A system and method automatically providing wrap interconnections for wrap diagnostic capability of analog-digital conversion systems obviating the need for wrap cables. A connector system has a first state wherein DAC outputs are automatically internally routed to corresponding ADC inputs thereby closing a wrap loop whereupon automated DAC to ADC loop tests are performed. A second switching state is provided automatically by insertion of connector plugs into the connector system whereby the loop is broken and DAC outputs and ADC inputs are made available externally to respective output and input connectors. In one embodiment the switching system has application to an audio digitizing capture and playback adapter card. In the first state the card is automatically configured for a wrap diagnostic test. In the second state effected by insertion of plugs into the input and output jacks of the switching system, the test loop is broken and the card is automatically thereby configured for normal operation wherein analog audio source material is delivered to the ADCs through the input connector and/or output of audio data re-converted from digital to analog form is provided to the output connector from the DACs.
