17.3 AUDIO CABLING
As with all professional audio applications, utmost care should be taken with audio cabling for your Falcon
50. For all balanced audio cabling, only high-quality, shielded twisted-pair audio cables should be used,
mated to high-quality XLR connectors. With proper cabling techniques, long lengths can be used, but excess
cable should be avoided.
Unbalanced audio cable techniques can also be used with the Falcon 50; however, cable lengths should be
limited to less than 15 mt, less if in a high RF environment. Only high quality shielded audio cable and
connectors should be used.
17.4 DIGITAL AUDIO INPUT
The digital input features two connectors: coaxial and optic. Only one connector may be connected at a time
to avoid malfunctions (TOSLINK optical connector should be kept covered while not used).
XLR female connector is designed for AES/EBU sources (“professional standard” interface), while TOSLINK
connector is designed to carry S/PDIF signals (“consumer standard” interface).
The digital input automatically recognizes the digital format (AES/EBU, S/PDIF, etc.), the type of connection
(optic or coaxial) and can seamlessly handle 32KHz, 44.1KHz, 48KHz and 96KHz sample rates.
Coaxial input (on XLR) is transformer balanced, and so highly immune from external disturbances and noise
(EMI).

10.2.1 Converting between AES/EBU and S/PDIF interfaces
There are a number of differences in the electrical characteristics of AES/EBU and S/PDIF interfaces
which in some cases can render them completely incompatible. Although the audio data is the same in
both AES/EBU and S/ PDIF interfaces, they are indeed different formats, at least in their subcode.
AES converted to coax is NOT S/PDIF, and S/PDIF converted to XLR balanced is NOT AES.
For proper performance, AES/EBU input (XLR connector) should therefore not be used for
connection to consumer equipment providing S/PDIF format.
