Le MP599 est basé sur un ampli-op discret SK99, un transformateur Lundahl à l'entrée et un transformateur Lundahl en sortie.
Grâce aux performances exceptionnelles des transformateurs Lundahl dont le noyau est en mu-métal, le MP599 possède la chaleur des transformateurs mais il est également extrêmement transparent, ce qui lui permet de capturer toutes les sources avec une grande finesse.
Le MP599 excelle sur toutes les sources riches en transitoires, telles qu'instruments acoustiques et percussions. Il conviendra parfaitement aux application de prise de son de proximité ou distante.
Il suffit de l'installer dans votre rack LunchboxTM compatible API* pour commencer l'enregistrement.
1 Atténuateur de sortie : Ce potentiomètre atténue le signal de sortie, après le transfo de sortie.
2 LED de signal/Ecrêtage : s'allume en vert quant un signal est présent et en rouge 3 dB avant la saturation.
3 Gain: En combinaison avec le commutateur de gain, ce potentiomètre règle gain total entre 0 et +70dB.
4 Commutateur de Gain : Les positions centre et droite commandent respectivement les gains moyen et haut, tandis que la position gauche insère un atténuateur de -20dB sur l'entrée.
5 Polarité : Définit la polarité (phase) du signal de sortie. Le centre est un Mute.
6 Envoie l'alimentation fantome au microphone.
7 Entrée haute impedance (> 1 megohm) pour instruments. Le signal de l'instrument passe par les deux transformateurs.
Absolument tout!
Vous apportez la soudure (choisir une soudure de bonne qualité, diamètre 1mm max) et la Lunchbox.
L'assemblage du MP599 est facile. Le DOA est un peu plus dificile, en raison de la densité des composants.

Comme tous les kits de Sound Skulptor que j'ai réalisés, la qualité de ce kit est extra, vraiment sans défaut, solide, précis et "self-content" (pas besoin d'aller chercher des infos dans un forum pour le finir).
Une fois branché le résultat sonore est lui aussi excellent, pour une recherche de transparence en optimisant le rapport signal/bruit. Mon utilisation est de préamplifier mon son de basse. Donc mon avis ne vaut que pour cet instrument (et ce n'est que mon avis). J'ai plusieurs basses de qualité et ce préampli en extrait la quintessence. Mais aussi bon soit l'AOP discret SK99 de Sound Skulptor la sonorité de ce préampli s'est encore améliorée en remplaçant le SK99 par un ROGUE-5 (j'ai aussi essayé d'autres AOP discrets), au point d'en faire mon favori en comparaison de ceux des préamplis haut de gamme du marché que j'ai acquis et essayés (Shadow Hills Mono Gamma, LaChapell 583e, Neve Portico 511, Neve 517, Alternate Sounding MP2, Bolling Design Rafal, Phoenix Audio DRS-1R, Stam 312-5T, A-Designs P1, Sonic Farm Silkworm, Hairball Bronze et pour la marque Sound Skulptor MP566 et DI503J). Bien sur les fans de crunch à la basse pourront préférer un autre de ceux-ci, en particulier les modèles à tube ou le DRS-1R. Et bien sur chacun des préamplis nommés ci-dessus sont bien plus qualitatifs que tous les préamplis des têtes de basse (qui cependant peuvent souvent "suffire"). Mais en son clair pour faire ressortir le growl d'une bonne Precision sans ajouter de crunch ou le cachet d'un autre modèle, le MP599/Rogue-5 excelle (le Sonic Farm Silkworm s'en approche toutefois). J'ai un petit faible aussi pour le A-Designs P1 afin de faire ressortir la qualité du medium-aigu du son d'une contrebasse.
Am not a professional sound engineer, I have a few 500 series preamps for my hobby recording like Lola mic pres, DIYRE CP5, Camden500 and JLM. This is by far my favourite preamp, thanks sound Skulptor. I have my eyes on a few more. Will definitely buy more in future.
