ART DUALZDirect Dual Professional Passive Hum Reducing Versatile Direct Box
ART DUALZDirect - Professional Dual-Channel Passive Direct Box. 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.
