Body: <p>I'm a non-professional user with a Black Magic Cinema Camera 2.5k (BMCC). I have a number of separate audio outputs that I want to record with the video in Black Magic Media Express so I use multiple audio channels that I can edit in post-production.</p>
  
  <p>The audio outputs are:</p>
  
  <ul>
  <li>Microphone 1 via XLR or 1/4" balanced</li>
  <li>Microphone 2 via XLR or 1/4" balanced</li>

  </ul>
  
  <p>I'm trying to find a product I can use to record these audio channels separately in Media Express.

  1. HyperDeck Studio Pro. Can record to SSD and/or via Thunderbolt to Mac/PC, sufficient inputs to maintain the audio channels.
  2. UltraStudio 4k. Can record via Thunderbolt to Mac/PC and has inputs needed to maintain all the audio channels + more.
  3. DeckLink Studio 4k. Has inputs I need. Can I use inputs at the same time and record with Media Express with multiple audio channels?
  4. UltraStudio Express. Can record via Thunderbolt to Mac/PC. Does it have the necessary inputs? Can I use inputs at the same time and record with Media Express with multiple audio channels?</p>

  The page you want to look at is the "Capture and Playback" page of the [Blackmagic Products page](https://www.blackmagicdesign.com/products). Any device on that page that says "four analog audio inputs" is a good bet. Media Express does indeed have the ability to record audio and video from an SDI input, and also audio-only from audio-only inputs, giving you a multichannel media file that you can then edit in post.
  
  However...I strongly suspect that the analog inputs of most (if not all) of these devices are line-level and don't supply phantom power. Depending on what sorts of microphones you have, that could be one or two reasons per channel you will not get a satisfactory result. Not to worry...you can buy a pair of microphone preamps that take mic-level inputs, possibly provide phantom power (if your mics require it), and deliver line-level signal to your audio inputs.
