Inspired by an article in the December 1989 issue of Electronic Musician (by
Craig Anderton), we decided to emulate their MIDI phantom power model for RFX
equipment. MIDI receivers supply 12 VDC on pins 1 and 3, and transmitters
receive power on those same pins. Many MIDI devices can be modified to supply
power down the cable, but of course RFX makes no warranty to anyone as to the
applicability of this modification or any damage that might be done as a result
thereof. We supply this note for those adventurous people who may want to give
it a try.
