ground loop

I helped a relative get the same setup as me with a Wiim Ultra and a Hypex power amp. The hardware is not that important here because the problem is not there. Instead ill explain the wiring setup from source to speakers. TV - HDMI ARC - Wiim Ultra - RCA - Power amp - Speaker cable - speakers...

I've got the Issue that when i try to play audio via USB I'm getting a annoying noise that i can't seem to fully fix. From what i found out could it be caused by the USBs "Framerate", which is 1kHz, but how can i stop it? The only Idea i got is getting a powered USB-Hub, but i wanted to ask if...

Hi, Are MC cartridges prone to damage in shipping such that ground loops in otherwise fine systems become common, or is it me? I recently bought my first MC cartridge, Rega Ania Pro, to replace an Exact II. I mounted the Ania Pro, changed the JC3+ back pannel setting to MC 50-500 ohms...

Hi everyone, thanks for taking the time to look this over, its really driving me crazy. The problem: I am getting a loud buzzing noise, with a noticeable 60-hertz tone in my recordings. Where I'm at: First, everything is plugged into a single surge protector (just a bog standard one...

Hi, I have a hum from my speakers (these: https://www.amazon.co.uk/gp/product/B003L92O5Q/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) which I'm pretty sure is from a ground loop. I purchased this: https://www.amazon.co.uk/dp/B08G9J74VX?psc=1&ref=ppx_yo2ov_dt_b_product_details and the hum is...

Got the Scarlett 3rd Gen and mated with JBL 104 monitors, and I'm quite pleased with it the combination. Been playing music while editing content I produce, and I noticed there's random playback glitches. Not cracks, or pops, or birdies, but glitches in playback. Sources can be mp3 or FLAC, but...

Hello, First time poster with a Pro Audio question, but first a little intro to myself. I have been a daily "lurker" at ASR for over 2 years, but this is my very first post as an official registered member. Came here originally for find a DAC recommendation and eventually bought the Topping...

I understand how ground loops can be a problem and where they come from. What I'm surprised of is in fact the opposite: why are ground loops often not a problem? The specific context I'm thinking of is a CD reader connected via RCA cables to an amplifier, while both devices are earth grounded...

My sub has 60hz hum, which seems to be caused by a ground loop (only manifests when connecting via RCA cable to the receiver). The sub is powered by a different outlet (no way to work around this), so a ground loop would make sense. There is quite a bit of discussion on the forum to avoid...

First time poster :). I ran into a ground hum problem (very loud) in the following chain: Rega P1 TT ----> Schiit Mani/iFi Zen Phono (doesn't matter which one) ----> miniDSP 2x4 HD (rca in--rca out) ---->Topping PA 5 x 2* ----> DIY LXmini speakers. (*The RCA to TRS cables for interfacing the...

Hi everybody, I need help making an XLR input on a regular single end amplifier. Since regular cable adapters wouldn't work, I decided using a transformer and already got the general purpose Lundahl 1588. I saw that they use them in some high end amplifiers. The reason I need XLR input is for...

Almost a year ago I posted this short IMD comparison of various transformers in a iso box review by @amirm, and promised that I'll try to follow up with a more detailed post. This will be it. :) A few different types of devices will be measured and compared, here's a list of units under test...

I just purchased a KRK S8.4 subwoofer to use with my existing Audioengine A5+ speakers, connected to my PC via a USB DAC. The introduction of the subwoofer is causing noise issues and I'd appreciate some help in making sense of the current situation. All of my components are connected to a...

I always wondered does ethernet cables cause ground loops? I was told all my life for the most part that ethernet cables can carry surges and ground loops but I never really encountered this. Our internet for the most part is stringed across various network switches and routers via different...

Hello, I am looking for advice on how to solve ground loop issues on my home computer setup. The main thing is that I want to be able to quickly switch between a desktop computer and a laptop for the audio source. Here is a schematic of the setup : I am considering replacing the power strip...

I'm hearing ground noise from my PC source. It's a custom tower PC, which through a Apple Type-C to 3.5 mm, connects to a Schiit Asgard 3 which powers my HE-4XX headphones. Noise is source-agnostic, connecting to mobile devices removes the noise completely. While PC headphone out, or USB ports...

Hey guys, I think I have a power issue in my cinema room. I recently hooked up a second BK XLS200 Mk2 subwoofer but I'm bumping into something I can't yet wrap my head around. I hope this is the right place to ask for advice and learn. :) Thanks in advance! The new subwoofer I added has a...

Hi all, Fresh to the forums and audio world and would like some assistance of this strange issue. I recently bought a Schiit Asgard 3 straight from the US (I'm from Australia) and are experiencing 2 strange issue. A bit of background of my usual set up: After the first couple of days of...

Hi all This is a question lifted from another thread, I would like to confirm the answer before buying anything :) Question: My motherboard has a S/PDIF header, and I am considering getting something like this to connect my PC to a DAC via toslink optical. Are there any caveats with this...
