User Tips
- Users have reported that both 48V and 12V output voltages are accurate and the device adds no noticeable noise to the signal.
- For users seeking additional gain and an even better signal-to-noise ratio, combining this phantom power supply with an external FET preamp (around 18 dBs of gain) can yield excellent results.
- While a 'Bass mode' is available, some users may find the 'Normal mode' more suitable for general microphone use. Experiment to find the best setting for your specific microphone and audio needs.
- The device features a robust metal casing, providing good durability and shock resistance.
