In addition to eliminating common hum issues, it is equally crucial that your amplifier receives the required signal voltage to maximize available performance. If your powered equipment is not receiving the required signal voltage, then it is impossible to perform at the level that the manufacturer intended. That is why the engineers at Earthquake Sound decided to integrate a pre-amplifier into the Hum Kleaner’s noise suppression circuitry.

A ground loop occurs when your audio components are connected to different power outlets or strips, which may have minute differences in ground potentials. This difference creates a path for electrical current to flow through the shielding of your audio cables, inducing a 50Hz or 60Hz hum that corresponds to the frequency of the AC power.

Its core function involves using transformers to isolate the audio signal, passing it magnetically while physically breaking the electrical ground connection to eliminate ground loop hum without degrading audio quality.

It excels at converting unbalanced signals, such as those from RCA cables, into balanced signals like XLR or TRS, which use three wires—a pair of signal wires with one inverted and a ground—allowing the receiver to reject noise through a process called “Common Mode Rejection,’ making audio more resilient to interference especially over long cable runs. Additionally, it functions as a line driver or preamplifier, boosting low-voltage signals that can degrade over distances of 15-20 feet. The adjustable gain knob can increase output to 9V for RCA and 18V for XLR\/TRS, ensuring a strong, clean signal before long cable transmissions. Placing the Hum Kleaner near the source component, such as a mixer or AV receiver, helps maintain high-frequency detail and dynamic range by providing a high-voltage, noise-resistant signal to your amplifier or powered speaker\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Earthquake Sound","offers":[{"title":"Default Title","offer_id":42484887289922,"sku":"Hum Kleaner","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/7586\/5922\/files\/hum-kleaner-01_jpg.webp?v=1760389823"},{"product_id":"loc300r-line-out-converter-1","title":"LOC300R Line Out Converter","description":"\u003ch4 class=\"uk-h3\"\u003eFeatures\u003c\/h4\u003e\n\u003cdiv class=\"uk-margin element element-textarea\"\u003e\n\u003cul\u003e\n\u003cli\u003eHi\/Low Level Converter\u003c\/li\u003e\n\u003cli\u003eSignal Noise Eliminator\u003c\/li\u003e\n\u003cli\u003e2-Channel Signal Outputs\u003c\/li\u003e\n\u003cli\u003eAdjustable Output Level\u003c\/li\u003e\n\u003cli\u003eAuto Remote Amplifier Turn-on\u003c\/li\u003e\n\u003cli\u003eInput Audio Optimizing Circuitry\u003c\/li\u003e\n\u003cli\u003eOutput Audio Optimizing Circuitry\u003c\/li\u003e\n\u003cli\u003eIndependent Level Controls\u003c\/li\u003e\n\u003cli\u003eIntegrated Wire Strain Relief\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eDimensions\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eH x W x D: 3.93ʺ (100mm) x 2.20ʺ (56mm) x 1.18ʺ (30mm) \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Earthquake Sound","offers":[{"title":"Default Title","offer_id":42484888797250,"sku":"LOC300R","price":16.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/7586\/5922\/files\/loc-300r_01_jpg.webp?v=1759347887"},{"product_id":"hllc-200-high-low-level-converter","title":"HLLC-200 High\/Low Level Converter","description":"\u003cdiv class=\"uk-margin element element-textarea\"\u003e\n\u003cp\u003eThe HLLC-200 is a high-power differential high low adapter with several beneficial uses.
