To access the UserOps menu:
Turn the
Select
knob until
UserOps
appears on the display.
Press and release the
Select
knob.
Set the
UserOps
parameters as desired.
To set parameters such as step size ( StpSize ), update mode ( Update ), minimum
attenuation ( AbsMin ), base attenuation ( BaseAtt ), and reference value ( Refrnce ); turn the
Select
knob to the desired value and then press and release to save changes.
To exit any menu without saving parameter changes, press and release the
ESC
button
before the settings are saved.
About UserAtten Mode Parameters
In
UserAtten
Mode, the user may set parameters such as step size (
StpSize
), update mode
(
Update
), and minimum attenuation (
AbsMin
). The scale can be adjusted using the base
attenuation (
BaseAtt
) and reference value (
Refrnce
) parameters. Both base attenuation and
reference can be used simultaneously, producing an actual attenuation equal to (
Refrnce
+
BaseAtt
-
{dial setting}
). See
for more information.
BaseAtt - Base Attenuation
Adds a
fi
xed 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
, 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 "
fl
ip" 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
for more information.
