MeanGene Desperado Registered: 06/10/02 Posts: 524 Loc: Simi Valley, CA, USA	I am having an issue with my new 990. Each time I switch inputs or mute I get a thud through the system sounding similar to a tap on a microphone. Any ideas on how to trouble shoot this? I am using a 990 to an ATI 3005 using the balanced inputs. I also have bass management going from the 990 to the SMS-1 to the Sampson using balanced inputs. _________________________ MeanGene\'s Home MeanGene\'s DVD\'s

Unfortunately, there is nothing you can do about it at home - see a technician or contact Outlaw.

I went back to the un-balanced connections and the thumb or tick went away. _________________________ Outlaw Audio Model 990 Outlaw Audio Model 7500 Polk Audio RTi150, CSi40, FX500i, PSW650 Sony KDS-55A2000 Onkyo DX-C390 Toshiba HD-A2 DirecTV HR20-700 Philips Pronto TS-1000 Pics of My System

MeanGene Desperado Registered: 06/10/02 Posts: 524 Loc: Simi Valley, CA, USA	It came with 3.07 and I upgraded to 3.11. Like the new features but still have the thumping. After reading about a few users who switched back to unbalanced connections which solved the problem I am concerned that this is not a configuration problem, but one that is inherent with the 990 when using balanced connections. _________________________ MeanGene\'s Home MeanGene\'s DVD\'s

jpk Deputy Gunslinger Registered: 01/30/07 Posts: 1	Have you resolved the problem yet? I had the same problem of thumping when muting or switching inputs when I upgraded to some modified Hafler amps. The problem was also there with a 2ch preamp. It turns out the the amps needed a capacitor input, shorting (muting) the dc input caused the problem. I'm using unbalanced RCA's. _________________________ jpk

butchgo Desperado Registered: 06/22/07 Posts: 369 Loc: Southern Oregon coast	MeanGene, I am running my 990 with balanced connections to my 2200's and 7500 and I do not experience any thumping at all. I can change inputs and mute and it is deaqd quiet. I get the inital small click or pop when everything is first turned on but that's it. _________________________ 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 Lore monitors L/R 4- Emotiva ERD-1s surround speakers Monster HTS3600MKII power center
