- Add Phantom Powered Mics to Standard Inputs
- Two Phantom Adapters in one Module
- Phantom Conversion with Full Frequency Response
- Fully Adjustable Phantom Voltage
- Highly-Filtered Phantom Power
The ST-MPA2 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. There is no voltage on the mic output terminals. Therefore, the ST-MPA2 can convert any existing mic input into a phantom powered input. The power supply input terminals may be fed with any dc voltage from 6 volts to 52 volts. The ST-MPA2 has an internal pass transistor-regulator filter circuit which permits this incoming voltage to be adjusted to the desired phantom voltage, up to 92% of the supply input voltage. A multi-turn trimming potentiometer is provided for you to adjust for the correct phantom voltage. A multi-turn trimming potentiometer is provided to set the correct phantom voltage. | Frequency Response: | 150 Ω in/out: 15 Hz to 50 kHz (+/- 0.25 dB)
