Did anyone ever ask Jon of JKLabs? I read that he has surfaced recently.
Remember though that Jon did not make an active cable for the 480/460 bodies he just make an active cable into his own box. Big difference.
I'm not sure this is correct, I think raoulduke has an active cable system that connects his caps to his 480 bodies, I know he does not have the same dvc preamp and cable system that I do, and that there are at least two different systems for the 480 series engineered by JK Labs
I think Tim/Raoulduke had/has the jklabs ECMS system for the Gefell caps, not the AKG caps. I had the JKLabs ECMS system for the AKG ck6x caps, which I sold to Tommy. The ECMS system -- Extended Capsule Microphone System -- is what Jon at jklabs built for an active mic system. Active only that is -- the DVC allowed active/remote caps, but the DVC was also a built in mic preamp. The ECMS system is only an active mic system, no mic preamp functions. Mine worked off 9v, but others he built were powered from the 48v phantom coming from your mic preamp.
At any rate, the ECMS had the active cables for the caps, but it used a separate box to work as the mic "bodies". As far as I know though, Jon never made a system to connect "active" AKG caps to the 480 or 460 bodies -- he just had the ECMS system or the DVC system.
the box i own is an "ecms-23" and it performs the same function as the two microphone preamps, aka bodies, that it's replacing in the gear chain. the ecms series (as well as the dvc boxes) can be used with microtech gefell m2x and akg ck6x caps if utilized with jk labs manufactured active cables and collettes. factory manufactured neumann akx>lc-3, mbho ka caps>active cables and schoeps collettes caps/cables can be used with the boxes as well, after modifying the cable terminations.
my ecms doesn't utilize a 9v battery for its powering, it needs to be supplied from a 48v phantom powered preamp (just as todd stated); my active cables plug into dual 4 pin inputs and the outputs are male xlr (the same config as the ecms-22).
there are two "non body" offerings from jon that i'm aware of:
1) dvc (direct access from cable to mic-pre)
2) no mic-pre alternatives to the dvc
2a) autonoumous 9v powered "ecms" unit with xlr or rca or other output (lee>toddr>tommy) aka the "ecms-22"
2b) p48 powered "ecms-23" with xlr outs (nic>myself)
my understanding is that each dvc box has it's own serial number based on build order, so no one person has the same number dvc, i.e dvc1, dvc2, dvc3, etc. the ecms series of boxes (ecms-22 and ecms-23) is actually the model number so theoretically more than one person could own an ecms-22 or 23. however, i
think jon only built one of each of the ecms boxes and tommy owns the only "22" and i own the only "23".
here's some pics of various jk labs set ups. mine were posted at one point but they were erased when i reset my account; my 23 is similar in appearance to the ecms-22 except that mine doesn't have a power switch.
