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.
A stylish and very compact durable aluminum chassis
Input Attenuator switches for a wide range of signal levels
Phase Invert switch on the box for quick phase corrections
An "input thru" jack that allows for tapping off of the signal chain
A ground lift switch which lets you totally separate the input and output signal grounds, to reduce hum and ground-loop noise
