This lab has a MOTU 828mk3 audio Interface which has multiple inputs and outputs. Unfortunately, the order and labeling of the inputs and outputs in the audio applications can be confusing.
Contents
Inputs
- There are two XLR/1/4" mic/instrument inputs on the front.
- Microphones can be connected to theses inputs with XLR cables.
- Guitars can be connected with 1/4" cables.
- Each input has:
- Trim control knob for setting levels
- Pad for reducing input levels
- There are eight 1/4" line level inputs on the back.
- Inputs 1 and 2 are connected to the patchbay.
- The main outputs of the mixer are connected directly to inputs 3 and 4.
- The other inputs are not being used.
- Do not connect or disconnect cables on the back.
Outputs
- There are two XLR Main outputs on the back.
- Theses are connected directly to the Mackie Big Knob volume box input A.
- There are eight 1/4" line level outputs on the back.
- Outputs 1 and 2 are connected to the patchbay.
- The other outputs are not being used.
- Do not connect or disconnect cables on the back.
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.
Inputs
- Mic/Instrument inputs come before the line inputs.
- This makes the numbering of the analog inputs confusing.
- For example analog input 1 is input 3.
| MOTU Inputs | Software Label |
| Mic/Instrument 1 | Input 1 |
| Mic/Instrument 2 | Input 2 |
| Line 1 | Input 3 |
| Line 2 | Input 4 |
| Line 3 | Input 5 |
| Line 4 | Input 6 |
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.
| MOTU Outputs | Software Label |
| Main Out 1 | Output 1 |
| Main Out 2 | Output 2 |
| Line 1 | Output 3 |
| Line 2 | Output 4 |
