JuicedLink affirms that using a 20KHz tone is “evil”, and that their solution is benign.
By introducing the DN101, any of the existing CX family of preamps from JuicedLink can now interface properly with the current audibly-challenged hybrid cameras and defeat their AGC (Automatic Gain Control) in a benign way. We know that the best way to record audio with these cameras is with a separate professional audio recorder. However, there are occasions when there isn’t time to sync separate audio in post (even when you have the help of a wonderful tool like PluralEyes). In those cases, we want the best possible audio available from the camera, even though it certainly won’t be as good as what an independent pro audio recording would be. JuicedLink has always shown a purist engineering attitude, and is known for their tutorial videos which successfully translate audio engineering terms and concepts for the layperson. In one of its latest videos called Tones are evil!, JuicedLink’s president and engineer explains why he believes that his method of defeating the AGC in cameras is superior to 20 KHz tone-based methods used by competitors like Beachtek.
