So if our amplifier has a gain of 28dB, we find that our amplifier is boosting the input from the preamplifier by a factor of 10^ (28/20) or ~25.1. meath.ie speed limits

First of all, lets address what a mic preamp actually does. A mic preamp, short for microphone pre-amplifier, is a device which is used to amplify the level of a microphone signal from mic level to line level. The level of the signal which a microphone produces is very low. WebIn a home theatre system, the pre-amplifier performs two main functions: it handles switching between different line level sources and boosts the signal before sending it to the amplifier. A weak electrical signal becomes strong enough for additional processing, preventing noise and offering cleaner output. peggy hall curci
