It sounds dodgy to me. You should get it checked out by a professional to be on the safe side.

It really sounds that the house wiring is at fault and, like others said, get a professional to have the entire house wiring route check up before it is too late to regret.

RE: Shielding Speaker Cables - ** HOW **

thaks foir the feedback

 

i've lived in the house for 10 years. about 2 years ago the wiring circuits were routinely inspected and i have a safety certificate.

 

The question is

CAN I SHIELD SPEAKER CABLES FROM ELECTRICAL INTERFERENCE and

WOULD THAT SHIELDING ACTUALLY DO ANYTHING BENEFICIAL.

RE: Shielding Speaker Cables - ** HOW **

There should be absolutely no need to shield any cable if it has been proberly constructed.

No difference.

However,from reading this post, it does appear you have a much more serious problem to be addressed first.

GET YOUR ELECTRICS CHECKED OUT AND STOP OBSESSING ABOUT YOUR SPEAKER WIRES!!  :wall:

Most radio frequency electromagnetic shields work by placing an a barrier of conductivce material between the object that you want to shield and the electromagnetic field that you're trying to shield it from.

 

It is possible to bodge an RF shield yourself but I'd advise against it. If you want to use screened cables you should buy some new cables that are properly screened such as these: http://www.superfi.co.uk/p-2665-chord-carnival-silver-screen-speaker-cable.aspx

A screened cable will reduce the amount of RF interference that the analogue signal picks up.

 

I doubt that a shielded cable would help your problem though. I don't know what's tripping your mains trip switch but it doesn't sound like something that would be caused by RF interference. It does sound like it could be potentially dangerous though and you should get a professional to check it out.

Yes you could although it wouldn't be easy but I can't imagine it would do anything beneficial.  As others have suggested it sounds like you have something much more serious going on that you need to have checked by a qualified electrician.

PS IMO your problems are much more likely to be being caused by a fault in your speaker wiring.

Covenanter,

PS IMO your problems are much more likely to be being caused by a fault in your speaker wiring.

See his original post. He has already changed out speaker cables, so unless both cables have the same fault, it is not them that's the problem Smile

It could be if he is wiring them incorrectly!  Cross connecting or connecting in serial for example.  We've seen a number of posts to this forum where people clearly don't know how to wire speakers correctly.  You can change the wire as many times as you like it won't correct incorrect wiring.  Kiss

You can do it, but there isn't any benefit.

RE: Shielding Speaker Cables - ** HOW **

------------

thanks guys - it is appreciated

------------

I am trying once again to power it all froma different circuit in the house.

I will get a sparky in.

 

follow on question

 

1. What is the sparky actually checking for? As I said I already have a basic certificate which shows there are no shorts and everything wired correctly on the house's various circuits.

2. The speaker cables and amp are centimetres away from the MAIN HOUSE FUSE BOX (modern) and presumably the mains power going into that - can that create any interference that may be the problem?

remember the power amp or a repalcement connected to no source with any of 2 correctly wired speaker cable sets with a set of correct resistance resistance or a nother pair of speakers can replicate the prob so it CANNOT be the equipemnt. it must either be main related or related to the proximity of the equipment to something

RE: Shielding Speaker Cables - ** HOW **

just wait for the sparky to come round and show him what happens with the amp and let him take it from there.

RE: Shielding Speaker Cables - ** HOW **

@cheeseboy ty

another thought crossed my mind

 

i've run an extension cable from a different ruing main...still does it.

it only happens occasionally and is not repeatable...prob when the sparky comes (luckily i know one who lives 4 doors away!!)

 

one thought tho. i run a Pc and pre and power amp and dac all from the same socket on an extension lead. might that be a prob eg could it be the PC doing something that causes it to need more power that causes the amp to lose power???? i have them all on an extension lead as the extension lead has some sort of circuit breaker and filtering in it before you say i'm mad!!

 

i'm going to try putting the power amp into a socket of its own

RE: Shielding Speaker Cables - ** HOW **

Sounds like you are overloading that ext. lead. You may be better to get the sparky to put in a new socket, no switches, just for the hifi.

RE: Shielding Speaker Cables - ** HOW **

Sorry if a slight highjack? Speaker and mains shouldn't run alongside but surely they usually will. Mine do! Is there any point in shielding in this circumstance?
