Important Power Information
Read Instructions!
Please read the Cre8audio Assembler Mixer User Guide completely before use and retain for future reference.
- Only use the DC power adapter provided by Cre8audio with Assembler. Using an incorrect power adapter can cause permanent damage to Assembler and the power adapter.
- Assembler is an electronic device. Exposure to water will cause Assembler circuitry to short circuit and may cause permanent damage.
- Do not attempt to modify Assembler. Tampering with the circuitry may cause permanent damage.
- Do not place heavy objects on Assembler. The user interface is mounted on a PCB that can be damaged if stressed by excessive weight.
- Do not attempt to repair Assembler. Please contact Cre8audio regarding malfunctions of any kind.
- Cre8audio is not responsible for any damage or loss caused by improper use of Assembler.
- Do not put your hands inside heavy machinery.
Eurorack Power Cable Information
- The Cre8audio Assembler Mixer is a Eurorack format synthesizer module. The module can be installed, rearranged, removed, and replaced in any compatible Eurorack case from Cre8audio, Pittsburgh Modular, or other manufacturers.
- The Cre8audio Assembler Mixer uses a standard 16 pin Eurorack ribbon cable to connect the module to a bipolar +/-12v power supply. Please pay very close attention to the orientation of the ribbon cable when adding and removing modules. The stripe on the ribbon cable marks -12 volt power. This stripe needs to line up with the -12 volt pins on the power supply and the -12 volt pins on the module. The Cre8audio Assembler Mixer includes reverse polarity protection so it will not be damaged when plugged in incorrectly; however, as a general rule, failure to match up the pins correctly can result in damage to one or all the modules in a case. On Cre8audio and Pittsburgh Modular cases the positive and negative voltages are clearly labeled. On the Cre8audio Assembler Mixer module, the power header is clearly labeled and keyed to ensure a safe and proper connection.
- Do NOT remove the Cre8audio Assembler Mixer module from any case while it is plugged in.
- Do NOT unplug power ribbon cables from the Cre8audio Assembler Mixer or case while the case is plugged in.
