The PHANTOM I Single-Channel Phantom Power Supply from ART is a single-channel phantom power supply, equipped with standard XLR connectors. It supports condenser microphones with voltage requirements from 9 to 48V. Rather than operating on batteries, it is powered via the included 18 VDC power adapter.

Within the past year I've run across a second board/snake combination that makes dynamic mics sound like junk when phantom power is enabled. It could have been a wiring problem in the boards, a wiring problem in the snakes, or even a wiring problem in the mics themselves. Rather than spend billable hours troubleshooting the problem, I made an end run around it by buying this power supply for my SM86 so the boards' phantom voltages can be left off. It makes my mic sound great even under loud vocals. Sound quality is classic pristine condenser, with that unique airy top end, and totally without spit, which tells me the power supply is doing its job. Physically, this thing seems very well built. It's a lot heavier than I expected, and the case quality is outstanding, which means it'll take a lot of road abuse. This is my fourth ART product -- the other three are a Tube MP preamp, an SLA-2 power amp that I use in one of my bass guitar rack setups, and a USB Phono Plus. All have been fantastic, well built, and 100% reliable. Nothing to dislike about this one. It just sits there on the floor and does its job so I can do mine. Highly recommended, especially if you've got better things to do than figure out why console phantom isn't working right because some board or snake or mic manufacturer didn't build his hardware to spec. 5 out of 5 stars.
