Ground-loop isolator for car audio

This four-channel RCA isolator sits between a head unit and an amplifier or equaliser to remove the humming and buzzing caused by ground-loop currents. It uses a passive, in-line design with gold-plated male and female RCA connectors on each channel.

Rated 50 W continuous and 100 W peak

The unit handles up to 50 watts of continuous signal per channel and tolerates peaks of 100 watts without distortion. Systems demanding higher sustained power will exceed its capacity and require a different solution.

Passive operation with no power draw

Because the filter is completely passive it adds no electrical load, generates no heat and runs silently. There are no active components to introduce noise or require a separate power connection.

Questions about this item

Will the AFILTER-D work with my existing car head unit that uses standard RCA outputs?

Yes, the four male RCA plugs connect to the head unit outputs and the four female RCA sockets accept the amplifier leads, so it fits a standard RCA chain without adapters.

How can I confirm the isolator is removing the ground-loop hum after installation?

Play audio with the engine running; if the alternating-current hum or buzz disappears and only the music remains, the filter is suppressing the ground-loop noise as designed.

What comes in the package and do I need any extra cables?

The box contains the passive in-line isolator with four gold-plated male and four gold-plated female RCA connectors; no additional cables are required if your head unit and amp already use RCA leads.
