INSTRUMENT CABLE FOR A SPEAKER

Status
Not open for further replies.
Instrument cables have very small wires in them to transmit signal from your bass.

Then the AMPLIFIER AMPLIFIES that signal about 10 000 times more powerful.

So the speaker wire must be of a much bigger size to handle all that power well.

The greatest invention is "Speakon" connectors so people don't get confused on what cable to use.

I put a 1/2" wide ring of yellow heatshrink around the connectors for all the speaker cables as soon as I get them so that people can see which are which.

Doesn't stop them doing stupid things, but makes it less likely and removes any excuse.
 
Sound? Probably not. But it isn't safe. Speaker cable is a heavier gauge, and the conductors are different. Instrument cables are coaxial, a center conductor, surrounded by a braided shield (which serves as the ground). Speaker cable has two conductors of the same gauge (one pos, one neg) that may or may not be shielded with a braid (either way, the braid would carry no current).

I agree, Speakons or binding posts are the best kind connectors because the save the unknowing from themselves!
 
Wanna start a literal fire? Want to possibly destroy the amp? Speaker cable and instrument cables are NOT interchangeable. There are plenty of threads here on TalkBass that will clearly spell this out for you. A small-gauge center 'lead' conductor and a braided shield will not conduct high voltage transients without quickly heating up.

They lock too!

Yeah, I love them. No worry about a stupid techy walking through and tripping over it. (common happening at school performances). I had two amps running, one my practice amp and pointed at my drummer because their were no monitors and the acoustics in the auditorium were terrible, but I found out after the plug had been yanked out when a techy ran through. That would never happen to my Genz Benz

o, and to the op. Don't use speaker for instrument or instrument for speaker. They have different uses for a good reason. Mark your speaker cables to just in case.

Depending on the length, it can cause some power amps to oscillate (regardless of power level) and self destruct. CoAxial cable such as insturment cable generally has pretty high capacitance per foot which can cause the issues. Also, the smaller gauge wire mar cause heating of the conductor and insulation, not good.

Speak-ons are by far the best solution to all of this, meet all the international safety standards regarding touchproof contacts, rugged, locking, reliable and unlikely to be mistaken as an instrument cable by even the most techniclly challenged ;)
 
Won't hurt the cabinet unless the amp oscillates but doesn't blow up before damaging the cabinet, or damages the cabinet as a by-product of blowing up.
