Hi guys, i recently got myself a very strong poweramp called `E-Systemspro -Power 3000 that runs @ 3000watts bridged into 4ohm load. Its used for big gigs hince the big power of 3000watts & weights 30kg. The amp has 2 daul variable speed fans but when i switch it on only 1 comes on & the other fan doesnt come on at all.The thing is i havent yet pushed the amp hard & maybe the other fan will cut in after it gets really hot. Does anybody know if this is supposed to happen ? Is there amps that have 2 fans but 1 fan runs always & the other only comes on when the amps being pushed ?? I just got it, ive never owed a poweramp so i dont know if it should do this, why is only 1 fan running when theres 2 ? Heres a link to the owners manual but it only says the fan speed is varied automatically to maintain the proper internal operating temp ??? http://www.lightsounds.com.au/content/manuals/power3000_m.pdf Please help me im lost here!! Growly.
