I have seen numerous comments on other websites saying that using the screws instead of solder can negatively affect sound quality because the connection is not as "complete," for lack of a more technical term. 

You can use the pole versions of the speakon connector instead with the spade connectors if you don't like the screw down versions. I find them very convenient, and they are used in Pro Audio performances all the time.

 

Does your headphone negatively affect sound quality dramatically since it isn't soldered to the amp? Exactly. As long as you have a good crimp (and you can use thicker gauge wire too), you won't notice a difference over soldering. I have my speaker mains and 2000 watts of subs running through the same connectors.

Heya,

 

Very cool thanks for that.

 

If we get verification on it and the balanced part info, I'll be happy to link this on the first post for future use to make this ultra easy.

 

Very best,

Need to verify.

Good point. Perhaps the detractors were just doing a sloppy job. Thanks for the info!

Well, there is some truth in it, but a lot of times it is meant to sell you a service they provide, or it is so minor that you would never be able to tell in a blind test. I'm not selling anything, so I have no reason to embellish the truth.

 

I prefer the convenience, and there is a bigger chance of doing a poor job soldering and having a poor connection affecting the audio than the spade terminal would.

 

I have a new convenient cable to make for myself in the next few days when the parts arrive, which I should have done a long time ago.

 

I'll take pics too to help make it more understandable.

I found a part that looks promising for making a bare bones adapter: If one plugged the stock TRS jack into one end, and connected the 4 pole end straight to the Emotiva with plain wire, would this work? This way, you wouldn't even need to chop the end off your stock cable, unless I'm mistaken about how these work. I understand that the amp would need common ground.

Speakon may not be able to be used in most scenarios, so I may have to rewrite this for XLR and MIC/XLR cables.

When you say, "verify 3-pin," what type of 3-pin connector are you talking about?

post #2288 of 3607

BTG now offers resistors built into their adapters via webstore, at.... 500Ohm!

Wonder if Mal gets a royalty or "finders fee" for this :wink_face:

I'm going to put everything together to make something that can connect to dual 3 pin or 4 pin balanced. Speakon might not be the best way to go, but I'm going to try a few things.

For any connection to a single ended amp (common ground--both black negative speaker terminals connected to ground) you can run 1 or 2 wires from the adapter to connect to the speaker negative terminal(s). Actually 1 wire might be better because it will prevent the user from frying a balanced amp with the single ended headphone to speaker adapter.

i attempted the speaker tap option I would obviously insulate the solder points and exposed wire with heat-shrink tubing as well.

This isn't necessary with full size XLR connectors because they're so roomy but I do like to put heat-shrink tubing on the center pin of 4-pin Mini XLR connectors.

I'm confused here. The Mini-X comes with 5-way binding posts not Speakon connectors so why would anyone want to use Speakon over the much more standard 4-pin XLR?

 

The eBay adapter and it's picture don't match. The picture shows a Female TRS socket not Male so I'd definitely verify with the seller what he's actually going to ship.

If your amp has dual 3-Pin XLR connectors a good solution is a y-cable with dual male 3-Pin XLRs to a single 4-Pin Female XLR adapter. 4-Pin XLR has become THE standard for connecting balanced headphones to non-portable headphone amps.

 

Since the Mini-X is single ended (both black speaker terminals are connections to ground) the best way to connect your headphones to the speaker out terminals is a simple TRS Female socket. You only need 3 wires. They do not need to be thick speaker wires because your headphone cable wires are pretty thin at between 20 and 28 gauge, I would suggest 18 or 20 gauge. Connect the TRS tip to the Left Red speaker terminal. Connect the TRS Ring (mid section) to the Right Red speaker terminal. Connect the TRS Sleeve to one of the Black speaker terminals. That's your best solution.

The appeal of speakon is that it doesn't require soldering to connect the wires. However, you make a good point about the image not matching.

Connect the TRS Ring (mid section) to the Right Red speaker terminal. Connect the TRS Sleeve to one of the Black speaker terminals. That's your best solution.

This is just for the Mini-X though. It would do damage if someone did this with the Lepai or everything else without a shared ground.

 

While Speakon is not standard, it is so much nicer, quicker, and easier to work with than soldering to XLR. If noise becomes an issue with speaker cable (it shouldn't), one can always switch to XLR and a shielded cabled easily. Most people would not see a difference, and a screw on Speakon to 4 banana plugs won't kill anyone's amp/headphone. Having another speakon on the headphone side of the cable allows quick interlocking connections between multiple end types.

 

This also allows anyone who can't solder to create a safe DIY cable on their own for cheap.
