5.1 Mode transmissor (TX)

In TX mode, the adapter broadcasts audio from a connected source to other Bluetooth LE audio receivers.

1. Ensure the adapter is in TX mode.
2. Connect your audio source:
• Entrada AUX: Use the 3.5mm audio cable to connect your device (e.g., TV, computer) to the adapter's 3.5mm AUX input.
• Entrada MIC: Connect an external microphone to the MIC input for voice broadcasting.
• Entrada Bluetooth: Pair your Bluetooth device (e.g., smartphone) with the adapter.
3. Select the desired input source (AUX, MIC, or BT) using the corresponding buttons/indicators on the adapter.
4. The adapter will automatically begin broadcasting. Ensure your receiving devices (e.g., headphones, other BW-LE523 units in RX mode) are ready to receive.

5.2 Mode receptor (RX)

In RX mode, the adapter receives Bluetooth LE audio broadcasts and outputs them via its 3.5mm AUX port.

1. Ensure the adapter is in RX mode.
2. Connect your listening device (e.g., headphones, speakers) to the adapter's 3.5mm AUX output using the provided 3.5mm audio cable or earphone.
3. The adapter will search for available Bluetooth LE audio broadcasts.
4. Once connected to a broadcast, audio will be routed to your listening device.

5.3 Broadcast Modes (BIS/CIS)

The BW-LE523 supports advanced Bluetooth LE audio broadcast modes for different applications:

• BIS (Broadcast Isochronous Stream): Ideal for one-to-many audio transmission, such as tour guides, silent discos, or classroom settings. One transmitter can connect to multiple receivers simultaneously.
• CIS (Connected Isochronous Stream): Used for synchronized audio streams between a limited number of devices, often for specific applications requiring tight synchronization.

Use the BIS/CIS buttons to select the appropriate broadcast mode based on your needs.
