Note that the connectors all protrude through holes in the chassis. Here's an applications note I wrote on USB interfaces. The Tascam US100 is my primary sound card. I use the Numark on a second laptop for the second radio with SO2R RTTY. The Tascam is a better choice because it has good level indication on the inputs. http://k9yc.com/USB_Interfaces.pdf Nothing negative about NewEgg, but these are much better products. 73, Jim K9YC
