presonus studio 2 6 usb audio interface issues

The idea is to be able to hear your direct signal while recording, to avoid latency. Settings less extreme get a combination of the two, with their signal levels in proportion to where the knob is positioned. Turn it completely to the right and you hear only the output coming from your computer or iOS device. Turn it fully left and you hear only the audio coming through the input.

The one feature that might be confusing to some is the Mix control. Operation is straightforward and generally quite intuitive. I was able to set it up easily with both my iPad Air and my MacBook Pro. Now that we’ve looked at the features, let’s talk about the AudioBox iTwo in action. No matter if you’re connecting to to an iOS device or to your computer, any MIDI device you connect will need to be self powered, there’s no bus powering like with USB MIDI interfaces. So even though this unit is iOS friendly, it’s not a true mobile interface, for iOS at least, because you need AC to use it with your iOS device. You have to connect the USB cable from the unit to your iOS device’s charging block to get power. When you do, you won’t see the AudioBox iTwo power up, because it’s not bus powered from your iOS device. If you’re connecting to an iOS device, you plug your dock connector cable from your device into the Device jack. In this configuration, the AudioBox iTwo is powered by your computer’s USB bus. If you’re using the box with a computer, you connect the included USB Type B cable from the interface’s USB port to that of your computer. The back panel includes MIDI In and Out jacks, 1/4” Main left and right outputs, a USB port, and the Device port, for connecting your iPad, iPhone, or iPod touch.

The front panel also contains a large master output gain knob, and headphone level knob. Knob-wise, you get in input level control for each channel, and there’s a global Mix control for varying between source audio and that from your computer or device, which allows you to monitor without latency.
