1. Introduction Thank you for choosing the RME EXB technology. The TDIF Expansion Boards adds an 8- channel TDIF interface to all ADAT-capable RME cards. Special features include manual choice of clock reference, status LEDs and a word clock output.
Connecting a TEB to the second ADAT In of a HDSP 9652. Remove the jumper ST5, plug DIGOUT of the TEB on both right and middle pin of ST5. 6. Operation and Usage Switch on the computer and boot the OS. The green LED on the TEB is lit when the power supply is present.
7. Word Clock In the analogue domain one can connect any device to another device, a synchronization is not necessary. Digital audio is different. Correct interpretation of digital audio data is dependent upon a definite sample frequency. Signals can only be correctly processed or transferred be- tween devices if these all share the same clock.
8. Double Speed Sample rates above 48 kHz were not always taken for granted, and are still not widely used because of the CD format (44.1 kHz) dominating everything. Before 1998 there were no re- ceiver/transmitter circuits available that could receive or transmit more than 48 kHz. Therefore a work-around was used: instead of two channels, one AES line only carries one channel, of which the odd and even samples are being distributed to the former left and right channels.
