Overview

The WiiM Bar serves as the core of a 5.1.2 surround setup. It supports 3.0.2 channels on its own, and by adding a WiiM Sub Pro, and Surround Left and Surround Right speakers, you can expand it into a complete 5.1.2 surround sound system for a truly cinematic experience.

This article will walk you through the steps to set up a 5.1.2 surround sound system.

What You Need for a 5.1.2 Surround Sound System

  • 1 x WiiM Bar
  • 1 x WiiM Sub Pro
  • 2 x WiiM Sound/Sound Lite, or 1 xWiiM Streamer/WiiM Streaming Amplifier
    For example, use two WiiM Sound speakers as the Surround Left and Surround Right channels. Alternatively, connect two passive speakers to a WiiM Amp and use them as the surround channels.
  • A TV with an HDMI ARC/eARC port.
  • A Wi-Fi/Ethernet network
  • A mobile device with the WiiM Home app installed.

Set Up a 5.1.2 Surround Sound System

Step 1: Place Speakers Properly

For optimal sound, place all speakers according to the diagram below.

Tip: As the subwoofer does not emit highly directional signals, you can place it anywhere in the room.

Step 2: Connect the WiiM Bar to the TV

Connect the WiiM Bar to the TV via the HDMI ARC/eARC port. Make sure to use the HDMI port labeled "ARC/eARC". Using another HDMI port will not produce sound.

If the TV has no HDMI ARC/eARC, connect via the Optical port.

Note: When using the Optical connection, you cannot adjust the WiiM Bar's volume using the TV remote.

Step 3: Set Up the WiiM Devices

Set up the WiiM Bar, WiiM Sub Pro, and other WiiM devices using the WiiM Home app and connect them to the same network.

When setting up the WiiM Sub Pro, make sure to connect it to the WiiM Bar via wireless or wired connection mode. For details, see How to Set Up Your WiiM Sub Pro.

Step 4: Add Surrounds in the WiiM Home App

  1. Open the WiiM Home app on your mobile device.
  2. Go to the Devices tab > WiiM Bar's Device Settings > the Home Theater section.
  3. Tap the Surrounds setting. 
  4. Select the Surround Left (SL) and Surround Right (SR) speakers, then tap Next.
    Tip:
    • Choose two WiiM Sound/Sound Lite speakers or one WiiM streamer/streaming amplifier.
    • Tap the volume icon  next to each surround speaker to confirm you've selected the correct speaker.
  5. When the Setup Complete page appears, tap Next to check the surround speaker connections. 
  6. Tap Start to check the surround speaker connections. You can also skip this step and check them later. 

Once the 5.1.2 surround sound system is created, it is enabled automatically. Play audio on the TV and enjoy a truly cinematic experience.

Note: In case of no sound, make sure to switch the WiiM Bar to the correct input (HDMI ARC or Optical In).

Select a Sound Mode to Enhance Audio

The WiiM Bar offers four Sound Modes specifically for Dolby and DTS—Music, Movie, Voice, and Night—so you can quickly optimize audio for different content and listening environments. For details, see Understanding Dolby and DTS Sound Modes on Your WiiM Bar.

Simply select your preferred sound mode using the WiiM Bar Remote.

Manage the Surround Speakers

Once the surround speakers have been added, you can manage them at any time from the Surrounds settings in the WiiM Home app. For example, you can check their connections or remove them.

Check Surround Connections

We recommend checking the surround connections to ensure stable playback. If any connection is poor, refer to the recommended network setup in How to Keep Surround Playback Stable.

Remove the Surround Speakers

If you want to remove paired surround speakers from the WiiM Bar, simply tap Remove Surrounds.

You can then select new WiiM devices as your surround speakers.
