- Yes. The biggest advantage of the old 3BX was that you could
- separately compand the bass midrange and treble. This was
- great for avoiding woofer damage, yet preserving the impact of
- rim shots.
-
- The Sony TA series digital preamps include both compression and
- expansion, done digitally. The implementation is less than
- optimal in that it is global across the frequency band rather
- than possibly being tied to the parametric EQ. It also doesn't
- allow separate adjustment of the slicing level and compansion.
- Unjudicious use can easily drive the preamp into digital
- clipping with truly horrid results.
-
- However, used judiciously, mild compression can create the
- illusion of "more information" on those CD's which have been
- recorded with no compression or gain riding...and help avoid
- clipping on wimpy amplifier/speaker combinations. The other
- advantage is that if your equipment can tolerate it, you can
- expand the dynamic range of tapes, LP's and AAD disks.
