16 – Options—TDIF-1 cardTASCAM DM-24 Reference Manual 121High sampling frequency considerationsNOTEWhen cascading, all units must either be in high sam-pling frequency mode or all units must be in normalsampling frequency mode.Because of the reduced number of aux sends, the cas-cade screen changes when the high-frequency modeis selected, as shown here:TDIF-1 cardThe optional TDIF-1 card provides an additionaleight channels of I/O (four in high sampling fre-quency mode).As with the built-in TDIF-1 connectors, data can beaccepted using 16, 20 or 24 bit word lengths to matchthe connected device. The card takes its values forthese input parameters from the settings made in theMULTI I/O section of “The FORMAT screen” onpage 26.The output parameters cannot be changed (fixed at24-bit, with the emphasis status echoing that of theinput).ADAT cardThe optional ADAT card provides an addition eightchannels of digital audio I/O using a “lightpipe”TOSLINK fiber connection.Any word sync connection from an ADAT connectedvia this card must be made through the on-boardWORD SYNC connector, as the card is not fittedwith a word sync input.The clock can be set as in the same way as for thebuilt-in ADAT connection (“CLOCK settings” onpage 24).All other parameters (word length and sampling fre-quency) are determined by the ADAT device, andmay not be set on this screen.NOTEThis card cannot be used in high sampling frequencymode. A message is displayed in the appropriate part ofthe screen if the card is fitted and high sampling fre-quency mode is selected.
