DX1208 – 3
2. INTRODUCTION
The DX1208 is a 12-input, 8-output DSP matrix mixer
designed for use in a variety of commercial and installed
sound applications such as churches, courtrooms, convention
centers, and hotels. Eight inputs are mic/line capable, with
selectable 48-volt phantom power provided for each input.
These 8 inputs and the 8 outputs are accessed using Euroblock
detachable connectors. Four additional inputs on unbalanced
RCA connectors allow the user to “stack” inputs (inputs 5-8),
increasing the number of audio sources that can be connected.
An additional four digital inputs are available on S/PDIF
connectors with sample rate conversion to 48 kHz. All 12
inputs are included in the audio matrix and can be assigned
DSP functions prior to distributing signal at line level.
The DX1208 can also receive up to 6 logic inputs and
send up to 3 logic outputs, programmable via the included DX
Navigator control software. Control of the DX1208 via third
party systems (i.e., AMX and Crestron) is easily attained with
an RS-232C serial connection (DB9) on the rear panel. Two
RJ-45 connections are provided as well for linking multiple (up
to eight) DX Link enabled products together in a ring network
topology.
A remote control port (RJ-25 connector) is included on the
rear panel, facilitating the connection of two different types of
remotes (UR-1 and UR-2), all mounted on wall panels. Up to 10
remotes can be attached to the DX1208 (more when external
power is supplied), and each is individually addressable and
configurable.
The DX1208 is supplied with DX Navigator control
software that allows access to all of the system’s settings and
configurations using a personal computer (PC). The expected
range of user-adjustable processing, such as EQ filters, gates,
compressors, limiters, AGC, ducking and priority assignment,
delay, gain, and crossovers are included. The Automix feature
employs a gain sharing automixer, to keep the overall system
gain constant. In addition, up to 24 programmable presets are
available per DX1208, which can be used to store and recall
frequently used settings. The programming interface is flexible,
with connection via the USB port on the front panel, or the
Ethernet jack or DB9 connector on the rear panel.
The DX1208 is UL and CE approved. It is designed for
continuous use in professional fixed installation systems and
employs a universal power supply (100-240 VAC, 50/60 Hz).

13. RS232
18. LOGIC I/O
This is an RS-232C port on a 9-pin (DB9) connector. It
connects to a personal computer or other compatible
control system for external control of the DX1208 settings.
This may be used instead of the USB port or the Ethernet
connection for programming the DX1208.
The DX1208 provides six logic inputs and three logic
outputs on Euroblock connectors. The inputs can be used
to control a variety of DX1208 functions via external
switching, such as preset recall or channel muting. The
outputs can be used to provide logic for external indicators
and switches to indicate a range of internal settings and
conditions.
14. ANALOG OUTPUTS A-H
Eight balanced line-level outputs are provided on these
Euroblock connectors, labeled A-H.
Each logic input and output is comprised of two pins, the
active pin and ground. See “Connecting the Logic I/O”
on page 8 for suggested logic input and output wiring
examples.
15. ANALOG INPUTS 1-8
Connect eight balanced mic or line-level inputs to these
Euroblock connectors. The input gain is adjusted in the DX
Navigator software application to accommodate a mic or
line-level signal. 48V phantom power can also be applied
to a microphone input by activating it in the DX Navigator
DX1208 user-interface.
3. HARDWARE INSTALLATION
The DX1208 ships with rack ears installed, which allows
the unit to be mounted in a standard 19" rack, requiring one
rack unit (1.75"). When mounting in a rack, use plastic washers
to protect the rack ears from the mounting screws.
16. ANALOG INPUTS 5-8
These RCA connectors accept unbalanced line-level
inputs (–10 dBV) to accommodate consumer sources such
as CD or MP3 players. The left and right inputs for each
channel are summed to mono internally. It is possible to
have a signal connected to both balanced (Euroblock) and
unbalanced (RCA) connectors for inputs 5-8. The signals are
summed together in the analog domain, just prior to A/D
conversion.
Note: Since the DX1208 is convection cooled with
ventilation slots on the sides and top, please allow one rack
space above the DX1208 to allow proper ventilation.
If you do not rack mount the DX1208, you may remove the
rack ears if desired.
Connections
17. S/PDIF IN 9/10 and 11/12
Connecting Balanced Sources
These RCA connectors are used to connect S/PDIF digital
inputs to the DX1208. The sample rate is automatically
detected and converted to 48 kHz for internal processing.
Use high-quality three-conductor cable for balanced input
connections. The better the shield, the better the audio signal
is protected from induced EMI and RFI.
Note: With screw-down Euroblock connectors, it’s best
to use stranded wire that is not tinned. Solder can “flow”
under the pressure of the screw-down terminal and cause the
connection to become loose.

