Lectrosonics AM16/12 Operating Instructions Manual page 17

AM16/12 setup. Note that you should use the Select Programmable Input buttons to select the programmable input you'd
like to configure before doing any configuration.
Select Programmable Input Buttons 1-17 - Allows selection of which programmable input to change. Note that the
frame caption "Programmable Input ..." (upper left in blue) will change to indicate the programmable input 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 programmable input. Note
that the caption on the Push Input button always reflects the current programmable input. The Push Input button will be
disabled for the Analog In Control, Analog Out Control and Not Used options.
Programmable Input Status "LED" - Shows the current state of a programmable input. The status indicator only has
meaning for the following programmable input functions:
Function
Analog In Control
Increase In 1dB:
Decrease In 1dB:
Analog Out Control
Increase Out 1dB:
Decrease Out 1dB:
Memory Preset:
Toggle Crosspoint Gain:
Mute In:
Mute Out:
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 AM16/12 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 AM16/12 setup. This does not store the changes to a memory preset! That must be done
explicitly from the File/Save Active to AM16/12 Preset... file menu option. If changes are made to a programmable input
but not applied (by clicking on the Apply button), and another programmable input is selected (by clicking another 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 program­
mable 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 Control 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 In mode is 0VDC to 5VDC.
0VDC corresponds to "Off" (or Rear
Panel Minimum Input Gain, if it is
programmed for less attenuation
than "Off"), and +5VDC corresponds
to 0dB. In addition, a SPST toggle
switch may be used as a mute
switch. Connect the two switch
contacts to the programmable input pin and ground. The inputs will be muted when the contacts are closed. The screen
shown to the right indicates that the function of programmable input 1 is analog input control of inputs 1, 2, 3, 5, and
7. Notice how multiple inputs may be controlled by a single programmable input.
