Make sure all of your equipment shares a good common ground including your cable/satellite tv wiring. _________________________ Music system Model 990/7500/Magnepan 1.6 QRs/Technics SL1200 MK2/Aperion S-12 Subwoofer/OWA3/Sony NS75H DVD APC H15 Power Conditioner TV System Large Advent Loudspeakers/ Polk center/Monoprice surrounds/Panasonic Viera 42 inch/Onkyo HT-RC260/Sony BDP S590/Directv Home Theater System Onkyo PR-SC886/Outlaw 7125 Klipsch RF-82 L/R,RC-62 center, RB-35 SR/SL, BENQ HT1075, Outlaw LFM1-EX/OPPO BDP-83/Directv Harmony ONE Blue Jeans and Monoprice interconnects APC H15 Power Conditioner

I connected a power cord to each Emotiva unit and fired it up. I did not hear hum. Even more convincing - wife did not hear hum. Nothing from the amp except silence! Will hold off celebrating until a week or two pass as I know things like this can come and go. But am very pumped and enjoying the silence. Thanks to butchgo for the suggestion!

mgdurand Gunslinger Registered: 11/21/03 Posts: 147 Loc: Lafayette, LA, USA	They are definitely working. Hum gone for almost 1 week now. Am very pleased at the sounds of silence. Worth the $175.00 easily! _________________________ 75" 4K HDR Sony XBR 75X95k mini-LED TV Marantz AV7706 pre-pro OPPO UDP 203 4K Ultra HD Blu-ray Player Mirage HDT Speaker System (LCR [OM-5s for L&R and HDT-F for center], SR, SL, SBR, SBL [HDT-Rs]) Dual SVS PB12-Plus Subs Outlaw Audio Model 7900 Power Amp w/Dual Emotiva CMX-2 AudioControl BijouTM THX� Equalizer Rega RP1 Turntable Dual Panamax M5300-PM Power Conditioners Dual Monster Power HTS 2500 Power Conditioners Dual Monster Power HDP 1800 Power Conditioners Clearplay Blu-ray Player Motorola VIP1200 HD cable receiver Logitech Harmony Elite Remote

I know how annoying the humming can be after going through it with my 7500. _________________________ Epson 3500 3D projector 93" Carl's Place Flexiwhite DIY screen Outlaw 976 Pre/Pro Outlaw 7500 for LCR & L/R surrounds 1- Emotiva Mini X-A100 for rear surrounds 2- Outlaw LFM-1 EX subs Oppo BDP-105 Blu-ray/DVD/SACD player Outlaw LCR (Snell Labs) for center channel duty Tekton Enzo XL L/R 4- Emotiva ERD-1s surround speakers Monster HTS3600MKII power center
