Cross-over schematics for the 4660

[Jan Daugaard]

Does somebody have the schematics for the 4660 cross-over?

I'm not sure what the difference between the 4660 and the 4660A is (it could be the woofer 2225 vs 2226), and I need the schematics for a 2226 woofer and a 2425/2426 compression driver on a 2346 horn.

Thanks in advance!

Hi Giskard,

thanks very much for the schematic -- 4660A_Page_1.jpg contains just what I was looking for.

It appears that L3 has a switch with 5 positions. Do they represent 5 choices of induction between 0 mH and 3.3 mH?

And what does NC stand for?

It's a tapped autotransformer. You'd have to measure the taps if they aren't specified in the schematic.

No Connection.

It's an odd note about the 2426 impedance. Looks like they switched to the 16-Ohm "J" in the "A" version, and advised swapping out diaphragms in the originals when required....

Ooops!

Seems like they would both work unless I am missing the boat on this one.

Not like I haven't been wrong before!!!!
