I got these "used" for $230 each a little over a year ago on Ebay from Unique Squared. When they arrived, they were factory sealed.
They are superb reference monitors. They are rear ported, and it is recommended that they have ample space away from a wall.
beakybirdWhen yours are on with nothing playing, is there a bit of background fuzz/static coming from your tweeters?
I've noticed it on both of mine. It's nothing overly loud, and I only notice if it's dead quiet and I'm 2 feet away or less.
I've read that it's common for powered monitors to have a bit of noise.
BigEdMustaphaI have a pair. There's some white noise if you turn the in unit amplifier up to outrageous levels. If you're getting CPU static or interference from your motherboard try a group loop isolator. If this removes some of the noise but not all of it, try getting an external sound card (a DAC). Motherboard audio is sketchy at best and downright terrible at worst when compared to professional solutions.
SleuthThey are connected to an external amp via xlr. I keep the dial at the 4db mark.
There's an ever-present white noise when they're on, and only increases if I max the amplifier volume on the back of the unit, but I can never decrease it by turning the on. The only time the white noise/static goes off is when I power the monitors off.
Just wanted to see if it's normal or a defect (I sit close so I'm apt to notice. They're usually 3 feet from my head.
BigEdMustaphai could be a ground problem. if you have devices with bad powersupplies on the same outlet it could cause these problems. also try seperating the audio cables from the power cables, the power cables can in some cases cause interference.
daan_paalvastPerhaps. I'll try a different outlet as the monitor, amp power supply, monitors and laptop power adapter are all plugged in to same outlet/power strip
daan_paalvastNope, on a completely different outlet they had the same white noise at the same level. Must be the amp in the monitor or something like that.
BigEdMustaphaYou may have some ground loop issues, you can try buying a 200W 1:1 isolation transformer to plug the monitors in order to safely float the ground. In addition, I found the speaker is prone to 2.4 GHz wireless signal, especially when the antennas are parallel to the speaker at a close distance, it meant the builtin Wi-Fi antennas on the screen of a laptop.
bieragiziHow would that apply if it's only one speaker? I have the issue in only one. They are both plugged into High End Furman Power conditioners. It's most likely the power supply from what the Yamaha Authorized Repair shop said normally happens with Yamaha HS series monitors
