By neutral I mean that the pre-amplifiers are designed so that they change the frequency content of the incoming signal as little as possible in the amplification process. A signal with such low amplitude is unusable practically.ДЄ Neve 1073 8 Microphone Pre-Amplifier Rack.ДЄudio interface pre-amplifiers are generally designed to be as neutral as possible. 1.85 mV is a low amplitude for a signal and a pre-amplifier must be used to boost this signal to a level proper for recording or live performance. For example the most popular dynamic microphone around, the Sure SM58 has a rated sensitivity of 1.85 mV for a sound pressure level of 94 dB (1 Pa). The pre-amplifier is an electrical circuit that is designed to boost the amplitude of a very low signal, such as the signal coming from a microphone to a level that makes the signal usable. These devices are so good nowadays some products have amazing A/D converters comparable to high-end standalone converters, close to zero monitoring latency, high input and output count but how do the preamps of todayвЂ™s audio interfaces match up to outboard pre-amps? Is there even a comparison between these two categories of products? In this article, we will look at a few products and try to answer which product out there has the best pre-amps and how much that actually matters.

They serve as an input and output device, A/D converter, pre-amplification, monitoring and some of them even offer processing capabilities вЂ“ a studio in a little box.

Audio interfaces are a sum of parts that act like a Swiss army knife/ multi-tool in more and more home and project studios.
