The ART Xdirect is a single channel active DI box, that can be powered by the included battery or phantom power. Key features include ground lift, phase invert, fixed filter cut, and attenuation switch settings up to -20dB.
The Xdirect is a high quality interface that lets you connect instrument, line, or speaker level signals to a mixer or other balanced input. The high impedance single-ended 1/4" and XLR inputs are buffered and converted, by very low noise active electronics, into an isolated balanced low impedance signal source. The Xdirect 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 Xdirect 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 Link 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 Xdirect apart from other "Active DI" boxes are its extended features and versatility. We have added a switchable low pass Filter that cuts out all very high frequency interference. This Bessel filter on the input 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 Xdirect as an interface between a computer based audio workstation and your monitors.
