So any noise on the ground line is not sent to the audio input of the amplifier. **Q: Can I insert this filter between my power amp and preamp in my home audio system to fix the hum problem?** A: Your hum problem is likely between your preamp and one of its inputs. Disconnect each in turn to see which is the problem. Use this there. It breaks the earth loop. If you put it between the pre and power amp, the hum is already in the audio signal, so it would not be effective at that point. **Q: Will this eliminate the buzz between my record player and receiver?** A: You can usually eliminate hum between your record player and your phono stage input by grounding the two devices together with a dedicated wire, usually built-in to the record player, which attaches to a stud on the phono preamp or stereo. Hope this helps. **Q: Will this work for a CB radio?** A: sure, it filters out noise from the power wire ## Frequently Bought Together - BOSS Audio Systems B65N High Level to RCA Converter Noise Filter for Car Audio Systems - BOSS Audio Systems KIT2 8 Gauge Complete Car Amplifier Installation Wiring Kit with Power Cables, Ground Cables, Turn-On Wire, Speaker Wire, Terminals --- ## 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.co.th/products/273173017-boss-audio-systems-b65n-high-level-to-rca-converter-noise](https://www.desertcart.co.th/products/273173017-boss-audio-systems-b65n-high-level-to-rca-converter-noise) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-09*
