The ST-MPA48 from RDL contains two identical phantom power circuits and a common power supply input. If only one mic input is to be converted for phantom operation, only one circuit needs to be used. Each circuit has a mic input and a mic output. Phantom voltage appears on each of the mic input terminals. Therefore, the ST-MPA48 can convert any existing mic input into a 48 Vdc phantom powered input. Phantom voltage is not present on the output terminals.
The power supply input terminals may be fed with any dc voltage from 10.5 volts to 26 volts.
