Review: Efficace sur by-pass ampli atoll - Bonjour, J’avais un soucis lorsque je branchais un câble rca sur la sortie by-pass de mon ampli atoll in80 signature relié à un ampli home cinéma. Lorsque ma pompe à chaleur se déclenchait, des sifflements se produisaient dans les enceintes mais uniquement en by-pass. J’ai essayé plusieurs solutions, notamment des filtres de courant mais rien ne fonctionnait. J’ai acheté ce boîtier et miracle plus de sifflements. En parcourant un formum, j’ai couplé cette solution à la mise à la terre du châssis de l’amplificateur home cinéma. Et du coup je n’ai même plus de parasites également. Donc je recommande pour ceux qui auraient le même soucis. ## Features - Vergoldete - Insulated RCA jacks. - Distortion Factor: 0 - 0.01 - Input/Output impedance: 12 KOhm.Fequen Zbreich: 20 to 25,000 Hz, optimally suited for subwoofer ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B017HBBOP4 | | Additional Features | Built-In Bluetooth Receiver | | Brand | OEHLBACH | | Built-In Media | Inhalt: 1 Stück | | Color | Metallic Brown | | Compatible Devices | Personal Computer | | Connectivity Technology | Cinch | | Customer Reviews | 3.9 out of 5 stars 190 Reviews | | Cycles | AC Motor | | EU Spare Part Availability Duration | 1 Years | | Enclosure Material | Metal | | Global Trade Identification Number | 04003635090527 | | Included components | Inhalt: 1 Stück | | Item Dimensions L x W x H | 7.3L x 6.3W x 2.7H centimeters | | Item Weight | 92 Grams | | Item weight | 92 Grams | | Manufacturer | Oehlbach Kabel GmbH | | Material | Metal | | Maximum Rotational Speed | 45 RPM | | Maximum rotational speed | 45 RPM | | Mfr Part Number | 4003635090527 | | Model Name | D1C9052 | | Model Number | 9052 | | Power Source | Corded Electric | | Signal Format | Analog | | Signal-to-Noise Ratio | 70 dB | | Special features | Built-In Bluetooth Receiver | | Style Name | Modern | | Unit Count | 1 Count | ## Product Details - **Brand:** OEHLBACH - **Connectivity technology:** Cinch - **Included components:** Inhalt: 1 Stück - **Special features:** Built-In Bluetooth Receiver - **Material:** Metal ## Images ![OEHLBACH 9052 Audio Linear 8, RCASeparation Filter/Noise Suppressor/Ground Loop Isolator, Perfect for Subwoofer - Image 1](https://m.media-amazon.com/images/I/71IV5JnNbtL.jpg) ![OEHLBACH 9052 Audio Linear 8, RCASeparation Filter/Noise Suppressor/Ground Loop Isolator, Perfect for Subwoofer - Image 2](https://m.media-amazon.com/images/I/71lDQ+E9HrL.jpg) ![OEHLBACH 9052 Audio Linear 8, RCASeparation Filter/Noise Suppressor/Ground Loop Isolator, Perfect for Subwoofer - Image 3](https://m.media-amazon.com/images/I/71ikFACmJ7L.jpg) ![OEHLBACH 9052 Audio Linear 8, RCASeparation Filter/Noise Suppressor/Ground Loop Isolator, Perfect for Subwoofer - Image 4](https://m.media-amazon.com/images/I/715SRhWlxaL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ ⭐⭐⭐⭐⭐ Eliminated my RCA noise *by P***A on 13 August 2026* I bought the Oehlbach Audio Linear 8 to eliminate a annoying electrical/EMI noise from my RCA connection.
