Power Conditioner
The Furman PL-Plus DMC is a rack staple that cleans up your AC power while giving you real-time voltage and current monitoring via its front panel meters. The pull-out rack lights are genuinely useful for dark stage-side setups, and the linear filtering protects sensitive audio and digital gear from power line noise. A smart first-piece-in for any IEM or playback rack build.

01 · What it does—and what that changes in your rig.
Start with the payoff, then work through how it functions, where it fits, and the details that change a real build.
Every rack gets its power from somewhere, and the PL-Plus DMC is the classic answer to making that somewhere trustworthy. It sits at the top of the rack doing three jobs: series-mode surge suppression and EMI/RFI filtering for everything downstream, a voltmeter/ammeter you can read from across the stage, and the signature Furman pull-out LED rack lights that have located a thousand loose XLRsThe standard 3-pin locking connector for mics and balanced line signals — pin 1 is the shield, pins 2 and 3 carry the balanced pair. in dark corners.
The digital meter is the part touring users actually rely on. Walking into a venue and watching the mains sag to 108V under load — or ride up hot on a generator — before your mixers and transmitters find out is exactly the kind of cheap insurance a rig needs. The current readout earns its keep at plan time too: add up your rack's draw in this app, then confirm reality against the meter at soundcheck.
Be clear about what it is not: a power conditionerFilters venue AC, clamps surges, and gives the rack one tidy inlet. Not a voltage regulator and not a battery — just cleaner power. is not a UPSUninterruptible Power Supply — a battery that rides the rig through brownouts and generator hiccups so computers never reboot mid-song. and not a voltage regulatorActively holds the output at a steady 120 V while venue power sags or spikes — a step beyond filtering, one short of a battery.. A brownout will still sag through it, and a dropoutA brief audio gap when the radio link fails — the thing diversity, distros, and coordination all exist to prevent. will still drop your digital consoles — if the rig has computers or a digital mixer that must survive a two-second generator transfer, budget a UPS below this unit and feed the critical gear from that. Conditioner for the analog and RFRadio Frequency — the wireless part of wireless. RF planning is why big rigs scan, coordinate, and combine antennas instead of hoping., UPS for the brains, is the standard stack.
