2. INTRODUCTION
KEY FEATURES
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
rangeofuser-adjustableprocessing,suchasEQlters,gates,
compressors,limiters,AGC,duckingandpriorityassignment,
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
employsauniversalpowersupply(100-240VAC,50/60Hz).

REAR PANEL FEATURES
The front panel consists mostly of indicators showing the
status of the DX1208, with the exception of the USB connector
for easy programming access with a PC.
1. INPUT LEVEL INDICATORS
Each input channel has a pair of level indicators. The green
LED indicates the presence of a signal above –40 dBFS.
The red LED indicates when the signal is above –2 dBFS
and is close to clipping.
2. OUTPUT LEVEL INDICATORS
Each output channel has a pair of level indicators. The green
LED indicates the presence of a signal above –40 dBFS.
The red LED indicates when the signal is above –2 dBFS
and is close to clipping.
3. USB CONNECTOR
Use this standard USB connector to connect the DX1208 to
a PC with DX Navigator installed.
4. DX LINK ACTIVE
This red LED lights continuously to indicate when a DX Link
enabled device is connected to the DX LINK RX connector
on the rear panel and is communicating correctly.
7. IEC AC SOCKET
The DX1208 has a universal power supply, allowing it to
operatefromanyACmainssupplyfrom100to240VAC,
50-60 Hz. The DX1208 comes with two IEC power cables,
onefor120Voperationandonefor220Voperation.Select
the power cable appropriate for your local AC power and
connect it to the IEC AC socket.
8. ON SWITCH
Use the ON switch to turn the DX1208 on and off.
9. REMOTES
This RJ-25 connector is used to connect to one or more
optional remote controls. Up to 10 UR-family remotes may
be connected in a daisy-chain to this remote control port
(more when external power is supplied). See “Connecting
the REMOTES” on page 9 for more information on using the
remote controls.
10.
ADDRESS
Currently disabled, this multi-position rotary switch will be
implemented in future software updates.
11.
ETHERNET
5. COMM
This green LED lights to indicate communication activity
via the USB, RS-232, Ethernet, Remotes, or Logic Input
connections.
6. ON
This green LED lights when the power switch is turned
on and the DX1208 is connected to an AC mains with
sufficient voltage for operation.
This RJ-45 connector allows the DX1208 to be controlled
and programmed by a PC with a 10/100 Base-T Ethernet
connection.
12.
DX LINK RX/TX
These RJ-45 connectors are used to connect multiple DX
Link enabled devices together. The DX LINK RX connector
receives audio from devices that are located upstream in
the audio path, and the DX LINK TX connector transmits
audio to devices that are located downstream in the audio
path. See “Connecting the DX LINK RX/TX” on page 9 for
more information on using the DX Link connections.

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.
14.
ANALOG OUTPUTS A-H
Eight balanced line-level outputs are provided on these
Euroblock connectors, labeled A-H.
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-levelsignal.48Vphantompowercanalsobeapplied
to a microphone input by activating it in the DX Navigator
DX1208 user-interface.
16.
ANALOG INPUTS 5-8
These RCA connectors accept unbalanced line-level
inputs(–10dBV)toaccommodateconsumersourcessuch
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.
17.
S/PDIF IN 9/10 and 11/12
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.
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.
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.
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.
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
Connecting Balanced Sources
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.
