BSS Audio Debuts Its Soundweb London BLU-GPX Network-Controlled GPIO Expander

June 13, 2013

ORLANDO, Florida – HARMAN’s BSS Audio today announced the introduction of its Soundweb London BLU-GPX GPIO Expander, a versatile network-controlled GPIO (General Purpose Input/Output) component that facilitates the addition of Control Inputs, Logic Outputs and relays to systems that require extra analog control and interfacing capability. The BLU-GPX complements existing Soundweb London devices but can also be used as a standalone device, providing comprehensive logic processing, in addition to GPIO integration.

“The BSS BLU-GPX offers system designers a versatile new tool for networked audio/video integration,” said Iain Gregory, Market Manager, Installed Sound, HARMAN Signal Processing. “Whether providing additional Control Inputs for analog control of Soundweb London 100 Series systems using BLU-BIB and BLU-BOB devices for I/O expansion or facilitating sophisticated integration of disparate systems in large-scale applications, the BLU-GPX represents an affordable and straightforward solution.”


The BSS Soundweb London BLU-GPX features 36 Control Inputs (GPI), 23 Logic Outputs (GPO) and eight integrated NC/NO (Normally Closed / Normally Open) relay outputs. The BLU-GPX includes two PoE Power-over-Ethernet ports for communication and primary power, a 12VDC power connector for backup power, an RS-232 port for compatibility with serial devices and 47 Common (ground) connections. This large number of ground connections allows simplified wiring to and from external equipment.

The BLU-GPX is fully configurable using HARMAN’s HiQnet London Architect™ configuration, control and monitoring software. It features the same extensive selection of Logic Processing Objects as the other Soundweb London processors and offers the same drag-and-drop style of programming. The BLU-GPX has 48 user-configurable front-panel multicolor LEDs, enabling users to customize LED status indication for each application. In addition to LED status indication, custom text can be written to the front panel LCD by the logic system to give, for example, more detailed status information. An internal buzzer can also be sounded by the logic system to give audible indication of particular statuses.
The BSS Soundweb London BLU-GPX GPIO Expander is available now.