on port settings and control protocol for the RS-232
connection. Visit www.eaw.com for more information.
DX LINK connection
Connecting the REMOTES
An RJ-25 connector on the rear panel is used to connect
the optional remote control peripherals. You can connect
up to 10 remotes on the remote bus. More remotes can be
connected to the remote bus, provided that external power is
supplied to the additional remotes. Refer to the documentation
provided with the remote control units for more information.
There are currently two types of remote controls available
for the DX1208. Each remote has two RJ-25 connectors, one
for connecting the remote bus from the previous device and the
other for connecting to the next device. Each remote also has
an eight position DIP-switch for assigning its unique address.
DX1208 – 9
UR-1
The UR-1 has a rotary encoder and a function button to
fit a single-gang decora plate, and mounts in a single-gang
electrical box.
AC Power Considerations
The DX1208 has a built-in universal power supply and
can accept an AC voltage ranging from 100 V to 240 V. Each
DX1208 draws an average of 0.5 amps of AC line current at
120 VAC.
Warning: Always use a 3-conductor AC power cord with
a safety ground connection. Never remove the ground pin or
attempt to bypass it. This is very dangerous.
4. SOFTWARE INSTALLATION
UR-1
The encoder is used to increase or decrease the volume of
an input or output. A ring of 15 LEDs surrounding the encoder
indicates the relative audio level. The function button can be
programmed for a number of actions, such as "Mute an Input"
or "Recall a Priority." When the function is activated, the LED in
the button lights. Programming is done in the Remotes window
of DX Navigator.
UR-2
The UR-2 has four function buttons to fit a single-gang
decora plate, and mounts in a single-gang electrical box.
Each button can be programmed to perform a different action.
When a function is activated, the LED in the button lights.
Programming is done in the Remotes window of DX Navigator.
The DX Navigator software application is provided on a CDROM, which can be installed on a PC. It provides a graphical
user interface (GUI) for controlling the digital signal processing
(DSP) for multiple DX Series products, including the DX1208.
Check our website at www.eaw.com for software upgrades
as they become available.

