    Speaker Hissing, and connections info

    Hi All

    Currently I connect my LCD to HIFI speakers using a wire where both ends are red/white connectors.

    However, there is a slight hissing sound, and because I know its there, it annoys me!

    It is a cheapy wire from maplin, would it make a difference if I got a premium gold special wire etc etc?

    Cheers

    Yes, best going for gold plated connectors.

    You don't need to spend a fortune though.

    Just as gold plated SCART and HD leads are better as it carries the signal better with less distortion.

    It's ever so difficult to diagnose speaker problems without being "in situ" as it where.

    Cheap wire won't necessarily cause a problem.

    Are you running the speakers through an amp or direct from the LCD TV ?

    I know some wires are worth paying more for, not sure for this case.

    Its directly from TV to HiFi system

    The only wires that dont matter how cheap they are are digital ones. So its always better to buy premium ones in the case of phono cables and scart leads ect.

    Have you tried running the speakers through an amp first ?

    Are you using the correct OHM speakers for the TV ?

    Agreed but do you think that would be an issue in this situation ?

    I dont have an amp.

    Im playing whatever is on the television through the hifi speakers by connecting from the TV to the HiFi unit.

    TBH, the hissing is very faint, but I'm the kinda person who likes things crystal

    May just fork out for decent wire shouldn't be no more than around £10 right....?

    Dunno if it would make much difference, bad cables can let in alot of interferance.

    To the op. Have you got any other cables to try?
    Another thing would be to move all other electronic devices away from it. When my wireless phone is near my hi-fi it makes a buzzing noise.

    Spot on, and make sure the speakers are not too close to the tv itself.
    Have you got any wifi stuff near the speakers, wii or similar ?

    Have you tried turning the volume down on the hi-fi and up on the TV?
    Sometimes if the speaker volume is high, it will produce a hiss.

    Nope, just the one.

    Its very very faint, it isnt like the buzzing of a mobile, kinda the sound of speakers when turned to max volume with no output.

    Except this happens when at average volume. Its not a serious thing, just me being picky, wanting it silent!

    The TV speakers are on mute, the hifi speakers are at an average level. EG, when the PS3 is loading a game and its silent, I can hear the hissing.

    Unfortunately, the speakers are on either side of the LCD, and have to stay there due to having no room. Theres a subwoofer on the floor. A Wii, PS3, and an external HD. Would that affect it?

    Cheers for responses. May give the cable a bash anyway

    I'm not sure whether LCD TV's have the same problem as CRT ones but if you put speakers too close to the tv screen on a CRT it will pull the colour from the TV towards the speaker.

    This is due to the magnets in the speakers. Some speakers have shields but not always the case.

    Anything electrical could affect the speakers.

    Yup, thats come across my mind, used to have a CRT by it, no affect on the LCD though

    Only way to see for sure whether it's the cables is to run the same speakers and cable through an amp/hifi system and see if you get the same hiss.

    Other than that get some new cable as you've said and see what happens.
