0VU is calibrated to a nominal operating level of +4dBu. Which in turn is relative to a typical EBU

calibration of +18dBu = 0 dBFS. 0 dBFS is your absolute maximum digital level (full scale) and

should be avoided at all costs - digital clipping is not a pleasant sound.

As such the bargraph meter scale on ASP4816 is calibrated in dBFS, such that +4 dBu = 0VU = -14

dBFS. Therefore, a nominal

operating level of 0VU will result in 14 dB of headroom in your digital recording platform (providing

your AD/DA converters are aligned to 0 dBFS = +18 dBu.

14 dB of headroom is very useful as most music sources (except for the huge dynamic range of an or-

chestra) have crest factors (the difference between average (RMS) and peak level) of around 12-20 dB.

ASP4816 therefore provides ample headroom for your beautifully crisp transient sources.
