This may not strictly be a question for this forum so I shall be posting it elsewhere, however I hope someone may be able to help......I have a Yamaha Dolby Digital receiver connected to five Mission speakers. I have bypassed the internal amps on the Yamaha and connected Rotel THX 200 watt power amplifiers......real cool! Everything was fine and dandy until after saving for an age I bought a Toshiba MT1 projector. When powered up the vicious hum that sounded through the speakers sent me running from the room!
Everything has been unplugged individually and it all comes back to the projector. I even ran an extension lead to a neighbours so that I could power the projector from a 'clean' power source, no dice...but big buzz and hum...I sent the Rotels back to the manufacturer for checking and all was fine. Naturally being a long time reader of this forum, when I got them back I took them to a friends and checked them again...no problem there but oh brother big noise back at home in concert with the projector.
Does anyone have any ideas that might help? Heres hoping
