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.
Important
Before you connect the device you wish to shield from phantom power, make sure your phantom
blocker is attached to the cable and have phantom power engaged.
Wait 5 seconds, during which phantom blockers internal bleeder resistors will cancel out voltage
differences. Connecting in this order prevents the transfer of an initial AC voltage burst created
by the phantom power switching on.
Recommended applications
• Microphones
There are microphones (mainly ribbon microphones) which do not tolerate phantom power.
Connecting a ribbon microphone to a cable which has phantom power applied sends a rush of
current through the microphone’s 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. We advise to use our FetHead to add
clean gain and protect your ribbon microphone against phantom power.
• Microphone preamps
Some (vintage) 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
Our 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.
