Table 3-3
Maximum cable length as a function of the cable gauge and the number of
DS50s supplied through the cable.
3.2 Audio Connections
The XLR connectors (analog audio, AES/EBU in and link) of the DS50 are wired as follows:
Pin 1 = shield
Pin 2 = normal phase ( or
“hot”)
Pin 3 = inverted phase (signal- or
“cold”)
Always use high quality XLR connectors and shielded signal cables. Using the signal link
connectors, up to 30 DS50s can be linked without a problem. If more than 30 DS50s need to
be interconnected, a separate signal driver should be used.
The input stages are electronically balanced. To make optimum use of the balanced input stages
even in unbalanced situations, use balanced signal cables and connect pin 3 to pin 1 at the
output of the preceding equipment. If this is not possible, connect pin 3 to pin 1 at the input of
the DS50.
The digital input of the DS50 offers two input channels on one electronically balanced XLR-
connector and will accept AES/EBU and S/PDIF input signals of 16 to 24 bit 44.1, 48, 88.2 or
96kHz.
