[QUOTE="Robert Lofgren, post: 108609, member: 2447"] Re: X32 Discussion On any device that uses 0dBFS as the metering level you must ensure that you never hit zero. The reason being that when the level is that hot the a/d-converters becomes overloaded and distorts in a bad way. Analog devices tends to smooth this distortion over a range and many times that distortion is much more pleasing to the ear. For technical reasons (google is your friend) the reference level called 0dB on an analog metering scale is considered to be -18dBFS on your digital device. Depending on where you come from this reference level can change somewhat. As on an analog meter where you aim your audio level to be around 0dB you do the same in the digital world but using -18dBFS instead. This leaves you with 18dB of headroom before digital clipping. If your program material is highly dynamic you may want to aim for -24dBFS instead. Unlike analoge consoles you must never let the clip-light turn on. This will get you into nasty digital distortion territory! I have seen many analog guys drive digital desk into clipping and say this is fine. It isn't! Only on some consoles (midas) where the clip light represents analog preamp distortion long before digital distortion. The x32 analog preamp never distorts before the digital distortion... [/QUOTE]
