Melded piezo array switching - Full/Half/Off
Re: Melded piezo array switching - Full/Half/Off
Harley, as you've got it, there are four 'sets' of four piezos, obviously for a full array of 16 for a jack 12 or similar. I'm doing an array of 8 melded, with the DPDT switching. So is it wired simply as four 'sets' of two piezos? Sorry if its a dumb question, just a newb with the wiring!
Cheers, Tim.

Re: Melded piezo array switching - Full/Half/Off
J112 has 16 total tweets, so 2 sets of 8 opposed tweets. If you have 8 total tweets, that's 2 sets of 4 so from my diagramme above, take 4 opposed tweets out of each section - thus;Fenderfan wrote:Harley, as you've got it, there are four 'sets' of four piezos, obviously for a full array of 16 for a jack 12 or similar.

..that's if you want full/half/off switching, which I wouldn't personally bother with when I just have 8 tweets. With 8, for me it would be full on or off

I so stole those. Thanks mate.
If it's too loud, you're even older than me! Like me.

I assume this would work just fine for OTops too? Thanks, Harley!! OTOH, now I've got MORE parts to buy for the OTops I'm building.

Re: Melded piezo array switching - Full/Half/Off
For Otops, ( 12 tweets in total for OT112 ) I personally wouldn't wother with a 1/2-full-off switch as these are tops as distinct to Jacks, which are mainly an elect bass or keyboard cab.miked wrote:I assume this would work just fine for OTops too?

However, if you'd like the luxury of the 1/2-full-off switching, then knock your socks off - it's simple enough to wire.
Re: Melded piezo array switching - Full/Half/Off
Thanks for the input, Harley. I'm just building my first set of OTops, whereas you've built about 528 of them, give or take 1 or 2. So, I'm going to defer to your experience. If I find them too bright, that's what EQ is for.

Awesome, that's what I thought. Cheers Harley, and thanks for the secondary diagram too!!

Re: Melded piezo array switching - Full/Half/Off
Having a little trouble wrapping my head around this -- for example, why does the positive lead only need to be wired to the center?
What I would like is for the switch to be wired so that the middle is half, while the outside positions are off and full. Is this possible or does OFF have to be in the center?
Thanks

Re: Melded piezo array switching - Full/Half/Off
It just so happens to be that, that is the way the switch is physically configured. Take an outside terminal and feed it to your middle tweets, and use the other terminal for the top and bottom tweets. There would have to be a wire that ran from the top sets, down past the middle sets (but not wired to them) and wired to the bottom sets

Re: Melded piezo array switching - Full/Half/Off
I see diagrams for 8 & 16 tweeters. Can 6 be wired like this?
