with lavalier microphones that follow the TRS standard, where the Tip and Ring are used for the microphone signal and the Sleeve serves as the ground.
We recommend manually lowering the audio input gain on your camera to an appropriate level.
