For part 2 of the Beachtek DXA-SLR PRO audio interface review, I got together with Ríchard Izarra in one of his extremely brief visits to Miami to test audio with his new Blackmagic Pocket Cinema Camera. Ahead you’ll see (and hear) a brief audio/video clip.
What you may have missed from part 1 of this review
In part 1 of this review, I shared:
- What’s a DXA-SLR PRO interface, and what is its purpose?
- CLARIFICATION: Why the these audio interfaces differ from others I have reviewed
- Key features/specs/details to look for in analog audio interfaces for cameras
- DXA-SLR PRO design, features, and specs
- Mounting of an audio interface onto a camera
- SIDEBAR: About audio limiters
- SIDEBAR: AUDIO BRACKETING: Alternative to limiters, but with its own limitation!
- Five audio/video tests
- Initial conclusions after watching/hearing these videos
- What we’ll cover in upcoming parts of this DXA-SLR PRO review
If you haven’t yet read part 1, you are welcome and encouraged to do so. Part 2 will still be here when you return.
Beachtek’s observations about the Blackmagic Cameras’ audio
Prior to doing this test, I discussed with Beachtek about how to adjust the input of the Blackmagic Pocket Cinema Camera when used with the DXA-SLR PRO, given the fact that (at least as of publication time of this article), there are no internal audio meters in this camera. Beachtek stated that with the current firmware, we should be setting the camera input to maximum input for best results. (This saved me the trial-and-error approach I would have had to do.) This is almost the opposite of the approach with any other (non-Blackmagic) camera, where the recommendation is to set the camera’s input to much closer to the minimum (i.e. around 25–30% with a Canon 7D, or to the absolute lowest setting with a Panasonic Lumix GH3). But the Blackmagic cameras are so unique, that one more atypical characteristic shouldn’t surprise us too much.
How to mount the DXA-SLR PRO with the Blackmagic Pocket Cinema Camera
The upper screw on the DXA-SLR PRO fits fine within the hole in the Blackmagic Pocket Cinema Camera. However, the screw appeared to me and Ríchard to be much longer than the hole’s depth, so in actual use, a thick washer (or perhaps two standard washers) should be used. However, it stayed still as-is for our test, which you’ll see below. If and when I get any definitive conclusion about the mount from Beachtek with the Pocket Cinema Camera, I’ll update this article.
Video shot with Blackmagic Pocket Cinema Camera + Beachtek DXA-SLR PRO
Thanks to Ríchard Izarra of PRODU.com, I was able to make the following short recording. Frequent readers will already know that Ríchard’s latest camera acquisitions have been both a Canon XA20 (which comes factory-ready with balanced XLR audio inputs plus metering) and now a Blackmagic Pocket Cinema Camera (which lacks balanced XLR inputs or any type of audio metering as it comes from the factory).
While editing, I took out the chroma intentionally. However, the only change I made with the audio in post was to remove the unused channel and to normalize. During the recording, we used Ríchard’s ElectroVoice RE50N/D-B high-output dynamic microphone, the camera input level was set to 100%, and the input potentiometer on the Beachtek DXA-SLR PRO was set to about 1:00 (clock nomenclature), which gave us a good level.
Ríchard’s appreciation of the audio quality and design
Ríchard often uses professional XLR microphones, and they are often dynamic. He also often connects two microophones and wants to be able to have each on its own track. Other than the apparent need for a washer, Ríchard liked the design and the resulting audio quality produced by the combo. He plans to purchase a DXA-SLR PRO sometime soon, and he’s wondering who will supply him with a washer: Beachtek or some hardware store.
What we’ll cover in upcoming parts of this DXA-SLR PRO review
- DXA-SLR PRO with at least one traditional video camera
- DXA-SLR PRO with Panasonic Lumix GH3 (as long as I can get access to one)
