BSS BLU-50 4x4 Signal Processor with BLU Link User Manual

1. Inleiding

The BSS BLU-50 is a compact, half-rack width signal processor designed for professional audio applications. It features a fixed configuration of four inputs and four outputs, along with configurable signal processing and logic processing capabilities. A key feature is its integration with BLU link, a low-latency, fault-tolerant digital audio bus. The BLU-50 can be powered via a 12VDC power supply, 12-48VDC terminal block, or Power over Ethernet Plus (PoE+), offering flexible installation options. This manual provides essential information for the proper setup, operation, and maintenance of your BLU-50 unit.

2. Opstelling

This section guides you through the initial setup of your BSS BLU-50 signal processor.

2.1 Uitpak en inspeksie

Carefully unpack the BLU-50 unit and its accessories. Inspect all components for any signs of damage that may have occurred during shipping. If any damage is found, contact your dealer immediately.

2.2 Die krag van die toestel

The BLU-50 offers multiple power options:

• 12VDC Power Supply: Use the included 12VDC power supply. Connect it to the DC input jack on the rear panel.
• 12-48VDC Terminal Block: The device can accept 12-48VDC via the terminal block connector on the rear panel. Ensure correct polarity when connecting.
• Krag oor Ethernet Plus (PoE+): Connect a Cat 5e Ethernet cable from a PoE+ enabled switch or injector to the Ethernet port. This allows the device to be powered, configured, controlled, and monitored via a single cable.

2.3 Connecting Audio Inputs and Outputs

The BLU-50 features four analog inputs and four analog outputs. These are typically connected using balanced audio cables.

• Analoog insette: Connect your audio sources to the input terminal blocks (A1-A4) on the rear panel. These inputs offer software-configurable gain in 6dB steps up to +48dB per channel and software-selectable Phantom Power per channel.
• Analoog uitsette: Connect your audio destinations to the output terminal blocks (B1-B4) on the rear panel.

2.4 Network and Control Connections

The BLU-50 integrates into a larger system via several control and network interfaces:

• Ethernet-poort: Used for PoE+ power, configuration, control, and monitoring via HiQnet Audio Architect or HiQnet London Architect software.
• BLU link: Connect compatible BLU link devices using standard Category 5e cabling to the BLU link IN and OUT ports. This creates a low-latency, fault-tolerant digital audio bus of 48 channels. Distances up to 100m are supported, and fiber media converters can extend this to over 10km.
• RS-232-poort: For integration with third-party control systems.
• Control Inputs & Logic Outputs: 12 Control Inputs and six Logic Outputs are available for integration with other compatible devices and systems.

3. Operating the BLU-50

Once the BLU-50 is physically connected, its operation is primarily managed through software.

3.1 Sagtewarekonfigurasie

The BLU-50 is configured, controlled, and monitored using either HiQnet Audio Architect or HiQnet London Architect software. These applications allow you to:

• Adjust input gain and enable/disable Phantom Power for each analog input.
• Configure signal processing blocks (e.g., EQ, dynamics, routing).
• Set up logic processing for control inputs and outputs.
• Monitor device status and audio signals.
• Integrate the BLU-50 with other Soundweb London devices on the BLU link bus.

Refer to the respective software manuals for detailed instructions on using HiQnet Audio Architect or HiQnet London Architect.

3.2 Voorpaneel-aanwysers

The front panel of the BLU-50 provides clear LED indications for various statuses, allowing for quick visual checks without a PC:

• Fantastiese krag: Indicates when phantom power is active on an input channel.
• Signal Present: Illuminates when an audio signal is detected on an input or output channel.
• Knip: Indicates that the audio signal on a channel is clipping, suggesting a need to reduce input gain.
• BLU Link Status: LEDs indicate the status of the BLU link connection.
• Power/Status: General power and operational status indicator.

4. Onderhoud

The BSS BLU-50 is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure its longevity:

• Skoonmaak: Gebruik 'n sagte, droë lap om die buitekant van die eenheid skoon te maak. Vermy die gebruik van vloeibare skoonmaakmiddels of oplosmiddels, aangesien dit die afwerking of interne komponente kan beskadig.
• Ventilasie: Ensure that the ventilation slots on the unit are not obstructed. Proper airflow is crucial to prevent overheating.
• Omgewing: Operate the BLU-50 in a stable environment, away from extreme temperatures, humidity, dust, and direct sunlight.
• Firmware -opdaterings: Periodically check the BSS website for firmware updates. Keeping the firmware current can provide performance improvements and new features.

5. Probleemoplossing

If you encounter issues with your BLU-50, consider the following basic troubleshooting steps before contacting support:

• Geen krag:
  • Verifieer dat die kragtoevoer korrek gekoppel is en funksioneer.
  • If using PoE+, ensure the Ethernet cable is properly connected to a PoE+ enabled port and the switch is providing power.
  • Check the 12-48VDC terminal block connections for correct polarity and secure wiring.
• Geen klankinvoer/-uitvoer:
  • Check all analog audio cable connections.
  • Verify input gain settings and phantom power status in the configuration software.
  • Ensure that signal routing is correctly configured within HiQnet Audio Architect/London Architect.
  • Check front panel 'Signal Present' and 'Clip' LEDs for activity.
• BLU link Issues:
  • Ensure Cat 5e cables are securely connected to BLU link IN/OUT ports.
  • Check BLU link status LEDs on the front panel.
  • Verify that all BLU link devices are powered on and configured correctly within the software.
• Software Connection Problems:
  • Ensure the Ethernet cable is connected and the network settings on your computer are correct.
  • Verify that the BLU-50 has a valid IP address and is discoverable by HiQnet software.
  • Temporarily disable any firewalls on your computer that might block communication.
