It offers a flat frequency response from 10 Hz upwards, handles high signal levels with 1:1 unity gain, and delivers a clean, neutral sound ideal for professional audio setups needing noise-free signal paths. ## Description The ART DTI Dual Transformer and Isolater is a high quality totally passive audio interface that uses a pair of high performance transformers to totally separate input and output signal grounds, thereby isolating two systems and reducing hum and ground-loop noise. The DTI's audio transformers have an extremely flat and wide frequency response and can handle high signal levels while maintaining an isolated balanced output. This gives the DTI a very clean and neutral sound with a wide variety of signal sources. The transformers are wound for 1:1 unity gain and are designed to be used with impedances from 600 Ohms to 100k Ohms. Review: Good product - This product solved my ground hum issues. It does introduce a very slight degradation in audio quality as well as a slight loss in volume. I am very picky with my audio and have professional monitors and I can notice a slight loss of quality, but when you have ground problems.. this is the best solution I have found aside from fixing the actual wiring issues. I think that overall this is a good value product and works when you have no other choice. It will work best in applications where mastering and absolute sound quality are not needed. It works significantly better than the cheap rca ground hum eliminators Review: Great at first, but didnt last long! - Placed this eliminator unit on my receiver feed to my external amps to help eliminate the AC hum I was gitin. Unit worked great at first, but after about 4 weeks of use it start making a clippin noise when bein used and had to be unhooked to eliminate awful clippin sound, would not recommend fer longevity. ## Features - Reduces hum and ground loop noise - Flat and wide frequency response - Handles high signal levels - Maintains isolated balanced output - Clean and neutral sound ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0009GUOQA | | Best Sellers Rank | #36,389 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in Audio Transformers | | Brand | ART | | Brand Name | ART | | Customer Reviews | 3.7 out of 5 stars 287 Reviews | | Global Trade Identification Number | 00840402016380 | | Item Type Name | ART DTI Dual Transformer Isolator Hum Eliminator | | Item Weight | 0.34 Kilograms | | Manufacturer | ART | | Minimum Frequency | 10 Hz | | Model | DTI | | Mounting Type | Chassis Mount | | Part Number | DTI | | Power Source | Corded Electric | | Specification Met | CE | | UPC | 840402016380 | | Unit Count | 1.0 Count | | Warranty Description | 1 year. | ## Product Details - **Brand:** ART - **Item Weight:** 0.34 Kilograms - **Mounting Type:** Chassis Mount - **Power Source:** Corded Electric - **Specification Met:** CE ## Images ![ART DTI Dual Transformer Isolator Hum Eliminator - Image 1](https://m.media-amazon.com/images/I/61POxbb6aRL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Is it possible to use two sets of outputs - as in run the XLR outputs to the house PA and run the line outs to a keyboard amp so band can monitor?** A: Yes, the input signal, regardless of connector used, is present on all outputs. http://artproaudio.com/downloads/specsheets/ss_dti.pdf **Q: does it have a ground "lift" option, switchable?** A: No "BUT" all outputs are ground isolated from the chassis so a "lift" switch is not necessary when using this. **Q: I want to use my studio monitors with my Macbook Pro. What cable do I need to use to plug this into my laptop?** A: Hi Jason,I would use an 1/8" to XLR Male Y cable like this:http://www.amazon.com/Hosa-CYX-403M-Stereo-Breakout-Cable/dp/B000068OEP/ref=sr_1_9?m=A3QYKZ7LXW9O3&s=merchant-items&ie=UTF8&qid=1448889739&sr=1-9&keywords=hosa+1%2F8+to+xlrIf this was helpful, please consider purchasing from us. We have them both in stock and ready to ship. - Pixel Pro Audio **Q: My single coil pups are picking up interference (nearby laptop, etc) and causing my amp to hum and click; higher gain makes it worse. will this work?** A: You need a ground loop isolator. Some are as cheap as $20 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product *by G***M on January 6, 2024* This product solved my ground hum issues.

I see a LOT of people who treat this product as a solution to EVERY problem involving hum and buzz. This product is NOT a solution for every form of noise issue. If a system has an induced hum or buzz NOT related to a common ground problem between the two systems being isolated then the DTI will NOT solve that problem! You can try it at different points in the signal chain and MAY find a spot that kills your noise. However, if the buzz exists prior to the point in the signal chain where the DTI is connected it will probably not effect the noise because the problem already exists upstream in the signal chain. The same goes for a buzz or hum occurring due to an issue AFTER the point where you insert the DTI. Sometimes you must try the DTI at several points in the signal chain until you can interrupt the ground loop where the noise is generated. The DTI is not a noise cancellation system, it is a signal isolation system... a BIG difference. Also, a system adjacent to a large AC transformer field can have induced hum or buzz and an isolation transformer will not solve this. Moving the equipment out of the hum field of the AC transformer would be the only way to solve this issue. Also, an amplifier with bad filter capacitors that cause a hum in the signal can only be fixed by replacing the bad capacitors. You can also try a steep parametric filter to cut-off the frequencies involved to mask them if you cannot identify and solve the actual CAUSE of the noise. ## Frequently Bought Together - ART DTI Dual Transformer Isolator Hum Eliminator - Pyle Compact Mini Hum Eliminator Box - 2 Channel Passive Ground Loop Isolator, Noise Filter,AC Buzz Destroyer, Hum Killer w/ 1/4" TRS Phone,XLR Input/Output, Uses 1:1 Isolation Transformer --- ## 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.pl/products/3498040-art-dti-dual-transformer-isolator-hum-eliminator](https://www.desertcart.pl/products/3498040-art-dti-dual-transformer-isolator-hum-eliminator) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-24*
