The TCL Z100-SW wireless subwoofer can be paired directly to select TCL Google TVs using the TV’s Speaker Management (Z100) feature. Once connected, the Z100-SW adds deeper bass while allowing the TV speakers to continue playing audio.

This feature is currently available on the following TCL Google TV models:

• QM6K-QM6K Pro-QM7K-QM8K-QM9K
• QM7L-QM7L Pro-QM8L
• RM9L
• X11L

Before You Start

Make sure you have:

• A TCL Z100-SW wireless subwoofer
• The included AC power cord
• A compatible TCL Google TV with the Speaker Management (Z100) option
• A strong 5GHz Wi-Fi connection on the TV

For best performance, place the Z100-SW within 10 meters, or about 30 feet, of the TV during setup.

Note: The menu names and available settings may vary slightly depending on the TV model and software version.

Step 1: Connect the Subwoofer to Power

• Place the Z100-SW near the TV.
• Connect the included AC power cord to the subwoofer.
• Plug the power cord into a working wall outlet.

When powered on for the first time, the Z100-SW should automatically enter pairing mode. The LED indicator will flash or show a breathing effect to indicate it is ready to connect.

Step 2: Pair the Z100-SW with the TV

Using the TCL Google TV remote, go to:

• Settings > Display & Sound > Audio Output Settings > Speaker Management (Z100) > Pair and Manage > Add New Device
• The TV will begin searching for nearby compatible Z100 devices.
• When the Z100-SW appears on the screen, select it to begin pairing.

Important: Do not cast, open apps, change inputs, or use other TV functions while pairing is in progress.

Step 3: Confirm the Audio Output Setting

After the Z100-SW is paired, confirm that the TV is set to use the external subwoofer audio option.

Go to:

• Settings > Display & Sound > Audio Output Settings > Audio Output
• Select External Subwoofer if it is not already selected.
• This allows the TV to output audio through the Z100-SW and the TV speakers at the same time. 

Step 4: Complete Any On-Screen Setup or Calibration

After pairing, the TV may display additional setup or calibration prompts. Follow the on-screen instructions to complete setup.

For best results:

• Keep the room as quiet as possible during calibration.
• Do not move the subwoofer while calibration is running.
• Keep the subwoofer in the same location after calibration is complete.

If the Z100-SW Does Not Pair

Try the following steps:

• Make sure the TV is connected to a strong 5GHz Wi-Fi network.
• Move the Z100-SW closer to the TV.
• Confirm that the TV has the Speaker Management (Z100) option.
• Restart the TV and try pairing again.
• Unplug the Z100-SW from power, wait 30 seconds, then plug it back in.
• Press the pairing button on the Z100-SW, if needed, to place it back into pairing mode.
• Check the TV for available software updates.
• Remove any previously paired Z100 device from Speaker Management, then try pairing again.

Helpful Tips

• Pairing should be completed from the TV’s Speaker Management (Z100) menu.
• The TV should remain connected to the internet so available updates can install.
• The Z100-SW should be used within the recommended wireless range for the best connection.
• Directions may vary slightly by model and software version.
