select different functions. All other parameters are disabled. This eliminates invalid Function/Applies To settings.
Each of the available functions is explained below.
Hint : If the function (or any associated inputs, outputs, etc.) of a programmable I/O is changed on the control panel,
the Apply button will be enabled. The Apply button is located in the lower right hand corner of the Programmable I/O
tab. The Apply button must be clicked before any changes are actually applied to the active AM8/4 setup. Note that
you should use the Select Programmable Input Radio Buttons to select the programmable input you'd like to config-
ure before doing any configuration.
Select Programmable Input Radio Buttons 1-13 - Allows selection of which programmable I/O to change. Note
that the frame caption "Programmable Input ..." (upper left in blue) will change to indicate the programmable I/O
currently being changed.
Push Input Button - Allows a contact closure to be simulated for the current programmable input. This is useful
when testing to see that the changes you've made to each programmable input indeed have the intended effect.
Each click on the "Push Input..." button has the same effect as a momentary contact closure on the current program-
mable input. Note that the caption on the Push Input button always reflects the current programmable input. The
Push Input button will be disabled for any programmable inputs which are "Not Used", "Analog In" control, or "Analog
Out" control.
Programmable I/O Status "LED" - Shows the current state of a programmable I/O. The status indicator only has
meaning for the following programmable input functions:
Analog In:
Increase In 1dB:
Decrease In 1dB:
Analog Out:
Increase Out 1dB:
Decrease Out 1dB:
Preset Recall:
Toggle Crosspoint Gain LED ON - Selected input is sent to outputs LED OFF - Selected input not sent to outputs
Mute In:
Mute Out:
Programmable Output:
Apply Button - Applies the current setting of "Function" and "Applies To" to the current programmable input. When
the Apply button is enabled, this indicates that the setting of "Function" and "Applies To" in the AM8/4 does not match
the setting of "Function" and "Applies To" shown on the control panel screen. Clicking the Apply button will load the
control panel setting into the active AM8/4 setup. This does not store the changes to a memory preset! That must
be done explicitly from the File/Save Active to AM16 Preset... file menu option. If changes are made to a program-
mable input but not applied (by clicking on the Apply button), and another programmable input is selected (by clicking
on of the Select Programmable Input buttons), all the changes to the first programmable input which were not
applied will be lost.
Programmable Input Functions :
Analog In Control - Allows one or
more input gains to be controlled by an
analog voltage on a programmable
input pin. Analog input gain control
goes from a maximum of 0dB gain to a
minimum of 30dB attenuation, plus
"Off". The gain change resolution is
1dB. The analog in mode is ideal for
using a pot (or some other source of
analog voltage) to control input gain.
The valid voltage range in the analog
input mode is 0VDC to 5VDC. 0VDC
corresponds to "Off" (or Rear Panel
