MOON XLR Mono Adaptor (Pair) for 330A / 860A / 870A

The MOON XLR Mono Adaptor is an XLR bridging adaptor that switches a two-channel MOON power amplifier into mono/bridged operation – for dedicated monoblocks with full power per unit. It's supplied as a pair.

What's the XLR Mono Adaptor for?

Because it lets you turn two stereo power amplifiers into two powerful monoblocks. The adaptor connects to the existing balanced XLR connections and switches the amplifier into bridged mono mode. That way, each amplifier drives a single speaker with full, undivided power – more headroom, better channel separation, more control. Because two units are bridged, the adaptor comes as a pair.

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

For owners of the MOON 330A, 860A or 870A who want to run two of these power amplifiers as monoblocks.

Straight talk: without a matching pair of power amplifiers, the adaptor makes no sense. And whether bridged operation suits your speakers should be clarified beforehand – we're happy to help.

Our verdict

The small part that turns two power amplifiers into a monoblock pair: unassuming, but effective. Whether mono operation makes sense for your system is something we'll tell you honestly at HD Zürisee in Wädenswil.

Frequently Asked Questions

What does the MOON XLR Mono Adaptor do?
It switches a two-channel MOON power amplifier into bridged mono operation. That way, each amplifier drives one speaker as a monoblock at full power. It's supplied as a pair because two power amplifiers are bridged.

Which power amplifiers does the adaptor fit?
Explicitly the MOON 330A, 860A and 870A. According to the manufacturer, it also works with most older models – if in doubt, we'll clarify that for you in advance with the distributor.

Do I need two power amplifiers?
Yes. Mono-bridge operation turns two stereo power amplifiers into two monoblocks. That's why the adaptor comes as a pair. With just one power amplifier, bridged mono mode can't be put to sensible use.

Why buy the MOON XLR Mono Adaptor from HD Zürisee?
Because bridged operation has to suit your system. We check its suitability with your speakers and power amplifiers, wire everything up cleanly, and as an authorised MOON dealer in Wädenswil we're there for warranty and service – with our own technician.
