Digital Microphone Amplifier
Digital Microphone Amplifier
CMD 2U
– for digital inputs that implement the AES 42-2006
standard
– for use with any and all microphone capsules of the
SCHOEPS ”Colette” system
– can be used with all SCHOEPS Active Accessories
(extension tubes, cables, goosenecks and CUT filters)
– offers freedom from analog interference
– designed for highest-quality music recording, but
also ideal for ENG and conference applications
– only 100 mA current consumption (digital phantom
powering as specified by AES 42-DPP, 10 Volts)
– handles the full dynamic range from the noise floor
to the absolute SPL limit without adjustment
The digital amplifier CMD 2U seamlessly extends the
SCHOEPS ”Colette” modular microphone system. Instead
of 48-Volt phantom powering, it operates with the
standard digital phantom powering of an AES 42-type
digital input. Sonically it is fully the equal of SCHOEPS'
CMC-series analog microphones, but the internal A/D
conversion eliminates analog interference and signal
losses either in the cable or at the inputs of analog
preamps and mixers.
The CMD 2U was nominated in 2005 for the ”mipa”
(Musik messe International Press Award).
CMD 2Uxt – the 40 kHz Version
This version has frequency response to 40 kHz and
beyond, and can be used with any SCHOEPS ”Colette”
capsules that are axially addressed rather than side-
addressed.
Special marking: the letters ”xt” engraved on the
back of the connector housing.
