A condenser microphone is very good for certain situations. They are excellent at picking up high frequency sounds and provide a very detailed and accurate sound. They are usually used in a studio setting for vocals and musical instruments, or for podcasting. However, they tend to pick up a lot of background noise and need a power source, either from a battery or through phantom power from a mixer or interface.

To calculate the required amps for your PA system, you’ll need to know the total wattage of all the components in your system. Once you have that information, you can use the following formula: amps = watts / volts. Typically, in North America, the household voltage is 120V. So, if your PA system consists of a speaker with a total wattage of 300W, you would calculate it as follows: 300W / 120V = 2.5A. It is a good practice to have a little headroom for your equipment, so you might want to consider a 4-amp circuit for this particular PA system. Please ensure that you consult with a licensed electrician if you are unfamiliar with handling electrical systems.
