What is Vizio Soundbar Input Lights

Vizio soundbar input lights are designed to indicate the current state of the soundbar. This should tell when you have your audio plugged in and if the soundbar can transmit sound.

These input lights are usually located on the front panel of the soundbar and can be useful for quickly identifying which input source is currently active. This is particularly helpful when you have multiple devices connected to the soundbar, such as a TV, gaming console, Blu-ray player, or streaming device.

There are typically four input lights on a Vizio Soundbar; HDMI 1, Optical, Bluetooth, and Other Inputs/HDMI 2. Each input source is assigned a specific color or pattern, and the corresponding input light will illuminate or flash to indicate the active source. Conversely, when the soundbar isn’t receiving any audio signal, the light will turn off. 

  • HDMI ARC (Audio Return Chanel)

Newer Vizio soundbars support HDMI input. These models come with a specified input light that comes with a specific color or pattern for this source which is commonly used for connecting the soundbar to the TV.

  • Optical Input

Although not every Vizio soundbar comes with an optical or digital optical input, if your model has one and it’s connected, there’s usually a unique input light to indicate its connection.

  • Bluetooth

During pairing mode, this input light is generally expected to be flashing, then become stable when paired. Also, the Bluetooth pairing light can either be a unique color from the other input types, or multiple colors.

  • Other Inputs

If you’re using a more recent Vizio soundbar model, you’re likely to have more than three input lights, and the fourth light will depend on your specific soundbar series and model. It can either be an aux-in, USB, or HDMI input.

Some models can come with a single light whose flashing pattern will indicate the kind of active input, and then there are others with individual input lights. While that’s the case, the specifics of the input lights and colors will vary by soundbar model. To know the precise one for yours, you’ll need to contact Vizio customer support or read your user manual.
