The 32087 is the light grey paint / blue and black knobbed version of the 2087 ‘disc cutting’ eq.  (the ‘3’ in front of model Neve module model numbers refers to the newer colorscheme rather than the older darker paint with Marconi knobs look... therefore a 31076 is the lighter grey version of a 1076 channel input, etc.)

Comments from Geoff Tanner regarding the 2087:

“They were used on Neve Disc Mastering consoles and provided stepped (ie
highly calibrated) EQ settings on the two stereo paths through these
consoles. The module is, in effect, two 1081 motherboards but minus
the mic input transformer. They used stereo switches for all the gain
and frequency switches.

Early models switch the EQ in/out via the regular Isostat switches but
later versions have a relay card (I think a BA251 from memory) to do
the task using one of those expensive Teledyne relays that resembled
an early 8 pin op amp.

The last one of these I employed whilst at Neve was for a custom
monitor console for CBS Records at Aylesbury. They pressed vinyl
albums there and used the huge "pancakes" to load the 1/8" tape,
already pre-recorded in both directions, into the automatic cassette
loading machines. (This was years before CD's really took off)

The console was to check the quality of the incoming tapes from the
studio and to compare them with samples of manufactured product.

They used to tweek EQ at times, and used the 2087 for this purpose.

I bet that thought scares a few folk but I was told the quality of the
masters was such that they would not transfer well... or some such
thought!”

And in another post:

“Oh Lord! This is the module that most studios engineers would die for!
(Well, I thought they were good but what a @#$% to make!!!). The module
is 12" high and a double module width and is, in effect, two 1081
equalisers with ganged stereo controls. Even the boost /cut controls were
gold plated Elma switches and the module had a line input section only.
It was used for mastering purposes and not many were made. . . I believe
less than 20 because I sold two of them and the others were used in Disk
Mastering Consoles.”


Features of the 2087/32087:

Lo Freq – switchable peaking or shelving response:  33, 56, 100. 180, 330 Hz

Lo-Mid Freq – peaking response with hi/lo Q switch:  220. 270, 330, 390, 470, 560, 820,1000, 1200

Hi Freq- switchable peaking or shelving response:  3.3, 4.7, 6.8, 10, 15 kHz

Lo pass filter:  3.9, 6.6, 8.2, 12 kHz

Hi pass filter:  270, 150, 82, 47, 27 Hz

Gain control- plus or minus 12 db

EQ and phase in/out

NO MIC PRES! Line input only

Basically line-level pair of 1081’s with a single set of controls for both signal paths and all controls on rotary switches.

Some pics (the only ones I have).








Those are all the pics I've got.  Somewhere I thought I had a nice picture of a 2087, which is the classic Neve look and was a gorgeous, detailed picture, but I guess I didn't save it, 'cause I can't find it anywhere.

So.... do you have the opportunity to acquire one of these?  Sounds like quite a find.

Peace,

JC
