MP512


The MP 5.12 is based on one discrete Op-Amp, one Cinemag input transformer and one Cinemag output transformer.

It delivers what is called the "LA" sound, popularised by the famous American consoles of the 70's : the punchy midrange and tight bass tone of the iron. This MP 5.12 is great on drums, electric instruments and generally all close miked sources.

Just install it in your API* compatible LunchboxTM rack and start recording.

Highlights

  • Discrete Op-Amp (DOA) pinout compatible with the API* 2520
  • Original Cinemag (Reichenbach) transformers on input and output
  • 70 dB of gain
  • Dual track gain potentiometer for precise gain setting, even in high gains
  • Variable output pad for those who like to drive it hot
  • Fet DI input, relay switched, the signal passes through the input transformer
  • Signal/Clip LED monitors signal with full wave rectifier
  • All low level signals switched by relays
  • Golden contacts on relays and switches
  • Nicely damped quality conductive plastic potentiometer
  • 1% metal film resistors
  • High grade 105°C low ESR electrolytic capacitors
  • High grade double sided PCB with plated holes
  • Available assembled or as a full kit (everything included)

What's in the kit?

Absolutely everything!

  • Passive components (resistors, capacitors),
  • 2 Cinemag transformers
  • Active components (diodes, transistors, LED, ...),
  • Front panel elements (switches, potentiometers, knobs),
  • Connectors, relay,
  • PCB's,
  • Front panel and side panel,
  • All hardware

You bring the solder (use good quality solder, 1mm diameter max) and the Lunchbox.

Difficulty level

The MP512 kit is an easy build. The DOA is a little more difficult because of the components density.

Product Options

XT500 Extender: The XT500 option is a cable extension that allows you to test and setup the module outside the lunchbox while connected.

501 Case: The 501 case option is a standalone, single slot lunchbox with PSU.
The XT500 Extender is not needed with the 501.

Assembled Product: If you prefer not to DIY, choose an Assembled product. It comes fully assembled, ready to use.

What an awesome piece!

Audiolover - 22/01/2022

Simply WOW! super sound in all settings. If you pull the gain very high (and with PAD against it) increases the saturation but also the noise. Cleverly used an absolute universal classic at a bargain price. The construction is also no problem for anyone who knows circuit boards and soldering irons.

parfait pour les sons percussifs !

Clergeot Michael - 30/06/2021

C'est un vrai bonheur sur la caisse clair, la grosse caisse et les toms ! J'aime l'utiliser sur la basse et guitare metal, tout ce qui est assez percussif, il répond parfaitement.

Ce qu'il me fallait!

jeff buet - 11/09/2019

Je chrechai un preamp style API512 mais le prix etait prohibitif donc je me suis dis que je pourrai essayer le diy de chez Soudskulptor,et j'y suis arrivé.Pas forcement evident de commencer le diy audio electronique en commençant par un preampli mais avec le explication et le kit pas de soucis,ça a marché.Et je vais continuer avec un autre preamp et les compresseurs et eq après,ça y est j'ai le virus! Merci a Soundskulptor pour ses kits géniaux!

Amazing API sound

Hanappe - 13/04/2018

I bought a couple of these MP512 some months ago. I use them for snare top/bottom. Simply amazing. The pad function is excellent to push the pre and "compress" with saturation. I'll buy more for sure.
