How to pair the SYNCO Xtalk Master wireless intercom headsets?
SYNCO Xtalk Master wireless intercom headsets are pre-paired at the factory and ready to use. If additional headsets are added, all headsets need to be paired again. The following sections explain the pairing process for different headset counts.
If you have 2-8 headsets, pair using buttons or the app
For 2-8 Xtalk Master headsets, pairing can be done using the buttons or the app.
👉Pair using the A/B buttons on the Xtalk Master

If you have 9-40 headsets, pair them using the base station.
For a wireless intercom setup with more than 8 Xtalk Master headsets, the SYNCO XStation is needed for pairing. Follow these steps:
A. Press and hold the Pairing button on the XStation until the indicator turns solid red.
B. On each Xtalk Master headset, press and hold Buttons A and B. Release when you hear "Pairing Successful". Up to 20 headsets can be paired at the same time.
C. After all headsets are paired, press and hold the Pairing button on the XStation again to exit pairing mode.

If you need to pair 21-40 Xtalk Master, connect two XStation base stations using a Cat5e Ethernet cable. Once connected, the two base stations work together as a single communication system.

How to divide the SYNCO Xtalk Master into different groups?
The SYNCO Xtalk Master lets you organize headsets into 2-5 groups based on your team structure. Below, we’ll show you how to set it up in different ways.
If you need 2 groups, use the button on the Xtalk Master.
Xtalk Master uses Button A and Button B to switch between two groups. Users can join Group A, Group B, or both groups at the same time. The headset remembers the last group setting and automatically rejoins it after powering on.
To join Group A or Group B, press and hold Button A or Button B of the Xtalk Master headset. Release after hearing "Group A" or "Group B".

To exit Group A or Group B, press and hold Button A or Button B again. Release after hearing "Beep-Beep".

If you need 3-5 groups, use the app or base station.
For more complex workflows, you can use the SYNCO Audio App or the XStation to organize Xtalk Master wireless intercoms into 2-5 groups. The right setup depends on your team structure.
👉Dividing 2-8 Xtalk Master into 3-5 groups, use the app.
If you have fewer than 8 Xtalk Master headsets, you can use the SYNCO Audio App to manage 3-5 groups easily.
Watch the video below to learn how to assign Xtalk Master to different groups and use the Broadcast to One and 1-to-1 Chat features for more precise communication.
👉Dividing 9-40 Xtalk Master into 3-5 groups, use the base station and app.
For wireless intercom setup with 9–40 Xtalk Master headsets, group management is handled using both the XStation base station and the SYNCO Audio App. This setup helps you organize multiple teams more efficiently.
A. Press and hold the Pairing button on the XStation until the indicator turns solid red. Then press the desired Group button (A/B1/B2/B3/B4) to select the target group.
B. On the headset, press and hold Buttons A and B simultaneously. Release after hearing "Pairing Successful". Up to 20 headsets can be paired at the same time.
C. After all headsets are paired, press and hold the Pairing button on the XStation again to exit pairing mode.
D. Use the SYNCO Audio App to change the group setting. Refer to the video above.
