The BSS BLU103 is a fixed-configuration Soundweb London signal processor offering 8 analogue inputs, 8 analogue outputs and a Voice over IP (VoIP) interface. Its VoIP port connects to two SIP v2.0 (or later) lines, making it ideal for modern teleconferencing and unified-communications installations that need dedicated AEC and DSP in a single 1U chassis.

VoIP Interface
The VoIP port enables the BLU103 to interface with two VoIP (SIP v2.0 or later) lines, bringing IP telephony directly into a Soundweb London system for conferencing and paging. For a standard analogue POTS line instead, see the BLU-102.
Features
✓Fixed 8 analogue in / 8 analogue out configuration
✓VoIP interface for two SIP v2.0 (or later) lines
✓Dedicated AEC for up to 8 independent algorithms
✓Automatic Gain Control and Noise Cancellation per algorithm
✓Open architecture, configured in HiQnet Audio Architect
✓Software-configurable gain in 6dB steps up to +48dB per channel
✓Software-selectable phantom power per input channel
✓12 control inputs and 6 logic outputs for GPIO integration
✓Front-panel LED indication of phantom power, signal and clip
✓Compatible with the entire Soundweb London family
Note
This is the VoIP variant. For a standard analogue telephone (POTS) line interface instead of SIP, choose the BLU-102.
