AutoVelocity™ Dynamics and the dbx 160SL

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.
