Le LA502 est un compresseur électro-optique, "Soft knee", basé sur le design des LA2A/LA3A que nous avons adapté au format Séries '500'.
Il offre la compression "vintage" et chaude de son ancêtre grâce à sa réponse optique, sa "side chain" et ses transformateurs.
Il se distingue particulièrement sur les voix, la basse et la batterie.
Le LA502 ajoute quelques options à l'original telles qu'un nouveau ratio de 6, deux filtres passe-haut et deux attaques plus lentes de 10 et 20 mS.
Il vous suffit de l'installer dans votre rack LunchboxTM compatible API* pour commencer à travailler.
1: PEAK Détermine le niveau de compression, de 0 à 40dB de réduction de gain. Il agit sur le seuil de déclenchement de la compression.
2: RATIO Commutateur à 3 positions qui determine le ratio.
3: HPF Ce commutateur insère un filtre passe-haut dans la "side chain". Permet d'obtenir un gros son et évite les effets de pompage au rythme des basses.
4: ATTK Détermine le temps d'attaque du compresseur.
5: BYP
6: GAIN Ce potentiomètre règle le niveau de sortie du compresseur.
7: Vu-mètre Affiche la réduction de gain de -3dB à -20dB.
Absolument tout!
Vous apportez la soudure (choisir une soudure de bonne qualité, diamètre 1mm max) et la Lunchbox.
Le kit du LA502 est d'un niveau facile. Il peut être réalisé par toute personne capable de faire une soudure propre.
Les réglages sont simples. Ils nécessitent un voltmètre alternatif correct.

The LA502 is my first, but definitely not my last Sound Skulptor module. The kit is very well sorted and the instructions are excellent. There are numerous Youtube videos in which Sound Skulptor modules are assembled. If you prepare yourself, you will also learn some tricks on how to solder better.
I took my time with the assembly and worked carefully. As a result, everything worked right away.
And the sound of the compressor? Fantastic! I love it on vocal tracks.
Many thanks to the Sound Skulptor team
These compressors were a very easy build, with fewer components than other Sound Skulptor kits.
This is a nice payoff, because you get a phenomenal sound for quite a small effort.
VERY glad I purchased. They are installed next to my CP4500, and my two CP554s.
I bought this unit already assembled on Reverb. This a very musical sounding comp. I use it mainly on Bass but it works great on all kind of sources. You can dial in a quite heavy compression without it being too obvious. It does not color too much. This is a professional Hi End compressor. I like it a lot!
The extra functions in sidechaind are very useful. Premium quality in all components and the great sound reminds me a lot of the LA3A.
For the record, I had never soldered before I bought my first Sound Skulptor kit (CP5176). I have had this compressor for a few months now, and I am in love with what it does to vocals and bass. I use it on everything though... [insert shrugging emoticon]. Tuning the LED's was a little tedious and time consuming, but everything else about the build was easy. Highly recommend if you want some creamy vocals and thick punch bass!

Perfect Introduction to DIY 500 Series Gear
For starters, I don't know that I'd recommend this as your *very first* soldering project. It is not a difficult build at all, but personally I'm glad I tried my hand at something even simpler (like a Fuzz Face-style pedal) first to "iron" out the kinks in my soldering technique. My first pedal build did have some issues, which were not hard to trace out and fix in that tiny circuit.. This circuit is nothing crazy but it is definitely more complex than a Fuzz Face! Just food for thought.
That said, I don't have a ton of experience beyond a handful of pedal builds and a whole lot of cable assembly, and it went very smoothly, testing out as expected on first power up. All in all, the build was finished and tested about a day and a half after the parts arrived, probably ~5-6 hours total, moving at a leisurely pace. Also it arrived lightning fast, being on a different continent (US) I didn't assume I'd have the parts within a week of ordering, let alone have the whole thing built, but sure enough it arrived only five days after ordering, mad props to Sound Skulptor for that.
Lastly and most importantly, the quality - this thing sounds phenomenal. Optos are my favorite style of compressor and I'll admit I was highly skeptical $300 would build me anything all that special, but I was wrong. Almost bummed I have no need for all those LA-2A plugins I've got now... This is all I'll need, at least until I find a good tube-based opto build to add to the collection! Even then, I have no doubt this will be getting used heavily for a very, very long time. Especially love it on a bass track, no surprise there as that's always been one of my favorite uses for an opto. I also have no doubt that I will be ordering many more kits from Sound Skulptor, if their other units live up to this experience then I can't imagine there being a better value on the market.
