5 and 15.- AES/EBU Sub-D input/output/sync connectors.
There are two DB 9 connectors, the bottom one (female) for the AES/EBU inputs, and the top
one (male) for the AES/EBU outputs. The connection for both connectors is:
Pin Number Female connector connections
1 ---------- V+ input Channel 1.
2 ---------- Input ground Channel 1.
3 ---------- V+ sync.
4 ---------- V+ input Channel 2.
5 ---------- Input ground Channel 2.
6 ---------- V- input Channel 1.
7 ---------- V- sync.
8 ---------- Sync ground.
9 ---------- V- input Channel 2.
Pin Number Male connector connections
1 ---------- V+ output Channel 1.
2 ---------- Input ground Channel 1.
3 ---------- V+ sync.
4 ---------- V+ output Channel 2.
5 ---------- Input ground Channel 2.
6 ---------- V- output Channel 1.
7 ---------- V- sync.
8 ---------- Sync ground.
9 ---------- V- output Channel 2.
Notes:
 The signals that contain both audio and sync information (Channel 1 and 2) follow the AES-3
standard. The signals that contain only sync signal follow the AES-11 standard.
 Sync input signal can be used for modifying internal AES/EBU operating frequency (48kHz is
used by default).
 Sync output will repeat the external sync input signal or will give the internal 48kHz and can be
used as sync master clock for other AES/EBU equipment.
 When both channels of the audio codec are used as independent (2 mono communications),
digital audio will be in pins labeled ‘Channel 1’ and ‘Channel 2‘.
 When both channels are used together in a 128kbps connection (mono, stereo or dual
codification), only pins labeled ‘channel 1’ are used with a mono or stereo AES/EBU signal (Pins
labeled ‘channel 2’ are not used).
 At the end of this manual, the standard AES/EBU cable pinout can be found.
6 and 7.- Analog audio output connectors 2 and 1.
May be configured as send Tx (GO), send and return Tx+Rx (GO+FB) or return Rx (F’B)
outputs. Each cable should be connected with an XLR three-contact female connector. The
connection arrangement is specified as follows (depending on whether the input from the
receiving equipment is balanced or asymmetric):
Balanced outputs:
1: Ground
2: V+ output
3: V- output
Unbalanced outputs:
1: V- output and Ground
2: V+ output
3: V- output and Ground
