ANALOG TO DIGITAL CONVERTERS






U2110 / U2111




MCN HOME

STEREOPHONIC PORTABLE ANALOG TO DIGITAL CONVERTER




The U2110 is a 24 bit / 96 kHz high resolution analog to digital converter.
It offers two balanced transformerless analog inputs for Left and Right channels on the rear panel, one AES/EBU digital output on the front panel.

The fully balanced design implemented in the analog front end and the converter stages provide noise and distorsion free signal processing, with no phase alteration. A specific algorithm allows 16 and 20 bit resolutions to be obtained through dithering of the 24 bit data flow, protecting the audio signal definition at low level.

A high stability internal master clock is the reference for 44.1 kHz, 48 kHz and 96 kHz sampling frequencies and 16, 20 and 24 bit quantizations.
Small sized and portable, the U2110 is an ideal companion for the  U1126 or the  U1127 preamplifier.
