3. Sehlahisoa Overview

3.1. Tlhaloso ea Sehlahisoa

Molumoweb London BLU-103 offers a fixed configuration of 8 analog inputs and 8 analog outputs, a Voice over IP (VoIP) interface, configurable signal processing, AEC processing, and a high bandwidth, fault tolerant digital audio bus. The VoIP port enables the BLU-103 to interface with two VoIP (SIP v2.0 or later) lines. The BLU-103 contains dedicated AEC processing for up to 8 independent AEC algorithms. The AEC algorithm can be applied to signals coming from the local analog inputs or from the digital audio bus. 8 individual AEC references (one per algorithm) allow the user to provide a solution for multiple conferencing spaces using a single device. The BLU-103 and the other members of the Soundweb London family provide the building blocks of the perfectly tailored system solution.

4.1. Rear Panel Connections Overview

The following image illustrates the rear panel of the BSS BLU-103, detailing all available connections for power, audio, and control.

Figure 1: Rear panel of the BSS BLU-103 Conferencing Processor. From left to right: AC power inlet, RS232, Ethernet, BLU Link (IN/OUT), Control Inputs/Outputs, VoIP, Analog Outputs (D, C), Analog Inputs (B, A).

4.2. Khokelo ea Matla

Connect the supplied IEC power cable to the AC inlet on the far left of the rear panel. Ensure the power source is within the 100-240V, 50/60Hz range. The unit consumes 50W. Always ensure the equipment is properly earthed.

4.3. BLU Link Connection

The BLU Link ports (IN and OUT) are used for connecting the BLU-103 to other Soundweb London devices, forming a high-bandwidth digital audio bus. Use standard CAT5e or higher Ethernet cables for these connections.

4.4. Khokahano ea Ethernet

The Ethernet port provides network connectivity for control and configuration of the BLU-103 using the Soundweb London Architect software. Connect this port to your network switch or router using a standard Ethernet cable.

4.5. RS232 Khokahano

The RS232 serial port allows for integration with third-party control systems. Refer to the Soundweb London Interface Kit documentation for detailed protocol information.

4.6. Control Inputs and Logic Outputs

The Control section features terminals for external control inputs (1-12) and logic outputs (1-6). These can be configured within the Soundweb London Architect software to interface with various external devices and triggers.

4.7. VoIP Connection

The VoIP port allows the BLU-103 to connect to two Voice over IP (SIP v2.0 or later) lines, enabling direct integration into IP-based telephony systems for conferencing.

4.8. Liphetho tsa Analog

The BLU-103 provides 8 analog outputs, labeled D (1-4) and C (1-4). These are balanced outputs, typically connected to amplifiers or other audio distribution equipment using appropriate cabling.

4.9. Lisebelisoa tsa Analog

The unit features 8 analog inputs, labeled B (1-4) and A (1-4). These inputs support 48V phantom power per channel, suitable for connecting condenser microphones. Ensure proper gain staging for optimal audio quality.

5. Litaelo tsa Ts'ebetso

The BSS BLU-103 is primarily configured and controlled using the Molumoweb London Architect software, which runs on a personal computer (Windows operating system). This software allows for:

• Designing and loading audio signal processing configurations.
• Setting up AEC algorithms for each input.
• Configuring VoIP lines and parameters.
• Monitoring system status and audio levels.
• Integrating with third-party control systems via RS232 or network commands.

Refer to the Soundweb London Architect software documentation for detailed instructions on creating and deploying configurations.
