ART Pro Audio DualZDirect Dual Professional Passive Direct Box

Professional audio engineers know that signal integrity can make or break a performance, which is why the DUALZDirect stands as the ultimate solution for pristine audio isolation. This dual-channel passive DI box features high-performance audio isolation transformers that convert high-impedance single-ended 1/4" inputs into isolated, balanced, low-impedance outputs. The unit handles instrument, line, or speaker level signals with exceptional clarity, maintaining an extremely flat and wide frequency response even at high signal levels.

The DUALZDirect goes beyond standard DI functionality with comprehensive control options including input attenuator switches for various signal levels, input thru jacks for signal chain tapping, and ground lift switches to eliminate hum and ground-loop noise. Its switchable low-pass Bessel filters effectively reduce radio frequency interference and digital computer noise artifacts, making it particularly valuable when interfacing computer-based audio workstations with monitoring systems.

Additional professional features include phase invert switches for signal polarity control – essential when combining direct signals with microphone feeds. The compact black-anodised aluminium construction ensures durability across live sound, permanent installations, DJ setups, and PA applications. With its passive design requiring no power source and comprehensive feature set, the DUALZDirect provides reliable, trouble-free operation for demanding professional audio environments.
