UMC204HD Rerouting

Contributor - Level 1

Recently got myself a UMC204HD and have been able to record without a hitch. Got a couple of questions that I can't find answers for though:

  • Can I reroute the DAW playback to the headphone jack on the interface? Or can I only use the main out?
  • If yes, does anyone have any clue if this is possible in Reaper? (And if possible, how?)

    Thanks in advance.

    I don't have the answer for you, but I'm in the same shape as you trying to figure out the UMC204.

    In my Reaper DAW software, I can't get it to record 2 tracks simultaneously when I have cords plugged into both Input 1 and Input 2. I can hear on my headphones as I'm recording it live the items going in both inputs. However, when I play it back, I learn that the DAW software through the USB is only recognizing (and playing back) the sound that comes through Input 1.....And this happens regardless of whether the mono/stereo is pressed or depressed, either way.....So basically, it's like Input #2 is worthless.

    Searching the forums and help section of my DAW, I'm not able to find an answer to this.

    Hi Pier and Joel,

    Welcome to the forums. Take a look at this diagram to see if it helps explain the inner-workings of the 204HD.


    While it's technically for the 404HD, the signals are the same for the 204HD with just two less inputs.

    @Pier: For your situation, take a look at the Monitor switch in quadrant A1 as well as the Mix knob in quadrant B2. The Mix knob controls the blend of Input1-4 with PB1-2 and the Monitor switch controls whether you are listening to the output of the Mix knob or PB3-4 only.

    @Joel: Make sure you have your track set as a Stereo track and make sure you have the track inputs set to both 1 and 2. I use Reaper daily with a 404HD and XR18 so we should be able to figure this one out quickly.

    Hope this helps,

    Hey Ken,

    Thanks for the reply! Useful diagram, gives me a better idea of how to play with the outputs.

    Will definitely try it out.
