IMPORTANT SAFETY INSTRUCTION – READ FIRST
This symbol, whenever it appears,
alerts you to the presence of
uninsulated dangerous voltage
inside enclosure-voltage that may be
sufficient to constitute risk of shock.
This symbol, whenever it appears,
alerts you to important operating
and maintenance instructions in
the accompanying literature.
Please read the manual.
Read Instructions: Retain safety and operating instructions for
future reference. Heed all warnings printed here and on the
equipment. Follow the operating instructions printed in this user
guide.
Do not open: There are no user serviceable parts inside. Refer
any service work to qualified technical personnel only.
Grounding: Only connect the unit to equipment with properly
grounded mains power. Do not defeat the grounding and
polarization means of the power cord plug of the connected
equipment. Do not remove or tamper with the ground
connection on the power cord of the connected equipment.
Environment: Protect from excessive dirt, dust, heat, and
vibration when operating and storing. Avoid tobacco ash, drink
spillage and smoke, especially that associated with smoke
machines.
Handling: Protect the controls from damage during transit. Use
adequate padding if you need to ship the unit. To avoid injury to
yourself or damage to the equipment, take care when lifting,
moving or carrying the unit.
Servicing: Refer servicing to qualified technical personnel.

Installation: Install the unit in accordance with the instructions
printed in the user guide.

INTRODUCTION:
Thanks for purchasing Applied Research and
Technology’s DUALXDirect. The DUALXDirect provides
two independent high quality active interfaces that let
you connect instrument, line, or speaker level signals to
a mixer or other balanced inputs. Each of the high
impedance 1/4” and XLR inputs (provided via "combo"
jacks) are buffered and converted by very low noise
active electronics into an isolated, balanced, low
impedance signal output. The DUALXDirect has an
extremely flat and wide frequency response and can
handle high signal levels. This gives the DUALXDirect a
very clean and neutral sound with a wide variety of
signal sources and over long signal runs in high noise
environments.
The input ATTENUATOR switches allow for a wide
range of signal levels and the input THRU jacks allow
for tapping off of your signal chain. The GROUND LIFT
switches let you totally separate the input and output
signal grounds, when appropriate, to isolate two
systems, thereby reducing hum and ground-loop noise.
The DUALXDirect's active circuitry is powered by
phantom voltage from the OUTPUT connections or by
an internal 9V battery, when external power is not
available. When powered by a battery, it draws less than
7.5 mA which should provide more than 100 hours of
operation with a new battery (alkaline recommended). If
phantom power is available, then the DUALXDirect will
automatically draw its power from the external source.

The POWER ON/OFF switch lights more dimly when the
unit is running off of the battery, lights more brightly
when it is running off of phantom power, and is off when
the unit is inactive.
The compact black-anodized all aluminum case and it’s
active design allow the DUALXDirect to provide years of
trouble free service in Live Sound, Permanent/Fixed
Install, D.J., and virtually any PA application. It’s full
feature set, rugged construction, and high-end
specifications make the DUALXDirect the obvious
choice.
FEATURES:
•Fully active design
•Phantom voltage or 9V battery powered
•Converts high-impedance balanced / unbalanced
inputs into 600 Ohm balanced outputs
•Switchable input attenuation (0, -30 dB)
•Switchable ground lift
•1/4" TRS | XLR combo connector inputs
•XLR connectors for balanced outputs
•Rugged extruded aluminum case

INSTALLATION and OPERATION:
1. Connect your instrument, line, or speaker level
signal to either of the INPUT 1or 21/4" TRS phone
jacks or female XLR connectors. Connect one end of a
phone jack cable to the corresponding THRU 1/4' TRS
phone jack and the other end to where your signal was
going to, if connecting the DUALXDirect inline in the
signal path. Repeat for the other INPUT and THRU
jacks if desired.
2. Connect a balanced line cable between the
corresponding OUTPUT 1 or 2male XLR connector on
the rear panel and the balanced inputs of your audio
gear. Repeat for the other OUTPUT if desired.
3. If phantom power is not available, make sure a 9V
battery is installed and push the POWER switch in to
enable battery power. When using a battery for power,
be sure to turn the POWER switch off when not using
the unit in order to maximize battery life. If phantom
power is available, there is no need to push the POWER
switch in. Power is always applied from the OUTPUT
connectors, if present. A green LED lights if power is
coming from the OUTPUT 1 connector, a red LED lights
if power is coming from the OUTPUT 2 connector. Both
LEDs light if power is coming from both connectors.
4. Set the input ATTENUATOR switches for best
signal strength and clarity. Select the GROUND LIFT

feature to lower hum and other ground loop noise, if
present.
