6.3 Digital audio connections per AES/EBU (optional)

The AES/EBU interface (Audio Engineering Society/European Broadcasting Union) is the most widely used
digital interface for professional audio devices. The connection is balanced, negative earth, using bipolar shielded
cable with XLR connectors. We recommend the use of a high quality low capacitance cable capable of
transmitting the wide bandwidth signal (with frequencies of over 3 MHz) error free. The AES/EBU signal can
carry, in addition to the pure audio material (up to 24-bit), various code signals using a built in emphasis,
including the sampling rate present, time code information and user-definable bits. The S/PDIF digital format
found in consumer products has similarities in its data structure to the AES/EBU format. It is in principle
possible to connect an S/PDIF device (Sony Philips Digital Interface Format) to the ULTRA-CURVE PRO
AES/EBU input, although this was not intended in the design of the two formats. The S/PDIF connector is
normally an unbalanced RCA socket, requiring the use of an adaptor. Connect the tip of the RCA socket to pin
2 of the XLR, and the RCA shield to pin 3 of the XLR. The connection between the two devices should be as
short as possible.
