Record microphones, instruments, or line-level signals into your DSLR with the Comica Audio CVM-AX3, a dual-channel mixer designed for use in video production, ENG, music videos, and more. Mount it to a camera or tripod then attach important accessories to its integrated cold shoe mounts. Dual gain control knobs adjust levels for the two built-in preamps, which can be fed by the XLR-1/4" combo jacks or 3.5mm mini-jack inputs. With selectable 48V phantom power and 3V plug-in power, the CVM-AX3 ensures compatibility with a variety of microphones such as traditional condensers, shotguns, and lavaliers.

Thanks to 3.5mm main, aux, and headphone outputs, this mixer supports simultaneous routing to your camera's input, a backup recorder, and headphones for real-time monitoring. A mono/stereo switch allows the output signal to be optimized for your camera's input configuration. Powered by a single 9V battery, the CVM-AX3 offers up to 40 hours of battery life when phantom power is off, or up to six hours of operating time with phantom power engaged.

Q: 1. Hi is the phantom power switchable on each individual input - ie. can you have one input a phantom mic, the others not.....or is it all 4 on / all 4 off ?Thanks :)

A: Hi. yes you can have phantom power for each individual channel. The field mixer is good for the price. Thanks

Q: 2. what is the difference between the K1 and the K3 ?

A: The K1 model is analog only, the K3 offers both analog and digital audio. The other major difference is the K1 has XLR inputs only, the K3 has XLR / TRS Combo Inputs. You will be able to use XLR or 1/4" connections with the K3.

Q: 3. What’s the advantage of a digital signal vs an analog signal. I have the xlrk2m and was wondering is it would make a difference

A: If you are able to use the digital connection from this adapter to your camera, this means the signal stays digital going from the digital converter to the camera. There is no additional digital to analog converter the signal must pass through to be heard by the camera. This is ideal if your camera allows for a digital connection.

Q: 5. Does this unit support mid side microphones?

A: Unfortunately not, no Mid-Side setting .

Q: 6. Can the unit be used while charging (for uses beyond 10 hours)?

Q: 9. What are the advantages and differences to consider in relation to the Sony ECM-B1M?

A: They are very different microphones. The KM3 allows you flexibility to use other XLR mics. The B1M is more compact. If you pair it with a A7RM4 its a fully digital path. If you are looking for flexibility then get the KM3. If you want a small mic with some noise isolation then get the B1M.

Q: 10. Does this have an additional shoe mount on top?

A: No
