Specification Overview:
The Demux 24 is a 24 channel DMX to analogue
converter, housed in a compact 1U 19” rack
mounting case.
The Demux24 is well specified, featuring four ring
locking DIN output connectors (each carrying six
channels), preheat and 3 output laws selectable per
channel, positive / negative polarity and DMX
address selectable per output socket, and manual
level control plus 12 memories for standalone
operation. Remote operation is possible by DMX,
with optional end-of-line termination.
Control Interface
The main display consists of four seven-segment
displays; the data displayed is dependent on the set-
up mode of the Demux 24. Around the outside of
these displays are eight LED’s. Seven of which
indicate the current set-up mode of the Demux 24,
the eighth is used for DMX indication.
The Demux 24 has a default mode, for operation. In
this mode none of the set-up mode LED’s will be lit,
the main display will show the DMX address(es) and
if it has been terminated a small dot will be shown in
the bottom right of the fourth display.
Mode Button:
The Mode button is used to cycle through the
different set-up modes. They are;
- Manual
- DMX address
- DMX fail
- Memory
- Preheat
- Law
- Polarity

Enter Button:
The Enter button is used to confirm actions.
Up & Down Buttons:
These are used to adjust the values shown in the
main display. Pressing both buttons together will
reset the display to the default values.
Set-up Modes:
Manual Control:
The Manual Control Mode allows the user to set-up a
look on the outputs without the need of an external
controller.
Select
‘Manual’
mode using the ‘Mode’ button. The
display will show CC.LL, where CC is the channel
number and LL is the level. Select the channel you
require or ‘A’ for all channels, using the ‘Up & Down’
Arrows and press ‘Enter’. Now set the level you
require using the ‘Up & Down’ Arrows and press
‘Enter’ again to confirm and move back to the
channel selection.
DMX Address:
There are 2 ways that the Demux 24 can be patched
– a single DMX start address can be set for the block
of 24 channels (block patch), or each output socket
(6 channels) can be given a different DMX start
address.
For block patch, the range of DMX start addresses is
001 – 489. In default mode the single DMX start
address of the block will be shown on the display.
For individual patch, the range of DMX start
addresses is 001 – 507. In default mode all four DMX
start addresses are cycled on the display.
Select
‘DMX ADDRESS’
using the ‘Mode’ button, the
display will show S.AAA, where S is the socket
number and AAA is the current DMX address for that
socket. Select the socket you require (1-4), or ‘A’ for
all sockets (block patch), using the ‘Up & Down’
Arrows and press ‘Enter’. Now set the address you
require using the ‘Up & Down’ Arrows and press
‘Enter’ again to confirm and move back to the socket
selection.
DMX Fail:
There are three DMX fail modes available – ‘fade to
black’, ‘hold DMX’ and ‘fade to memory’.
Select ‘
DMX Fail’
using the ‘Mode’ button. Using the
‘Up & Down’ Arrows select your preferred choice
