There shouldn't be any level change due to the s/pdif connection. If you can mix down to a
24 bit file within the AW2400 then it would be best to increase the level of that file
inside the AW2400 after the mixdown. If you can't save to 24 bit files you will need to
adjust the master level on the AW2400 as you mix to ensure that you have a reasonable
level on the CD. When mixing to a 16 bit medium like DAT or CD I always try to have peaks
no lower than -6dBFS (but NEVER over 0dBFS).
