If you use a voltage adapter, it *will not* work. You need to use a straight-through adapter that gives the power supply the full power that it needs. We have regularly heard of issues like this with voltage adapters.
Alternative approaches include: (A) Contact technical support or (B) Use your own power supply.
If you would like to use your own power supply, it needs to have
(1) 9 V DC output
(2) regulated output
(3) At least 1.5 A output current capacity
(4) a 2.1 x 5.5 mm output barrel jack
(5) center-positive output
