Triton Audio Phantom Blocker
The Triton Audio Phantom Blocker blocks Phantom power while leaving the audio signal intact.
Phantom power can be applied to either the male or the female side of Phantom Blocker's XLR connector and will not reach the opposing xlr connector, the audio signal travels without restriction in both directions.
Some (older) preamps are sensitive for Phantom power at the input. The preamp's input transformer cannot handle Phantom power from another source. The transformer's thin silk isolations can burn out because a burst of Phantom power switching on creates a high voltage in the input transformer, to prevent this a complete blocking is needed.
Unbalanced TRS to XLR cables
When connecting an unbalanced TRS to XLR cable pin 3 of the XLR connector is directly connected to ground, creating a short, this can damage input transformers and under-dimensioned phantom power circuits.
Balanced device outputs
Phantom blocker is a great solution to protect the output of any device connected to the XLR input of a mixing desk or preamp which has Phantom power switched on, e.g. your computers audio interface.
There are microphones (mainly Ribbon microphones) which do not tolerate Phantom power, to protect your Ribbon microphone against Phantom power we advise FetHead. Connecting a ribbon microphone to a cable which has Phantom power applied sends a rush of current through the microphones transformer, this current gets amplified by the transformer into the primary circuit of the microphone and forces the ribbon out of the magnetic field it is suspended in, this can permanently stretch the ribbon.
