Factors To Look For When Buying The RCA Cables
There are few factors that directly influence the quality of these cables. It will affect the signal transmission property of the cables a lot.
Always, check for these factors when buying new RCA cables
There are numerous materials used for creating the RCA cables. These materials are copper, silver, nickel, tin, zinc, and gold.
Silver and copper are very good for the best electrical conductivity and are affordable too. The gold wires are very expensive.
All other materials are not widely used today that’s why finding appropriate connections for them will be difficult.
There are many shielding that is used for RCA. This shielding increased the quality of the signal transmissions between the TV and the receiver. They also provide an extra layer of protection and can last longer.
Choose the right length of the RCA cables. Don’t buy short ones as they will not reach the destination.
Don’t buy too lengthy wires that, will make it difficult for you to manage it afterward.
First, measure the distance of the source from the AV receiver and buy them according to that measurements.

Precautions To Take For The RCA And General Connections
- Check twice as they are plugged correctly. Loosely plugged wires will affect the sound and video quality.
- Check the quality of each cable in the entire system once a month. Damage wires can affect signal transmission and can also give shocks to living things. If two wires touch each other, it will short the AV receiver.
- Run cables away from other electric devices to avoid their electric and magnetic field interferences with them.
- Properly manage the wires, so the back end of the system doesn’t look messy.
- Try to use as lesser wires as possible. If you are considering an RCA connection then go with the composite connections.
RCA cables can give you good quality audio and video but can not give the best quality as HDMI does.
If your system is not having HDMI connections, then don’t worry these connections can work fine for you.