How do you evaluate a preamp? I would sort them between the two extremes of "having no sound at all" and having "a lot of sound". The MP 5.99 has not that much of an own sound. That in itself it neither good nor bad, it just tells what it CAN do versus what it can not. For example, softening a sound or pushing it to overdrive with a gradual slope into creamy, buttery overtones.. it does NOT. The MP 5.99 keeps the input sounding muscular and quick, if it's not a mic on a cottonball, see? Let's have a look at the other end of the "preamp-color-chart", a completely 'transparent' preamp, transformerless on input and output, superfast slew rate, super high bandwidth, etc. etc.: these, albeit toutet as desirable, or "true" or "hifi" or whatever lipstick you want to put on them.. are (at least in my world) close to useless without a tape machine. Why? Because they work well on signals that are already close to perfect sounding and at a good distance. Like an orchestra. Put these type of preamp on a snare close mic in a digital recording and what you get is transient hell, spiky, useless, unmusical, anemic. To make sense with such a signal in a mix needs an iron fist, a compressor, a sledgehammer and time on your hands to get all the work done that gain staging or the right preamp (or the transient-eating habits of tape) would have done for you. Me, I'm lazy. I want the signals to be recorded like they will work in the mix. Making desicions now, not later. Not fixing it in the mix. More work at mixdown? NO.
Here is where the MP 5.99 fills a gap that not many preamp makers even seem to recognize: It is clean AND it has transformers in and out. So you can use it on close-miked sources. Even on very, very loud close miked sources. This preamp can take a beating. Where most other preamps with transformers on input need a pad, (which - depending on the mic - will surprise you with a change in sound as well…) the transformer on the way in with the MP 5.99 swallows (shuffling through datasheets..) 10dBU @ 50Hz with just 1% distortion. That's practically line level, kids. You can even jumper the input transformer from 1:5 to 1:2,5 for a little less gain and more headroom. That's like "more cowbell", just better (if you don't get that, do the search engine) It doesn't stop here - another jumper on the output transformer makes it go from 1:2 to 1:1. I'm not even halfway through and there's already a few features you won't find in 99% of all the other preamps in the world. It has a pad with a potentiometer after the transformer, so you can cook the signal a little on the way in .. and turn the output down after the transformer. (insert a few four-letter words here) (or how about "Holy mackerel, Batman!!") Excuse me, if I get a little technical here, but the folks behind SoundSkulptor were thoughful enough to do an Opamp that is friendly with low input impedance. Yes, because of that it can have a low-ratio input transformer and because of that it can take levels that tear your face off. Bravo! (applause!) Thank you, SoundSkulptor! Not only can I use the MP 5.99 on super loud kick and snare without worries, but also on condenser mics with notorious high output. (which includes the usual U47.. and a few hundred others) With the benefits of transformers inbetween. To my best knowledge, there aren't even half a dozend preamps in the world who pull that off….more like, three others. But even these don't got the output-pad… or the super-duper-handy gain range switch. (biaaatch!) (just for rhyming, okay?) What does that switch do? A) low (=input pad, if your signal is broadcast-level line) B) mid (pure gold!!!) C) high (oh, that's what all the other preamps do anyway) So, why is that switch soo handy? Use it with 'mid' or 'high' and when you play it back, you can use it as kind of a mute button, switching it one down to keep the chatter from the tracking room out.
I already got a few other preamps that can do the 80-dBs-of-gain-until-you-puke without the slightest hint of noise, so putting a ribbon mic on a mouse pissing on a cotton ball and getting that up to 0dB on the A/D with +24dBU is no problem. I got a few mid-gain preamps as well (around 40-60dB) .. and I got a few tube preamps that can go from hifi-clean to a marshall full stack inbetween. I didn't have a beast like the MP 5.99.
It starts with very low gain, not with - for example - already at +30dB you find on other preamps. To sum it up: it's a tool that helps you with tasks where your usual preamps don't go. You could use it as the only preamp on an island as well, but then you would need a pretty long extension for your power strip. Soundwise, all is fine. Let me add that I am spoilt with gear, having preamps by Manley, Telefunken, JLM Audio and a few more and I have been putting up microphones since more than 30 years. Good value for the money.

Definitely worth it.
My favorite DIY preamp. Brilliant and clean sounding, one doesn't have to be professional sound engineer to note the sound quality of this preamp. I am a beginner when it comes to building DIY stuff, still managed to build it and really happy I made the decision of purchasing this
