Topic: Schoeps small rig

[johnw]

The magic is in the housing that screws to the capsule - that's why the housing is much longer than what you use.

The nbox is a great box, and I’ll most likely get one someday especially if I can have a variable gain control. I’m a ho that way. The difference for me with the cmr is a bit smaller foot print plus the battery life is forever............

I'm surprised no one has mentioned the schoeps cmbi bodies.  Probably a bit bigger than a CMR> CA ugly battery box setup, but a rig of mk caps>kc5> cmbi bodies> R09 would be very small.

The sound of the nbox as a preamp may be better than relying on the internal pre of the R09, but 2x cmbi bodies (~ 4" x 1.5" x 0.75") will be smaller than the nbox.  Not that any of these options is all that large in the scheme of things....

you cant use a kc5 with a cmbi according to schoeps...

Lots of information and technical knowledge going over my head here  But that's great!

Apparently the MK4s needs a lot of juice therefore the Nbox (Nbox+ better?) with its 4 9V-batteries is recommended? I see some of you mention Church-Audio's preamps, will they do the job just as good?

The Nbox supplies 60V to the capsule (same as the CMC6 body), the Sonosax supllies 48V and the Schoeps VMS021B preamp supplies 60V (I believe).

The CMRs require 9V power which is what the Church Audio preamp supplies. I would imagine that the head of the CMR (what screws onto the capsule) contains electronics which upconverts that 9V into a higher voltage, but I don't think anyone knows. It may be the need for upconversion from 9V that causes decreased sensitivity when compared to the alternatives.

I'm sure the Church Audio sounds great, but in my opinion, no the CMRs are not as good because they provide only 60% of the sensitivity from the same capsule on any other setup. It was the increased total length of the adapter+capsule and decreased sensitiviy that ultimately helped me decide to go with the Nbox.

BTW the Nbox+ is just an Nbox with upgraded (and more expensive) components. Nick can probably tell you more about the difference. There is a listening test that someone posted and the majority of people can not hear a difference between an Nbox and an Nbox+

yes, it is "locking" style.  you have to pull the lever out before it will move up/down.  the multi-pin binder for the active cable also "locks" via threads.

Thanks for the info!

Ah, I guess that explains everyone's silence on the cmbi.  Shows me to stick my nose into a schoeps thread. What's the smallest Milab rig, anyway?

Physically does Nbox+ look the same as Nbox? How long does the Nbox(+) power the Schoeps caps for? Does it go in the mic-in or line-in of a recorder?

[jerryfreak]

so if i was gonna spend the time assembling those would there be any sonic reason to buy the newer version from you first? or are they basically the same as the ones i have?

thanks again. sorry i never got around to testing them, i have a tendency to load my plate up too much sometimes

ms, are the pfas the same circuit you sent me that fits inside of an xlr body?

Essentially, although since I did yours I have moved all circuits to surface mount parts, which gives me more parts and thus better power regulation.  But it's just a regulated 9V supply plus an impedance-balanced output.  The only signal path component is one necessary capacitor.

That's just for the CMR, the circuit is different for high-impedance mics like the AT lapels and such.  For those mics, the PFA includes a buffer circuit.  That's not necessary for the CMR.

its nto that much longer. def not 'deal killer' longer

Physically they look the same, the inners are different....ie namely teflon capacitors.  The Nbox powers the schoeps for 10 hours on a fresh 4 9volts, the two pairs need to be swapped at the 5 hour mark.  It goes into the line in on any recorder.

Has anyone taken the active head apart on these cmr cables to see what's inside?

Sorry to sound stupid, I just want to know more about the nbox(+)....If I'm going line-in that means the levels are adjusted on the nbox(+)?? I thought the nbox just power the mics.
