Connecting the output of a Biamp device to a phantom-powered input
This article describes a method for safely connecting the output of a Biamp Tesira, Audia, Nexia, or Vocia processor to another device with phantom power enabled on its input side.
Biamp Tesira, Audia, Nexia, and Vocia mic/line outputs are not phantom-power tolerant. In order to safely connect them to a phantom-powered input the solution is to capacitively-couple the Tesira/Audia/Nexia/Vocia output to the device.
Schematic and parts
In applications with all Phantom Power voltages up to the full 48-volt standard we recommend the Panasonic ECE-A1HN471U which is DigiKey part number P1287-ND, 470uF @ 50V. These are available in piece quantities.
The diagrams below show how to connect the capacitors.
