Here's an example with one camera and one set of #Juicedlink DARs. You can expand to several more DARs if you are working with multiple subjects, or split up to 'groups' of DARs if you are working with multiple camera angles. By customizing the Config file in each DAR you can control all types of functions including start and stop recorders remotely, audible slate, vibrating slate with LED indicators, amount of slate tones, etc. Lots of cool stuff you can do with these recorders! These DARs also record two tracks (one attenuated safety backup track), in case your volume peaks out.
Showing a basic setup with the JuicedLink DAR recorders. You can use it on your talent when Wireless is not a good option, and it even offers a remote Slate feature for faster audio sync in post. https://Juicedlink.com
