The DUALZDirect is a professional, two-channel, passive direct box that converts instrument, line, and speaker-level sources, via transformer, into signals compatible with balanced, low-impedance devices such as mixers and audio interfaces.

Both channels are totally independent and have identical features. These include attenuator switches that pad the inputs by -20 or -40 dB, and ground-lift switches that fully isolate each input from the chassis and the output to help eliminate hum and ground-loop noise.

You also get phase invert switches, 1/4" pass-through jacks, and switchable low-pass filters. The latter attenuate -3 dB at 30 kHz, and are designed to reduce radio-frequency interference (RFI) and digital computer noise.

Combine all that functionality with a solid, black-anodized aluminum case, and you've got a handy and road-worthy direct box.
