Logic Outputs
Principle of Operation
The DX1208 has three Logic Outputs which indicate various hardware conditions. The Logic
Outputs are open-collector outputs that are pulled high internally to +5V through a 340 ohm
resistor. They can sink up to 12 mA of current and drive an LED directly.
Logic Outputs can be set active high (4.8V, unloaded) or active low (0.4V, unloaded). When a
Logic Output is inactive, the output is set to the opposite logic level. This is also true when the
output Enable is unchecked or the Function is set to [None]. So, for example, if Function is
set to [None] and Active is set to [Low], then the output will be high.

State

Active
[Preset]
Recalls the preset number chosen in the associated
Select setting.
[Priority]
Triggers the ducker Priority level chosen in the
associated Select setting.
[Mute All In] Mutes and unmutes all Analog, Digital, and DX Link
Inputs.
[Mute All Out] Mutes and unmutes all Analog and DX Link
Outputs.
[Mute Ch]
Mutes and unmutes only the Input, Output, or DX
Link channel chosen in the associated Select setting.
Assigns a specific Preset, Priority level, or input/output channel
number to the [Preset], [Priority] or [Mute Ch] Function.
Each Logic Output can be given a Name to identify its function or
location.
When Enable is checked, then when condition defined by the
Function setting occurs, the Logic Output becomes active.
This indicator lights when the Logic Output is active, and is dim
when inactive.
Active defines the logic level of the output when the output is
active.
[Low]
When [Low], the Logic Output level is +0.4V
(unloaded).
