Just how important is a pre amp?? My band is currently using a Behringer Eurorack 12 channel mixer, which has built in mic pre amps...my drummer/producer says the built in pre amps are not the highest quality and that its the reason we are not getting where we want to with out recording...will a good outboard pre amp make a big difference in the recording process? We are looking into the ones seen here - http://www.music123.com/search/?src=focusrite http://www.music123.com/Mackie-ONYX-800R-8-channel-microphone-preamp-i153358.music We were just gonna buy a better mixer with better built in mic pre amps, but we decided to get an outboard pre amp.. Will pre amps (such as the ones seen in the links) make a big difference? Our budget is $1000 (Canadian)...can we get a good pre amp for this? We are looking into one with 8 inputs.. Please give us some advice...we dont wanna waste our money.. Thanks!
