Most RCA audio cables that are built reasonably well with shielding can be run effectively from 100 to 200 feet.

What would cause an amp to smoke?

An amplifier can blow (causing smoke) in a number of ways: The output is shorted – this drives as much current as the power supply can output (often > 400A) through the output transistors, causing them to fail.

Do RCA cables make a difference?

Yes, quality RCA cables will provide a noticeable improvement over cheap cables.

Is HDMI better than RCA cables?

Both RCA component and HDMI work well, but of the two, HDMI is the better choice. It’s a single cable for both audio and video hook-up that delivers superior video quality, surround-sound audio quality, 3D support, and more, verses using many wires using RCA component connections.

Well, an optical cable won’t “go bad” in the sense of wearing out or corroding, but it can break, which has pretty much the same result. Such a cable is little more than a bundle of glass or plastic fibres and if you bend one of them too far, it snaps like a piece of vermicelli. Click to see full answer.

Do long RCA cables degrade sound?

Unbalanced leads (standard RCA’s) do have a finite length limit. You may be able to get away with long leads with high level signals. Any cartridge will not sound its best with long TT leads.

How far can you run AV cables?

With a standard definition video signal (such as a regular DVD player, VCR, etc) you can reach cable lengths up to about 100 feet if you are using a high quality cable. If you are transmitting a high definition video signal then the maximum distance we recommend is about 16 feet.

Can a blown amp be fixed?

However, there are a few basic problems that can cause a car’s amplifier to sound like it is blown that consumers can fix with limited technical knowledge and no special tools.

How can you tell if an amp is blown?

How do you Figure Out that your Car Amplifier is not Working Properly?There is a noticeable distortion in the sound.There is no sound even if you have already turned on your audio system.Your stereo system starts making bizarre sounds such as farting sounds.

Which is better RCA or XLR?

In a nutshell, a balanced interconnect has some sonic benefit over unbalanced. In equipment where you have both options, it’s wise to chose XLR over RCA. … You will likely see more balanced cables with XLR connectors, because they are generally more common for balanced audio for this very reason.

Do cables go bad?

Cables, especially ones of high-quality like the ones Cable Matters sells should not simply go bad, as long as you treat them well. There is nothing about a cable which inherently means it will break down. They aren’t typically exposed to dangerous elements, corrosive materials, or strenuous wear and tear.

Do optical cables fail?

One of the most common problems with an optical audio cable is breakage. The breakage occurs inside the protective sheath and is not easily visible to the naked eye. If your cable stops working, there’s a very good chance that this will be the cause. Unfortunately, the cable can be broken easily.

Can I use yellow RCA cable for audio?

A typical RCA connector on a cable can be used to transmit audio or video. Usually the yellow end denotes composite video (all the signals combined for the video), and the red and black ends are for audio, but it doesn’t matter – that is just to help you hook them up properly; a color code for you.

Why is my amp not getting any power?

If the remote turn-on wire doesn’t have power, your amp won’t turn on. … If it doesn’t, you’ll want to check for any inline fuses and verify that the wire isn’t loose, corroded, or shorted out somewhere. If the remote and power wires both check out okay, the next thing to look for is continuity on the ground wire.

Do RCA interconnects matter?

The only quality that matters is that the cables are assmbled well with good compontents and proper sheilding.

How do I fix my RCA jack on my amp?

For repairing a broken RCA input socket on the amp: Remove all of the screws found at the bottom of amp. Flip it over and remove the top metal cover. Look inside and find the broken RCA input connection. … Get a soldering iron and reheat the points from the RCA connector onto the PCB board.

How do you check RCA output with a multimeter?

1) Set your multimeter tool to read in AC volts. 2) Ensure that the volume on the car stereo is almost turned up fully. This will send a strong signal to the RCA’s for it to be picked up more easily. 3) Using the probes measure the ac voltage from the centre pin and the outer ring.

What is the RCA output on a amp for?

RCA cables (line-level connections) are the preferred way to connect a signal to your amp if you have that option. RCA jacks on the rear of a Pioneer head unit. This is the ideal way to connect your amplifier’s signal inputs, if available. For a 4 channel amplifier, you’ll need 2 stereo RCA cables to do so.
