• BLU-BoB2

Overview:

The BSS BLU-BOB (Break-Out Box) is an output expander designed for use within Soundweb London systems. It provides a convenient way to increase the number of analog outputs available in your system by converting BLU link audio channels to balanced analog line-level signals.

The BLU-BOB integrates seamlessly with other BSS BLU-series processors such as the BLU-100, BLU-806, BLU-800, BLU-160, and others that utilize BLU link for audio distribution.

Features: 

• 8 balanced analog outputs on Phoenix/Euroblock connectors
• BLU link input and output ports for daisy-chain or loop-through connection
• Selectable channel banks for assigning any set of 8 channels from the 256-channel BLU link bus
• LED indicators for Power & Signal Presence.
• Compact, rack-mountable (1U half-rack width) form factor
• No configuration software required — channel selection via rear-panel DIP switches
• Compatible with all BSS Soundweb London devices using BLU link

How It Works:

The BLU-BOB acts as a D/A (digital-to-analog) converter within the BLU link network.

Each device on the BLU link bus can transmit or receive up to 256 channels of digital audio at 48 kHz.

By selecting a specific channel bank (1–32) using the DIP switches, the BLU-BOB extracts 8 consecutive channels from the BLU link stream and outputs them as balanced analog audio.

For example:
 

Bank 1 = Channels 1–8

Bank 2 = Channels 9–16

Bank 3 = Channels 17–24

…and so on, up to Bank 32 = Channels 249–256.

Multiple BLU-BOBs can be connected in parallel, each assigned to different channel banks to expand the total analog output count of your system.

Typical Applications: 

The BLU-BOB is commonly used to:

• Expand the analog outputs of a DSP like the BLU-100 or BLU-806DA
• Feed multiple amplifiers, zone outputs, or recording devices
• Provide analog outputs for systems primarily using digital transport (BLU link)
• Create distributed audio systems across venues, conference centers, or houses of worship

Example Scenario: A BLU-100 provides 12 inputs, processing and 8 analog outputs.

Adding one BLU-BOB increases this to 16 analog outputs, all synchronized through BLU link.

Front and Rear Panel Overview:
 

Front Panel:

• Power and Signal LEDs

Rear Panel:

• 2 x RJ-45 (BLU link IN/OUT) ports
• 8 x 3-pin Euroblock connectors for analog outputs
• 5 DIP switches for channel bank selection
• 12vDC power input

Important Notes:

The BLU-BOB is not detected in Audio Architect — it operates as a passive BLU link device.

The maximum BLU link​ cable length is 100 meters per segment (Cat5e or better).

The BLU-BOB2 version offers identical functionality but is a full rack width.
