The AKG Actives Project

The AKG Actives Project

Okay folks,

Matt (gumbino) and I have decided to take the lead on this project and get it going.  Seems like there have been countless starts that always end up sputtering out.  Not this time.

We will be taking this project in several phases (in no particular order):

- We are trying to round up all of the current users/owners of JKLabs and r/nboxes and getting a reference schematic  drawn up as a basis to work off of.
- We need to find out who would be interested in this project/product
- We need to decide on what exactly we want out of this.  Its not as easy as saying"I just want actives"
- Who is willing to pay for this type of project/product.  Not everyone is willing to spend $100/$500/$1000 or whatever the final cost would be
- Who can build this for us.  Is it Nick of Nbox fame or dp we find an outside engineer.

These are just a few of the questions we need to figure out.

If you would at all like to be involved in this project please send me a PM.  Most likely what I will do is to take the alot of this planning and development off of this board as not to clutter it up and confuse people.  When we have tangable facts and ideas then we could bring it to the board.

So if you want to help, are just interested in the project/product or whatever please send me a PM with an email addy and what you like to help with.  After a few days I'll email everyone who has responded and we'll get this thing rolling to completion.


PLEASE DO NOT POST PDF's DRAWINGS DIAGRAMS TO THIS THREAD.  EMAIL THEM TO ME AT OFOTDAKG@GMAIL.COM

perhaps we could get some feedback or assistance from Jim Williams @ Audio Upgrades as well, he seems to know the insides of the mics rather well  ???

Would anyone be willing to open up their 460/480 bodies and possibly caps and take high-res pictures? Just in case AKG won't release schematics and Jim Williams doesn't want to help? I believe there is a nice picture of the box ToddR bought from Lee somewhere. Nice to see renewed interest in this!  ;D

I don't believe Jim will work on the 480's, as everything in it is surface mount.

PM sent.

Any schematics or hires pictures may be sent to: mannr@uwaterloo.ca, or better yet, just post for all to see :)

I'll report here if I make any progress.  My first step is to build a 62V supply for polarizing the capsule.  After this, the rest should be easy :)

I've only seen pictures of the stuff he takes out, never the inside. But I believe you just have to loosen the screw at the base and slide the cover off - maybe using an xlr cable that is connected to help?

FYI, I've already initiated correspondence with AKG Europe regarding schematics on a lot of this stuff.  I think it would be best if everyone holds off bombarding them with emails / calls.   I think they'd be more likely to help out & supply this info if there aren't a ton of people bugging them all of the sudden.

I too thought about JW, but seeing that he does a TON of work on all kinds of gear, I don't know that he'll have as much time to devote to this project as we'd like.

Matt has a good point.  Let's see what happens with his initial inquiry.

FWIW, I just touched base with AKG and the tech has started looking at my caps but went home sick yesterday (hope that's not an omen!)  They told me he's good about returning messages though, so I'm sure I'll hear from him tomorrow of so (at which point I'll ask him about the CK6_ possibilities).

Can you elaborate, Chuck?

i've got photos of each side, but i don't have any software on this computer to reduce the size, i can email the high-res to someone if they want to repost the images here? FWIW they are about 1.5MB each
