The inputs are on 1/4"/XLR combo jacks, and the outputs on balanced XLR connectors. Each channel has a ground lift switch for reducing hum and ground-loop noise, and an input attenuator switch that pads the signal coming in by 30 dB. A pair of 1/4" Thru jacks let you simultaneously pass your source signal through to an amp or other device.

The DUALXDirect runs on the phantom power of the device connected to its output. If those aren't available, a 9V battery (included) supplies the juice.
