The DUALZDirect provides two premium independent totally passive interfaces to connect instrument, line, or speaker level signals to a mixer or other balanced inputs through high performance audio isolation transformers. Each of the high impedance single-ended 1/4" inputs is converted by a transformer into an isolated, balanced, low impedance signal output giving the DUALZDirect a very clean and neutral sound with a variety of signal sources in a variety of applications. The DUALZDirect's audio transformers have an extremely flat and wide frequency response and can handle high signal levels.

The input ATTENUATOR switches allow for a wide range of signal levels and the input THRU jacks allows for tapping off of your signal chain. The GROUND LIFT switches let you totally isolate the input and output signal grounds, when appropriate, to separate two systems, therefore reducing hum and ground-loop noise.

The DUALZDirect includes a low pass FILTERs that cut out all very high frequency interference. These Bessel filters on the outputs are placed out of the audio range and are primarily intended to reduce radio frequency interference and reduce any digital computer noise artifacts when using the DUALZDirect as an interface between a computer-based audio workstation and your monitors.

This DI is suited to Live Sound, Permanent/Fixed Install, DJ, and virtually any PA application.
