What is B-Stock and why does it cost less?

This product listing does not indicate B-Stock status based on the product name. If this is a B-Stock unit, it would be fully functional with minor cosmetic imperfections; the audio performance and all features remain identical to new.

Will the BLU-103 work in my live-sound system or installed AV setup?

Yes. The BLU-103 is purpose-built for live-sound installations, conferencing, houses of worship, and AV integration. It provides eight analog inputs and outputs with independent AEC (echo cancellation), dual VoIP support, and GPIO-based automation for triggering and control.

How does the phantom power work, and can I use it on all inputs?

The BLU-103 provides 48V phantom power on each of its eight analog input channels independently, so you can enable it per input as needed for condenser microphones or active devices without affecting other channels.

Can I control the BLU-103 remotely or integrate it with other systems?

Yes. The unit supports RS-232, GPIO, and HiQnet connectivity for software-based configuration and control. It also provides 12 control inputs and six GPIO-compatible logic outputs for triggering and automation, with Category 5e network support up to 100 meters between devices.

Is the BLU-103 suitable for home recording or music production?

No. The BLU-103 is designed specifically for live-sound installations, conferencing, and AV integration, not for home recording or music production workflows.

BSS BLU-103 I/O Device

The BSS BLU-103 is a compact 19" single rack-space audio interface built for live sound and installed systems that need bulletproof connectivity and independent audio processing. This unit combines extensive analog I/O with dual VoIP support and software-configurable signal processing, making it equally at home in venues, houses of worship, and live installations where seamless routing, clear audio quality, and reliable system control are non-negotiable.

Connectivity & Integration

The BLU-103 provides eight independent analog input and output channels, each with configurable gain up to +48dB in 6dB steps and per-channel 48V phantom power. Two integrated VoIP (SIP v2.0 or later) lines handle simultaneous connections, while RS-232, GPIO, and HiQnet connectivity give you straightforward system control and integration via software-based configuration.

Processing & Digital Architecture

Eight independent AEC (Acoustic Echo Cancellation) algorithms process incoming audio in real time, supported by a dedicated 400 MHz signal processor and a 48-channel SWL digital audio bus. Twelve control inputs and six GPIO-compatible logic outputs provide flexible triggering and automation for live mixing workflows, while Category 5e cabling supports network distances up to 100 meters between devices—a real advantage for larger venues and installations.
