U-PHORIA UMC1820 Hook-up

Step 1: Hook-Up
Small Studio

U-PHORIA UMC1820 Controls

Step 2: Controls

1. INPUTS accept XLR or ¼” connections from microphones, instruments, or line level audio sources.
2. P+48V switches turn on +48 Volt Phantom Power to XLR inputs 1 to 4, and 5 to 8. Carefully read your microphone’s documentation before turning on phantom power, as it can damage some microphones.
3. LINE / INST selects line level or instrument level input source at the ¼” connector. Select INST when connecting a guitar directly
4. PAD reduces the level of input signals from the XLR and ¼” inputs. For example, this is useful if the XLR input is not from a microphone.
5. SIG LED indicates an audio signal is present. The CLIP LED turns on if the audio input signal is too high.
6. GAIN knob adjusts the input level. Adjust so the CLIP LED does not turn on, even during the highest peaks.
7. IN 1-2 or 1-8 selects direct analog input sources 1-2 or 1-8 for monitoring.
8. STEREO/MONO selects stereo or mono monitoring.
9. MONITORING knob adjusts the mix between the direct inputs and computer playback:
   IN: only direct inputs (0 ms latency)
   MIX: 50/50 mix of inputs and playback from computer PB 1-2: only playback from computer
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 the operation of the rear panel optical and coaxial RCA I/O ports: SPDIF: Optical input S/PDIF 9-10, Optical output S/PDIF 11-12. Coaxial input off, Coaxial output S/PDIF 11-12. ADAT: (@ 96 or 88.2 kHz) Optical input S/MUX 11-14,optical output S/MUX 13-16. Coaxial input S/PDIF 9-10, Coaxial output S/PDIF 11-12.
    (@ 48 or 44.1 kHz) Optical input ADAT 11-18, optical output ADAT 13-20. Coaxial input S/PDIF 9-10, Coaxial output S/PDIF 11-12. Caution: Do not change between S/PDIF and ADAT modes while operating your DAW / music program, because the UMC1820 does a quick re-boot. Close all applications before changing modes, and then wait until the unit has been recognized again by your operating system before restarting your music application.
14. PHONES source selector switch:
    1-2: Listen to the stereo MIX signal channels
    1-2 from the monitoring section.
    3-4: Listen to the playback signal from computer output channels 3-4.
15. PHONES level adjustment. Start at minimum and then turn up to a comfortable and safe listening level.
16. PHONES ¼” TRS stereo headphone outputs.
17. MIDI I/O LEDs indicates MIDI activity.
18. POWER LED is on if the power switch is pressed in and the unit is powered via the supplied power adaptor.
    +48V LED is on if either phantom power switch (1-4 / 5-8) is on.
19. POWER switch. Press in to turn on the unit.
    The POWER LED will turn on.
    Rear Panel
20. POWER IN connect to the supplied power adaptor only. Connect the power adaptor to an AC mains supply that is properly configured for the unit. A cable holder above the input prevents the power connection from being accidentally pulled out.
21. USB type B connector. Connect to a computer USB port with the supplied USB cable.
22. MIDI IN/OUT connect to external MIDI controllers and modules.
23. ADAT or S/PDIF Optical I/O ports support S/PDIF, ADAT, S/MUX. Input channels are 11 to 18, outputs are 13 to 20. The front panel OPT I/O-switch (13) selects the operation of these ports.
24. S/PDIF I/O ports: RCA coaxial S/PDIF inputs come in from external sources as input channels 9 to 10. S/PDIF output channels are 11 and 12.
25. LINE OUT 3-10 balanced ¼” TRS outputs for additional monitoring and recording. The output signals come directly from the computer after being converted to analog by the UMC1820. The output levels are only controlled by the DAW.
26. MAIN OUT balanced ¼” TRS outputs connect to powered studio monitors for playback and mixing. Adjust the source using the front panel MONITORING controls, and adjust the level using the front panel MAIN OUT controls.

Step 3: Getting started

1. Windows* users: Please visit behringer.com and download the latest UMC1820 USB driver. Unzip the file, double-click the setup.exe and follow the on-screen instructions. Mac* users: For OS X*, no drivers are needed.
2. Connect instruments and audio sources to the UMC1820. Connect to a computer via the provided USB cable. Connect a MIDI keyboard, controller, or other MIDI device via the MIDI ports on the rear panel. Connect a pair of studio monitors to the MAIN OUTPUTS. Connect a pair of studio headphones to monitor input levels and playback from your audio software.
3. Start with the GAIN, MONITORING, and PHONES level at minimum.
4. Turn on the UMC1820 first, followed by any other external equipment.
5. Check to see if any of your microphones require Phantom Power.
6. Make sure your DAW software recognizes the UMC1820 as the audio and MIDI input and output device.
7. While playing a source, such as a guitar, or singing into a microphone, adjust the GAIN of each analog input. You can first make it clip, and then turn the GAIN down just enough so the CLIP LED does not come on, even during the highest peaks.
8. Listen to your playing in the headphones or studio monitors, and adjust the PHONES or MAIN OUT volume controls to a comfortable and safe listening level.
9. On your DAW, make sure that all input and MIDI channels are working correctly, with audio and MIDI present. Play each channel one at a time to confirm it is present in your DAW.
10. Verify that the playback from your DAW is reaching the UMC1820. Adjust the MIX knob in the monitoring section to hear the playback. Note that the volume level of the other outputs 3 – 10 and the digital outputs is adjusted only by the DAW.
11. Enjoy playing along and making recordings on your DAW. Playback and listen in your studio monitors or headphones. Adjust the monitoring MIX control as desired.
