MOON XLR DC Filter (Pair)

The MOON XLR DC Filter is an inline filter for the balanced XLR connection that reduces DC voltage in the signal – designed for cases where a power amplifier shuts down due to detected DC voltage. It's supplied as a pair.

What's the XLR DC Filter for?

Because a small DC component in the signal can trigger a power amplifier's protection circuit and cause it to shut down. The XLR DC Filter is looped into the balanced connection between preamp and power amplifier and blocks that DC component – with the same function as the RCA variant, just for the XLR path. Result: the chain runs stably, without you having to give up balanced cabling.

Who is the filter for – and who isn't it for?

For anyone with balanced XLR cabling whose power amplifier shuts down due to DC detection.

Straight talk: as with the RCA variant, if your system runs stably, you don't need the filter. It solves a specific problem and isn't a general sound tweak.

Our verdict

The same specialist tool as the RCA DC Filter, just for the balanced connection: targeted against DC-related shutdown. Whether it helps in your case is something we'll tell you honestly at HD Zürisee in Wädenswil.

Frequently Asked Questions

What does the MOON XLR DC Filter do?
It reduces DC voltage in the balanced XLR connection. That helps when a power amplifier shuts down due to detected DC. The filter is looped in between preamp and power amplifier and supplied as a pair for stereo.

What's the difference to the RCA DC Filter?
The function is identical – both reduce DC in the signal path. The XLR DC Filter sits in the balanced XLR connection, the RCA DC Filter in the unbalanced RCA path. You choose the variant to match your cabling.

When do I need the filter?
Only if your power amplifier shuts down due to DC detection and you use balanced (XLR) cabling. If your system runs stably, it's not needed. If in doubt, we'll check whether it makes sense in your case.

Why buy the MOON XLR DC Filter from HD Zürisee?
Because a filter like this only helps in the right case. We clarify the cause of the shutdown, choose the matching variant, and as an authorised MOON dealer in Wädenswil we're there for warranty and service – with our own technician.
