TritonAudio Phantom Blocker

Bol Partner

Phantom blocker blocks phantom power while leaving the audio signal intact. Phantom powercan be applied to either the male or the female side of phantom blocker's XLR connector and willnot reach the opposing XLR connector, the audio signal travels without restriction in bothdirections.ImportantBefore you connect the device you wish to shield from phantom power, make sure your phantomblocker is attached to the cable and have phantom power engaged.Wait 5 seconds, during which phantom blockers internal bleeder resistors will cancel out voltagedifferences. Connecting in this order prevents the transfer of an initial AC voltage burst createdby the phantom power switching on.Recommended applications• MicrophonesThere 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 ofcurrent through the microphone’s transformer, this current gets amplified by the transformerinto the primary circuit of the microphone and forces the ribbon out of the magnetic field it issuspended in, this can permanently stretch the ribbon. We advise to use our FetHead to addclean gain and protect your ribbon microphone against phantom power.• Microphone preampsSome (vintage) preamps are sensitive for phantom power at the input. The preamp's inputtransformer cannot handle phantom power from another source. The transformer's thin silkisolations can burn out because a burst of phantom power switching on creates a high voltage inthe input transformer. To prevent this a complete blocking is needed.• Unbalanced TRS to XLR cablesWhen connecting an unbalanced TRS to XLR cable, pin 3 of the XLR connector is directlyconnected to ground, creating a short, this can damage input transformers and underdimensioned phantom power circuits.• Balanced device outputsOur phantom blocker is a great solution to protect the output of any device connected to theXLR input of a mixing desk or preamp which has phantom power switched on, e.g. yourcomputers audio interface.
