Sennheiser AVX Digital Wireless System

Let's get this out of the way first. The Sennheiser AVX digital wireless system is not cheap. Coming in at a whopping $899 USD, but holy crap is it worth it! The AVX is perfect for those video amateurs or professionals that answer 'YES' to the following questions:

  • Is audio something you struggle with time and time again?
  • Is your knowledge of audio limited and do you really not care to learn more about capturing solid audio?
  • Have you ruined a project(s) in the past because of audio issues?
  • Are you a 'run-and-gun' type shooter and don't have time to worry about audio settings?
  • Do you want a 'plug-and-play' option for audio?

If you answered 'YES' to any of the above, the the AVX system is something you should really consider adding to your workflow. First and foremost, Sennheiser's AVX system is a true 'plug-and-play' option for audio. You literally plug this thing in, power it on, pair the modules (first time only, because they remember each other after the first power up), and start recording. It's amazing! The AVX auto adjust gain controls of its 24bit, 48Hz audio signal (which is also AES 256-bit encrypted) allowing it to normalize for changing sound environments. So again - you do not need to worry about gain controls or any of that craziness when you're using the AVX. Oh and did I mention distance this thing can record? No? Well check out this video:

Now if you're a seasoned audio professional, or you just understand audio and how to capture the good stuff, then you're going to have to live with how automated this system really is. There is no adjustment of the audio signal bitrate or quality. It's set at 48Hz with a 24-bit depth and that's what you get. Larry Dickerson (aka @GeekyNerdDad) noticed that when you plugged this system into a dedicated recorder and tried to record at a 96Hz (16bit or 24bit) on the recorder it caused the audio to take on a tinny sound. We think it's because the recorder is trying to "upscale" audio that is just not there. It's like trying to record 4K with a 1080 sensor. That's not a big deal though, as most - if not all - of industry record at a 44.1/48Hz quality level.

Ultimately, the AVX digital wireless system is BAWS Level Status when it comes to audio recording and ease of use. The 'plug-and-play' functionality of it is simply an engineering marvel and it is amazing how Sennheiser harnessed this power in such a small, durable, cool looking package.
