Note: The information in this article applies only to Apollo x4.
It is highly recommended to always use the original power supply that came with your Apollo x4 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 x4 power supply are:
Current Draw: 4.2A
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.
Factory replacement power supplies can be ordered directly from Universal Audio by contacting Customer Support.
Apollo Twin X and Apollo x4 use a power supply that connects to wall outlets using a non-polarized C7 cable (female).

When traveling internationally, swap out the non-polarized C7 cable with one that is compatible with outlets in the country you’ll be visiting.
