AlexB: U73 German Mastering Comp (new ver. of older GMD)

Postby AlexB » Mon Sep 19, 2016 4:02 pm

Hello,
the U73 library released !!!

The Finished Sound
This was the main VCA compressor/limiter for disc cutting in the vinyl era and from the late 1970´s to 1990 it was used on 90% of all record in that time.

The unit has been completely refurbished and returned to the original as new conditions. This technical intervention restores the unit to the original sound and it can then rightfully be called “vintage”. It's the same sound you can listen on thousands old hit records.
The most critical, and most difficult task is to refurbish the unit without making changes to the original character and sound. This is achieved by the thoughtful choice of the right electronic components, and expert skills and experience in electronic engineering.

. High Quality programs with full dynamics and harmonic content
. Special light edition "le" programs (CPU friendly)
. Full Ratio control from 1.1:1 to 10:1
. AHEAD extended
. Internal sidechain High Pass filter
. External sidechain control
. Drive control allows to set the sound from clean to fat
. Auto Release preset
. Special AlexB skin
. No C.P. !

U73 replaces the old German Mastering Dynamics library and it can be upgraded by sending and email request. Upgrade costs 8,00EUR.

Please, check the website and download the user manual and try the Demo, it has the same audio quality and performance of the commercial release but with some restrictions.

Based on the pic the model seems to be u473a. This model was the one that replaced U73 as standad for cutting, isn't it?

I am interested on it, but I would like to know some questions

- the release doesn't have Auto position? The manual don't say about it.

- the original has 1,2,3,4,5,Lim positions for ratio, this one is 1-10, according to manual where 10 is Lim. But this 1-10 scale is the original 1-5 plus 6-9(as extrpolated ratios)? Or 1-9 is an expanded range being 9 related to the original 5? In other words: 1,2,3,4,5 are the original1,2,3,4,5 from the hardware and 6,7,8,9 are new interpolated settings?

- the hardware Bc and Ds are nor samled?

- if using it for mastering I understand this comp must be set on Lim position, is true? I mean given the fact it was used in the past as last finished direct to cutting. Or maybe it has sense to master as last step with this comp on 1-5 ratio setting? Of course anyone can use it the way he wants but I am interested about knowing the real way it was used all the years along when they used as finished for so many records, it was Limit or comp ratios as standard?

Thanks in advance

My guess is it probably would have almost always been left 'set & forget' in a limiting mode to protect the cutter head from any sudden unexpected peaks that could cause very expensive damage, but for the rest not doing anything at all during a straight 1:1 transfer of the material..

With some exceptions, vinyl mastering / cutting engineers generally worked very conservatively eg: a straight 1:1 transfer with nothing done to the audio - probably the same is mostly true today as well.

Of course everything in the chain/ signal path, even if not doing anything, emparts a sonic character due to components, circuitry, build, design etc.

So my point is, while the eq's & compressor/limiters in these N*****n cutting rigs were built to an incredibly high quality level, they would have only been used occasionally for subtle eq corrections if needed and protection, not the kind of drastic audio doctoring and 'loudness wars' level smashing we see in modern times during premastering.. My 2c on it..

Thanks a lot, RE301!

I agree about the limit choice of set&forget, maybe it was the common use for tansfers. And I agree too about 1:1 process which adds all the chain flavour.

Maybe I would use it that way, but I would like to know about the questions I posted. I hope someone who owns the library will help on this. Of course an Alex response would be perfect but I never use to see him posting apart from announcements.

There is an AUTO-Release PRESET ... is that what you're asking?

From the manual:
The U73 library includes 6 different programs:
HQ presets with 5 kernels and LE presets with 1 kernel displayed into sub-menu “U73”
U73 Comp : Compressor with variable controls and HPF on internal sidechain
U73.Comp esc : Compressor with variable controls and external sidechain
U73 Comp AR : Compressor with variable controls, auto release and HPF on internal sidechain
U73 Comp AR esc : Compressor with variable controls, auto relese and external sidechain
i7-5820k, MSI X99A Plus, 16 GIG Ram, Noctua NH-D14, Win-7 Pro [64-bit], Reaper-64

Thanks, RJHollins!

It is true, I didn´t read it clearly. That way my left question is about the 1-5 ratio positions on the real gear versus the 1-9 Alex ratio, given that 10 may be Limit one.

Apart from this any comment about original use of the hardware on the cutting tasks would be nice ;)
