XTA Audiocore DP448 Audio Management System DSP
Based on the world-renowned DP226, the XTA 4 series signal processing platforms use high-performance 24bit converters on all inputs and outputs, running at 96kHz to give a bandwidth of over 30kHz and a dynamic range in excess of 116dB. Each input channel has a 28-band graphic equalizer, in addition to 8 bands of fully parametric equalization. Each output path features up to 9 parametric sections, in addition to the crossover filters which themselves now offer slopes from 6dB/Octave up to 48dB/Octave.
Industry standard AES/EBU interfaces are built-in which allow the units to work with both digital inputs, and feed digital output streams. Sample rate converters are included on the inputs, allowing it to accept streams from 32kHz up to 192kHz (output sample rate is fixed 96kHz).The added convenience of the input routing matrix, each of the AES output streams can be any combination of inputs, allowing complete flexibility.
