Box Contains Dynavox GLI 2.1 Stereo Line Isolator Review: Solved my ground loop hum - This won't work for everyone basically because there's as many causes of humming in the system as variables affecting the weather, but it did work for me!!! Having isolated every conceivable option, checking and swapping connections, moving equipment and wanting to take a sledgehammer to my system, I fathomed the only cause of the intolerable hum was a grounding problem on the pre out RCA of my valve pre amp (little dot mk 4). It was worse when using with my preferred power amp - the PS Audio S2000. On paper, this was an ideal sonic match of retro and modern, hybrid class a, valve and class d power output. I spend many hours reading every forum and review known to Google! I'm sure I could dismantle the little dot and work out a way to better ground the terminals inside the machine, seeing I'd have to learn electronics from YouTube, I figured buying one of these was a punt worth taking. 2 mins later, putting this inline between the preamplifier and the power amplifier and the hum is gone!! Problem solved, no soldering iron and learn on the job hifi electronics degree needed. It you have a grounding hum on a phono output, try this. At least with desertcart you've got a no quibble return and refund. I already own dynavox components, a staple switching box in my system, so knew it was a trusted quality brand. I recommend this 100% Review: It works but quality is lacking - 1) The female RCA connectors on the unit are not properly supported by the chassis. When you press in the RCA cables, the connectors push back into the box. Nothing holding them apart from the solder points. These will snap-off if cables are plugged/unplugged regularly. 2) Bass frequencies are killed. Highs are accentuated. 3) Product document in German & French only. ## Features - Metal casing - Elimination of interference signals and hum loops - Gold plated RCA connectors for lossless connection - Package Dimensions: 16.0 L x 3.6 H x 8.6 W (centimetres) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01BF8LK8G | | Best Sellers Rank | 123,296 in Electronics & Photo ( See Top 100 in Electronics & Photo ) 2,126 in RCA Cables | | Brand | Dynavox | | Cable Type | Composite | | Cable type | Composite | | Colour | Black | | Compatible Devices | Personal Computer | | Compatible Phone Models | May be compatible with smartphones, specific models not listed | | Compatible devices | Personal Computer | | Compatible phone models | May be compatible with smartphones, specific models not listed | | Connectivity Technology | Adapter | | Connector Gender | Male-to-Male | | Connector Type | Component | | Connector type | Component | | Customer Package Type | Sealed anti-static bag | | Customer Reviews | 3.6 out of 5 stars 132 Reviews | | Data Transfer Rate | 25 KHz | | Frequency | 25000 Hz | | Global Trade Identification Number | 04250019127717 | | Indoor Outdoor Usage | Outdoor | | Item Shape | Round | | Manufacturer | Dynavox | | Manufacturer Part Number | 207257 | | Model Name | 207257 | | Model Number | 207257 | | Number of Items | 5 | | Number of Pins | 2 | | Other Special Features of the Product | Tangle Free | | Outer Material | Metal | | Recommended Uses For Product | home audio systems, personal computers, vehicles | | Special feature | Tangle Free | | Specification Met | RoHS, UL | | Unit Count | 1.0 count | ## Product Details - **Brand:** Dynavox - **Cable type:** Composite - **Compatible devices:** Personal Computer - **Connector type:** Component - **Special feature:** Tangle Free ## Images ![Dynavox 207257 Black Audio Isolator, 0.5m RCA Cable, Compatible with Home Audio, PC, Vehicles - Image 1](https://m.media-amazon.com/images/I/81csNZOxKpL.jpg) ![Dynavox 207257 Black Audio Isolator, 0.5m RCA Cable, Compatible with Home Audio, PC, Vehicles - Image 2](https://m.media-amazon.com/images/I/71EJDJrChZL.jpg) ![Dynavox 207257 Black Audio Isolator, 0.5m RCA Cable, Compatible with Home Audio, PC, Vehicles - Image 3](https://m.media-amazon.com/images/I/71tOfaEo7BL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solved my ground loop hum *by O***E on 23 September 2020* This won't work for everyone basically because there's as many causes of humming in the system as variables affecting the weather, but it did work for me!!!

When you press in the RCA cables, the connectors push back into the box. Nothing holding them apart from the solder points. These will snap-off if cables are plugged/unplugged regularly. 2) Bass frequencies are killed. Highs are accentuated. 3) Product document in German & French only. ### ⭐⭐⭐⭐ A VERY WELL PRESENTED ISOLASTOR *by Z***E on 25 April 2024* This isolator works better than others that I've tried but the real solution is better shielded cables, preferably "three wire" balanced. That arrangement cancels out noise completely. ## Frequently Bought Together - DynaVox 207257 GLI 2.1 Stereo Line Isolator Black - MAILESI for iPhone Charger Fast Charging,[MFi Certified] 2Pack 20W Type C Fast Charger Block with 6FT USB C Charger Cable Compatible for iPhone 14/13/12/11 Pro Max/11/Xs Max/XR/X,iPad,AirPods Pro - Anker USB C Adapter (2 Pack),High-Speed Data Transfer, USB-C to USB 3.0 Female Adapter for MacBook Pro 2020, iPad Pro 2020, Samsung Notebook 9, Dell XPS and More Type C Devices --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/106240960-dynavox-207257-black-audio-isolator-0-5m-rca-cable-compatible](https://www.desertcart.com.ar/products/106240960-dynavox-207257-black-audio-isolator-0-5m-rca-cable-compatible) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-08-17*
