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.
Channel Select
The BLU-BIB input channels are easily configured by six DIP switches located on the
rear of the device, which select a range of 8 consecutive channels from the Digital Audio
Bus. Input channel assignments are configured by DIP switch selection only. Do not give
more than one BLU-BIB device within the same Digital Audio Bus ring the same DIP
switch settings. Doing so will result in only one of the devices passing audio onto the
Digital Audio Bus. Each BLU-BIB should have unique DIP switch settings. The BLU-BIB
is not configured by HiQnet™ London Architect. To determine the DIP switch settings
