What the Bose XLR Transmitter Does
The WT-XLR transmitter attaches directly to the XLR output of a dynamic microphone or balanced audio source.

Step-by-Step Setup Guide
Step 1: Pair the Transmitter
Power on the Bose S1 Pro Plus. Insert the transmitter into the wireless charging dock located on the rear panel of the speaker.
The pairing process begins automatically and completes within a few seconds.
Step 2: Select Mic or Line Mode
The transmitter can operate in two modes:
- Mic Mode – used for dynamic microphones
- Line Mode – used for mixers or line-level audio devices
Select the correct mode before connecting the transmitter.
Step 3: Connect the Microphone
Attach the transmitter to the base of the microphone using the XLR connector.
The transmitter replaces the traditional XLR cable connection.
Step 4: Turn On the Transmitter
Press the power button on the transmitter. The LED indicator confirms the device is active.
The S1 Pro Plus automatically receives the wireless signal on the paired channel.

Integrated Charging and Storage
The S1 Pro Plus includes built-in storage ports that hold and charge the wireless transmitters.
