Similar to the original LM-1, Luma-1 is a very complex machine. It has a dual CPU architecture (Z80 + ARM) and makes no compromises with the audio path. Luma-1 uses the original nine individual DAC chips, and the original “loose” clock generation scheme. The DACs are no longer produced, and were obtained from surplus stock suppliers.
The digital sections are identical, but Luma-1 uses small SMD (Surface Mount Device) components to save space. A modular design was implemented, where each voice is on its own card for serviceability and future expansion or modifiability.
The power supply is the exact same model used in the LM-1, and amazingly it is still made in the USA! It is a linear power supply, which is heavier and more expensive, but doesn’t have any “switching noise” concerns of more modern supplies.
Finally, the enclosure is modeled after the original LM-1, with the same width and height to preserve the front panel user interface. Thanks to the smaller SMD components, the overall length of the enclosure is 4” shorter than the LM-1. The enclosure is made of 3 custom steel sections, each powder coated. The control panel and rear are illustrated with custom silkscreen printing. The side panels are wood, like the original LM-1, but with a variety of wood types available. Luma-1 weighs 25 lbs (a little over 11 kg).
