The Two M 222's Power Supplies NT 222 AC & NT 222 DC

The M 222 is available in two versions, using the identical microphone itself but two different powering units:
The M 222 with Powering Unit NT 222 AC (ordering information 'M 222 AC') for versatile use with professional equipment and mains connection 90 ... 240 V AC and the M 222 with Powering Unit NT 222 DC (ordering information 'M 222 DC') for portable use with 12V DC or mains and preamplification up to line level for DAT or HD recordings.

The Technical Data Of The M 222
With Its Power Supply NT 222 AC


• Tube Microphone Amplifier with Power Supply / Filter / Attenuator / Line Driver
• Fits for any SCHOEPS Colette Series capsule and all the Active Accessories such as CUT1, KC, RC, GVC, BLM03C
• Same dimensions as SCHOEPS CMC microphone amplifier
