BSS Audio BLU-50 Overview

The BSS Audio BLU-50 is a 4x4 signal processor with built-in BLU link that provides 48 channels of low-latency, fault-tolerant digital audio. The BLU-50 is configured, controlled, and monitored for HiQnet Audio Architect and is compatible with other members of the Soundweb London family.

The 48 channels of BLU link bus represents channels 1-48 of a larger 256 channel BLU link bus when integrated with other BLU link devices such as the BLU-800, BLU-320, BLU-160, BLU-120, BLU-BIB, and BLU-BOB devices. Up to 60 BLU link compatible devices can share channels on a single bus. As with other Soundweb London devices, 12 Control Inputs, 6 Logic Outputs, and an RS-232 port allow the BLU-50 to be integrated with other compatible devices.

The 1/2 rack processor offers a fixed configuration of four inputs and four outputs, configurable signal processing, logic processing, and BLU link. The device can be powered via POE or from the included 12 VDC power adapter. The analog inputs of the BLU-50 provide software configurable gain in 6 dB increments up to +48 dB per channel. Software selectable phantom power is available per channel. The front panel provides LED indicators for phantom power, signal present, and clip information.
