You may not want every signal that goes through the Mixing Console to be mixed with your project. For example, you could set up a cue (talkback) microphone to communicate between the control room and recording booth.

This help topic will show you how to use an input bus to set up a cue microphone.

1. Add an input bus to your project.

2. Connect a microphone to an input on your sound card (for this example, we’ll use Mic/Inst 1).

3. In the recording booth, connect a pair of powered speakers or a headphone amplifier to an output on your sound card (for this example, we’ll use LineOut 3L/LineOut 4R).

4. Set up your input bus:

1. In the I/O control region of the input bus channel strip, click the Input Source button and choose the sound card input where your cue microphone is connected:
   

2. Click the Output button and choose the sound card output where your speaker or headphone amplifier is connected:
   

When you speak into the cue microphone, its output is sent to the recording booth without being mixed into your project output.
