DUALXDirect
Dual Channel Active Direct Box
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.

INSTALLATION and OPERATION:
1) Connect your instrument, line, or speaker level signal to either of the INPUT 1 or 2 1/4" 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 2 male 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.
