The amplifiers are greater than 80% efficient (compared to typical 'AB Class' amplifiers of 60%), drawing less current and, therefore, reducing unwanted heat. One of the additional benefits of the new Class D amplifiers is that smaller batteries are required for standby power. The Switch Mode Power Supply offers greater efficiency and reduces unwanted heat dissipation.
Also on display will be the touch screen and download software for the popular VIGIL BVR20 Microdrive 20-zone VA routeing matrix. The software enables engineers to re-program the BVR20 on site from their laptop computer - saving time and money. Like all Baldwin Boxall VIGIL2 products, the BVR20 Microdrive meets BS5839 Part 8 and EN60849 standards and has been successfully installed in numerous public buildings throughout the world. The BVR20 will be shown in operation with the BVR16M 16-zone voice alarm controller. In addition the well received VIGIL CommuniCare (a disabled refuge communication system) and VIGIL FireCare (a Fire Telephone system) products will be on display. Both offer the user/installer cabling reductions compared to typical star wired systems, as they are both wired as loop configurations and are fully BS5839 part 9 and EN60849 compliant.
Baldwin Boxall is sharing a ProLight & Sound stand (Stand F32, Hall 8, 31 March - 3 April 2004) with its German distributor - Laauser & Vohl.
