Linking multiple BlackBox Recorders together

It is possible to link multiple BlackBox MADI Recorders together to make
recordings with more than 64 channels or to make redundant copies by
duplicating the signal path completely. Each BlackBox Recorder will still
require its own USB2 disk drive as only 64 channels of data will be recorded
to each drive. This will also provide benefits in post production as many
popular DAWs will only play back a limited number of tracks from each
external drive.
As stated earlier in this manual, ensuring that the units are synchronised
with both the clocking and starting sample of each recording being locked
together is vital for being able to replay the material later in a DAW
environment. However, in a BBR64MADI system it is vital that the MADI data
is properly recovered from the MADI data stream. You will therefore want to
use either Wordclock or MADI as your reference clock.
The BBR will then use the S/PDIF link (labelled "Ext Clk" on the RCA sockets
on the rear panel) to pass control data and timecode information between
the master unit and the slave(s). The Master unit embeds this control data
and timecode into the sub-code of the SPDIF data stream. In this mode the
digital audio clock signal between units is ignored. The Slave units can either
be daisy chained together from the Master unit or preferably be fed their
clocking and control signals from a distribution amplifier. You will need short
RCA (phono) jumper cables to connect each subsequent unit.
