Neuzeit Instruments assures that a properly constructed modular system based on commercially available enclosures, power supplies, power distributors and a coherent selection of modules can meet the requirements set by international certification authorities. In the following sections, the term device refers to the Eurorack module that has been properly installed, powered, and patched as part of a system.

FCC

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Changes / modifications not approved by Neuzeit Instruments could void the userís authority to operate the equipment.

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications.

CE

Guidelines to reach electromagnetic compatibility in a Eurorack system

By following these rules, you can ensure that your Eurorack system meets electromagnetic requirements.†

  • Use a fully enclosed housing, made of conductive material (metal)
  • Make sure that there are no open holes in the housing. Close all unused spaces with blind panels.†
  • Use only third-party components such as power supplies and modules†that also meet EMC.†
  • Use a high-quality power supply and a solid power distribution subsystem with good grounding. The latter means that solid†ground planes and wide ground traces are preferred.†
  • Use ferrite beads and electronic filters for any 110-230VAC line going into the housing.
  • Keep all cables, power or patch cables, as short as possible.†
