DUALZDirect
Dual Channel Passive Direct Box
ARTcessories
The DUALZDirect provides two independent high quality totally passive interfaces that let you connect instrument, line, or speaker level signals to a
mixer or other balanced inputs through high performance audio isolation transformers. Each of the high impedance single-ended 1/4” inputs is converted
by a transformer into an isolated, balanced, low impedance signal output. The DUALZDirect's audio transformers have an extremely flat and wide
frequency response and can handle high signal levels. This gives the DUALZDirect 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 allows 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.
What further sets the DUALZDirect apart from other “DI” boxes are its extended features and versatility. We have added switchable low pass FILTERs
that cut out all very high frequency interference. These Bessel filters on the outputs are placed out of the audio range and are primarily intended to
reduce radio frequency interference before it gets into the main system. The filters are also very effective in reducing any digital computer noise artifacts
when using the DUALZDirect as an interface between a computer-based audio workstation and your monitors. The PHASE INVERT switches, while not
normally included with your "run of the mill" DI box, have been added to allow you to switch signal polarity right at the source. This feature is especially
handy when you are combining a direct tap with a microphone feed in the mix.
The compact black-anodized all aluminum case and it’s passive design allow the DUALZDirect 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
DUALZDirect the obvious choice.

INSTALLATION and OPERATION:
1) Connect your instrument, line, or speaker level signal to either of the or 1/4" TRS phone jacks. Connect one end of a phone jack INPUT 1 2
cable to the corresponding THRU 1/4' TRS phone jack and the other end to where your signal was going to, if connecting the DUALZDirect
inline in the signal path. Repeat for the other and INPUT THRU jacks if desired.
2) Connect a balanced line cable between the corresponding OUTPUT 1 2 or male XLR connector on the rear panel and the balanced inputs of
your audio gear. Repeat for the other if desired. OUTPUT
3) Set the input ATTENUATOR switches for best signal strength and clarity. Select the if desired (it won't affect normal audio FILTER
frequencies). Select the GROUND LIFT feature to lower hum and other ground loop noise, if present. The PHASE INVERT feature may be
used to correct phase error problems elsewhere in the audio system.
