Question: Hi, for installation of new smart TV which requires connections such as HDMI & AV to gaming consoles, and outlet for power, is there a way to have all the functionality/connections on a recessed wall box?

Yes, absolutely! You can achieve a clean, recessed look for your TV connections using a recessed wall box. Here's how

Understanding the Components and Approach
Recessed Wall Box (Media Box)

This is the core component. It's a plastic or metal box that's installed inside your wall cavity. It provides a space to run and terminate your cables and typically includes a power outlet.


Power Outlet

You'll need to have a dedicated power outlet inside the recessed box. This is usually achieved by running new wiring from a nearby outlet or the breaker panel.

Important: This electrical work should be done by a qualified electrician to ensure safety and code compliance.
Low-Voltage Plates & Pass-throughs

These plates fit inside the recessed box and have connectors like HDMI, component video (AV), Ethernet, etc. The cables from your gaming consoles plug into these plates inside the recessed box. On the
other side of the wall, they connect to the back of your TV. Alternatively, you can use a blank plate and run wires through a small hole in it, known as a pass-through.

Cable Management

Inside the wall cavity, you'll run your cables (HDMI, AV, Ethernet) behind the wall from the recessed box up to the TV. You'll either need another recessed box behind the TV or use a cable entry plate with a brush to hide the cables.

Steps for Implementation
1. Planning and Location



TV Placement

Determine the exact location of your TV on the wall. This is crucial as it will dictate where the recessed box should be placed.


Gaming Console Location

Decide where your gaming consoles will be located (e.g., on a media console below the TV). This will determine the cable lengths you need.

Height

Place the recessed box low enough so it's easily accessible and hidden behind the TV (mostly) once the TV is mounted.


Wall Studs

Make sure you can fit the recessed box between wall studs. Standard stud spacing is 16 inches on center. Most boxes are designed to fit within this space.2.

Choosing the Right Recessed Box



Size

Get one large enough to accommodate all the cables you need (power, HDMI, AV, Ethernet). Consider future needs as well.


Features

Look for a box that includes:

Knockouts

Pre-made holes for running electrical wiring (for the power outlet).


Low-Voltage Mounting Plates

Places to install your HDMI, AV, and other connectors.

Depth

A deeper box can provide more room for cable management and bends, which is crucial for thicker HDMI cables.


UL Listing

Ensures the box is safety-tested and certified.3.

Electrical Work (Hire an Electrician)



Power Outlet Installation

A licensed electrician
must install a new power outlet inside the recessed box. They will run wiring from an existing outlet or the electrical panel, install the outlet, and ensure it's properly grounded.4.

Installation (General Steps - refer to the specific product instructions)



Cut the Hole

Using a drywall saw (or oscillating multi-tool), carefully cut a hole in the wall according to the dimensions of the recessed box. Use a stud finder to make sure you don't cut into a stud.

Run Low-Voltage Cables

Run your HDMI, AV, and any other cables you need
through the wall from the recessed box to the location of your TV. You will need to have a way to terminate the cables behind the TV.

Secure the Recessed Box

Insert the recessed box into the hole and secure it according to the manufacturer's instructions (usually with screws or clips).

Terminate Connections

Connect your HDMI, AV, and other cables to the appropriate low-voltage plates
inside the recessed box.5.

TV Mounting and Cable Management



Mount the TV

Mount your TV to the wall using a wall mount appropriate for your TV size and weight.

Connect Cables

Connect the cables from the TV to the ends that are in the recessed box behind the TV.


Cable Management

Use zip ties, Velcro straps, or cable ties to neatly organize the cables behind the TV and inside the recessed box.

Important Considerations and Tips
Code Compliance

Electrical work
must comply with local building codes. This is why hiring a qualified electrician is essential.

Cable Length

Measure carefully to ensure you have enough cable length to reach from the gaming consoles to the TV, including the distance running inside the wall. It's always better to have a little extra slack.

High-Quality Cables

Use good quality HDMI and other cables to ensure optimal picture and sound. Consider "future-proofing" with cables that support the latest HDMI standards (e.g., HDMI 2.1 for 4K/120Hz).


Conduit (Optional but Recommended)

For easier future upgrades or replacement of cables, consider running your low-voltage cables inside a flexible conduit within the wall. This allows you to pull new cables through without tearing open the wall again.

Fishing Cables

You might need to use fish tape or a cable rod to help pull the cables through the wall, especially if there is insulation.


Drywall Repair

Be prepared for minor drywall repair if the hole isn't perfectly sized for the recessed box or if you need to adjust the placement.

Products to Consider



Recessed TV Media Box

Search online retailers like Amazon, Home Depot, or Lowes for "recessed TV media box" or "in-wall TV power kit." Brands like Legrand, DataComm, and Arlington are common.


Low-Voltage Plates

You can find HDMI, AV, Ethernet, and other plates from the same retailers.*

Cable Management Accessories

Zip ties, Velcro straps, cable combs, and other organizers.

In summary:
A recessed wall box is a great way to clean up the wiring for your smart TV and gaming consoles. Proper planning, careful installation (especially the electrical work), and attention to cable management will result in a professional-looking and functional setup. Don't hesitate to consult with a qualified electrician and/or home theater installer for assistance. Flag for review
