I've always wondered about this.
My Microphone (Audio Technica 4033) has a 0db/-10 db switch on the back. My ART Tube Pre-amp (which I put before the MOTU and after the Mic) has a +20db switch on the input. My MOTU 828mkII Audio Interface has trim pots for the two mic/guitar inputs which have their own preamps, and the other 8 inputs on the back don't have trim pots, because they don't have preamps. All of the motu's inputs can be +4/-10 switched. Exactly how should I set this up levels wise? d Ce message a été modifié par Dominic Betmead - mar. 8 févr. 2005, 12:28. |

Kind of. It definitely seems that way when you hook it up to a -10 source or destination. Just an additional note to clarify this: +4 is equivalent to 1.228 Volts. Whenever a signal of this strength is input into a device set to +4, it will display 0 on the meters. -10 is equivalent to 0.316 Volts. In a device set to -10 this voltage will display 0 on the meters. It is really that simple, the confusion sets in when the two are mixed. So bottomline: try and keep all devices matched.
Hope this clarifies it. The whole thing is rather technical, but it pays to get your head around it. (Oh no, I am lecturing again...) Kwasi
