Protects Your Gear from Phantom Power

If you use condenser microphones, phantom power is a wonderful convenience. For just about everything else, however, it can wreak havoc. Triton Audio Phantom Blocker is aptly named. This handy accessory blocks phantom power, while leaving your audio signal intact. This in-line device can block phantom power on both the male and female sides of its XLR connector, all while permitting your audio signal to travel without restriction in either direction. Our primary use for Phantom Blocker here at Sweetwater is to safeguard our ribbon microphones against damage. That said, it can also protect sensitive vintage mic preamps and balanced device outputs, and it can prevent input transformer damage caused by shorts in unbalanced TRS to XLR cables. Nobody wants to fry their prized vintage ribbon mic (or any of their other gear) with phantom power. That's why you need Phantom Blocker.

Note: Before you connect the device you wish to shield from phantom power, make sure Phantom Blocker is attached to the cable and you have phantom power engaged. Wait five seconds, during which Phantom Blocker's 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.
