Using a Personal Laptop

Setting Up Your Laptop

1. Connecting your laptop

   • Connect your laptop to the UMC1820 using the USB cable connected to the left rack

   • In your DAW's audio preferences, select UMC1820 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 UMC1820 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 UMC1820 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)

   • Select LINE/INST for your input channel

     • Use INST for guitars/basses

     • Use LINE for mic or line inputs

   • Input gain is controlled using the gain knobs on the front panel

   • There are two phantom power switches, one for inputs 1-4 and another for 5-8. Enable phantom power when connecting condenser microphones.

3. Using the studio speakers

   • The UMC1820 feeds into the Grace m908 via balanced analog outputs

   • To listen to the UMC1820 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 UMC1820 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 MONITORING knob on the UMC1820 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

6. 'Opto' Digital I/O button

   • Ensure ADAT is selected. This is connects the ADA8200 preamplifier to the interface (software inputs 11-18).
