BSS BLUCARD-IN I/O Card

The BSS BLUCARD-IN is a professional analog input expansion card designed for integration into Soundweb London BLU series processors. This card delivers four channels of balanced mic/line input with comprehensive software control, making it the go-to solution for live sound engineers and venue operators who need flexible multi-channel audio acquisition and routing within a networked digital audio infrastructure.

Audio Conversion & Input Architecture

The card features a 24-bit, 48kHz A/D converter with delta-sigma conversion technology, ensuring clean digital capture with input sensitivity ranging from 7–26 dBu. Each of the four channels accepts both balanced and unbalanced audio sources, with configurable phantom power available per channel for microphone operation—essential for running mics from a single expansion point without extra gear in the rack.

System Integration & Control

Installation requires two Combicon connectors for secure integration into compatible Soundweb London processors. Software-controlled analog gain adjustment in 6dB steps from 0dB to 48dB provides precise level management across all four channels during soundcheck and live performance, while a "Signal present" LED indicator offers immediate visual feedback for quick troubleshooting and channel verification.
