Neve 2254? Or 32264? And "a" or "x'?
mg...@earthlink.net
if it's the 32264, what's the diff between an "x" and an "a'?
Feel free to email.

a 33609. And the 2254 is a studio peice and sounds great also. They both have
different uses. Mark

Hi,
there are some Neve inboard compressors models people love.
The 2254s, with 2254,2254a,2254d,2254e, these are the square ones with the
simpson meter. These are Class A compressors.
And there are the 32264s, which are mostly found as 2264 (with other frontpanel
color), 2264x and 32264a.These were is the later consoles, like 8068 and 8078.
I don't really know whats the different in the "x" version, but afaik the "a"
is the version with 2 automatic release times. We have 32264a in our studio
and it has 2 auto release times, labeled a1 and a2.
Hope somebody could clear the "x" thing, because that interests me also.
best regards from germany,

8068 I think. The 32264a is from a 8078. There is also a 2264 without
the "x". They all sound good. To me these are probably the best all
around compressors(probably a Distressor also). I own (2)2264's an
(2)32264a's and a stereo 33609(with the metallic knobs). If someone
stole all my other units and left me with these only, I could still do
some slammin mixes.

I would be happy to steal all of your other compressors if it would
help you prove your point. Just let me know if I can be of service.

Hi
Ummmmm, I don't think so!
Any Neve module with an "x" suffix, from my recollection, implies that
it was manufactured to a really wierd USA spec that insisted on the
ability to drive 150 ohms instead of the usual 600 ohms. This
especially applied to console's built for CBS TV studios. The 2264x
came out of that beastie and the problem is that the turns ratio of
the output transformer is much lower than the regular 8dB step up
normally fitted in these modules (an LO1173 transformer, as used in
the 2264, 3405, 3104,etc.)
I believe that the transformer concerned has only a 2.5dB step up
which is, in itself, interesting, because that's the same turns ratio
as the output transformers in a 54 series suitcase console (that can't
hit +26dBu as a consequence).
I have seen some God awful attempts by famous Neve fixers to adapt
consoles fitted with this output transformer configuration to a
regular recording studio configuration... with the result that the
headroom came crashing down due to the amps being gain boosted up to
raise the insert levels from -10dBu into 150 ohms to +4dBu into 600
(and above) ohms. Typical headroom, as a result, was around 11dB due
to these and other associated factors.... instead of the "normal" Neve
headroom of greater than 26dB.
The "proper" fix was to completely restructure the gain structure of
the console, either replacing the +2.5dB output transformer with a
TO129 +8dB version (as fitted to 3415, 3114, etc) or our TF1's to
provide class A, especialy in the mix outputs.
The 2264x may have a de-eeser (which is just an RC network in the side
chain to squish harder as the frequency rises) but I can't remember
because only a few were built. The important thing to remember is that
any module with an X (eg 3415x) is fitted with an output stage adapted
to to drive 150 ohms and that some work is needed to maintain Neve
specifications into higher impedance loads.
Also, don't forget that any of the later Neve modules fitted with the
TO129 transformer (33415, 31105, 33114, etc) MUST drive a load of 600
ohms unless you want a lovely hump in the HF response and ringing like
a bell on your square waves... sibilent city! You would be amazed at
how many racks, lunch boxes, etc., I see that are missing this vital
little 2c resistor!

Interesting stuff. Care to elaborate for the electronically challenged?
- Does "across the o/p transformers" mean across the balanced output of a
3415 (pins 13 and 14 on the rear connector)?
- Where do you phisically put the resistor?
- How does a patchbay and the selection of gear influence the value of the
resistor?
- What do you use so many 3415's for? Aren't they primarily summing amps?
How many busses do you have there?

Hi Predag
That Neve of yours, unless modified by a loony, should have the 600 ohm
resistors already fitted. The exact placement varied, depending on whether a
fixed patch bay was used. If so, they were often fitted in pairs of 1200
ohms, one on the break contacts of the listen jack and another on the main
signal input. Thus, if an insertion were made at this point, the module
would still see 1200 ohms.
The 3415's frequently had a 620 ohm resistor wired directly across the
balanced output, either at the module connector or at the XLR.
You can generally find the resistor with a little hunting, or, with the
module lifted out, you could measure the impedance across the two output
pins (13 and 14) on the module connector to check that it's around 600 to
1200 ohms.
The console Blake is referring to is the mother of all Neve consoles....

used as power rail decoupling on many neve IC-5534 based amps. My problem is
that on two areas of the BA683 motherboard (off a 5402 8ch suitcase console)
the output amp for monitor right and aux 2 summing amp have had their 10ohm
and 68ohm resistors (respectively) burnt out upon powering the board up. In
both cases these resistors connect the rail (+ or -15V) to the chip and the
aforementioned tantalum cap is connects this point to ground. All values are
10u/25V, blue, and I think they may be made by Phillips.
(Even with the IC taken out and the resistor replaced, the resistors still
burnt).
If anyone can cast any light on this problem or at least tell my i'm barking
up the wrong tree, i'd be grateful! Mark

Those are safety resistors that prevent the whole thing from burning up
when the tantalum caps go. Measure the tantalums with a meter and you will
find that they are dead shorts. This is the standard failure mode for those
things, and they go all the time.

Check it with the meter. Set it to beep-for-continuity and place it across
the caps. You'll find they are bad, with plenty of others on their way soon.
