Alternate Power Brick Recommendation
STRUCTURE REQUIRES EURO POWER EVEN WHEN USING AN ALTERNATE POWER BRICK. THE PURPOSE OF THE POWER BRICK IS TO ALLEVIATE THE +12V CURRENT LOAD ON THE EURO SUPPLY IF YOU HAVE A CROWDED CASE. YOU CANNOT RUN STRUCTURE WITHOUT EURO POWER. STRUCTURE NEEDS THE -12V RAIL FROM THE EURO POWER FOR THE CVBS OUTPUT.
As indicated in the "Getting Started" guide, STRUCTURE has the ability to be partially powered off of a dedicated +12V power brick that will reduce the entire positive rail current from your eurorack case. There is a barrel connection on the back of STRUCTURE, which is designed to auto-switch when +12V power is present on the jack.
Note: The Power Brick above can supply >8 amps of power, which is far more than STRUCTURE will use. If you don't anticipate using other modules that support this auxiliary +12V method, you can select a lower current version with the same connector setup.
Note: This +12V auxiliary standard is the same as certain LZX modules, like Liquid TV. LZX and ET are working on a +12V distribution module for bringing in extra +12V power on the front (or side) of a case for power hungry visual circuits. So you won't need a brick for every module, just one. Stay tuned for more details.
