The original Soundweb 9010 Programmable Controller set new standards in control interfacing to DSP systems, and has yet to be bettered as a simple yet powerful interface. The Soundweb London equivalent, the BLU-10, builds on that power and reputation by adding touch-screen control to make a more attractive and potentially cost-saving control solution. It is possible that a BLU-10 could replace a more expensive proprietary touch screen solution where simpler control interfacing is required. As with the Soundweb 9010, up to 100 control 'pages' of virtually any Soundweb London DSP parameter can be constructed, with the ability to create 'folders' for nested pages. Access to specific pages or folders can be restricted with the used of password protection, so that only engineers or key employees can adjust critical system parameters. Each page can hold up to eight different functions and with navigation being carried out entirely by a page list, all of these functions can be assigned to real parameters rather than functioning as page transitions. Soundweb users will be familiar with the simple drag-and-drop programming interface, and the BLU-10 interface is very similar. Once the menu pages have been created, operation of the pages can be tested using the special simulation mode, which emulates how the controller will work when in use. This allows menu structures to be checked before the system goes live. The BLU-10 connects into a Soundweb London network via its Ethernet port, either directly into the rear of a rackmount device such as the BLU-16 with a Cat 5 crossover cable or with a standard Cat 5 cable into an Ethernet switch. The unit is powered either using the terminals on the rear, accepting a range of 12V - 48V DC or with IEEE802.3af Power Over Ethernet (POE).
