FetHead Phantom : Serves the required purpose for relatively low gain condenser microphone.

I have a particular condenser microphone that needs a high gain setting on my mixer's preamp, and so has a tendency to cause noise because of the near maximum setting. The FetHead Phantom was the answer because this in-line microphone booster takes its power from the phantom power supplied by the mixer at source and in so doing the FetHead's energised circuits enable about + 18dB further gain to be inserted at the right point. The whole purpose of the device is then achieved because it means the mixer gain rotary switch was advanced to a lesser point than without the FetHead and so noise was eliminated.

The Triton FetHead was cheaper than some rivals and effective for my purposes although no comparisons were made with other makes.
