About BSS BLU-50

Take your audio processing to the next level with the Soundweb London BLU-50 4x4 Signal Processor with BLU Link. This high-performance device offers a fixed configuration of four inputs and four outputs, along with configurable signal processing and logic processing capabilities. It boasts a high bandwidth, fault-tolerant digital audio bus, ensuring seamless and uninterrupted audio transmission.

The BLU-50 is designed with an open architecture that is fully customizable through the HiQnet London Architect. This provides a user-friendly design environment, complete with a rich palette of processing and logic objects, and a simple "drag and drop" configuration method.

This signal processor stands out with its low latency, fault-tolerant digital audio bus of 48 channels. It utilizes standard Category 5e cabling, allowing for a distance of up to 100m between compatible devices. To extend the range further, fiber media converters can be used to increase the distance to over 40km.

The BLU-50 is fully compatible with the entire Soundweb London family. Its 48 channel digital audio bus represents channels 1-48 of the larger 256 channel digital audio bus when integrated with other Soundweb London devices.

The device's analog inputs offer software-configurable gain in 6dB steps up to +48dB per channel and software-selectable Phantom Power per channel. Clear front panel LED indication provides easy access to Phantom Power, Signal Present, and Clip information per channel, without the need for a PC.

The BLU-50 also features 12 Control Inputs and 6 Logic Outputs, along with an RS-232 port for integration with GPIO compatible devices. The Soundweb London Interface Kit, which details how Soundweb London systems can be integrated with third-party control systems, is included within the installation of HiQnet London Architect.

The compact half-rack wide chassis can be rack-mounted using the BSS Audio 1U Rack-Mount Kit, or alternatively, it can be under-table mounted or wall-mounted using the included brackets. The device can be powered with the included 12VDC power supply, or it can accept 12-48VDC via a terminal block connector. Additionally, the BLU-50 can be powered with PoE+ via the Ethernet port, allowing the device to be powered, configured, controlled, and monitored using a single Cat 5e cable.

In conclusion, the Soundweb London BLU-50 4x4 Signal Processor with BLU Link and its fellow Soundweb London family members provide the essential building blocks for a perfectly tailored system solution.
