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
