Different condenser microphones specify different amounts of phantom power required. Typically, these voltage ratings can vary from 48 volts up to 9 volts. Fortunately, there is some flexibility in terms of matching the phantom voltage to your mic. A rule of thumb would be "the more, the better".
For example, a 24 volt condenser mic will work just fine on 48 volts. In fact, pickups as low as 9 volts can often operate on 48 volts, but you should check with the manufacturer first. Conversely, a mic will generally perform best if driven by a voltage no lower than its rated voltage, so for a 48V mic you'll get the best results with 48 volts of phantom power. The Phantom I is an excellent choice for the above needs.
