## Description

Expanding on Earthquake's line of audio problem-solving products: The GLI-200 ground loop isolator. The standard A/V receiver output is 600Ω yet most ground loop isolators on the market today have 200Ω at best. When using these substandard products, your A/V receiver has to deliver 3x more current or compromise the output Level. The GLI-200 comes with an impedance of 600Ω right out of the box, matching that of the industry standard. Earthquake's GLI-200 is constructed with high-quality components and will not roll-off the low frequency response due to undersized transformers resulting in substandard performance. It was designed to reduce most of the dreaded buzz and ground loop noise while maintaining high-quality sound from your audio system. The compact and rugged construction of the GLI-200 allows for it to fit into virtually any audio system, and can be mounted to any surface with its built-in mounting bracket. This will give you a cleaner looking install and allow it to be hidden out of sight. Not all hum or buzz noise situations are the same – follow the Earthquake Sound wiring guide to achieve the best performance. When it comes to audio noise and hum issues, the GLI 200 offers great problem solving solutions to most ground loop issues facing audio professionals and installers to the everyday home and car audio enthusiast.

Review: Solved Groud Loop buzzing and hum in my Home Theater set up! - Life saver. I did a fairly expensive upgrade. Added a Panamax 5400, Parasound Halo Integrated am and a Outlaw 5000 amp. Everything plugged into the Panamax, TV, Dacs, CD Player, Blue ray player, roku, modem, router and switch. I ran my Denon amp through the Halo via Home Theater Bypass and I noticed a horribly loud buzzing sound. Also a very faint hum from all in puts in the halo. I determined my source of ground loop noise was from my router which has Ethernet running to the TV, Denon, Roku and Blue Ray player. I ran this unit between the Denon and the Halo and not only did it take away the buzz, also removed all hum from that input. I still get a very faint hum from the other inputs, so I'm going to continue to play around. But this unit, especially for the price is amazing.
Review: Do not deliver original quality of sound - It works for reducing hum and buzz sound but it change sound quality. It will cut bass and high frequency sound. Eventually it sounds like very unnatural. If you like sound quality, it will be very disappointed. Use it if you want to only reduce hum and buzz sound with giving up sound stage and density and quality.

### ⭐⭐⭐⭐⭐ Transparent performance.
*by K***I on March 24, 2021*

ISO-200: Surprisingly good sound quality when connecting my iFi Zen Phono stages balanced output to an unbalanced input on my Wyred 4 sound integrated amp. Now the Zen's capabilities show through- lightning fast dynamics with a huge sound-stage. Note: I did have to create my own male 4.4mm to female XLR adapter to connect the Zen phono to the ISO-200. You can also find a combo of adapters on Amazon if you can't make your own (4.4mm male to XLR male). GLI-200: I used this version to go inline between the front Pre Out jacks of my Surround Receiver and the Theater Bypass input of my Integrated amplifier. I was getting some grungy distortion riding on what was probably bit of ground loop hum. This isolator ELIMINATED the noise, making the front channels actually sound better. I'm usually wary of adding extra parts to a signal path- but in this case: Improvement! Very recommended, especially for the price.
