The Juicedlink DN101 works with any existing Juicedlink low-noise preamp. This AGC killer bolts to the side of the preamp and also has a meter, and headphone jack.
The DN101 is still in the infant stage, as you have to cable jump from mixer to preamp to camera. However Juicedlink is working hard to meet the demands of their audience.
Robert, the owner is very accessible and willing to work with customers directly. You can hear him geek it out in the audio clip in the review.
