Speaker To RCA Converter – Best in 2023

RCA cables and connectors are generally acknowledged to offer high-quality audio signals. You’ll find them on  most stereo systems. RCA connectors split the audio signal into two, effectively creating a right side and a left side.

You’re probably familiar with the dual plugs for audio, one is red, the other is white. They can be used for inputting signals or outputting them. Most sound systems will offer an audio in and an audio out option, both via RCA connector. 

It should be noted that the color is irrelevant. It is merely an aid to ensure the right output is connected to the right input. Your cable will have some means of identification to ensure this is the case. If you don’t the signals will be confused and the sound won’t be right.

Despite huge advances in wireless technology, a wired connection remains the best way to connect devices and ensure the highest –quality signal possible.

However, there are still some devices that only have one audio output. For example, your phone outputs through one 3.5mm jack. It’s capable of replicating stereo sound but, in order to connect it to a stereo system you’ll want a speaker to RCA converter.

It is possible to connect with a single cable that has a 3.5mm jack on both ends. You’ll find your sound system has an audio in that this jack will fit into. But, you’ll only be using one channel of the sound system and you’re not going to enjoy the music as it should be.

Instead, a speaker to RCA converter will allow you to listen to your music through all the speakers attached to your stereo system. You can even add in an amplifier to boost the sound level.

Considerations When Choosing A Speaker To RCA Converter

It’s important to choose the right speaker to RCA converter. You only want to buy this device once and you need it to provide high-quality signals. That’s why it’s worth doing a little research before you buy.

  • Reputation

The first stage is to check the reputation of the manufacturer and supplier. The better known they are the more likely it is to be a genuine product that will perform well.

However, even the best manufacturers can make mistakes. That’s why you should look at product reviews and go on social media to see what others think of the specific speaker to RCA converter. 

You’re looking for mainly positive feedback although a few negatives are normal. This doesn’t just help to suggest the reviews are genuine, it also gives you the opportunity to assess how the manufacturer/supplier respond when things go wrong.   That’s as important as the quality of the product.

  • Price

RCA converters are not generally expensive so price shouldn’t be an issue. However, that doesn’t mean you shouldn’t look at the different prices to help you choose. The cheapest are not always the best quality. However, its also not the case that the most expensive are the best.

You’ll need to consider their reputation, your needs, and the price you’re willing to pay.  

  • Connectors

Gold-plated connectors are generally best for conductivity. You should focus on what material the connectors are made from as this will help to ensure the quality of the signal is maintained. As this directly translates into sound quality you want the best possible. 

You should note that it’s not so much the connectivity tat give gold-plated connectors the advantage, it’s the fact that they won’t corrode, maintain the quality when other connectors start to corrode and distort the sounds.

Pay attention to the converter’s quality, the RCA cable’s length, and the type of speaker wire compatible with the converter. 

Using RCA inputs with a passive speaker requires a preamp to boost the signal. A passive speaker to RCA converter uses your speaker’s existing wire to connect to your RCA input.
