Background noise in floorstanders twitters

1) All but the input selected will be switched out-of-circuit.

2) An unused input is automatically out-of-circuit by virtue of having no source equipment plugged in to complete a circuit. (And still out-of circuit until the source is actually switched on.)

How can you get noise from anything that is out-of-circuit?

Hi Chebby, I think I may not have been precise enough. I was referring to an input selected but with nothing attached, which can generate noise until something is plugged it. It was my opening reply, and at that stage it was not clear what the OP was actually listening to. My experience is that users sometimes click through their inputs and hear noise on one (often the phono stage in hifi amps, unsurprisingly given their massive gain and eqaulisation).

I think we can probably conclude it is residual (white) noise that is of no consequence, unless it is burbling or otherwise variable, in which case something is needing repair.

Whoosh, see those goal posts move! Of course a vinyl input will hiss when not loaded. It's not interference at all, it's the noise from the transistors or IC or whatever.

Sorry, I'm 95% sure that is wrong.

That makes me right, which I'm 95% sure is wrong! :help:

Trev, no-one mentioned interference (until you just did), but it is indeed noise.

You wrote " I guess because they are wide open to random noise from other electrical equipment".

I call that interference, so you did indeed mention it.

Thank you all guys for support. My receiver is a cheap one (250 € bought 8 years ago) and it seems that the hiss is a matter of build quality of the receiver. I am aware that the speakers deserve a better amp and for this reason I am investigating Creek 50A. Wish you all the best.

Dan, have you tried one of those cleaning disc with the di-maganatising tone on it?

Yes I know it sounds like crazy talk, but if you can find one (they're fairly cheap) try it - I actually run this tone through my set every 50hrs or so, call me crazy, superstitious or strange - but my amp is dead silent no hisss, you have to really crank up the volume before hiss becomes audible (admitedly it was always silent ref background noise but its 10 years old now and still silent ....)

Try the disc......
