MOON RCA DC Filter

RCA DC Filter: What It SolvesThe RCA DC Filter is an in-line filter that reduces or eliminates DC voltage that can appear on the signal path between a source or preamp and a power amplifier, restoring more efficient and reliable use of the amplifier’s power.

MOON specifically recommends it in situations where an amplifier’s protection circuit repeatedly shuts the unit down because it is detecting DC offset coming from an upstream preamp or source component.

MOON specifically recommends it in situations where an amplifier’s protection circuit repeatedly shuts the unit down because it is detecting DC offset coming from an upstream preamp or source component.

RCA DC Filter: Installed In-LineThe filter sits directly in the signal chain between the offending source or preamp output and the power amplifier’s RCA input, requiring one extra set of interconnects to bridge the filter into the run.

Because it targets a specific fault condition rather than general sound quality, it is a targeted fix rather than an always-recommended tweak for every RCA-connected system.

RCA DC Filter: Sold in PairsThe RCA DC Filter is sold in pairs, matching the two channels of a stereo unbalanced connection between a source or preamp and an amplifier.

Both filters should be fitted together on the left and right channels rather than using a single unit on only one side of the signal path.

RCA DC Filter: A Simple, Targeted FixAt a comparatively low cost next to MOON’s electronics, the RCA DC Filter is a small, self-contained accessory rather than a full replacement interconnect or cable upgrade.

It is best fitted after confirming an amplifier’s shutdowns are specifically linked to DC detection, rather than as a routine addition to every RCA-connected MOON system.
