Bosch security systems has launched the Plena-loop amplifier, which is an addition to its Plena public address and voice-alarm system range, introduced in response to the DDA. The Plena-loop also follows the launch of another product, Bosch’s Integrus infrared, wireless distribution system for hearing aid assistance.
The EVAC-compliant, Plena-loop amplifier integrates inductive-loop, hearing aid facilities, for the hard-of-hearing, into the public address and voice alarm systems. This allows hearing aid users to hear announcements within a selected area. EVAC-compliant, the system meets the requirements of the IEC 60849 standard and its national equivalents for emergency messaging.
A Plena system integrates into new or existing sound systems in public areas of up to 600 square metres in area. The loop amplifier master-slave configuration supports low spillover and quadrature audio systems for high quality audio reproduction. In addition, the loop amplifier includes features – such as automatic gain control and metal loss compensation – as standard.
