Audio Interface - Mixing Bench

This lab has a Apollo x8 audio Interface which has multiple inputs and outputs. 

Inputs

• On the front there are two HI-Z inputs inputs (labelled HI-Z 1 and HI-Z 2)
  • Theses are for low level signal like electric guitars.  Only use mono 1/4 cables.
• There are 4 XLR mic inputs on the back of the interface.
  • There is a panel with 4 XLR jacks below the interface.
  • These are connected to the 4 mic inputs.
  • Microphones can be connected to these inputs using XLR cables (not included in the room).
  • Each input has:
    • Trim control knob for setting input levels
    • Pad for reducing input levels
    • 48V Phantom Power for powering condenser microphones
    • Low cut filter.
• There are eight 1/4" line level inputs on the back.
  • Theses are not connected to anything  

Outputs

• Outputs 1 and 2 are connected to the Mackie Big Knob volume box.
• The other outputs are not being used.

Labeling

• The various audio applications may refer to the inputs and outputs with slightly different names.
• We have tried to set the preferences to meaningful names but sometimes they may revert back to the default names.

Outputs

• The Main outputs come before the line outputs.
• This makes the numbering of the analog outputs confusing. 
  • For example analog output 1 is output 3.
