Crossover networks 101
John,
thanks for the hopeful note on the 2461s. I have always found them to sound pretty good in the slant monitors that they are in, albiet with quite a bit of graphic EQ help.
(Zilch, Thanks again for pointing out the link for the network schematics.)
I have been going over the schematic for the 3133 network used in the 4333 monitors. It all seems pretty straight forward. However, there were a few questions.
a) In the band pass section there is an inductor that is tapped in the middle. The three leads are labeled Rd, Grn, and Blk, so if I can buy an inductor that is tapped and has the leads color coded I be in great shape. However, looking in the PartsExpress catalog I don't see anything like that. Should I be able to find something like that? Can I tap it myself?
b) The values for the inductors are taken to the 100th of a micro farrad in some cases. In many cases there are not equivalent value inductors in the PartsX catalog. How much tolerance is there for these values and/or where can I find inductors with these values?
c) I understand that coils are often mounted on network boards in alignments that prevent them coupling and interfering with one another. What are the rules of thumb there?
d) Finally, the adjustable L-pads are labeled 1,2,3, and blk, wht, red on the schematic. I want to use an attenuator out of a trashed VOTT network for the mids and buy one for the highs. I am assuming that 1=gnd and that 2 and three should be interchangable. ?? Is that right?
Thanks to anyone willing to wade through all my questions,:blah:
