Neve products..

I am writing a review and was hoping to source original manuals for specific Neve products, notably the 8252 and 8254. However, I can't find anything on the net about these products.

Are there any decent resources for old discontinued hardware products by Neve, or any of the big boys?

Those numbers aren't ringing any bells with me. Do you mean the 2252 and 2254 compressor/limiter modules?

The 2252 was very early and employed germanium transistors I think, and the 2254 was a later silicon evolution -- the classic diode bridge design.

I am going by the Acustica Audio manual.

They list the 8052 and 8054 as the units they sampled.

I'm no neve expert, but I thought the 80xx numbers referred to the 80-series consoles...

What products are you looking at? Maybe we can track them down in a different way...

Ah, sorted it. AA deciding to be obscure about model numbers. It is in fact, as you rightly pointed out, the 2252 and 2254.

This is the Acustica Gold 2 channel strip module where 8252 and 8254 buttons can be seen on the compressor (centre) section.

Number confusion!

You mean the 2252 -- which was (as far as I know) Neve's first diode-bridge compressor and employed germanium transistors in the output amplifier. I believe this design suffered from quite high levels of distortion -- always an issue with diode-bridge designs -- which, although potentially attractive in music applications, was deemed unacceptable in the broadcast industry which was Neve's biggest market at the time.

So Neve revisited the design and came up with the improved 2253 (not sure if that was germanium or silicon transistors I'm afraid) which apparently did meet with the IBA's broadcast equipment specification requirements.

Some short time later the 2254 was developed which was based on the 2253 but had additional features and more complicated side-chain circuitry I believe (so it could limit and compress).... and then the fabulous 33609 was essentially developed from the 2254 (in a number of different variations over the years).

Geoff Tanner at Aurora audio is probably your best bet for proper first-hand information.

These are 2252 compressors: Image

These are 2254s: Image

And this is a 2253! Image

Unfortunately I can't help the OP - but I know an electronics expert who can rant on about how terrible germanium transistors were. However they did contribute to the sound of 1960s rock I believe.

Ah -- thanks Wonks. I guess they're playing fast and loose with the Neve-esque numbers to avoid potential legalities...

Which means that Eddie might need to be careful in a similar way in his review.

Thanks for that Hugh. Very informative.

Do the Acustica numbers perhaps indicate a hybrid sampling of the compressors and some other Neve preamp stages? It's not unknown for them to include various options within the same plug-in rather than just do an outright 'clone'...
