I know the AI-1 cable has been covered a lot in threads. But, I could not find this.

I am in the process of buying items to construct an AI-1 cable for some 3.1TLs. I have already consructed a "regular" SDA cable for them and when I redid the crossovers, I added new binding posts and rewired the pin (of the pin/blade) wire to a new binding post I added. The blade wire is connected just as it was originally (except it is soldered now) between the blade and the negative lower binding post.

The question I have is, do you need the blade signal to utilize the AI-1? Or is the pin the only one that needs to be hooked up (like the "normal" SDA cable)? If you need the blade signal, can you hook the negative binding post from the transformer to the negative binding post on the back of the speaker (which is connected to the blade wire)? Basically, I want to know the correct way to hook up the pin/blade connections for the AI-1 on the back of the speakers. Thanks again for all of your help guys.

Yes-- when using the AI-1,, connect the "blade" to the negative bp on the speakers.The pin would go to your new "pin bp".Hope that answeres you question.:)

That is how the wires are connected now, but I am wondering about the speaker cable wires going from the transformer to the back of the speakers. If I have the pin and blade wire connections as you and I stated before, where would I hook the "positive" and "negative" speaker wire leads to? The positive (red, for example) would go from the positive binding post to the at the transformer to the pin connection at the speaker I am fairly certain. Then, the negative (black, for example) cable lead would go to where on the back of the speaker terminal? To the blade connection on the negative terminal binding post? Thanks again.

From the transformer,,one set will go to the pin and the other pair will go to the negative binding post on the speaker.

Hi George,

Thanks for the link, that's the design I am basing my AI-1 off of, so a BIG thanks to Raife. One problem I run into though is that I have jumper wires with spades on both negative binding posts on my speakers already. I am using some speaker wires with bannans to g ofrom the amp to the speakers. Is the only other option to go from the negative on the AI-1 to the blade connector on the speakers (other than using the negative binding post with spades)? Can you put 2 spades on the same binding post? I've never heard of someone doing this. I don't know what the affects would be for the sonics and signal going throught to the other negative binding post? Anyone know about this? Thanks again.

Greg

Are you referring to the internal jumper going from the blade socket to the bottom negative post?

No, sorry. I was refering to external jumpers on the outside of the binding posts. Hopefully I haven't made it totaly confusing.:o

I am looking for a high quality blade connector to use with the speaker cable for the AI-1. Does anyone know where to get a quality made one? I decided to use that connection rather than trying to figure how to used a bannana or spade connector on the negative binding post on the speaker. Please let me know if you know where to get a quality blade connector. That is, a single blade connector not the double blade connector. Thanks again.
