Product Details

ART Zdirect Professional Passive DI Box

The Zdirect™ is a high quality totally passive interface that lets you connect instrument, line, or speaker level signals to a mixer or other balanced input through a high-performance audio isolation transformer. The high impedance single-ended 1/4" input is converted by the transformer into an isolated balanced low impedance signal source. The Zdirect's audio transformer has an extremely flat and wide frequency response and can handle high signal levels while still maintaining an isolated balanced low impedance output. This gives the Zdirect 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 jack allows for tapping off of your signal chain. The Ground Lift switch lets 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 Zdirect apart from other "DI" boxes are its extended features and versatility. ART has added a switchable low pass filter that cuts out all very high frequency interference. This Bessel filter on the output is placed out of the audio range and is primarily intended to reduce radio frequency interference before it gets into the main system. The filter is also very effective in reducing any digital computer noise artifacts when using the Zdirect as an interface between a computer based audio workstation and your monitors. The Phase Invert switch, while not normally included with your run of the mill D.I. box, has 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 its passive design allow the Zdirect to provide years of trouble free service in Live Sound, Permanent/Fixed Install, D.J., and virtually any PA application. Its full feature set, rugged construction, and high-end specifications make the Zdirect the obvious choice.

Rated 5 out of 5 by from Great di Box for the money.As far as passive Di boxes go. This one works great. The pads and filter seem to work and they gave me a very clean mix on my backline with plenty of gain. They worked great with pods and other peddles. I would recommend them to anybody that chooses Di boxes over 57's.

ART Zdirect Professional Passive DI Box

Input Thru jack allows for tapping off of your signal chain - what does this mean?

Asked by: Randy L. Houston
Most common use for this is to use a 1/4" instrument cable in for a guitar, a second 1/4" instrument from the thru jack to a guitar amp by the guitar player. The XLR jack then goes from the direct box to the mixing board for the house sound. The input thru jack is connected in parallel with the input jack.
