Insufficient phantom power voltage may result in compromised performance from our products, particularly if they require the full 48 volts to operate optimally. For some smaller or more affordable mixers that might not output the full 48 volts of phantom power, our standard FetHead operates effectively within a range of 24 to 48 volts. However, our other products require the full 48 volts to function optimally. If you’re encountering issues with insufficient phantom power, using a separate phantom power supply could resolve this problem. This ensures that your FetHead receives the necessary voltage to operate at its best.
