q OPTICAL IN, OUT connectors
Use these connectors to input or output digital signals over opti-
cal-fiber cable. You can use the OPTICAL IN to record a digital
signal of frequency 48kHz, 44.1kHz, or 32kHz. The OPTICAL
OUT connector outputs a digital signal of frequency 44.1kHz.
w DIGITAL IN, OUT connectors
Use these connectors to input or output digital signals over coax-
ial (RCA-pin) cable. The digital signal format is CD/DAT (S/P
DIF).
You can use the DIGITAL IN connector to record a digital signal
of frequency 48kHz, 44.1kHz, or 32kHz. The DIGITAL OUT
connector outputs a digital signal of frequency 44.1kHz.
e ASSIGNABLE OUT jacks (AS1 to AS6)
Additional analog output jacks. Each pair (1&2, 3&4, 5&6)
operates independently of all other outputs on the A5000/A4000.
You can use these jacks to output the sound of one or more
selected samples, or to output the signal supplied through the
front panel's analog input connectors (page 97, 128). You may
also set them so that they output the same signal as the STEREO
OUT jacks (page 125).
