NNoottee: Remember that the Directed ESP
®
Engine incorporates a digital gain control with
a finite number of adjustment steps (32). A very small adjustment may not cause
any audible changes in output. In addition the range selected may further restrict the
adjustment. Extremely quick, large changes may result in audible artifacts, particu-
larly on low frequency material as the gain is changing more rapidly than the source
electrical wave.
