Does it require an external power supply when usin

Does it require an external power supply when using it with and iPad pro?
Asked by: Mark
Yes, the PreSonus Quantum ES 4 USB-C Audio Interface will require use of an external power supply when connected to an iPad Pro, as mobile devices often cannot provide enough bus power through a single USB-C connection. You will need to use a 5V DC, 2.6A (approximately 13W) power source connected to the aux port on the ES 4, which can be a portable USB battery power bank or wall adapter.
