D/A conversion enhancement

The digital signal processing chain in the C1 is completed by a proprietary signal conditioning stage which optimizes the signal for conversion by numerous R-2R converters per channel.
Because each converter has a slightly different gain and offset, an automated calibration system harmonizes their operation.
In addition, in order to address low level linearity issues inherent to R-2R converters, a unique scrambling technology is applied. By sending slightly different signals to each converter through the addition of an algorithmically generated, low-level, random high-frequency noise (which is canceled out in the analog domain), the low level linearity is significantly improved.
