BLU link In/Out
The Soundweb London Digital Audio Bus (also known as “BLU link”) is a high
bandwidth, fault-tolerant bus of 256 channels at 48kHz and 128 channels at 96kHz.
Devices are connected, using Cat 5e or Cat 6 cable, in a ring from the OUT connector of
one device to the IN connector of the adjacent device. The distance between devices in
the ring can be up to 100m on Cat 5e or Cat 6 or up to 10km on single mode fiber using
the MC-1 fiber media converter. The ring topology allows any single cable fault without
loss of channels. All devices within a given Digital Audio Bus ring must be configured for
the same sample rate. The sample rate of the BLU-BIB device is automatically configured
based on remotely configured devices within the Digital Audio Bus ring.
PLEASE NOTE: BLU-BIBs with version numbers below v1.05 are not compatible with
“pull-down” sample rates (i.e running 47.952kHz for system clock instead of 48kHz;
or running 95.904kHz for system clock instead of 96kHz). Pull-down sample rates are
occasionally required in video post-production environments in the United States. If the
design requires pull-down and you have a pre v1.05 BLU-BIB, please contact Customer
Service at [email protected] for guidance. BLU-BIBs with a sticker on the rear
panel showing V1.05 or above are compatible with pull-down rates.
