# Creating a mix-minus on a QOR

### Configuration of the local Input and Output

### Configuring the Input

1. Connect the output of your phone hybrid to one of the Analog Inputs on your QOR. For this example, we'll use Analog Input 8.

> Name it something descriptive so you know what is connected. In our example “Telephone”

We know that we need to create a dedicated audio feed that goes back **TO** our Phone system. This is where we get the term “To: Source”. It’s also why some of the outputs on the QOR have the prefix “To:” It’s a simple matter of picking the right one.

### Configuring the Output

1. Connect the input to your phone system to one of the local outputs. In this example, we’ll use Analog output 4

> Again, name it something descriptive. In our example “To Telephone”
2. From the output drop-down list, pick To: Analog 8 (you have to scroll down past the normal outputs)

This is our way of telling the system we want the "TO: Source" (remember, that's a mix-minus) of whatever we plugged into Analog INPUT number 8. Put another way, Output 4 becomes the mix-minus of whatever is plugged into Analog 8 input.

In this configuration, what comes out of Analog Output 4 is everything EXCEPT what comes in on Analog Input 8, which, in this case, is precisely the configuration we want.

## Configuring the Source Profile

The last step is ensuring we correctly set the Source Profile in our QOR console engine. When you create a new source profile, select **Phone** for the Source type **BEFORE** you click the Create button.

> [!WARNING]
> This also applies to Codec source types. If you select Line (or other source types), the console will not know that it needs to create this mix-minus feed automatically.
