BaseAtt‐‐Base Attenuation
Adds a fixed attenuation value, shifting the scale down and allowing attenuation to be
displayed relative to this base level (useful for calibrating signals played over varying
transducers). See "Setting Base Attenuation" on page 14-8, for more information.
StpSize‐‐Step Size
Sets the increments in which attenuation is applied to the signal when using the
Select knob.
Refrnce—Reference
Sets a reference value used to "flip" the scale of the display (useful for displaying
actual signal level on the front panel of the PA5). May be used only when the
intensity of the input signal is known. See "Setting a Reference Value " on
page 14-10, for more information.
Update—Update
Determines whether attenuation changes dynamically as the selector knob is turned or
only after pressing enter to select the current value.
AbsMin‐‐Minimum Attenuation
Sets the minimum level of attenuation the user can apply to the signal (to avoid
accidentally presenting excessively loud signals).
