The Whirlwind MicPower 2 phantom power supply gives you an affordable, portable way to use high-quality condenser microphones with nonpowered recorders and mixers. If your recording interface or small-format mixer lacks its own phantom power source, just plug into the Whirlwind MicPower 2 and give up to two of your condenser mics the true 48V phantom power they need. The MicPower 2 runs for hours on four AA batteries, or you can use its included AC adapter. Either way, the MicPower 2 will provide your microphones with ultra-quiet, reliable 48V phantom power.
