2) get your plugs right first.
mic > xlr cable > audiobox (phantom power +48V on) > USB > computer > DAW.
-if i'm not wrong it should be bus powered (powered via USB)
-make sure it's not plugged into a USB hub. best if it's back of the computer or direct usb port.
3) Make sure ASIO drivers are installed well.
4) power up your cubase DAW. under Devices > Device Setup > VST Audio Bay (or there'll be any parts that allows you to choose your audio interface/soundcard. make sure presonus audiobox is chosen.click OK.
5) press F4. this is where you configure your presonus audiobox's inputs and outputs.
under inputs , your audiobox has 2 inputs. #1 and #2.
under Output just put Stereo Out will do. your presonus has only 2 outputs.
*No audio input still? like I said, check +48V / Phantom power. AT2035 needs phantompower.
6) create track , arm + monitor track (the little yellow speaker) to record, and go.
enjoy.
