Apollo Twin & Apollo Twin MkII Power Supply Specifications & Purchase Info

Note: The information in this article applies to both Apollo Twin and Apollo Twin MkII. For info related to Apollo Twin X, see the Apollo Twin X Power Supply Specifications & Purchase Info page.

It is highly recommended to always use the original power supply that came with your Apollo Twin or a factory replacement. However, if your power supply fails or is lost and you need to get through a session, you can use a generic replacement power supply that matches the original power supply's specifications as a temporary solution.

Important: Universal Audio is not responsible for any damage caused by using a non-factory power supply.

Here's what you'll need to consider when picking up a generic replacement power supply for your Apollo Twin:

  • Make sure that the replacement power supply matches the specifications of the original power supply exactly. Do not use a replacement power supply that does not provide the correct output voltage or current, or does not match the polarity of the original.
  • The exact specifications of the Apollo Twin power supply are:

Output: 12VDC
Current Draw: 1.5A
Polarity: Center Positive
Barrel dimensions (diameter): 5.5 mm (outside), 2.1 mm (inside)

  • Make sure that the replacement power supply fits snugly into the power connector on the back of the unit.
