Comica Audio CVM-AX3 Reviews

Convenient Format But Noisy

By David
Rated 2 out of 5
Date: 2020-06-25

Unit purchased for live-streaming setup: XLR-condenser audio feed into external camera feeding HDMI into capture card into Mac (running Ecamm Live). I was able to easily rig a dummy battery setup and the physical form factor is convenient. But the self-noise is far too high. I have demoted the product to B or C level rigs.

Worked well with one major problem

Pro: Does everything indicated. Con: MAJOR problem. When mounted directly onto my Canon HF G-30 produced a buzz/mum. I have a NRG light bracket I attached to the camera and mounted the Comica off-camera to use with my Sennheiser wireless mics for the veteran's interviews
