With the Rode DCS-1, you can easily attach 2 devices at the same time to a single cold shoe connector of your camera. This way, you can place 2 wireless receivers on your camera, which is useful if you interview 2 people. You can attach both a microphone and a receiver to your camera. For example, if you record sound from up close with a fixed microphone and someone's talking in the distance with a wireless microphone at the same time. Thanks to the cable management slots, you can neatly conceal the cables and they won't block the image.
