That is so the electrons know which way to flow  So then electrons are female? Because if they were male they wouldn't want to follow any map. |

Serious answer: the arrow points to the end where the shield is connected to the ground (outer ring of an RCA cable.) This end should be connected to the load, not to the source, to best help eliminate ground loops. It has absolutely nothing to do with "directionality" of signal flow as this does not exist in audio.

In an RCA cable, isn't the shield also the "return" path of the signal? Having the shield discontinuous, would force the return signal to find another ground path to return, causing a ground loop. A broken shield in an RCA results in a weak signal and hummmmmmm.
You are perhaps thinking of an XLR cable where the signal paths are independent of the shield. In which case, the shield should be lifted at the source end.

A properly shielded RCA cable uses three conductors: signal, ground and shield (also called SDW cable.) So no, although it is the same theory as in an XLR cable. The shield and ground are tied together at one end.

Or, in Audioquest cables the arrow indicates the direction of the grain in the copper.

I took apart my amplifiers and reversed the direction of each piece of hook up wire.
Then the fuse.
Remarkable improvement in imaging, soundstaging, frequency response extension, damping, transient response, and "slam" (whatever that is).
My wife, who was walking by the room and never notices my system said "what did you do? It sounds like the singer is in the room"
Highly recommended.

I think you would have had better results if you had alternated the wires!!  |

This the correct answer. As the electrons don't care where the aero points.  ? |

Oh, you're right!
I'll get right at it.
By the way, I also am using 10 gauge speaker wire for an AC power cord, with startling results!

Where should we really connect the arrow in short? Should the arrow be in the signal flow from the AVR to sub which means the arrow must be connected to the sub or the other way around?

The arrow is telling you to connect the cable according to signal flow. In this case the signal is flowing from your AVR to your SUBWOOFER. Said another way, the AVR output's the signal to the SUBWOOFER's input.

This is mostly correct directional cables have only one end of the shield connected to the ground. However normally the end that is connected to ground is the source, while the end at the receiving component is where the shield is disconnected. The arrow points away from the source and toward the next component. While it's true some people do reverse this order, the general rule is to always aim the arrow as though it was with the flow. Like so: CD Player >--------> Receiver/Processor >----------> Amp Receiver/Processor >--------> Subwoofer |

I thought that as long as the shield was connected to only one end (to a device connected to the ground) it would do it's job right and avoid ground loops, what end does not matter. Maybe I'm wrong, more of this here archive.oreilly.com/pub/h/4241. As to the grain direction of the copper due to lamination : first you'd need to believe that it does make a difference, at audible frequencies, then you would need to believe the cable manufacturer is able to manufacture cables by respecting the lamination direction of each strand. I heard from a manufacturer that this was impossible industrially, cables were always folded in the braids so strands inside a cable always go in both directions. Maybe special brands do their braids specially, but that was from an audiophile company already (even if I don't remember which one) so they would know about copper braids manufacturing... I read on a forum while researching my reference (that I didn't find) that the arrow was there as a reminder that the cable was burned in in that direction, since it's better to use it in the direction it's been burned in. Sure! |

It means, people are VERY gullible and/or marketing tactics can be VERY imaginative.

You have a directional cable. The area should be pointed North so that the sound will be properly oriented.
Warning: Do not try this South of the equator!
