jumper leads- where from?

I need some budget jumper leads to convert biwire speakers to single wire.

Does anyone sell them or should I make some up myself?

 

Take a couple of of samples of 30amp twin and earth from your local DIY store, strip the red and black conduits out, cut in half and away you go.

 

Alternatively RA sell pre-made jumper leads. Or just buy a couple of extra inches of speaker cable and use that.

 

somtimes I use paper clips, works great, or a rivet thats popped.

 

There's a simpler and much more cost effective solution.

If you can unscrew the whole binding post plate you'll probably find that the inside face has four bolt threads sticking out. The fly leads from the crossover often use an eyelet loop and are attached to these bolts and secured with a small nut. It's a really simple matter of moving the HF flyleads down to the LF bolts. You now have speakers converted to single wire.

The whole process takes about 5 minutes max per speaker. It is totally reversable, and you won't need to be worried if jumper cables are affecting the sound since you aren't using them. Infact, you are not introducing anything new into the audio chain at all.

Cost = £0 (unless you have to buy a screwdriver )

good.

okay here's another question.

I need an interconnect from a TV to an amp than will run round a fireplace hearth. I want it to be as inconspicuous as possible so something pretty thin and white would be good. Any ideas for cable choice? I can solder the plugs on myself.

What about using some thin QED speaker cable? Is that possible?

Quality isn't that important. Cheap is.

 

Bell wire is unscreened. It could act like an aerial and pick up interference, though you might be lucky and get away with it.

I got some thin 4 core screened cable from Maplins. It was a bit like PA18U which is just 5mm thick and has a grey sheath. 69p per mtr or £20 for a 50 mtr roll. Worked well.

perfect

 

how do you connect it to a phono plug?


I've only ever soldered cable with two wires before.

 

First off, you'll only use two of the 4 available cores. The other two are surplus to your needs, so just cut them back.

The soldering process is similar to other cables. The difference is the way the cable is constructed. There is a central copper conductor for signal surrounded by a rubber insultator, then that is surrounded by a jacket of braided copper wire to provide the earth/screen which is in turn surrounded by a rubber insulator. For this particular cable you have four of the individual cables bundled inside a PVC outer jacket.

Simply take one of the four cables and peel back the outer insulation to expose the braided copper. Peel it back and twist it into a tail. This is what you solder to the longer connector inside a phono plug. Carefully cut away the insulation around the inner core. This is what you connect to the shorter central pin of the phono plug. Repeat for the other phono plugs.
