Bosch Security Systems has recently extended its Plena Easy Line range with three mixer amplifiers. Available in 60 watt, 120 Watt and 240 Watt versions, the new Plena Economy units feature five inputs, including four mic/line inputs and one background music input, to provide a variety of easy solutions for broadcasting announcements and music.

The units are designed for straight-out-of-the-box use and feature a highly user-friendly user interface, preferred-setting indicator pins and standard labels for the inputs. Moreover, a variety of back panel connection points allow for true application flexibility.

The mixer section has integrated equalizers for regulating the treble and bass inputs that are easily adjusted with a simple turn of a dial. In addition, a built-in limiter prevents overload of the amplifier output signal.

The system can automatically take priority over other calls and music during announcements. It also features a 100 Volt call-only output which can be used as an additional third output for e.g. volume override or as an extra zone for announcements only.

The new Plena Economy mixer amplifiers can be added with Plena Solutions equipment (message manager, a DVD/CD-player and tuner, a timer unit, a feedback suppressor).

These new extensions to the Plena Easy Line range mean that Bosch is able to offer high quality and easy-to-use public address solutions for applications such as retail shops, restaurants, small businesses, offices and schools. Although aimed at these cost-sensitive markets, the Plena Economy is nevertheless a professional system meeting the same high quality standards as Bosch's other public address and background music systems and comes with a three year Bosch warranty.
