Key Features
- For ALEXA Mini & Compatible Cameras
- Low-Noise Preamp, 100 dB Dynamic Range
- Allows for Recording Directly to Camera
- 2 x Transformer-Balanced XLR Inputs
Designed primarily for the ALEXA Mini, but compatible with cameras such as the RED DSMC2, the Beachtek DXA-ALEXA is a low-noise preamplifier which connects directly to your camera, capturing audio through its transformer-balanced inputs and obviates the need for external syncing. The preamp itself sports a 100 dB dynamic range, and the construction of its inputs ensure galvanic isolation, as well as high common mode rejection in the face of common obstacles, such as electromagnetic interference.

Do you need any special attenuator cables to make it work with the Canon R5C or will a 5-pin XLR to 3.5mm work?
You could use an XLR 5-pin female to 3.5mm TRS male cable like the Wooden Camera Single 3.5mm TRS to 5-Pin Female XLR - 18" (B&H # WO808010) to send line level audio from the Beachtek DXA-ALEXA Low-Noise Preamplifier to the Canon EOS R5 C Mirrorless Cinema Camera. As another option, you can use the 3.5mm mic output on the DXA-ALEXA to send mic level audio to the camera's 3.5mm TRS input.

question
This Beachtek unit has such a better layout than most of Beachteks other models, not to mention its very aesthetically pleasing. Its a little disappointing that they specify this unit as being engineered for one or two cameras in particular. Would this also be usable with a DSLR like the Canon 5Dmk3 or a small video camera like the Canon XC-10? Or are the higher quality components advantages only realized with the Alexa or a RED unit? Thanks in advance
It was designed withe ALEXA in mind: Line Out: 5-pin balanced output at +4 dBu.But there is no reason it could not be used with other cameras: Mic Out: 3.5 mm unbalanced auxiliary stereo output

We could use this on the Amira 5-pin input as well, right?
The balanced 5-pin output will have the same pin configuration for everything in that line.
