Note: This article only applies to Apollo Thunderbolt Desktop models with Line 3/4 outputs.
There are a couple of scenarios where you may want to send a separate mix to the Line 3/4 outputs on your Apollo Thunderbolt Desktop - for example, if you need to send a custom headphone mix that is different from your monitor mix to a headphone amp, or if you want to send a stereo signal to a piece of outboard gear for processing. This article explains how to set up the Line 3/4 output on the Apollo Twin for these kinds of scenarios.
The routing to the Line 3/4 outputs on the Apollo Twin is managed via the CUE OUTPUTS popover, which is accessed by clicking the CUE OUTPUTS button on the right side of the Console window:
There are two available SOURCE options for the Line 3/4 output - "LINE 3/4" and "MIX":
|
LINE 3/4 To send a separate, discrete mix to the Line 3/4 outputs, set the SOURCE to "LINE 3/4". This is most commonly used when sending a custom headphone mix to a headphone amp via the Line 3/4 outputs, or when sending a stereo signal out to an outboard piece of gear for processing. Once the SOURCE is set to LINE 3/4, signal can be sent directly to these outputs by selecting the Line 3/4 outputs within the DAW. |

MIX To mirror the monitor mix to the Line 3/4 outputs, set the SOURCE to "MIX". This will route any signal being sent to the Monitor L/R outputs to the Line 3/4 outputs as well. This is useful for sending the monitor mix out to a headphone amp if a discrete headphone mix is not needed. Note that when the SOURCE is set to "MIX", full line level signal is sent out of the Line 3/4 outputs with no volume control. If volume control is needed when sending the monitor mix to the Line 3/4 outputs, we recommend using the ALT Monitoring feature in Console or an external volume control. For details on ALT Monitoring, see the "ALT Monitoring Overview" section of the UAD Console For Apollo manual Note: The "MIX" source is labeled "MON" in UAD 9.0.2 and older. |
If "LINE 3/4" is unavailable as a SOURCE option in Console, check Console > Settings > Hardware and make sure ALT COUNT is set to "0" as shown in the screenshot below. If ALT COUNT is set to "1", the Line 3/4 outputs will be unavailable for routing from the DAW.
