Audio signal transformer – easy to use with great results. The Art Dual Z Direct Dual Channel Passive DI box allows you to connect any input – line speaker instrument – and send it through an isolated balanced low impedance signal output. It has a flat and wide frequency response and can handle really high signal levels. Stuffed full of features this excellent little box allows has an input attenuator switchable low pass filters and a phase invert switch. All inside a compact and rugged box. High quality interfacing Convery inputs into 600-Ohm balanced outputs. Providing you with two independent high-quality passive interfaces. Connecting instrument line or speaker level inputs has never been easier. All you need to do is plug in your input and send out to your mixer. Simple. A great set of useful features There are loads of features that help this DI box stand out. Use the input attenuator to access a wide range of signal levels. There are ground lift switches which help reduce hums buzz and whines by interrupting the ground loops between equipment. If youre getting too much high-end interference or noise from your signal you can simply apply the low pass filter to cut out all this disruptive material. And finally the phase invert switches allow you to switch the polarity right at the source. Giving you more flexibility. Rugged build Typical of all Art products this box is tough. The compact black-anodized all aluminium case allows you to take the Dual Z box anywhere and be certain it stays safe. And with its passive design theres little to go wrong. Just plug in and get on with the show.
