with a +/- 18V supply and a 2K load,
it should do about 11Vrms out
at unity gain, noise is 124 dB down
with 20 dB gain, max 1.1 Vrms in, -121 dB
with 40 dB gain, max 110 mVrms in, -110 dB
with 60 dB gain, max 11 mVrms in, -98 dB
none too shabby :-)

(in practise, you'll set your 0dB ref level somewhat below the
11Vrms obtainable, so real life numbers will be somewhat worse)

Our memories obviously differ. Certainly as far as the UK is concerned,
VUs
were standard in recording studios in the hey day of multitrack tape. When
I was at Neve, 99% of all our consoles were fitted with VUs. The only
exceptions I remember were the BBC and Pete Townshend. We might fit a bar
graph meter on a stereo out but that was about it.

Just had an e-mail from a pal in the UK who states that Pete Townsend had a
Trident desk. I wonder, was that before, after, or as well as the Neve?

I wonder what Neve's market share is these days? Studer and Lawo
seem ubiquitous and both have a very solid reputation.

Never seen any of either. I'd never even heard of Lawo until your post. Where do
you come across these ?

The Neve in Decca studio II was fitted with Decca type PPMs, to bring
compatibility with the other consoles. The API had VUs, with the kind of
meterbridge I mentioned. Both the old and the new consoles in studio
III had PPMs,as did all cutting and dubbing rooms, so I suppose we
were luckier than most. These meters had Ernest Turner and Sifam
movements and Decca built driver amps designed by Alan Reeve.


Iain

Decca were probably the other notable exception, especially the classical
recording side.

Probably after. Pete already had a Neve at Eel Pie when I went down there
(probably 1975) - he just wanted an extension to add some more input
channels. That same year we replaced the Helios in The Who's Rampart Studio
with a custom Neve (designed by me) with real Rose wood end cheeks, real
leather buffer and luminous silk screen printing on all modules. I remember
going to Trident's launch of the A series about that time so it would most
likely be after. Rampart was sold ISTR and I don't know if Pete still has
Eel Pie or not.

That idiot web ref is totally wrong !

Here's another one for you then .....
http://ccrma.stanford.edu/~jos/mdft/DB_SPL.html

Human breathing (at 3m) 10dB

I know this much. When I took those 30dB readings outisde the local venue it was
quite clear that breathing wasn't registering as a significant component of the
noise.

You are quite quite wrong about this or you must have some serious nasal defect.

of course this aspergers syndrome afflicted cretin has at least one
serious nasal defect , it is the one through which what was left of
his brain has been leaking away since he was sent down from Sydney Uni
having been caught fellating a lecturer in the orchestra pit in an
attempt to secure a passing grade. Any dialogue with this seriously
developmentally delayed life(?) form is an abject waste of your time

Type the names in Google, and you will come up with some
links to die-for audio consoles.

The Lawo MC2-90 was used by YLE (Finnish Broadcasting) this year
fotr Eurovision. It attracted a lot of attention from technical visitors,
particularly the BBC I am told.

AFAIR Eel Pie Studios was not on the island but I think you could see the
island from it - - it was 30 years ago so the memory is suspect ;-)

No. I don't think the studios were on the island, or they would have
probably been called "Eel Pie Island Studios" which would have
been miselading as there were studios under the name of "Island"
in an old warehouse in Camden. When Island records took
over the premises, they inherited a cat. which became a favourite
with everyone during the restoration and fitting out of the building.
When recording started, the cat used to wander into the control
room and sit on the console overbridge dead centre facing the monitors.
He became known as Maurice Dolby, and many people considered
him some sort of a talisman, a lucky charm, like Catweazle's frog,
Touchwood, and specifically asked for him to be present on their
sessions.

Halcyon days:-))
