I bought this power conditioner w/ battery backup Here is a link to specs: http://www.apc.com/products/apcav/products/index.cfm?action=detail&base_sku=S10 My question is which slot should I plug in power for my Mac Pro (6-core)? They are all labeled for tv home theater components. Here is how manual describes outlets: -The "digital filter outlets eliminate noise interference for digital components (CD, DVD, CATV/SAT, Flat panel monitor, Hi-def tuner, etc) - The "video" filter outlets "provide filtering for video devices (TV & VCR). - The "Analog filter outlets provides filtering for analog-based equipment (Tuner/AUX and Preamp/Receiver). - The "high current filter outlets provide filtering for high -current devices (SUBwoofer and Amplifier). I'm asking on here because it was in this forum that someone said this is a good unit for battery backup (it has pure sine wave). Thanks in advance.
