6.4 Outputs ADAT Optical
The ADI-648 provides 8 outputs in ADAT optical format. They are fully compatible to all ADAT
optical inputs. A usual TOSLINK cable is sufficient for connection.
With the Matrix Router de-activated, all MADI channels are copied to the 8-channel ADAT for-
mat in a logical order:
MADI In 1-8 9-16 17-24 25-32 33-40 41-48 49-56 57-64
ADAT Out 1 2 3 4 5 6 7 8
If a MADI signal in Double Wire format (standard frame) is present at the input, technically no
special processing is activated, because the output signals will be in Sample Split format
(S/MUX) right away.
In 96K FRAME mode, the ADI-648 automatically converts Double Speed data to Sample Split
(S/MUX). The data of one MADI channel will be processed and routed to two ADAT channels
according to the following table:

As the device internally always operates in Sample Split mode, the Matrix won't change its func-
tionality in Double Wire, Quad Wire (Sample Split = Single Speed) and 96K Frame (Double
Speed). In both cases the number of channels is reduced to 28/32 or 14/16. At the same time
the Matrix Router no longer operates in 8-channel, but in 4-channel or 2-channel blocks.
