The 24.24M Output from Ashly is a four-output expansion module for the Protea 24.24M Matrix Processor base unit. Each card provides an additional four channels of output and brings with it dedicated DSP and digital-to-analog converters. The card is field installable and require no additional programming from the base unit. Up to five output cards can be installed for a total of twenty-four outputs. Because of the on-board DSP, the base unit's processing is not impacted by the addition of the cards.
