ART constructed the Phantom I Active Direct Box to serve a multitude of needs in the studio and onstage: <BR><BR>Problem: You need to connect an amplifier's speaker output to the mic input on a mixer.<BR><BR>Solution: Connect a Phantom I between the speaker output and a mic input with phantom power on the mixer, then set the attenuation switch to 40dB.<BR><BR>Problem: Your PA is humming because there is a ground loop between a signal source and the mixer.<BR><BR>Solution: Connect a Phantom I between the signal source and a mic input with phantom power and set the ground switch to Lift. <BR><BR>Problem: You need to connect an unbalanced line-level source (i.e., a synthesizer, another mixer, an effects device, etc.) to a mic input on the mixer. <BR><BR>Solution: Connect a Phantom I between the source and a mic input with phantom power and set the Attenuator switch to 20dB.<BR><BR><em>The Phantom I is not a phantom power supply, it is an active direct box that operates on phantom power.</em>
