How to Connect Multiple Retro Consoles to One TV with an AV to HD System Selector

Quick Answer

To connect multiple retro consoles to one TV, use an AV to HD system selector that accepts composite or component inputs and outputs HDMI. Connect each console to the selector's inputs, then run a single HDMI cable to your TV. This setup lets you switch between consoles without constantly swapping cables.

If you have more than one retro console, you know the pain of crawling behind the TV to swap cables every time you want to switch from the NES to the Dreamcast. An AV to HD system selector solves this by letting you plug all your consoles into one box and then run a single HDMI cable to your TV.

This guide walks you through the process step by step, from choosing the right selector to wiring everything cleanly. We'll also point out common mistakes along the way so you can avoid them and get back to gaming sooner.

Why Use an AV to HD System Selector?

Modern TVs rarely include the composite or component inputs that retro consoles use. An AV to HD system selector converts those analog signals to HDMI, so you can connect your NES, SNES, Genesis, or Dreamcast to a modern display. It also acts as a switcher, letting you connect multiple consoles at once and toggle between them with the press of a button.

The main benefit is convenience. Instead of unplugging and replugging cables every time you want to play a different system, you leave everything connected and just switch inputs. This reduces wear on your console ports and keeps your setup tidy. Most selectors also include a remote control, so you can switch without getting up from the couch.

• Check that the selector supports the number of consoles you plan to connect.
• Make sure it outputs HDMI if your TV lacks analog inputs.
• Some selectors also upscale the signal, but don't expect perfect image quality from composite sources.

Choosing the Right Selector for Your Setup

Before you buy, count how many consoles you want to connect. Selectors come with anywhere from two to eight inputs. If you're just starting out, a four-input model gives you room to grow. Also consider the type of output your consoles use: most retro systems output composite (yellow, red, white), but some like the Dreamcast can output component or VGA with the right cables. Make sure the selector supports the connections you need.

Another factor is whether the selector upscales the video. Basic models simply convert the signal, which can look soft or blurry on a large modern TV. More advanced selectors include upscaling to improve sharpness, but they cost more. For many players, a simple converter is fine, especially if you're playing on a smaller screen or don't mind the retro look.

• If you plan to use S-Video or component, verify the selector has those inputs.
• Consider a selector with a remote if your setup is far from your seating area.
• Read reviews to see how well the selector handles different consoles.

Gathering the Right Cables

Each console needs its own AV cable, typically composite (RCA) or S-Video. If you don't have the original cables, third-party replacements are widely available. Make sure the cable matches both the console's output and the selector's input. For example, a Dreamcast uses a proprietary connector, so you'll need a Dreamcast AV cable that ends in composite or S-Video.

You'll also need one HDMI cable to connect the selector to your TV. If your selector has multiple outputs, you could connect it to a capture card or second display, but for most setups, one HDMI cable is enough. Keep cable lengths in mind: if your consoles are across the room, you might need longer cables, but try to keep them as short as possible to avoid signal degradation.

• Label your cables or use colored zip ties to identify which console each input belongs to.
• Test each console with its cable before connecting everything to the selector.
• If a console doesn't have a standard AV output, check if you need a special adapter.

Step-by-Step Setup Guide

1. Inventory Your Consoles and Cables: List every console you want to connect and the AV cable it uses (composite, S-Video, component). Make sure you have the correct cable for each system. Checkpoint: If a console lacks a cable, order one before starting.
2. Choose a Selector with Enough Inputs: Pick an AV to HD system selector that has at least as many inputs as you have consoles. Look for one that supports the video output types you need. Checkpoint: Count your consoles and compare with the selector's input count.
3. Connect Each Console to the Selector: Plug each console's AV cable into the corresponding input on the selector. Match the colors (yellow to yellow, red to red, etc.) and ensure a snug connection. Common mistake: Mixing up inputs or not pushing cables in all the way can cause no signal. Double-check each connection.
4. Connect the Selector to Your TV via HDMI: Run an HDMI cable from the selector's output to an available HDMI port on your TV. Note which HDMI input you use. Checkpoint: Turn on your TV and select that HDMI input to see if the selector's menu appears.
5. Power On and Test Each Console: Turn on the selector and each console one at a time. Use the selector's switch or remote to cycle through inputs and confirm each console displays correctly. Common mistake: If a console shows no signal, check that it's powered on and the AV cable is firmly connected. Also verify the selector is set to the correct input.
6. Organize and Label Your Setup: Once everything works, bundle cables with ties and label each input on the selector or the cables themselves. This makes future switching and troubleshooting easier. Checkpoint: Take a photo of your setup for reference.
