Overview

The Nady SMPS-2X is a dedicated 2-channel phantom power supply built to solve a common studio and live-sound problem: providing clean 48V DC power to condenser microphones when your mixer, preamp, or audio interface lacks built-in phantom power. It connects inline between your microphones and your mixing console using standard balanced XLR connectors — female XLR inputs accept your mic cables, and male XLR outputs pass the audio signal onward to your mixer or interface with phantom power applied.

Housed in a compact all-metal chassis, the SMPS-2X is built to withstand the demands of regular use. Its low-noise circuitry maintains a noise floor below 85 microvolts with a frequency response spanning 10Hz to 30kHz, ensuring your condenser microphones receive stable power without introducing unwanted artifacts into the audio path. The included 18V AC adapter powers the unit, and a front-panel LED confirms when phantom power is active. For anyone running condenser microphones into gear that does not supply phantom power, the SMPS-2X provides a simple and reliable inline solution.

Frequently Asked Questions

Can I power two condenser microphones at the same time with the SMPS-2X?

Yes, the SMPS-2X has two independent channels, each providing 48V phantom power, so you can run two condenser mics simultaneously.

Will the SMPS-2X add noise to my audio signal?

The unit is designed for low-noise operation with a noise floor below 85 microvolts and full-frequency response from 10Hz to 30kHz, so it should not introduce audible noise.

Does the SMPS-2X come with a power adapter?

Yes, an 18V AC 300mA power adapter is included in the box.

Can I use this with dynamic or ribbon microphones?

Dynamic microphones will not be harmed by phantom power but do not need it. However, most ribbon microphones should not receive phantom power as it can damage them — do not connect ribbon mics through this unit while it is powered on.
