too fast and still have the quick response of the VCA needed to tame transient
signals. This essentially means that AutoVelocity™ Dynamic circuitry creates a
fast “peak limiting” function which rides on top of a slower “compression”
function.
AutoVelocity™ Dynamics is now available on all dbx 160SL units
manufactured after January 1, 1998. A retrofit kit is available so that any dbx
160S can be updated to include this new technology. One might ask how this
retrofit kit affects the manual attack and release settings that were modeled
after the 165/165A. Die-hard fans of this sound, of course, would not want to
give up the sound they know and love for a different one. No problem, just
remove the lid of the 160S and depress a push-push type switch to disengage
the AVD circuitry in each channel, and instantly the original attack and release
characteristics of the 165/165A are restored giving the user ultimate flexibility
in compression needs. Instructions to do this are included in the manual for
new units and in the retrofit kit instructions for the existing units.
Figure 1. The graph on left shows the small step attack curve of the 160SL in response to a sine
wave burst input with AVD circuitry disengaged. The graph on the right shows the attack curve of
the 160SL to the same burst input with AVD circuitry engaged. Note the slower attack time in the
graph on the right.
