Please compare to the specs of a real mic preamp, please, for example: http://www.rme-audio.com/english/micpreamps/quadmic.htm (which would be an appropriate companion to the multiface) In particular: "Amplification can be set between 10 and 60 dB". 60dB of gain expressed as a voltage ratio would be amplifying the signal by 1000. I would imagine you would need to use 40 to 60dB to amplify a mic to line level so you are at least a factor of 10 below what would be needed. > It is sold by B&K and they swear by it. (they can swear all they want but that's not gonna make it amplify the signal more :-) The key here (as outlined before in the thread) is gain. This signal conditioner's gain is too low (probably by a factor of at least 10) to act as a mic preamp _unless_ your line input has additional gain you can dial in (which is probably why you can use it with other equipment). -- Fernando > Paul Winkler wrote: > > On Sat, May 13, 2006 at 04:16:28AM +1000, D.
