Programmable Output Status “LED” -
Shows the current state of a programmable output. If the programmable output
function is set to “Channel Activity”, the LED will light any time any of the associated input channel(s) are active. If the
programmable output function is set to “Programmable Input State”, LED activity should be interpreted using the
information below:
Function
State when LED On
State when LED Off
Analog In Control
Attenuation < 15dB
Attenuation > 15dB
Increase In 1dB:
Contact closure on prog input
No contact closure on prog input
Decrease In 1dB:
Contact closure on prog input
No contact closure on prog input
Analog Out Control
Attenuation < 15dB
Attenuation > 15dB
Increase Out 1dB:
Contact closure on prog input
No contact closure on prog input
Decrease Out 1dB:
Contact closure on prog input
No contact closure on prog input
Memory Preset:
Associated memory is active
Associated memory is not active
Toggle Crosspoint Gain:
Input-to-output(s) connection made
Input - output(s) connection not made
Mute In:
Associated input(s) not muted
Associated input(s) muted
Mute Out:
Associated output(s) not muted
Associated output(s) muted
Apply Button -
Applies the current setting of “Function” and “Applies To” to the current programmable output. When the
Apply button is enabled, this indicates that the setting of “Function” and “Applies To” in the AS16x12 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 AS16x12 setup. This does not store the changes to a memory preset! That must be done
explicitly from the File/Save Active to AS16x12 Preset... file menu option. If changes are made to a programmable output
but not applied (by clicking on the Apply button), and another programmable output is selected (by clicking on of the Select
Programmable Output buttons), all the changes to the first programmable output which were not applied will be lost.

Channel Activity -
Allows the selected
programmable output to indicate activity
on one or more input channels. Anytime at
least one of the inputs associated with a
particular programmable output is active,
the programmable output will be active.
This is useful for initiating activities which
must react to activity on specific channels.
One example is video-follow-audio, where
d i ff e rent cameras (or camera positions)
must be activated based on channel
activity. Note that on the Misc Settings tab, the input qualification time and output hold time may be set to optimize the
time response of channel activity for various applications. The screen below shows programmable output 1 responding to
activity on any of input channels 1, 2, or 3.
Programmable Input State -
Allows the selected programmable output to indicate the current state of one of the
programmable inputs. This is particularly useful when you need to supply user feedback for the state of a bistate
programmable input. The programmable output may then be connected to a LED to show the state of the associated
programmable input.
When the room combining capability of the AS16x12 is used, a logic output will automatically be associated with each
Toggle Room Boundary programmable input. This will provide user feedback as to the combine status of each boundary
between two rooms. You’ll notice that the frame caption changes to include the phrase “(used for room combining)” as a
reminder that this programmable output cannot be changed in this tab.
A programmable output whose function is Programmable Input State will be active (i.e. conducting to ground) or inactive
(i.e. open) as follows depending on the function of the programmable input with which it is associated:
