Syncing Two Units
In this application, two 8824s are slaved together for sixteen channels of 24-bit A/D conversion.
Refer to figures below and on the next page. The DIP switch settings shown are for operation in
Local mode. Refer to page 7 for a detailed discussion of the 8824’s dip switch settings. The screen
from the configuration application shows how to configure the units via computer.
There are three optional configuration differences possible. Option A syncs the two 8824s
together via the Word Clock connections. Option B uses AES/EBU pair 1-2 for the sync
connection. Option C uses the ADAT optical input for sync.
Analog input signals enter the 8824 via the eight analog inputs. After conversion to digital form,
the 8824 performs format conversion and delivers the audio to the lightpipe connector.
On the return trip, the 8824 receives digital audio from the lightpipe connector. This signal is
delivered to the AES/EBU digital outputs as well as converted to analog form and delivered to
the eight analog outputs.
