Equipped w/ ¼” TRS phone and XLR inputs and outputs on 2 channels. Automatically converts unbalanced to balanced signal without any signal loss - COMPACT DESIGN: This noise filter device features a high-performance ultra-compact and portable design allowing you to easily bring it anywhere. It has high-quality components and rugged construction while maintaining the highest sonic quality - 1:1 ISOLATION TRANSFORMERS: The 1:1 isolation transformer is responsible for breaking the ground loop or the loop antenna that prevents buzz for a clear sound. Also responsible for balancing audio lines. The device accepts mono or stereo connections - WORRY-FREE SHOPPING: With the PylePro PHE400 Hum/Noise Eliminator, we are confident of the quality of our product, therefore, we offer a 30-day money-back guarantee, no questions asked ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #4,336 in Musical Instruments ( See Top 100 in Musical Instruments ) #7 in Recording Signal Direct Boxes | | Customer Reviews | 4.2 out of 5 stars 2,273 Reviews | ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/71aDg+NemwL.jpg) ## Questions & Answers **Q: I need to use this on the outputs of a mixer to powered speakers. Will this handle the line levels from the mixer? Not coming from an amplifier...** A: This is a Isolation transformer designed for this exact purpose. It will take XLR or TRS from your mixer to powered speakers without a problem. IF your speakers are quiet with no connections and hum when connected to your mixer this will help cure the issue you are having. **Q: I only have ground noise when connecting my interface to a specific amp. If I connect to powered speakers or different amps, no noise. Will this help?** A: This product doesn't work at all. I've tried it connecting in different ways and it just add more noise. Maybe it works with a simple hum from bad cables. **Q: Will this work for a blue brand microphone?** A: Unfortunately, we are not familiar with blue brand but its universal to anything with XLR or ¼ so it should not be a problem if it has those jacks. **Q: Will this eliminate 60 cycle hum on a guitar with single coil pickups in a live situation with fluorescent lighting?** A: This unit is NOT designed to kill SOURCES of 60 cycle hum. It is designed to isolated the input from the output so that signal ground loops cannot happen. These types of units can work miracles in that way. If you expects to kill hum and buzz from a single coil pickup this is not going to do that. The only way that is going to happen is to put a noise gate in the circuit (to hide the hum at low signal levels) or replace the single coil pickup with a humbucking pickup. There are no magic solutions to the problem of pick-up hum outside of playing the guitar in an electrically quiet environment without light controllers, dimmers and flourescent lighting. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It eliminated the buzzing immediately—it works perfectly! *by F***B on June 2, 2026* I bought this Pyle Compact Mini Hum Eliminator, and it has exceeded my expectations. I had an annoying hum in my audio system, and this device eliminated it almost completely from the very first use. Installation was very simple—just plug it in, and you're all set. The sound quality remains clear and clean, with no signal loss or distortion. Plus, its compact size makes it easy to fit into any audio setup. The build feels solid and sturdy. I highly recommend it. ### ⭐⭐⭐⭐⭐ It does what it says. *by B***C on May 13, 2026* It does exactly as advertised, great for eliminating excess noise from ground loops. It's a simple set up, plug and go, and it's portable enough to not take up any valuable desk space. Great value for the price. ### ⭐⭐⭐⭐⭐ Awesomesauce-- if ground loop hum is your problem *by W***R on January 24, 2017* There can be many causes of hum / noise in a piece of equipment: * Bad equipment * RFI / EMI (radio frequency or electromagnetic interference) * Bad line power * Guitar-cord related ground loop (most common in guitar / microphone / amp situations) This item works dandy if you are experiencing a ground loop problem. There is a very easy way to test for this too: if you have a guitar amplifier that has unwanted hum / noise, simply unplug the guitar cord. If you're having a cord-related ground loop problem, the hum will vanish. Plug the cord back in, hum returns. That problem is exactly what this is for. Plug you guitar or microphone cord into the "in" jack, plug another into the "out" jack and to your amplifier, and this cleans it up well. An inexpensive and efficient solution. If your noise problem is caused by one of the other factors, that's not what this is designed to fix. You may need the more expensive Hum X or similar device to handle a socket-based ground loop or noise problem, or if it's a problem with electrical noise or RMI/EMI problems, you may need a pricey power conditioner. 3-prong amplifiers: A way to test for socket-based ground loop issues is to use a prong adapter-- one of those orange or gray cheap things that converts a 3 prong plug into a 2 prong. This is for TESTING only as continued us can cause problems (there's a reason your amp has 3 prongs). Plug the amp into the adapter, plug the adapter into your electric socket, and if the hum vanishes a device like the Hum X will fix the problem. Avoid the temptation to just keep using the cheap prong adapter. It removes the grounding of the amp, and is a good way to burn out an amp or even cause a line fire. Of course if your amp only has 2 prongs in the first place, this doesn't apply at all. Bottom line: if the hum is caused by issues between the guitar and amplifier-- such is very easy to check by simply removing the guitar cord-- and this product will fix that. Note that if you have a serious issue with your guitar electronics or pickups, that may require repairing. But in my case this relatively inexpensive solution nearly zeroed my hum issues. Very pleased that it worked for me. If it doesn't work for you-- at least you'll have nice clean guitar line flow and you can look for other causes for hum. ## Frequently Bought Together - 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 - Pyle Premium Direct Injection Audio Box - 2.36" x 4.09" Passive DI Unit Hum Eliminator w/ Input Attenuator to Connect Guitar & Bass, 1/4'' Impedance Transformer Connector to Balanced & Unbalanced XLR - VANDESAIL XLR Cables, 3ft 2 Pack Microphone Cable, XLR Male to Female Balanced Microphone Cord 3 pin, 3 Foot Short mic Cord Oxygen-Free Copper (OFC) Nylon Braided --- ## 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.ie/products/8117940-compact-mini-hum-eliminator-box-2-channel-passive-ground-loop](https://www.desertcart.ie/products/8117940-compact-mini-hum-eliminator-box-2-channel-passive-ground-loop) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-06-30*
