Using the Remote
Proper Placement
For the best surround sound experience, position the sound bar, subwoofer, and surround sound speakers as shown. The sound bar should be close to ear level.
Note: Do not block the subwoofer port.
Proper Placement —Front Surround Mode
In rooms where ideal placement of the surround sound speakers is not practical, you can also place the sound bar, subwoofer, and surround sound speakers as shown below. Front Surround Mode will utilize DTS Virtual:X to produce a virtual surround sound experience.
To use this placement, please refer to the Surround Sound mode setting
Mode & Level Settings
Press each setting button and use the Up/Down buttons to access the different settings. Each setting will be displayed on the remote control’s LCD display. The LED indicators will behave differently with each function.
Using Button Combinations
There are other functions that are triggered by different button combinations on the sound bar.
Programming the Sound Bar
You can program your sound bar to accept TV remote IR commands.
- Press the SETUP button on the remote, then use the Up/Down buttons to navigate to Prg Remote.
- Use the Next/Previous buttons to toggle through Learn Vol -, Learn Vol +, and Learn Mute.
Bluetooth Pairing
To pair the sound bar with a Bluetooth device:
- Press and hold the Bluetooth button on the sound bar or remote control for five (5) seconds.
- Search for the sound bar (VIZIO M51) using your Bluetooth device. For more information, refer to the user documentation that came with the device.
- Now you can play audio from your Bluetooth device. Volume can be controlled on both your source device and the sound bar.
NOTES: The LED indicators on the display panel on the front of the sound bar will light up sequentially from bottom to top and back again. Once the device is paired, the LED indicators will stop flashing.
Using Bluetooth Mode
- Your sound bar supports music streaming from devices with Bluetooth capability. (Device compatibility will vary, see your device’s documentation for more information.)
- Once you have paired your source device to the sound bar your device should remain paired (within range).
- If the source is changed back to Bluetooth, any paired Bluetooth device will reconnect automatically.
- If the input is changed, the Bluetooth device will disconnect.
Maximizing Signal
A Bluetooth signal has a range of up to 30 feet. Keep in mind that Bluetooth is a compressed audio format, so streamed music may lose some integrity when compared to a wired connection. Try the following if your sound quality is less than optimal:
- If you hear any break-up or disconnect while streaming music from your device, move the source device closer to the sound bar.
- Be sure that there are no solid obstructions in the line-of-sight between the sound bar and the source device.
- Other wireless devices can affect Bluetooth range, including wireless security cameras, wireless video baby monitors, cordless phones, and microwave ovens. Turning off or moving these devices may improve Bluetooth range.
NOTES: Your sound bar is not equipped with a microphone, so it cannot operate as a hands-free device for a smartphone.
WARNING: Reduce the volume levels on your device and on the sound bar before pressing Play. High volume levels can damage your hearing.
Connecting to a Voice Assistant
Your sound bar can connect to a Voice Assistant (VA) device through an AUX VA or Bluetooth connection. Once connected, your sound bar will now act as the VA speaker.
Features and Benefits:
- Voice Assistant Dedicated Input: VA can be active on the sound bar even if the sound bar is set to a different input with audio playing.
- Auto Muting: If playing audio from the sound bar, the VA will play over the original source audio for 10 seconds. If continued after the 10 seconds, the VA audio will mute the original source audio. Once the VA audio is stopped the original source audio will resume.
Setup Tips:
- If the VA audio is too low, adjust the volume from the VA device.
- If the start of the response from the VA is cut off, enable “Start of Request” from your VA app settings.
- To disable the VA function, use the display remote to turn the Auto VA feature to OFF. Refer to Auto VA on page 16 for more information.
Turn on the AUTO VA Settings:
- Press the Setup button and use the up/down buttons to go to the AUTO VA setting.
- Use the left/right buttons to change the setting to AUX/BT or BOTH (depending on how you connect)
Using the AUX VA Port to Connect
- Use a 3.5mm audio cable to connect the AUX VA port on the sound bar to an AUX port on your voice assistant device.
Using Bluetooth to Connect
- Press and hold the Bluetooth button on the sound bar or remote for three (3) seconds. Search for the sound bar (VIZIO M51) using your VA device app. For more information, refer to the user documentation that came with the device.
Advanced Setup
Connecting with HDMI ARC
HDMI cables transmit both audio and video.
To view video from these devices:
- Turn the sound bar on.
- Set the sound bar input to HDMI In.
- Set your TV input to the same HDMI port that the sound bar is connected to.
What is HDMI Audio Return Channel (ARC)?
- Using HDMI ARC, your TV can send audio to the sound bar using an HDMI cable.
- Connect your sound bar to your TV’s HDMI ARC port using an HDMI cable that is ARC compatible.
To connect using HDMI*:
- Connect one end of the HDMI cable to the HDMI 1 (ARC) port on the back of your TV.
- Connect the other end to the HDMI (eARC) port on your sound bar.
- From the AUDIO menu on your TV, change the Digital Audio Setting to Dolby Digital or Bitstream.
- From the SYSTEM menu, enable CEC and ARC (SAC)† functions.
- From the CEC menu, select Device Discovery to register the sound bar with the TV.
NOTES: If you want to use the TV remote to control the sound bar volume: Enable System Audio Control from the CEC menu.
Connecting a Subwoofer
The subwoofer has already been paired with the sound bar by VIZIO. However, the subwoofer may need to be re-linked to the sound bar if there is no sound coming from the subwoofer.

First confirm that the power LED is illuminated. Press and hold the ON/OFF button on the back of the subwoofer for 5 seconds. The LED on the back of the subwoofer will begin to blink. | Press and hold the Power button on the top of the sound bar for 5 seconds. The LED indicators on the front will flash 3 times. The subwoofer is now linked with the sound bar. |
Help & Troubleshooting
There is no power.
- Press the POWER button on the remote control or on the top of your sound bar.
- Ensure the power cord is securely connected.
- Plug a different device into the electrical outlet to verify that the outlet is working correctly.
There is no sound.
- Increase the volume. Press VOLUME UP on the remote control or on the top of your sound bar.
- Press MUTE on the remote to ensure the sound bar is not muted.
- Press INPUT on the remote or on the top of your sound bar to select a different input source.
- When using the Digital Optical input, if there is no audio: (A) try setting the TV output to PCM or (B) connect directly to your Blu-ray/other source, some TVs do not pass through digital audio.
- On digital inputs, the input LEDs will flash rapidly and announce “format not supported” if an unsupported format is present. Set the source to output PCM.
- Your TV may be set to variable audio output. Confirm that the audio output setting is set to FIXED or STANDARD, not VARIABLE. Consult your TV’s user manual for more detailed information.
- If using Bluetooth, ensure that the volume on your source device is turned up and that the device is not muted.
I hear buzzing or humming.
- Ensure all cables and wires are securely connected.
- Connect a different source device (TV, Blu-ray player, etc) to see if the buzzing persists. If it does not, the problem may be with the original device.
- Connect your device to a different input on the sound bar.
The remote isn’t working.
- Replace the remote batteries with new ones.
- Point the remote directly at the center of the sound bar when pressing a button.
- If using a Bluetooth connection, some of the buttons on the remote may not be supported by the streaming application.
