Soundbar Position and TV Remote Sensor: Avoid Blocking the IR Receiver

What is an IR receiver and why it matters

Most TVs use an infrared (IR) receiver to pick up signals from the remote control. The receiver is a small window, usually on the front bezel, that must have a clear line of sight to the remote. When you add a soundbar in front of the TV, the soundbar can block that window, making the remote unresponsive or requiring you to point it at an awkward angle.

This is a common shopping question because soundbars are often placed directly below the TV on a stand or shelf. The height and depth of the soundbar determine whether it interferes with the IR path. For more on placement, see our guide on soundbar placement optimization.

How soundbar placement can block the sensor

A soundbar that is too tall or too deep can physically cover the IR receiver. Even if the soundbar does not completely hide the window, it may reduce the angle at which the remote can reach the sensor. This is especially true for soundbars with a raised center section or a built-in subwoofer that adds height.

The problem is more likely when the TV sits on a stand and the soundbar is placed on the same surface directly in front. Wall-mounted TVs give more flexibility, but the soundbar still needs to be positioned so that its top edge does not rise above the bottom of the TV bezel where the sensor is located. Read our soundbar table vs wall mount article for more on placement options.

How to find your TV's IR sensor location

The exact position of the IR receiver varies by TV model. It is often near the bottom edge, either centered or off to one side. Some TVs have a small dark window or a tiny LED that blinks when the remote is used. The quickest way to locate it is to look at the TV's manual or search for the model name plus "IR sensor location" online.

Once you know where the sensor is, measure the distance from the bottom of the TV to the sensor. This measurement tells you the maximum height your soundbar can have without blocking the receiver. If the soundbar is taller than that gap, you may need to adjust the placement or choose a different soundbar. See our soundbar width vs TV guide for related sizing tips.

Soundbar features that help avoid IR blockage

Some soundbars are designed with a low profile, meaning they are short enough to fit under most TV bezels without covering the IR window. When shopping, look for the height dimension in the listing or on the maker's page. A soundbar that is 2 to 3 inches tall is less likely to cause issues than one that is 4 inches or more.

Another feature is an IR repeater (sometimes called an IR blaster). This is a small sensor on the soundbar that receives the remote signal and passes it through to the TV. If the soundbar has an IR repeater, it can be placed directly in front of the TV without blocking the remote. Check the listing for words like "IR repeater," "IR blaster," or "remote pass-through."

You can also bypass the IR issue entirely by using a different control method. If your soundbar connects via HDMI ARC or eARC, the TV remote can control the soundbar's volume through HDMI CEC without needing a direct IR path. Similarly, many soundbars offer Bluetooth or Wi-Fi control through a smartphone app, which does not rely on line-of-sight at all.

What to pick for your situation

The right choice depends on your TV's design and how you prefer to control the system. The table below matches common scenarios to soundbar types that minimize IR interference.

Questions

Can I use my TV remote if the soundbar blocks the IR sensor?

It depends on how much the sensor is blocked. If the soundbar completely covers the window, the remote will not work. If only part of the sensor is blocked, you may need to point the remote at a steeper angle. Using HDMI CEC or an IR repeater solves the problem.

What is an IR repeater on a soundbar?

An IR repeater is a small sensor on the soundbar that receives the remote's IR signal and sends it to the TV through a cable or internal circuit. It allows the soundbar to sit in front of the TV without blocking the remote.

Do all soundbars block the IR sensor?

No. Low-profile soundbars that are shorter than the distance from the TV's bottom edge to the IR sensor will not block it. Soundbars with an IR repeater also avoid the issue. Many soundbars are designed to be placed under a TV without causing problems.

Can I use HDMI ARC to avoid IR issues?

Yes. When a soundbar is connected via HDMI ARC or eARC, the TV remote can control the soundbar's volume through HDMI CEC. This does not require a direct IR path to the TV. Check that both the TV and soundbar support ARC and CEC.

How do I know if my TV has an IR sensor?

Almost all TVs have an IR sensor for the remote. It is usually a small dark window on the front bezel. You can confirm by looking at the TV's manual or searching for the model name plus "IR receiver location."

What if my soundbar is too tall and I cannot move it?

You can try raising the TV slightly with a stand riser or placing the soundbar on a lower shelf. If that is not possible, consider a soundbar with an IR repeater or switch to HDMI CEC control.

Does a wall-mounted TV change the IR clearance?

Yes. With a wall-mounted TV, you have more freedom to position the soundbar lower on the wall or on a shelf below. Measure the distance from the bottom of the TV to the sensor and choose a soundbar that fits that gap.

Can I use a universal remote to avoid IR blockage?

A universal remote still uses IR unless it is a radio-frequency (RF) model. RF remotes do not need line-of-sight, but they are less common. Check the remote's specifications before buying.
