Switchcraft, Inc., the world's leading manufacturer of interconnect solutions for audio, video and data, has been awarded a US Patent for Phantom Lift, the technology currently incorporated into our 900 Series Instrument Direct Boxes.
The 900 Series, which are geared toward live sound applications, are the world's only direct boxes with a ground lift switch that can be controlled remotely using phantom power from nearly any standard audio console.
In the past, any unwanted noise on a line utilizing a passive direct box meant that someone would have to run on stage to flip the ground lift switch.
Phantom Lift enables the engineer to activate the switch remotely, simply by engaging phantom power on the console.
