Frequently Asked Questions (FAQs)

1. Is an interconnect cable the same as a speaker cable?

While there isn't much difference between interconnect cables and speaker cables, interconnect cables serve a wider range of purposes. For example, they can be used to link a stereo or video game system through High-Definition Multimedia Interface (HDMI) cables.

2. How important are interconnect cables?

Interconnect cables, whether for speakers or RCA connections, play a crucial role in passing audio signals with purity and fidelity while rejecting interference that can introduce noise. Using high-quality interconnect cables allows your audio system to perform at its best and faithfully reproduce the source material.

3. Can you use interconnects as speaker wire?

Interconnect cables are not suitable for use as speaker wires, instruments, or microphones. They lack adequate shielding and have small conductors. Using interconnect cables for these purposes can introduce noise interference and potentially damage your equipment, especially speakers.

4. Can you use a subwoofer cable as an interconnect?

Yes, you can use a subwoofer cable as an interconnect, especially for long run RCA connections. There should be no issues using a subwoofer cable for this purpose.

5. How long should interconnect cables be?

The recommended length relationship between inexpensive interconnect cables and speaker cables is approximately (inter) = 4+0.343(spkr) in feet. As a general rule, inexpensive interconnects should be 1/3 the length of 11AWG ZIP speaker cables or shorter.

6. Does interconnect cable length matter?

Yes, the length of interconnect cables can affect sound quality, although the extent to which this is true may vary depending on the specific situation.

7. Can you run RCA and speaker wire together?

Yes, you can use RCA connectors on speaker wires if you need to. Speaker wires, often referred to as 'Zip cord,' do not specify the type of connectors on the end, so you can put an RCA connector on the end of your speaker wires if required.

8. What type of cable is suitable for connecting speakers?

Copper is the most commonly used material for speaker cables due to its low cost and low resistance. However, it is important to ensure that copper speaker cables are well covered and insulated to prevent oxidation.

9. Are RCA connectors obsolete?

RCA connectors, with their familiar red, white, and yellow connectors, continue to provide reliable and cost-effective connections for audio and video devices. While they may not be as popular as they used to be, they are still widely used, although non-RCA formats like HDMI cables have gained popularity.
