The M 222 can be ordered with two different powering units. With the NT 222 DC, an AC adapter is supplied but portable operation from an external 12 Volt supply (e.g. car battery) is possible as well; the output is also switchable to line level.

The NT 222 AC has identical dimensions, but its mains transformer is internal and the output is not switchable to line level. Thanks to its universal output circuitry it can be used with any microphone input, whether phantom powered or not and whether balanced or not. When connected to 48 V phantom power (“P48 ON“), cable runs up to 200m can be used. “HARMONICS“ (see below) is adjustable in five steps.

The power supply offers a “TUBE DIRECT“ switch set ting in which there are no semiconductors in the signal path whatsoever. A “HARMONICS“ switch alters the Q-point of the tube, causing the gradual increase of harmonics to set in earlier, to emphasize the typical “tube sound.“

Powering units by ELVO exclusively for Schoeps:

NT 222 AC - for direct powering at the mains (90 - 260 VAC)

NT 222 DC - for powering by 12 V batteries or the included mains adapter
