Using the USB interface for  laptop or studio computer

Setting Up

1. Connecting your laptop or studio computer

   • Connect your laptop to the Scarlett using the USB cable connected to the left rack

   • In your DAW's audio preferences, select Scarlett 18i20 as both input and output device

2. Using inputs

   • Connect your mic/instrument into either of the front-panel inputs 1-2

     • To use inputs 3-8, patch a desired wall or floor panel input into the labeled focusrite 18i20 patch points

       • e.g. If I wanted to use input 77 in the control room floor panel, I would check the patch bay in the back of the room, and connect a cable from the FP-105 77 patch point to 18i20 input 3

     • To use the ADA8200 inputs, patch a desired wall or floor panel input into the labeled ADA8200 patch points (these will show up as DAW inputs 11-18)

   • Input gain is controlled by clicking the button assigned to each channel and using the input knob to adjust accordingly.

   • Phantom power is not normalized throughout several channels, and can be turned on for an individual channel by engaging the button once you have selected the channel you wish.

3. Using the studio speakers

   • The Scarlett 18i20 feeds into the Grace m908 via balanced analog outputs

   • To listen to the 18i20 outputs on the speakers:

     • On the Grace m908 select the behr-in-st input (bottom left button)

   • To control your main output level

     • Use the main knob on the Grace m908

     • The "MAIN OUT 1-2" knob on the UMC1920 should be set to fully clockwise

       • This ensures proper gain staging into the monitoring system

     • The "Monitoring knob" should be set as needed - typically fully clockwise for playback unless input moniotring is desired.

4. Using headphones

   • The Scarlett 18i20 provides two headphone outputs on its front panel

   • Each headphone output has its own volume control

   • The headphones connected here are independent of the Grace m908 

5. Monitoring inputs

   • The Output knob on the Scarlett controls blend between direct input signal and DAW playback

   • For standard DAW monitoring usage, turn the knob fully clockwise

   • Only turn this knob counterclockwise if you explicitly need zero-latency input monitoring
