Neumann V422

Neumann V422

Looks like there's no mention of this device at GS.

It's from 80s, manual describes it as "isolation amplifier", it looks as preamp /splitter combo.
There is mic/line option and 48V phantom - therefore it acts as preamp.

The trick is - there is no gain pot. Any ideas and opinions, could it be used as typical preamp without or with modification? Sort of "fixed gain" preamp wouldn't make much sense for microphones, but it might work for line level signals, I guess.

was it a typo? I only know the Neumann V 442, which was the splitter everybody used on live sound installations and in recording studios with multiple control rooms, back in the 80ie and 90ies. I remember Galaxy studios in Belgium had like 32 channels of those in 1995.
Neumann site dates it to 1982:

I own one of those and did a love album of a singer songwriter with that. Only guitar and vocal and room mics. Sounded great. Level control before the converters was done with an Api Lunchbox with compressor modules from different brands (I remember only 2 Pendulum OCL500, which were excellent for that task).
There are at least 2 revisions of that Neumann splitter, one had phantom always on on eyery channel switched to mic input, and one had separate switches on each channel.
I once read in an interview with some bigger named tracking engineer, that he loves that thing as a DI for Rhodes. I never tried it though.

Yes it was a typo - thanks for correcting me! Its V442 of course.
I was sleepy while posting last night..

So - how did you control gain level while recording vocal and guitar mics?

I have one. I don't use it a lot, but when I do I love it's sound. Mine's aplifies like 6 db, which combined with Neumann 7x mics gives enough level for some aplications. Sometimes I think to sell it as I already have other neumann line splitter cards in use and enough preamps, but when I take the dust of it and turn it on I always smile.
Heck I just get the idea to use it now

so again, mine gives around 35 dB of input gain on its mic setting. Then signal goes to Pendulum OCL500, which can easily take hot signals, as well as provide clean boost for too soft signals. Makeupgain/Output of the OCL controls the absolute overall level before a/d conversion. I don't actually use much of the threshold/ratio controls to dial in compression - just catching some peaks, if at all...
If the mics are the right ones, this works just perfect. If not - just go for a real decent preamp, linke with input gain, impendance, outputgain, phase, phantom and lowcut switches...

35db? That would be great... Is a setting inside or was it modded?

my one was not modded, afaik.
I actually never measured the exact amplification value, but just compared to another pre and its setting for seeing a similar output on the meters...
most probably there were different versions around. or yours is broken, wich would be sad. try to ask Neumann. They are stll around as we know. ;-)

So there is amplification somewhere between 6 and 35dB but definitely there is amplification.
Thank you both for that cool bit of info!

Yes, there were several models, I think I spotted at least 2.

Oh btw - that would be amplification measured in mic mode, but there is line mode too, with less amplification I guess?

Ok, I tested mine: 18db of amplification or 0db. It's the "A" version. Sounds really nice.

As far as memory serves, most Neuman fixed gain mic amps were set at 34db and designed to be used with condenser mics.

Ribbons and low-output dynamics might do alright with a Cloudlifter, ya think?

you're right, thats the case with V472 and V475, but V442 is a splitter, not an amp... it amplifies and it's a Neumann, so it sounds very good

so its transformers must provide passive gain, meaning that different taps on the transformer could provide different levels of gain.

you can download the manual here: https://www.neumann.com/?lang=en&id=...ct_accessories

In short: there are a few versions. One of them, V442 A version 3.2, amplifies 18db or 0db. I was suspecting something was wrong with mine because I had +48V always (provided it's on, of course) both in Mic and Line modes. Now it's clear: mine is the 3.2 version, and thanks to this thread I've found a place for it in my studio
