ART Phantom II Dual Phantom Power Supply

ART Phantom II Dual Phantom Power Adapter
Condenser microphones usually specify different requirements for their phantom power. These ratings can range from 48 Volts all the way down to 9 Volts. Fortunately, there's a certain amount of flexibility with matching Phantom Power voltage to your mic. A rough rule-of-thumb would be 'more is better.'
For example, a 24-volt condenser mic usually works perfectly with a 48 Volt Phantom Power Suppy. Some mics rated at as little as 9 Volts can operate on voltages up to 48 Volts (check with the manufacturer first). Conversely, a mic will generally perform best driven by not less than its rated voltage. So, for a 48 Volt mic, you would get best performance with 48 Volts of Phantom Power. For all the above, check out the Phantom II.
