12VDC Power Adapter
The BLU-BOB Break-Out Box output expanders are powered by a 12V DC adapter that is
included with the device (part number: PS1225DC-S/T). Use only the adapter provided.
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.
NOTE: BLU-BOBs 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-BOB, please contact Customer
Services at bss.support@harman.com for guidance. BLU-BOBs with a sticker on the rear
panel showing V1.05 or above are compatible with pull-down rates.
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 (part number:
32-1226) as all other members of the Soundweb London family (except for BLU-100,
BLU-101, and BLU-102, which require smaller connectors).
