Why does UltraSound use only 15v phantom power rather than the 48V?

The main reason we use the DIN 45-596-P12 standard is because it is much less likely to harm your equipment. 48v phantom has been known to cause harm to some equipment that is plugged into it. Given that only a very few "boutique" externally biased condenser mics actually need 48v phantom power we feel it is not worth the risk and expense.

Below is an excerpt from our owners manual which has a list of condenser mics which will work very well with our amps. ** PHANTOM POWER - An internal phantom power source (13.6 volts) is provided for use with condenser mics. This power source is on at all times and does not affect the standard operation of the amp, even when a condenser mic is not used.

We use the DIN 45-596-P12 volt standard which will operate virtually all of the live sound reinforcement condenser microphones on the market. Some "boutique" externally biased condenser mics will not be compatible and will require 48 volt phantom power. We suggest live sound condenser mics by: AKG ( ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
