You Won't Pay a Lot for This Passive DI!
The ART Zdirect Professional Passive Direct Box is a high-quality totally passive interface that lets you connect instrument, line, or speaker level signals to a mixer or other balanced input thru a high performance audio isolation transformer. Its high impedance single-ended 1/4" input is converted by the transformer into an isolated balanced low impedance signal source. The Zdirect 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.

Unlike traditional direct boxes, the Zdirect features a switchable lowpass filter that cuts out all very high frequency interference. This Bessel filter on the output is placed out of the audio range and is reduces 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 DAW and monitors.
The Zdirect's 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. Another non-traditional feature is a Phase Inversion switch that allows you to switch signal polarity right at the source. This 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 flexible power design allow the Zdirect to provide years of trouble free service in live sound, permanent installations, DJ booths, and virtually any PA application. The full feature set, rugged construction, and high-end specifications make the Zdirect the obvious choice whenever you have to interface high impedance sources with a low noise balanced system.
