BLU link In/Out
The Soundweb London Digital Audio Bus 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-BOB1 and BLU-BOB2 devices is automatically configured based on remotely
configured devices within the Digital Audio Bus ring.
Channel Select
The BLU-BOB output 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. Output channel assignments are configured by DIP switch selection only. The BLU-
BOB is not configured by HiQnet™ London Architect.
Analog Output 1-8
The 8 analog line level outputs utilize the same terminal block connectors as the other
members of the Soundweb London family.
