Audio Output Connections
Connecting the Digital Outputs
You can add digital I/O capacity to the A5000/A4000 by installing the optional I/O expansion board
(AIEB1 board). The board enables direct digital output of A5000/A4000 playback and digital through-put.
For purposes of compatibility, the AIEB1 board includes two different output types: OPTICAL OUT (opti-
cal fiber) and DIGITAL OUT (coaxial cable). Note that both of these outputs always produce identical sig-
nals.
The digital outputs function as assignable outputs. You can set them to output selected samples or pro-
grams, or you can set them to produce the same output as the STEREO OUT jacks (by setting the Stereo
Out to Assignable Out parameter to DIG&OPT (UTILITY-MASTER-Out put) : page 195).
• The OPTICAL connectors are protected by plastic covers. You must remove the cover before con-
necting the cable. Please remember to replace the cover when you disconnect the cable.
