Connecting Your Old Amplifier RCA to a New TV with Optical and HDMI Connections
It's often the case that you have an old, cherished amplifier with RCA inputs, while your new television has only optical or HDMI connections. Here's a comprehensive guide on how to connect your amplifier to your TV for high-quality sound.
Step 1: Get a Proper Converter
The first thing you need is a converter that can handle the digital audio from your TV. If your TV has an optical (TOSLINK) out, you need a converter to convert this digital signal to the analog signal your amplifier can understand. One popular option is a converter like the XXBU Audio Converter (example model), which supports digital audio TOSLINK input and stereo analog output via RCA.
Note that this converter will need power, either from a basic 5W AC adapter or from a USB port found on some smart TVs. If your new TV has a USB port, you can use it to power the converter. If not, you may need to get an additional 5W AC adapter.
Step 2: Locate the Optical Output on Your TV
Start by finding the optical output on your TV, which is typically marked as TOSLINK. This is the socket that sends the digital audio signal from your TV to the converter.
Step 3: Check Your Stereo System
Next, check your stereo system to see if it has an optical input. Many modern amplifiers do have optical inputs, which is the best option for high-quality sound. If it does, all you need is an optical cable to connect the two. However, if it doesn't, you may need to consider the alternatives below.
Option 1: Conventional Digital to Analog Converter
If your stereo system doesn't have an optical input, you can opt for a digital to analog converter (e.g., the Digital to Analog Converter (example model)). This small, powered box converts the light pulses from the optical connection into the analog stereo signals (RCA red and white) that your amplifier can recognize.
Option 2: Include a Remote Control
There are also converters that come with a built-in remote control, which can be convenient if you prefer not to change the volume every time. For example, the AAU Converter with Remote (example model) offers this feature.
You can also get converters that support multiple inputs, like the Dual Input Converter with 6 Line-Level Inputs (example model). This allows you to connect multiple optical sources, eliminating the need to use the TV as an intermediary.
Step 4: Connect the Signal to Your Stereo System
Depending on the age and capabilities of your gear, you might have audio in via RCA jacks or a 5-pin DIN connector. Once the signal is converted, connect it to your stereo system using the appropriate RCA cables. RCA cables are typically red and white, with the red cable being the right channel and the white cable being the left channel.
Step 5: Set the Audio Standard on Your TV
Finally, you need to set the audio standard on your TV to get the best sound quality. Most modern TVs have a setting that allows you to choose between different audio outputs, such as PCM (Pulse-Code Modulation). Go to the TV's menu and navigate to the Audio or Audio Settings section. You'll need to select PCM as the audio output standard. If you're unsure, refer to the TV manual for specific instructions.
After making this selection, your external audio equipment should produce high-quality sound. However, if the selection isn't correct, the gear you've connected may either produce no sound or a crackling noise. Make sure to double-check your settings until you hear the clear, stereo sound you're looking for.
That's it! With these steps, you should be able to enjoy high-quality sound from your new TV and your cherished old amplifier.
By following these instructions, you can ensure that your audio setup works seamlessly, providing you with the best possible sound experience.
Stay organized and refer to your manual when needed. Proper installation and setup can make a significant difference in your audio experience.
Good luck!
