It breaks the ground loop safely making it impossible for the signal lines to pick up the AC noise in the first place - PASSIVE DEVICE: The noise isolator is a passive device that does not require power to operate. 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 ## Why choose this product **Pristine Audio Through Isolation** — Ground loops are a common source of frustrating AC hum in audio systems, acting like unintended radio antennae. The Pyle Hum Eliminator Box tackles this directly. Its passive design and 1:1 isolation transformer safely break these loops without affecting your audio signal's integrity. This means cleaner recordings, clearer live sound, and a more professional listening experience. Unlike active solutions that might introduce their own noise, this unit focuses purely on eliminating unwanted buzz, ensuring your music or sound is heard exactly as intended, free from distracting interference. **Ideal for Musicians & Podcasters** — This hum eliminator is perfect for guitarists, bassists, keyboardists, and podcasters who connect their instruments or microphones to mixers or audio interfaces. If you experience a persistent 60Hz buzz, especially when running long cable lengths or using multiple pieces of equipment, this device is for you. It's particularly useful for live sound engineers managing multiple channels and seeking to minimize noise floor. Those with active instruments or mixers that supply phantom power will find its passive nature a simple, effective solution. If you're experiencing hum from your amplifier or audio interface, this box can resolve it. ## How to use 1. Plug your unbalanced audio source, such as a guitar, keyboard, or microphone, into the 1/4" TRS phone or XLR input on one channel of the Pyle Hum Eliminator Box. — Connect Instrument Output 2. From the corresponding 1/4" TRS phone or XLR output on the same channel of the eliminator, connect a cable to the balanced input of your mixer, audio interface, or amplifier. — Connect to Mixer/Interface Input 3. Turn on your audio system and check the sound. The hum eliminator should have automatically converted the signal and removed the 60Hz AC ground loop noise without affecting audio quality. — Verify Signal and Noise ## Product details | Field | Value | |---|---| | Transformer Type | 1:1 Isolation Transformer | | Input Connectors | 1/4" TRS Phone, XLR | | Output Connectors | 1/4" TRS Phone, XLR | | Channels | 2 | | Power Requirement | Passive (No external power needed) | | Signal Conversion | Unbalanced to Balanced | | Frequency Response | 60Hz - 20kHz (typical for audio signal pass-through) | | Noise Reduction | Eliminates 60Hz AC Hum & Ground Loop Noise | | Cost per use | 1 unit at ₹4,326 — ₹4,326 per unit | | Shelf life after opening | N/A (Durable electronic component) | | Contraindications | Not suitable for eliminating non-ground-loop related noise or digital interference. | | Allergens / common irritants | N/A | | Brand | Pyle | | Model Name | Compact Mini Hum Eliminator Box | | Part Number | PHE400 | | Color | Charcoal | | Material | Steel | | Dimensions (L x W x H) | 6.2" x 2.5" x 7.2" (15.7 cm x 6.3 cm x 18.3 cm) | | Weight | 0.9 lbs (0.41 kg) | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Frequently asked questions ### What is the difference between an active and a passive direct box? A passive direct box uses a transformer and needs no power, working well with high-output or active-electronics instruments. An active direct box contains a powered preamp (via phantom power or battery) and is well suited to low-output passive pickups such as many electric guitars and basses. Choose based on your instrument's output level and whether power is available. This Pyle unit is passive. ### Do I need a direct box if my mixer already has instrument inputs? A direct box converts a high-impedance unbalanced instrument signal into a balanced low-impedance signal, letting you run long cable lengths to a mixer or recording interface without noise or signal loss. It also often includes a ground lift switch to remove hum. If your setup involves long cable runs or hum issues, a DI box improves signal integrity, even with mixers that have instrument inputs. ### How do I connect the Pyle Hum Eliminator Box? Connect your instrument or audio source's unbalanced output (e.g., guitar, keyboard) to the 1/4" TRS phone or XLR input on one channel of the Pyle Hum Eliminator. Then, connect the corresponding output from the eliminator to your mixer, audio interface, or amplifier's balanced input. The device automatically handles the signal conversion. ### Will this Pyle Hum Eliminator remove all types of audio noise? This Pyle Hum Eliminator is specifically designed to remove 60Hz AC hum caused by ground loops. It is highly effective for this common issue. However, it may not eliminate other types of audio noise such as digital interference, static, or microphone hiss, which can have different sources. ### Can I use this hum eliminator for stereo signals? Yes, the Pyle Hum Eliminator Box is a 2-channel device and can accept mono or stereo connections. You can use one channel for a mono source or connect stereo signals by using both channels independently for left and right audio paths. ### How to buy an original Pyle Hum Eliminator Box in India?
