DX8 –
17
The logic functions assigned to each individual
logic input and output are configured using the DX8-
PC application. In addition, each logic input and
output can be assigned a descriptive name (up to
32 characters) for easier identification within the
PC application.
Note:
Logic I/O functions are set from the PC
application only.
Logic Inputs
The following functions can be activated by the
logic inputs:
Force On
Force Off
Input Mute
Output Mute
Group Mute
Preset Recall
Force-on/Force-off
This provides a means to temporarily increase or
decrease the gain of a channel with an external
switch, remote control, or through the priority
function. This is defined in the Audio Input window
in the DX8-PC software application. These are
momentary functions and are active only when the
logic input pin is active (held low). It forces the input
fader level to the
Force On Level
or
Force Off
Level
selected for that channel.
See “Audio In” on page 25 for more information
about the Force-on and Force-off function.
Mute
An input, output, or group can be muted with a
Logic Input. This function can be activated in one of
four ways:
•
Momentary: The mute/enable function is continuously active
while the logic input is continuously active.
•
Latch On: The mute function is activated when the logic input
goes from inactive to active.
•
Latch Off: The mute function is deactivated when the logic input
goes from inactive to active.
•
Toggling: The mute function toggles its state when the logic
input goes from inactive to active.
Preset Recall
This function can be activated as a momentary
function or as a latching function. When activated
as a momentary function, the preset state is
recalled only when the logic input is active. When
the logic input is inactive, the DX8 returns to its
base state as long as no other momentary function
is in force. Normally, the base state is the state the
DX8 was in prior to activating the preset state.
When activated as a latching function, the
preset state is recalled when the logic input goes
from inactive to active. See “Presets” on pages
22 and 29 for more information about the preset
recall function.
Logic Outputs
The logic outputs indicate the state of the following
conditions, selectable in software:
Input Signal Present
Output Signal Present
Input Channel Open
Output Channel Open
Preset Active
Priority Inactive
Auto-gate Status
Signal Present
A logic output can indicate whether a signal greater
than –40 dBFS is present on an input or an output.
Select the channel from the DX8-PC application.
Channel Open
A logic output can indicate when a channel or mix
output gain is greater than –40 dBFS. For an input,
this includes either the Bus A or B mix level. For the
output, it is either the A or B mix output. Select the
channel from the DX8-PC application.
Preset Active
A logic output can indicate when a particular preset
is active. Choose the preset indicated by the logic
output from the DX8-PC application.
Priority Inactive
A logic output can indicate whether an Input
Force-on Priority is active, as selected from the
DX8-PC application.
Auto-gate Status
A logic output can indicate when an Input Gate is
active. Auto-gate is selected in the Automix window
(see "Automix" on page 24 for more information
about the Auto-gate function).
