Ground Loop Isolator for Car and Home Audio

The Bolton Technical 2 in 1 accessory includes a WisWinDa Pro AV2M-RCA noise isolator designed to reduce hum and buzzing from vehicle and home audio electrical systems. It targets ground loop interference between the audio source and the receiver to deliver HiFi quality sound output. The device works with amplifiers, speakers, or mixers for stable performance.

Aluminium Shell Construction for Sustained Use

The isolator features a high-quality aluminium shell built for sturdiness and long-term durability under continuous operation. It maintains stable performance, high precision, and good reliability during extended listening sessions in car or home stereo setups. The passive design requires no external power to suppress noise over sustained periods.

Plug-and-Play RCA Installation with Short Cables

Installation is straightforward with a plug-and-play design that needs no complicated tools; simply connect the white and red RCA cables correctly. The package includes one pair of quality RCA cords measuring .65 ft, which limits placement flexibility between components. Buyers who need longer cable runs or different connector types should verify suitability before purchasing.

Questions about this item

Does the Bolton Technical 2 in 1 accessory introduce any audible hiss or extra heat when left in the signal chain all day?

The passive aluminium-cased isolator adds no active circuitry, so it generates no hiss and no measurable heat during continuous use.

Which RCA-equipped source and amplifier must I already own for the .65 ft cords and isolator to function?

You need a device with stereo RCA outputs such as a phone adapter, media player or mixer, plus an amplifier or powered speakers with RCA inputs.

Will the ground-loop isolator work transparently with a vintage receiver that has only high-level speaker terminals?

No — the unit requires line-level RCA connections on both sides, so a receiver lacking RCA inputs cannot be used directly.
