This 8-channel output board features 24-bit D/A converters producing a maximum output level of 24 dBu at a dynamic range of 131 dB(A). Exceptional balancing specifications, transformer isolation, low output impedance, and optimum dynamic range provide uncritical connectivity for power amplifiers or analogue tape machines. The extensive utilisable dynamic range provides appropriate headroom even for signals with unfavourable level settings or without dynamic limiting, always enabling optimum signal quality to be achieved, for example, in mobile use. Thanks to the circuit design and the production quality, no calibration is required; therefore, manually adjustable electronic components are not incorporated. The exceptional dynamic range of the XDA+ board is the result of a sophisticated DSP technology based on wide experience in dynamic-range enhancement for D/A converters and pioneering research on the problems of D/A conversion.
