Hi all,
Can someone shed some light on this feature in the dbx386 preamp -
"The 376 uses the proprietary Dbx Type IV A-D conversion system, which is designed to extend the headroom for any given digital bit-depth by introducing a non-linear region that affects only high-level signals. In this case, the top 4dB of the dynamic range is made logarithmic rather than linear — so that the further signals push into this region, the more they are squashed. In fact, the log law means that you can never get to the point of digital clipping and, because the logarithmic law mimics tape and tube distortion, it can actually enhance the signal to make it sound more 'analogue'. A further benefit is that, by avoiding clipping, high frequency detail is preserved, albeit in a slightly distorted form, whereas clipping would obliterate it altogether. As Type IV is unclippable, a separate limiter is also unnecessary."
If a preamp doesn't have a feature such as this, what does it mean in simple English?
Cheers
