The BSS Audio 1U Rack-Mount Kit allows up to two half-rack Soundweb London devices—BLU-BIB and BLU-BOB1—to be mounted on a shelf occupying a single rack space.

The 1U Rack-Mount Kit can accommodate one BLU-BIB device, one BLU-BOB1 device, two BLU-BIB devices, two BLU-BOB1 devices, or one of each device. With each device offering eight channels of analog I/O expansion, the 1U Rack-Mount Kit allows for higher I/O density (16 channels) in a single rack space.

For instances in which only one I/O expander is mounted, the included half-rack blanking plate can be used to fill the blank space in the front of the rack.
