DX8 – 17
Logic Inputs
A number of functions can be activated by the
logic inputs:
Force-on/Force-off
This provides a means to temporarily increase or
decrease the gain of a channel with an external
switch. These are momentary functions and are
active only when the logic input pin is active (held
low). It affects a single input (only if the selected
input has no priority assigned), which is defined
when configured in the DX8-PC software
application, and forces the input fader level to the
fader on level or fader off level selected for that
channel. See “Audio In” on page 27 for more
information about the Force-on and Force-off function.
Mute
This function can be activated in one of three
ways:
1. Momentary, where the mute function is
continuously active while the logic input is
continuously active.
2. Latching, where the mute function is activated or
deactivated (as specified during configuration)
when the logic input goes from inactive to active.
3. Toggling, where the mute function will toggle its
state when the logic input toggles between
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 (1-16
states, defined when configured) is recalled only
when the logic input is active. When the logic input
is inactive, the DX8 returns to its base state
(normally, the state it was in prior to activating the
preset state), as long as no other momentary
function is in force.
When activated as a latching function, the
preset state is recalled when the logic input goes
from inactive to active. See “Presets” on pages
19 and 21 for more information about the preset
recall function.
Logic Outputs
The logic outputs indicate the state of a number
of different conditions.
Signal Present
A logic output can indicate whether a signal
greater than –40 dB 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 dB. 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.
Front Panel Lock
The MODE button on the front panel is used to
disable the front panel controls by selecting LOCK.
The LOCK LED blinks for about five seconds before
it engages. When the LED lights steadily, the front
panel controls are disabled.
The Lock Code is set using the DX8-PC
application (see page 20, "Set Lock Code"). To
unlock the DX8 from the front panel, press the
bottom "Down" buttons on the front panel in the
correct numerical sequence, according to the
following chart:
Input 1 Down = 1
Input 2 Down = 2
Input 3 Down = 3
Input 4 Down = 4
Input 5 Down = 5
Input 6 Down = 6
Input 7 Down = 7
Input 8 Down = 8
Low EQ Down = 9
Hi EQ Down = 0
Note: The default Lock Code is "1234."
Upgrading the Software
From time to time, Mackie Industrial will
release upgrades for the internal operating
software in the DX8. This can be downloaded
from our website (
www.mackieindustrial.com ) to a
PC-compatible computer. Use the serial port on
the computer to connect to the COMM PORT on
the DX8 to transfer the data to the on-board flash
memory with the DX8-PC software.
