You need line inputs for synthesizers, drum machines and other equipment with a medium to high output level. Obviously, you don’t need those to make microphone recordings, but they’re very useful to have.

Additional inputs for line signals and instrument signals.

Also, phantom power does not affect dynamic microphones that do not require external power. The beauty of this solution (a Neumann invention) is that it does not require any additional leads but uses normal XLR cables. This is a way of powering condenser microphones from the microphone input.

Phantom power (often labeled “P48” or “48V”).At least one XLR microphone input for stereo recordings you obviously need two.Good ones, which offer superior sound and better quality overall, start at about 400-500 dollars/euros. Stay away from the cheapest models 200 dollars/euros is about the minimum for a decent audio interface. You won’t find them in most computer stores, but you can buy them online or locally from any retailer of musical instruments. These devices are called audio interfaces and are offered by numerous manufacturers. Luckily, there are devices that cover all of those requirements, and then some.
