Designed for bringing in two separate audio signals and mixing them together for use with camcorders, DSLRs, or other video recording devices with only one audio input. Its 3.5mm aux input allows for other devices to be installed, like a phone. The CMX-2 is also able to be mounted on a tripod alone, but can also be mounted to the bottom of a camera. Regardless if it is Mic or Line-level, the CMX-2 gets the job done.
