Found this on DAT heads digest...
" ...a JKLabs ECMS box and
active cables for use with AKG CK6* series caps (MG active cables are also
available).
THis is like a reutelhuber, bill box, or a vms52 for use with expensive
schoeps capsules and active cables, but utilizes relatively cheap AKG CK6*
series capsules renders them similar to Collette type buds.
The ECMS box replaces the bodies of the AKG 460/480 mic series. It is the
mic amp. No other pre-amp is necessary to run the mic caps (no clumsy mic
bodies in between the cables and another expensive pre-amp. THis is a true
condenser stealth rig, perfect for unobtrusive recording, or even from the
taper's section.
This is no home brew box, it was carefully designed to improve the
efficiency of AKG caps and to exploit them to their fullest potential ( in
some peoples opinion, beyond what the AKG bodies can provide).
Any capsule that is usable with akg 460/480 series mic bodies (including
omni, card, hyper and shotgun caps) can be used with this system and the
active cables and heads provided.
Available:
1 JKLabs Custom ECMS box, feat. Adjustable Gain, two Bass Rolloff settings,
15+++hrs of uninterrupted operation on 2 9v internal batts... "
Anyone heard of this one? I'm finding it hard going getting any DIY info or schematics on this sort of gear. (Jealously-guarded secrets?!)
