1. 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 PHE400
Feature
Breaks Ground Loops Safely - Maintains Highest Sonic Quality - 60 Hz Noise Removal - Removes AC Hum Noise1/4-Inch TRS Phone & XLR Inputs/Outputs on 2-Channels - High-Performance Ultra-Compact Design - Passive Device: No Power Required
Audiophile High-Quality Components and Exceptionally Rugged Construction
Description
Almost all 60Hz AC hum is caused by ground loops that act like radio antennae (loop antenna). The Hum Eliminator completely eliminates this by breaking the ground loop, making it impossible for the signal lines to pick up the AC hum and noise in the first place. Unbalanced lines are more susceptible to picking up electrical noise and RF interference than balanced lines - the longer the unbalanced cable, the greater the chance of a problem. Using this device to connect two pieces of equipment is one of the most cost-effective ways to convert between unbalanced signals and true balanced signals. Automatically Translates Signal Voltages to Match Difference in Ground Potentials.2. Rapco Horizon ISOBLOX Transformer Isolation 1:1 BLOX Device

Description
IceCube IC-1 Balanced Line Isolator and Hum Eliminator. The Radial IceCube IC-1 is a balanced line level isolator designed to quickly eliminate hum and buzz problems in an audio system by simply inserting it into the signal path. Measuring just over 4" x 1 " (10 x 4cm), the compact design begins with two super-duty glass-filled nylon XLRs at each end with heavy duty nickel-silver contacts that will not tarnish over time. Unlike other isolators that are made of plastic, the IceCube is made from solid 16 gauge steel and finished in a tough powder coat. The steel outer shell is not only more durable, it provides excellent shielding against electromagnetic fields radiated by power cables, dimmers, motors and power supplies - delivering consistently quieter results when deployed. This is augmented with a 'set & forget' ground lift switch to eliminate hum and buzz caused by ground loops. Inside the IceCube, a proprietary Eclipse transformer isolates the input from the output and blocks stray DC currents. While small transformers rarely perform well below 100Hz, the IceCube is exceptionally linear from 20Hz to 18kHz. It is also able to withstand up to +10dB at 20Hz with less than 0.01% distortion. It is a quick and easy problem solver that will eliminate noise without limiting the bandwidth or introducing phase shift, harsh sound or unpleasant artifacts. These features combine to make the IceCube an ideal problem solver for the AV technician and audio engineer that work in the fast-paced world of live touring, AV rentals and system integration.5. Subwoofer Isolation Transformer / Ground Loop Hum Eliminator, Blue Jeans Cable brand, made in USA
Feature
Most, but not all, problems with a humming subwoofer are caused by ground loops. If your powered subwoofer hums due to a ground loop between amp and sub, this transformer will fix the problem by breaking the ground connection while allowing the signal to pass through.This transformer will NOT fix hum caused by other causes, e.g., power supply issues within the sub, ground loops between devices other than the amp and sub, induced hum from power cabling placed too close to the subwoofer cable. See troubleshooting tips, below.
Comes with instruction sheet describing causes of hum, and how to track it down and eliminate it. If this transformer doesn't fix your hum issue, this means something other than a ground loop between amp and sub is responsible for the problem -- and you're welcome to return it for a full refund.
Works with any powered subwoofer with an RCA-type (unbalanced) input; no separate power required.
Made in the USA.
Description
Blue Jeans Cable Subwoofer Isolation Transformer / Subwoofer Hum EliminatorA good subwoofer can transform the home theater experience by adding a movie-theater feel to your surround sound system. But a powered subwoofer, built to amplify low-frequency sounds and effects, is also susceptible to one of the most vexing home theater problems: hum.
Troubleshooting Subwoofer Hum:
There are a few possible causes of subwoofer hum: (1) internal noise from the power supply, (2) induced hum in the subwoofer cable, (3) hum getting into the signal path prior to the subwoofer cable, and (4) "ground loop" hum from a difference in ground potential at the source and the sub. This transformer will eliminate (4), the most common cause of subwoofer hum, but will not resolve the others.
Specific troubleshooting tips:
- Cause (1), a bad subwoofer power supply, can be checked by simply unplugging the input cable from the sub and seeing if hums with no input.
- Cause (2), induced hum in the subwoofer cable, is normally caused by the cable being too close to power cords -- check cable spacing.
- Cause (3), hum getting into the signal path prior to the sub cable, is harder to diagnose, but usually the way to proceed is to test what happens when you switch or disconnect individual sources from your amp.
If the more common ground-loop issue, (4) above, is your only problem, this transformer will resolve it. This isolation transformer is a quality, US-made audio transformer which eliminates the need for a straight-through ground/ground connection between your receiver and your powered subwoofer. With the grounds on both sides isolated from one another, ground current won't flow down the shield; the result is elimination of ground loop hum. We recommend it be used with Blue Jeans Cable LC-1 subwoofer cables, which are heavily shielded to reduce induced noise, for a truly quiet, low-noise-floor subwoofer.
