Low THD P48 Phantom Power Supply
- Lowers THD on condenser microphones
- Or any other phantom powered device
- Your microphone never sounded better
The only real update on the now standard Phantom powering scheme, the advantages of this True Phantom are easily heard and will work with all Phantom powered microphones. Literally “a breath of fresh air” when used with any such microphone. True Phantom does not affect the frequency response of the microphone but lowers the mic output’s THD significantly.
For powering condenser microphones, the IEC 61938 Phantom Power supply has been the standard for years. Although being proven technology, there are several disadvantages to the current implementation. The microphone signal, for instance is not completely available to the microphone pre-amplifier. To the microphone’s circuit, the 6.8kΩ resistor presents a load, this causes distortion and reduces the available signal level. 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. True Phantom’s electronics enable the microphone to operate at a no-load condition, which lowers distortion; compared to the current implementation it achieves lower distortion and an increase of the signal-to-noise ratio.
- Dual channel for stereo recording
- XLR inputs and outputs
- Power ON indicator (True Phantom logo)
- Ground lift switch
- Built-in High end Phantom blocking circuit for use with sound cards and unbalanced inputs
- Direct switch, bypasses the Phantom Blocking circuit for professional equipment (that already have blocking capacitors)
True Phantom is engineered for the lowest noise and distortion by utilising a low-noise power supply circuit which powers an active low-noise phantom power circuit. True Phantom’s patented electronics enable the microphone to operate in a no-load condition; this lowers the distortion and improves the noise performance.
Rear switches are included for Ground Lift and “Direct” connection. True Phantom is delivered with ground connected and with DC blocking capacitors connected to the output. This blocks the phantom power from entering following equipment. However, most professional balanced microphone inputs already have blocking capacitors in the circuit – in this instance pressing the “Direct” switch by-passes the blocking capacitors in the True Phantom which enables higher quality by removing the DC block in the True Phantom, leaving a single DC block in the following equipment (NB: for recorders with an unbalanced microphone input and for computer sound cards, the DC block in the True Phantom should be left in the factory setting).
