In Reply To: Giving up on MOTU

There are two (at least) issues that 828 users need to consider. The first is the Firewire chipset that your computer uses. IEEE1394 is a rather loose standard, and some chipsets simply won't work with the 828. I believe that the approved chipsets are listed on the MOTU website. If your's isn't compatible, you will get pops, clicks, timing errors and other disgusting things. Very frustrating. I would recommend connecting the 828 to your computer and simply trying to play back some wave files through it. You can always add a PC card with a compatible chipset if necessary. The other "issue" is the grounding scheme. The 828 uses the internal signal ground on all I/O connectors. This creates terrible noise problems when cables of any significant length are used. I "fixed" mine by building a "breakout" panel with XLR jacks and grounding pin 1 straight to the rack panel, which is then grounded to the 828 chassis. It is now very quiet. Hope that helps... Pat
