I'll be ordering a 6XS soon and I had a few quick questions about the frequency modules.
I called Audio Control and they wanted $18 for each module shipped. It quickly adds up because I am going to need 4 custom modules. Now I know the 6XS comes with 5 preset modules already. Can I remove the resistors from the 4 I don't want and reconfigure those? Can they be desoldered?
The manual says you can make your own, but they really don't elaborate on it and a Google search turned up nothing.
Thanks.

hi, page 11 of the manual on audio control's website shows the formula for determining the values of the resistors ... 7200 divided by the frequency equals the resistance value in kiloohms. you could look into resistor networks (CTS and Bourns available from Digi-Key). or if you need more custom values,1% resistors and dip headers to make your own. hope this helps, mark

Yeah, I saw that in the manual. I appreciate the reply though.
I was looking for something along the lines of this...

Nice little write-up on the modules and replacing them.

Hmm.
I'm not good enough to do it myself... the modules are *really* small... you'd need to be quite good at soldering...
I don't think you'd regret paying for the custom values.. I mean.. I use an EQX to actively run my front stage and it is the most amazing thing I've ever done... I know I'll never use passives again...
Anyway though, I think you'd spend more than the $72 in terms of a proper soldering iron (i'm thinking the cheap ones really aren't going to be very applicable here..), not mention resistors and the actual work in terms of putting these things together... unless you'd value the experience (which, I mean, I would..) or plan on using that stuff again, you really might be better off just buying them..

I've got the tools and experience to be able to desolder/solder my own modules. But that link I posted above actually shows the guy using solderless Turned Pin IC Sockets (0.3in 16 pin). Pretty cool stuff and I am trying to track down someone who sells them in the US.
With the turned pin IC sockets you should only be out a couple bucks for each module including the resistors. The coolest part about them is they are swappable by just popping out the resistors and sticking new ones in it.

Maybe I shoulda read it more careful like eh?
heh keep this thread active man, lemmie know if you find what your looking for, I'd *love* to know where I can get that stuff w/o needing to solder it .. ------------- "I'm finished!" - Daniel Plainview

hi, check Digi-Key part numbers ED3316, ED56163,A402AE, or AE7303. they should be what you are looking for. i'm lazy and using a catalog for the part numbers. and of course you can resistors there also. m

Thanks Ween! I ordered one of each so I'll post up when I figure out which one is an exact match.

Got an update... one of the sockets was a perfect fit. Not bad for $1 each, gold plated too.
Okay, here are the part numbers from DigiKey:
IC SOCKET 14 PIN .300 GOLD (18dB) Part #ED56143-ND
IC SOCKET 16 PIN .300 GOLD (24dB) Part #ED56163-ND
Go to page 1157 of their online catalog for the resistors. You want the ones at the very top of the page and they are about .10 cents each.
Yageo 1% Metal Film Fixed Resistors 1/4 watt
Pick the kohm rating that you want and the part number should be something like this... 142KXBK-ND (that is a 142kohm resistor).

*EDIT: You might also want to add an extractor tool to make removing these sockets a little bit easier. Part #K157-ND ($3.64)
