PLENA Matrix Commercial Audio System

The PLENA matrix system brings the benefits of the latest DSP technology to the fore. All DSP features of the PLENA matrix system can be accessed easily through a user-friendly Windows graphic user interface that searches the network automatically so there is no need to remember IP addresses. The Windows GUI is designed to give installers maximum control over the setup, while the iPad and iPhone GUI is designed for simplicity and ease of use for the end user. Both give end users the ability to select their own background music source and mix any microphone/line input without affecting other zones in the system.

Bosch’s dedication to excellence and focus on quality is evident throughout the PLENA matrix system, ranging from intuitive configuration interfaces, streamlined installation, simplicity of cabling, to power-packed acoustic capabilities.

The advanced features of the PLENA matrix digital sound system enable users to achieve superb audio performance with wireless control across up to eight output zones. With audio quality tailored for a wide range of applications — including live music, business music, high-demand speech environments and zone announcement — the PLENA matrix system delivers full featured digital audio control, with maximum flexibility and reliability.

Specially designed for versatility and ease of use, the PLENA matrix system enables users to control the audio settings and adjust volume levels wireless via iOS operated mobile devices such as iPhones or iPads.

The PLM-8M8 PLENA matrix eight-channel DSP matrix processor, the heart of the PLENA matrix system, provides complete control over the audio configuration and signal processing. Users can simply walk into a particular zone and match the audio quality to specific requirements — from live and background music to crystal-clear announcements.

Innovative design and economical advantages go hand in hand in the PLENA matrix system. The PLENA matrix Class-D power amplifiers feature an auto standby mode that — when activated by Bosch motion sensors in output zones that are unoccupied — helps to generate significant cost savings as compared to standard amplifiers. And by reducing overall power consumption, the environmental impact is significantly reduced.

With its single-cable approach, PLENA matrix enables efficient and quick system setup. The ‘Amp link’ feature and daisy chaining of call stations and wall panels dramatically reduces installation costs.

Intelligent and environmentally friendly, Bosch motion detectors enhance amplifiers with a smart “Auto-Standby” mode when zones are inactive. This reduces both power consumption and operating cost while increasing amplifier life.

The PC software provides a graphic user interface that is designed around the needs of the installer and end-user. Although straightforward and easy to understand, the amplifier and processor DSP feature set is more powerful than competing alternative solutions. The software allows for the easy upload of pre-stored scene settings and can also be password-protected.

Maximum audio control ensures premium sound. Input controls include multi-band equalizing, gain control, and dynamic range compression on each input. Output control includes multi-band equalizing, filtering, dynamic range compression, delay, and limiting, plus the ability to mix several inputs for up to eight outputs in real time.

There is a lot going on in your average gym these days. A yoga class in one studio, a squash game in another, a Zumba class upstairs and people hanging out in the restaurant and café. The PLENA matrix can handle it all with superbly tailored voice announcements and professional-level audio sound per zone.

With its stylish design and convenient iPad control, the PLENA matrix is all about the user experience: control a source selection from your iPad during the yoga class; page some extra help for the front desk or tap the wall station to start up the pre-game soundtrack. And the best part? Thanks to its prime energy-saving features, it pays for itself in the long run.

Small hotels must provide the same service level as larger chains – just on a different scale. In this case, the highly flexible PLENA matrix is an ideal option for audio control. With sound, live speech, voice announcements and mixing in up to eight zones, you can manage all your audio requirements in one easy-to-use package. Besides superb background and foreground music throughout the hotel, you can make announcements, use the system for small conferences, meetings or parties, and customize the sound in the restaurant, bar and lounge.

The right type of background or live music can make or break a dining experience. In popular spots, a quality audio and voice announcement system that can be heard loud and clear in noisy bars, dining areas and waiting areas is essential to set the right mood as well to get the guests to their tables and keep the waiting list short. In a busy restaurant with different sections and dining rooms, this can be challenging. But not for the PLENA matrix. This stylish system packs enough powerful audio quality to hit exactly the right notes for the perfect dining experience.
