Manufacturer's Description
Low THD phantom power supply
True Phantom is a dual channel P48 Phantom power supply. Compared to traditional phantom power supplies, True Phantom achieves lower distortion and an improvement of the signal-to-noise ratio. Based on patented technology True Phantom enables unparalleled performance from your microphone.
The only real update on the now standard phantom powering scheme, the advantages of our True Phantom are easily heard and will work with all phantom powered microphones. True Phantom does not affect the frequency response of the microphone but lowers the microphone’s output THD significantly. Literally a breath of fresh air.
Circuit topology
For powering condenser microphones, the IEC 61938 phantom power supply has been the standard for decades. Although being proven technology, there are several disadvantages to the current implementation. The microphone signal, for instance is not completely available to the microphone preamp. A 6K8 resistor presents a load to the microphone's circuit. This causes distortion and reduces the available signal. Also, with the IEC 61938 phantom power implementation, isolation from the rest of the preamp or mixer circuit is not complete, this can negatively affect noise performance.
True Phantom uses patented technology which overcomes these problems. Our circuit consists of a low noise internal power supply which powers an active, low noise P48 phantom power circuit. True Phantom's electronics enables the microphone to operate at no-load condition, which lowers distortion and improves noise performance compared to the current implementation.
