I) Using the Presonus interface

You can plug usb into your own computer or the iMac in the room.

II) Using the M-AUDIO OXYGEN25 MIDI keyboard

Plug the MIDI keyboard using a USB 2.0 cable (should already be plugged into the back of the keyboard, otherwise can be found on the shelf with the analog outboard gear in the back-right corner of the control room) into the black multi-USB port on the desk next to the mac mini. Make sure the keyboard is on (switch on the back of the keyboard). Next, with Logic open, in the toolbar at the top of the screen, click on Logic Pro X > Settings > MIDI. In this tab, click on 'Inputs'. On the 'Inputs' page you should see a list of five possible MIDI devices. Make sure that 'Oxygen 25' is written in white as opposed to gray – this means that Logic has recognized and is using this MIDI input. On the interface, select the 'usb' button to the left of the main knob to get midi signal into your DAW.  The keyboard should now be set up for playing on MIDI tracks. If it is not working, unplug the keyboard and retry the steps above.  Process is similar for other DAW's.  

III) Using the AKG K245 Headphones

To use the headphones, plug them into the 1/4" headphone output in the bottom left corner on the front of the presonus audio interface. To control headphone volume, turn the phones knobs up or down. If you are recording audio through the interface using headphones, turn the "mixer" knob left towards the input setting. This will make it such that the input into the interface (whatever you're recording) goes straight through the interface and into your headphones.  As opposed to turning on 'input monitoring' in your DAW (the 'I' button next to 'R' on a Logic track that allows you to hear what you're recording) and using that to hear yourself when recording, this eliminates any latency as the signal goes directly from the input channel into your headphones.  Turning the knob entirely to the right eliminates direct monitoring entirely and any setting in the middle blends direct input and playback signal.

You can also use your own headphones in the project studio. There is a 3.5mm (headphone/aux size plug) to 1/4" instrument cable sized jack) adapter plug in the back of the USB96 interface**. Simply plug your headphones into this adapter.

**do not move this 3.5mm to 1/4" adapter and always put it back next to the interface after use if removed from the interface.

IV) Using the Groove Tube GT55 Cardioid Condenser Microphone

Plug into the Mackie Big Knob audio interface using an XLR cable (this should already be set up in the project studio). Make sure phantom power ('+48V') is switched on on the front of the interface and that the button is illuminated red.  Make sure the interface is powered on and plugged into the hub, and that your DAW's audio settings have their audio device set to 'BIG KNOB STUDIO'.   Use the gain knob corresponding to the input you have used on the interface to set a level for the microphone.

The GT55 microphone is a side-address microphone with a cardioid polar pattern.  The GT55 logo should be facing the sound source being recorded (see image).  For instance, if recording a vocalist who is parallel to the microphone, the microphone should be pointed vertically towards the ceiling and the vocalist should sing into the side of the microphone.

V) JBL Monitors

If sound is going into your DAW and is shown on the meter on the interface, and all the correct settings have been selected as outlined above, the issue may be with the monitors.  First, make sure they are powered on (the 'RMC' button on the left speaker should be illuminated and a small green bar should appear on the meter).   If this does not fix the issue, look at the back of the speaker.  In the 'Active Input' section, the analog source should be illuminated.  If it is not, hit the 'input' button on the front of the speaker and press the '+' button until the 'analog' light is illuminated.
