Step 1: Hook-Up

This section describes how to connect instruments and audio sources to the U-PHORIA UMC1820.

Laptop Setup:

Connect the UMC1820 to a laptop via the provided USB cable. Connect microphones (e.g., C-1) to inputs 1 and 2, and a guitar to input 1 or 2. Connect studio headphones to the headphone output. Ensure the power adapter is connected to the UMC1820 and plugged into a power source.

Desktop Setup:

Connect the UMC1820 to a desktop computer via the provided USB cable. Connect microphones (e.g., C-1) to inputs 1 and 2, and a guitar to input 1 or 2. Connect studio monitors (e.g., B2031A) to the MAIN OUTPUTS. Connect studio headphones (e.g., HPS3000) to the headphone output. Ensure the power adapter is connected to the UMC1820 and plugged into a power source.

Step 2: Controls

This section details the front and rear panel controls of the UMC1820.

Front Panel Controls:

• 1. INPUTS: XLR/TRS combo connectors for microphones, instruments, or line-level audio sources.
• 2. P+48V: Switches for +48 Volt Phantom Power to XLR inputs 1-4 and 5-8. Use with caution for microphones that do not support phantom power.
• 3. LINE/INST: Selects line level or instrument level input for the 1/4" connector. Use INST for direct guitar connection.
• 4. PAD: Reduces input signal level for XLR and 1/4" inputs, useful for hot signals.
• 5. SIG/CLIP LEDs: SIG indicates an audio signal is present. CLIP illuminates if the input signal is too high.
• 6. GAIN knobs: Adjust input level. Set so CLIP LED does not illuminate, even during peaks.
• 7. IN 1-2 or 1-8: Selects direct analog input sources for monitoring.
• 8. STEREO/MONO: Selects stereo or mono monitoring.
• 9. MONITORING knob: Adjusts the mix between direct inputs and computer playback (IN: direct only, MIX: 50/50, PB 1-2: computer playback only).
• 10. DIM switch: Reduces the MAIN OUT output level.
• 11. MUTE switch: Cuts the MAIN OUT signal.
• 12. MAIN OUT knob: Controls the MAIN OUT output level.
• 13. OPT I/O: Selects operation for rear panel optical and coaxial ports (SPDIF or ADAT modes). Caution: Re-boot required when changing modes.
• 14. PHONES source selector: Selects audio source for headphone outputs (1-2 for MIX signal, 3-4 for computer playback).
• 15. PHONES level knobs: Adjust headphone listening level.
• 16. PHONES outputs: 1/4" TRS stereo headphone outputs.
• 17. MIDI I/O LEDs: Indicate MIDI activity.
• 18. POWER LED: Indicates unit is powered on. +48V LED indicates phantom power is active.
• 19. POWER switch: Turns the unit on/off.

Rear Panel Connections:

• 20. DC IN: Connect the supplied power adapter here.
• 21. USB type B connector: Connect to a computer via the supplied USB cable.
• 22. MIDI IN/OUT: Connect to external MIDI controllers and modules.
• 23. ADAT/S/PDIF Optical I/O: Supports S/PDIF, ADAT, S/MUX formats.
• 24. S/PDIF I/O ports: RCA coaxial connectors for S/PDIF input (channels 9-10) and output (channels 11-12).
• 25. LINE OUT 3-10: Balanced 1/4" TRS outputs for additional monitoring and recording. Output levels controlled by DAW.
• 26. MAIN OUT: Balanced 1/4" TRS outputs for connecting to studio monitors. Adjust source with MONITORING controls and level with MAIN OUT controls.

Step 3: Getting Started

Follow these steps to begin using your UMC1820.

1. Driver Installation (Windows): Visit behringer.com to download the latest UMC1820 USB driver. Unzip the file, run setup.exe, and follow on-screen instructions. (Mac users: No drivers are needed for OS X).
2. Connections: Connect instruments and audio sources to the UMC1820. Connect the unit to your computer via USB. Connect MIDI devices to MIDI IN/OUT ports. Connect studio monitors to MAIN OUTPUTS and headphones to PHONES outputs.
3. Initial Settings: Set GAIN, MONITORING, and PHONES levels to minimum.
4. Power On Sequence: Turn on the UMC1820 first, then any other external equipment.
5. Phantom Power: Check if your microphones require +48V Phantom Power and engage the P+48V switch if necessary.
6. DAW Recognition: Ensure your Digital Audio Workstation (DAW) software recognizes the UMC1820 as the audio and MIDI input/output device.
7. Gain Adjustment: While playing a source or singing into a microphone, adjust the GAIN for each analog input. Set the gain so the CLIP LED does not illuminate, even during the highest signal peaks.
8. Monitoring Level: Listen through headphones or studio monitors and adjust the PHONES or MAIN OUT volume controls to a comfortable and safe listening level.
9. Channel Verification: In your DAW, confirm that all input and MIDI channels are functioning correctly. Play each channel individually to verify its presence.
10. Playback Verification: Ensure playback from your DAW reaches the UMC1820. Adjust the MIX knob in the monitoring section to hear playback. Note that output levels for channels 3-10 and digital outputs are controlled solely by the DAW.
11. Recording: Enjoy playing along and making recordings with your DAW. Listen back via monitors or headphones and adjust the monitoring MIX control as needed.
