[QUOTE="Karl Barnes, post: 60496, member: 2121"] re: X32 Discussion OK, here's an observation. I took my X32 to a band rehearsal at the weekend. The band plugged into the local PA. My desk was there for an outing just to see what could be done with it. All the guys have DI boxes, on which I duly used the XLR outputs. They used the link outs to go into submixers and then into the PA from there. Not quite the way we gig, but not far off it. Either way I take the XLR out from the DI boxes. There was no direct output from the X32 to the PA being used. I was monitoring using headphones so as not to interfere with the rehearsal. I connected up the X32 to my laptop using a CAT5 cable (didn't use USB as I will eventually use a wireless router with the system). The weird thing happened when I hooked up the USB output from the expansion card to test the 32 track recording. The moment the USB connection between the desk was made, a loud hum started up on the PA. I unplugged the USB cable and the hum stopped. I repeated plugging the cable in and the hum came back. The problem was solved by removing the mains power from the laptop which would suggest that there is a ground loop of some sort when a laptop is connecting using both the Ethernet (for XControl) and USB (for recording). This was OK for an hour until the battery ran out, which would therefore not be an ideal way to set up for a gig. I've never had this problem with this laptop (Dell Studio 17) with any system I've used before (used to have a O1v96 connected via USB and audio thru a Lexicon Alpha soundcard). OK, so a quick fix would be to use a wireless router and connect wirelessly, but why should I have to do this? If the laptop is sited next to the desk I would always prefer to use a physical connection to a wireless one. This is not a complaint, it's not going to have me sending my desk back or stop me from gigging with it, it's just an observation. I've never had this sort of function available to me before, but it would be nice to be able to use it. Any thoughts? Anyone? KB [/QUOTE]
