"The Silent Alchemist is currently live on Kickstarter here: https://www.kickstarter.com/projects/...

In this video, we look at how this power hub, built for musicians and mobile professionals can remove noise caused by ground loops from your setup.

This was recorded by taking the output of the Bastl Dude and connecting it directly into the sound input the camera filming it. (Black Magic Pocket Cinema Camera 4K).

No changes were made to levels on setup or camera.

No post-processing of audio on either Before or After were carried out.
Gain was added within the setup on the Bastl Dude, but this setting was not changed between Before and After shots.

Other than changing the power source (Hub vs Silent Alchemist) no physical changes were made to the setup, other than giving the two pedals their own power connection (in the before setup they share a daisy-chained from the Volca).

The setup comprises of a Korg Volca (9V+) NTS1 (USB-micro), Two pedals, Respira and Avalanche run (9V-), and Bastl Dude mixer (12V +.)."
