Wire an OEP A262A3E in a G7 ?

Jazzy_Pidjay · Aug 24, 2004

hi !

My G7 is on way, just capsuleless

i don't know exactly how to wire my OEP ?

i think is :

Secondary S1 -> 2µ2
Secondary F1 to the screen

Primary S1 & S2 together -> Out +
Primary F1 & F2 together -> Out -

But how to connect the Secondary S2 & F2 ??? :?

thanks !

nobody know ? :?

Hope it helps.

thanks

i know that, but i ignore
if the secondary S2-F2 play a role in the G7 ??

because the LL1538 have only 1 secondary
and the OEP have two !

I think you can use ratio 6,45:1. This ratio you have when both primary and secundary is in series. Lundahl have diferent windings.

Both windings in parallel means 6,25K:150ohm?

Jazzy_Pidjay · Aug 29, 2004

6,45:1 no ?

gyraf · Aug 29, 2004

yes, 6.25:1

impedance ratios are squared.

I like the contrast of your mike body and grill. Really nice work.

Does somebody know if there is a problem
to use the OEP A262A3E in the G7?

Was the schematic of the G7 designed only for the lundahl?

thanks

Don't know.

Try it, and let us know..

:shock:

ok, :roll:

what kind of incompability can i found ?

On the Gyraf website, i have seen a G7 in a Nt2 body with an OEP.

i'm a little anxious :?

??

I don't get that? I've never tried the OEP's for mics..?

The OEP mic input transformer 1+1:6.26+6.25 should work - but I haven't tried it.

Michael Krusch's version of this mic, based on a scrap Rode NT2 and OEP transformer:
