Harman BSS BLU-BOB2 8 Channel Analog 1RU Rack Mount Break-Out Box Output Expander with BLU Link

Harman BSS BLU-BOB2 8 Channel Analog 1RU Rack Mount Break-Out Box Output Expander with BLU Link



The Soundweb London BLU-BOB2 or "break-out box" offers 8 channels of analog audio output expansion via the Soundweb London high bandwidth, fault tolerant digital audio bus. This expander features a low latency, fault tolerant digital audio bus of 256 channels which uses standard Category 5e cabling giving a distance of 100m between compatible devices. The BSS Audio MC-1 fiber optic media converter can be used to increase the distance between devices to over 10km (6.2 miles) using single mode fiber. The BLU-BOB2 output channels are easily configured by six DIP switches located on the rear of the device, which select consecutive channels in groups of eight.

This simple configuration allows selection of any 8-channel range from the 256 channels available on the digital audio bus. Output channel assignments are configured by DIP switch selection only. The BLU-BOB2 is not configured by HiQnet London Architect. The 8 analog line level outputs utilize the same terminal block connectors as the other members of the Soundweb London family. Signal present and power status are clearly displayed by front panel LED indicators.

Two chassis styles are available, the first (BLU-BOB1) is a half rack width, desk or wall mounted version and the second (BLU-BOB2) is a 19" single rack space version with mounting ears for equipment racks. Front panel indication and rear panel connections are identical on both versions. The BLU-BOB2 break-out box output expanders are powered by a 12V DC adapter which is included with the devices. The BLU-BOB2 and the other members of the Soundweb London family provide the building blocks of the perfectly tailored system solution.