Establishing Communication
Over USB
There are a few steps required to establish communication
between DX Navigator and the DX1208.
1. Click “Tools” in the top menu bar and select
“Communications” from the drop-down menu. The
Communications window opens.
5. Double-click the DX1208 icon in the “Found Devices” tab
to open the DX1208 interface. Click on the tabs across the
top of the DX1208 interface to open individual screens for
accessing controls and settings. The tabs include Input,
Priorities, Automix, Output, DXLink, Logic I/O, Remotes,
and Settings.
6. Refer to the Help file for detailed information about each
of the screens. To open the Help file, return to the DX
Navigator window, click “Help” in the top menu bar, and
select “DX1208 Help.”
Communicating Over Ethernet
You can connect your computer to the DX1208 directly with
an Ethernet connection, or indirectly over an Ethernet switch or
local area network (LAN).
Direct Connection
The DX1208 can be connected directly to your computer
using a crossover Cat5/Cat5e Ethernet cable.
2. Click the “COM Port” radio button and select the COM Port
that is assigned to the USB port that is connected to the
DX1208.
If you are not sure which COM Port is being used, open
the Device Manager on your computer, locate “Ports (COM
& LPT)” in the list and click the “+” sign in front of it. You
should see “EAWC DX Family USB Serial Port” followed by
a COM port number. This is the number you should select in
DX Navigator’s Communications window.
Click “OK” to close the Communications window.
3. Click “Go Online.” DX Navigator will begin to query the
DX1208 and the COMM LED on the DX1208 should light.
4. Once communication is established, the DX1208 icon
appears in the “Found Devices” tab with a green
checkmark in front of it.
When the DX1208 is connected via Ethernet, it requires
an IP address and will initiate a DHCP (Dynamic Host
Configuration Protocol) request for an IP address from a DHCP
server. Since no DHCP server exists on a direct connection, it is
necessary to assign a static IP address to the DX1208 in order
to communicate over Ethernet.
To assign a static IP address:
1. Connect your computer to the DX1208 using the USB port.
2. Open DX Navigator, click “Go Online,” and open the
“Settings” tab in the DX1208 GUI. In the IP section, select
“Static IP” and enter 169.254.xxx.xxx, where xxx can be
any number between 1 and 254. This is a private IP address
used for link-local addressing, but you can enter a privateuse IP address if you prefer. Remember the number that
you entered. You will need it again.
In the Subnet field, enter 255.255.0.0.
Note: Refer to RFC-3927 for information on link-local
addressing, and RFC-1918 for information on address
allocation for private internets.
3. Go offline and turn the DX1208 off.
Note: You must power cycle the DX1208 in order for the
Static IP address to take effect.
4. Connect the DX1208 to your computer with an Ethernet
cable and turn the DX1208 on.
5. In DX Navigator, click “Tools > Communications” in the top
menu bar.
6. Click the “Specify Target IP Addresses” radio button. Enter
the same IP address that you entered previously for the
DX1208 and click “Add” to add it to the list of IP Addresses
that DX Navigator will search for when it goes online.
14 – DX1208
7. Click “OK.” Click “Go Online” and the DX1208 icon will
appear in the “Found Devices” tab.
Indirect Connection
If you have multiple DX1208s installed in a system, you
may want to have them connected together in a LAN. This
allows you to connect your computer to the LAN and access
each DX1208 individually without having to physically change
connections.
Again, the DX1208 will send out a request for an IP
address. If there is a DHCP server on the network, it will assign
a unique IP address to each DX1208 on the network. If there
isn’t a DHCP server, then a unique static IP address will have to
be manually assigned to each DX1208 (see “To assign a static
IP address” above).
Once an IP address has been assigned to each DX1208:
1. Open DX Navigator and click “Tools > Communications” in
the top menu bar.
2. Select “Obtain IP Addresses By Broadcast” and click “OK.”
3. Click “Go Online.” DX Navigator will find all devices on
the network with an IP address and they will appear in the
“Found Devices” tab.
5. TYPICAL HOOKUP DIAGRAM
Note: The “Obtain IP Addresses By Broadcast” may not
work with Windows Vista yet. If you are running the Vista
operating system, it may be necessary to assign a static IP
address to each DX1208, even if there is a DHCP server on
the network, and select “Specify Target IP Addresses” in the
Communications window (see “To assign a static IP address”
in the previous section).
Communicating Over RS232
A rear panel RS-232C serial port is provided for additional
third party control options. Nearly every parameter that can be
controlled with DX Navigator can also be controlled using a
third party controller (i.e., AMX and Crestron models).
Port settings and control protocol will be provided in a
separate document. Visit our website for more information at
www.eaw.com.
Upgrading the Firmware
From time to time, EAW Commercial will release upgrades
for the internal operating firmware in the DX1208. This
can be downloaded from our website (www.eaw.com) to a
PC-compatible computer along with instructions on how to
upgrade the firmware.

am to 5 pm PST (Monday-Friday) to verify the problem and
obtain a Return Authorization (RA) Number. Be sure to have
the serial number of the unit when you call. You must have
a Return Authorization Number in order to obtain warranty
service at an authorized service center. You can also

3. Include a legible note stating your name, return shipping

problem, including how we can duplicate it.
4. Write the Return Authorization Number in BIG BOLD
PRINT on the top of the box.
5. Tech Support will tell you where to ship the unit when you
call for an RA Number. We suggest insurance for all forms
of cartage.

important. LOUD Technologies is not responsible for
any damage that occurs during shipping due to nonconventional packaging. Original packaging helps to
minimize the possibility of shipping damage.
