RX/Record mode
In addition to making traditional audio devices wireless through Bluetooth audio wireless transmission, you can also use the Type-C USB interface⑧ to connect a recording device for digital recording. It is recommended to record in the broadcast Bluetooth mode, because the broadcast Bluetooth mode adopts the latest LC3 decoding technology, and the recording quality is the best.
Please repeat the above steps of [RX/Receive Mode] to enable the broadcast Bluetooth mode to record.

Introduction to Bluetooth modes

1. Classic Audio (1-to-1)
   MoerDuo™ is backward compatible with non-LE Audio Bluetooth receivers. When the receiver is not a LE Audio device, it will connect using the traditional Bluetooth mode pairing method.

2. LE Audio (1-to-1)
   If the receiver is a Bluetooth device that supports LE Audio (including Bluetooth receivers, Bluetooth headsets, Bluetooth speakers, etc.), it will automatically use lossless/high-resolution decoding technologies to play music.

3. Broadcast audio (Auracast™) (1-to-N).
   Broadcast mode is only compatible with LE Audio devices, and there is no limit on the number of receiver-end devices. No pairing is required in broadcast mode, as long as MoerDuo™ broadcast mode is enabled, the receiver-end devices can search and connect by themselves (operating range up to 30~50 meters).
