12 – DX810
The logic functions assigned to each individual
logic input and output are configured using the DX-
810-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/Enable

Output Mute/Enable

Group Mute/Enable

Preset Recall

Combine On

Force-on/Force-off
This provides a means to temporarily increase or
decrease the gain of an input channel or group with
an external switch, remote control, or through the
priority function. This is defined in the Force
Control window in the DX-810-PC software
application. It forces the input fader level to the
Force On Level or Force Off Level selected for that
channel (relative to the current setting). It forces the
group fader level (when selected under Affected I/O
in the Logic Input window) to its current fader level
(Force On) or completely off (Force Off). See “Force
Ctrl” on page 19 for more information about the
Force-on and Force-off function.
This function can be activated in one of four
ways, and is active when the logic input pin is
active (held low):
•Momentary: The force function is continuously
active while the logic input is continuously active.
•Latch On: The force function is activated when the
logic input goes from inactive to active.
•Latch Off: The force function is deactivated when
the logic input goes from inactive to active.
•Toggling: The force function toggles its state when
the logic input goes from inactive and active.
Mute/Enable
An input, output, or group can be muted or enabled
with a Logic Input (see page 28 for information on
changing between mute or enable operation). 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/enable function is activated
when the logic input goes from inactive to active.
•Latch Off: The mute/enable function is deactivated
when the logic input goes from inactive to active.
•Toggling: The mute/enable function toggles its
state when the logic input goes from inactive and
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 DX810 returns to its
base state as long as no other momentary function
is in force. Normally, the base state is the state the
DX810 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 page 18 for
more information about the preset recall function.
Combine
This function can be activated as a momentary
function, a latching function, or a toggling function.
When activated as a momentary function, the
selected combination is activated only when the
logic input is active. When the logic input is inactive,
the combination is deactivated.
When activated as a latching function, the
combination is activated when the logic input goes
from inactive to active (Latch On), or the
combination turns off when the logic input goes
from inactive to active (Latch Off).
When activated as a toggling function, the
combine state changes from its current state when
the logic input goes from inactive to active.
See “Combine” on page 21 for more information
about the room combining function.
Logic Outputs
The logic outputs indicate the state of the following
conditions, selectable in software:

Input Mute/Enable

Output Mute/Enable

Group Mute/Enable

Output Signal Present

Preset Active

Force On Active

Priority Active

Combine Active

Gate Status

Mute/Enable
A logic output can indicate when the mute or
enable for a particular input, output, or group is
active. See page 28 for information on changing
between mute or enable operation.
Output Signal Present
A logic output can indicate when a signal greater
than –40 dBFS is present on an output.
