Sennheiser AVX Dynamic Range and Outdoor Distance Tests

https://youtu.be/uUSd_ulXdno Sennheiser recently introduced their new digital wireless system called the Sennheiser AVX. There are various kits available and in this episode I used the kit with the transmitter, receiver, and MKE2 lavalier microphone (their higher-end pro lavalier microphone).

We did a few tests to see how well the AVX does in terms of outdoor distance (keeping its signal without dropping out), and the dynamic range feature Sennheiser touts as preventing clipping and distortion when the sound gets much louder.

The outdoor distance test was as expected: Solid up to 50 meters, and my first dropout occurred at around 75 meters. You need to pretty much be in line-of-sight to get a solid signal at 50 meters. I never shoot this way, but it is good to know the limits of one's tools.

The dynamic range feature was way more impressive than I expected. It really works and sounds good! I feared it might be like Automatic Gain Control like they include in many of the DSLRs and that AGC feature is awful in those cameras. It stupidly pushes the gain up through the roof during silent sequences and that just makes an unbearably noisy mess of the audio. But on the AVX, it sounds very transparent and clean. I really like it!

Final review should be here later this week. Let me know if there are other things you'd like me to test before I have to send it back to my friends at B&H Photo.
