View source for Apollo x8 Interface

We have Apollo x8 interfaces installed in the four Music Tech Labs, both Audio Mixing Benches and the 5.1 room.

== Intro ==
* We have Apollo x8 interfaces installed in the four Music Tech Labs, both Audio Mixing Benches and the 5.1 room.
* They are multichannel interfaces with
** HI-Z inputs for guitars
** Mic inputs with XLR jacks
** Line inputs with 1/4" jacks
* The interfaces and software were configured to work in the various labs.  
* The Music Tech labs make use of more inputs and outputs of the interface.  
* The Audio Mix Benches are set up in a similar way to make moving between labs easier.
* Not all of the inputs and outputs are connected in the various labs.

==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.

=== Selecting Inputs ===
* Press the Preamp knob to toggle between inputs 1-4.
* The number over the corresponding input on the LED display will light up.
* Press the INPUT button to toggle between MIC and LINE for the current input.
* Connecting a cable to HI-Z 1 or HI-Z 2 will force the inout switch to HI-Z

=== Input Controls for Inputs 1-4 ===
* Input: toggles between MIC and LINE for the current input.
* Low Cut Filter: Enables a filter with a cutoff frequency of 75 Hz with a slope of 12 dB per octave.
** Affects Mic, Line and HI-Z inputs
* +48V: Press to turn on phantom power.  
** When pressed the light will flash red. 
** When the red light is solid phantom power is enabled.
** Only use with condenser mics.
* Pad: When enabled, the channel’s XLR Mic input signal level is attenuated by 20 dB. 
** Does not effect the Line or Hi-Z inputs.
* Polarity: Inverts the phase of the input by 180 degrees.
** Leave off
* Link: Links the preamp controls of adjacent preamp channels together.
** 1 and 2 and 3 and 4
** Only the same types of inputs can be linked.
*** Mic/Mic or Line/Line
*** Does not work HI-Z inputs

== Outputs ==
* There are 8 line outputs on the back.  
* Not every lab is using all 8 outputs.  

== 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.  
* Below are table with the list of the inputs and outputs  
* Some are physical inputs and outputs and others and virtual connections from the UA Console app.
