  1. Audio Theory, Setup, and Chat
    I just got done setting up a new computer monitor to use with my laptop via HDMI. I opened up my DAW and suddenly my guitar amp's direct output had noise on it. It seems like the 1/4" balanced TRS cable out of the amp into my audio interface input is picking up something from the monitor's HDMI...
  2. Digital Projectors - Under $3,000 USD MSRP
    I have bought this projector, and it is great, except the noise. It is supposed to be 32dB in movie mode, and 38dB in presentation mode, but the fan noise is always 38dB(A), regardless of which mode it is in. I have a calibrated measurement microphone to confirm this. Searching the internet, I...

  4. Speakers
    Hi everyone, I have problem with my almost 10 years old Logitech Z-5500 speaker system. A steady high pitch noise (around 6kHz) can be heard from the satellites, which intensity does not change when turning the volume control. Noise is heard at every setting (Analog, Optical, Coax), even when...
  5. Digital Projectors - Under $3,000 USD MSRP
    I recently bought an Epson 5650 projector and is very happy with the picture and noise when the projector is in Eco mode placed on a table. After some time I mounted my projector in the ceiling, and it seems for some reason the fan speeds up when the projector is set in "ceiling" projection...
  6. High Dynamic Range (HDR) & Wide Color Gamut (WCG)
    I purchased the movie Christine (4K) from Movies Anywhere. It propagated to Prime Video (standard UHD), VUDU (Dolby Vision), and directly in the Movies Anywhere App (HDR10). I am seeing HUGE differences between the formats. In the Movies Anywhere app on HDR10, the detail is acceptable, but there...
  7. Audio Theory, Setup, and Chat
    When I connect my receiver (rca output) to my subwoofer amp (xlr input) with an RCA -> XLR cable the speakers produce static and a tone, however there is no static or hum on the subwoofer. The tone is not exactly a hum so I don't think it's ground loop noise, but I am inexperienced and don't...
  8. Headphones
    Hi, I'm after "something" (doesn't necessarily have to be a headphone, but that seems the most obvious option) that can effectively block out noise in my environment - my home study, with two nearby construction sites seemingly in competition with one another to see who can generate the most...
  9. Digital Projectors - Under $3,000 USD MSRP
    Hello, I got my UHD550X two weeks ago. But unfortunately there was a high frequency noise coming from my projector. After searching a little bit in this forum I learned it's possible the noise is coming from color wheel. So back to my situation, I contacted Optoma and send my projector to them...
  10. CD Players & Dedicated Music Transports
    Hello, I am in possession of a 1990's Samsung Home Stereo Unit (I have included a picture as an attachment). It has treated me very well over the years. However, there seems to be an issue with the 1/4 headphone port when using modern headsets. This is what I think the problem is, the TRRS...
  11. Subwoofers, Bass, and Transducers
    Hey all, looking for a bit of advice with my JBL ES150P Subwoofer. It makes this low scratchy noise, kind of like sound effects from DOOM 2016 so my girlfriend and I like to joke that it's possessed. But at some point it becomes unfunny, as I'd like my bass back. I've eliminated all sources of...
  12. Receivers, Amps, and Processors
    Hi all, I've referred to this forum many times but never needed to post before. Looking for some help with what I should do next. Should I replace my ageing (and slightly broken) AV Receiver with a new one or attempt a repair? Background I have an Onkyo AV Receiver TX-SR308 connected to my PC...
  13. Speakers
    A couple months ago I got a set of 5.1 speakers for my computer, the Swan M60-5.1. This is supposedly a very high-end brand? When the speakers are not idling they sound pretty great, especially when all of them get in on the action for movies and games. But I've noticed from the beginning that...
  14. Digital Hi-End Projectors - $3,000+ USD MSRP
    Kraine has posted his review of the DLA-X5900 (DLA-RS440) here. Some quotes: "Lcos technology generally gives a very uniform image. The X5900 is no exception to the rule, no appearance of bright corners as it could produce in the past or hot spot." "Ultra HD support was already at a very...

  16. Headphones
    I have been arguing with some friends about the way my Urbanears Zinken could be used as a pair of microphones. After I have inserted my amplifier aux-in cable into one of the headphone holes (another input) and after I have powered the amp, I was able to hear on the speakers what I was saying...
  17. Headphones
    Hi, I am a frequent flyer, and I am interested in buying a new pair of headphones. During my flights, I have tested these two: - Bose QC35: The active noise-cancelling puts some sort of pressure on my ear drums, which makes me nauseous - I have found this to be the case with all ANC...
  18. Receivers, Amps, and Processors
    I have a Denon X4300h receiver. I need to add an external power amp to it get 11 channels of output as it only has 9 amps. Temporarily, I used an old Adcom amp that I was using elsewhere. It works fine. But I don't like it for this application because you have to push the power button to...
  19. Digital Projectors - Under $3,000 USD MSRP
    Hi everyone, I recently purchased BenQ ht2050 and its emitting this high pitch noise which is very annoying. I also bought Optoma HD161x to compare with it and compared to BenQ its very silent except the normal spinning fan noise. Both BenQ and Optoma also has normal fan noises which is a low...

    Good day all, i'm having an issue understanding a noise coming from my sub, hoping someone can explain it to me. Maybe its a common noise that suppose to be there?
