avid audio tool, desired level for dialogue
Mixing audio levels in Avid Xpress, or Final Cut Pro can be confusing. If you are mixing for broadcast television keep your levels so they peak somewhere between +6 and +8 on the VU meter side.
If you are mixing for multimedia output, such as a streaming web movie, then you should try and mix your levels to the very top of the scale without exceeding 0 on the digital scale.
Keep in mind that that the Digital scale on the left of the Avid audio tool is only a reference, and is different for each manufacturer. The only important factor is the 0 at the top of the scale. Anything over zero will be useless digital noise. The default setting for Avid is -14 equals 0 VU.
