Bosch Introduces New Release of Praesideo Public Address and Emergency Sound System
Bosch introduces new release of Praesideo Public Address and Emergency Sound System
New version increases design flexibility and leads to more optimal and cost-effective solutions
o Enhanced flexibility in system design
o Increased cost-effectiveness
o Broader application scope for medium and large sized projects
With the release of Bosch Praesideo SW Version 3.1 new additional hardware is introduced such as 4- and 8-channel Basic Amplifiers, a call stacker, a numeric keypad and a PC Callstation. These new devices will further enhance Praesideo's position in this competitive market by giving customers more flexibility in design and a more optimal and cost-effective solution. Praesideo is therefore ideal for medium and large applications such as shopping centers, schools, tunnels, multi-purpose sports stadia and airports.
Call Stacker
This stand-alone device is connected to the Praesideo system bus via two network connections only. The unit is used to record calls to occupied zones and automatically playback the recorded calls when the zones are free. The unit also offers the possibility of time-shifted broadcast of calls to eliminate acoustic feedback. Call stacking and time shifting are typically used at airports, in industrial plants and in offshore applications.
Numeric Keypad
The new numeric keypad is used to password protect call stations and for easy zone selection. The unit connects to standard Praesideo call stations and contains a numeric keypad and LCD with backlight. User access is via a user number and PIN code. An access lock is activated after a predefined time or by a so-called hot key when the user leaves the call station. Further zone selection functionality enables the user to make calls in predefined zones or zone groups.
PC Callstation
The new PC Callstation is a powerful tool to control medium and large size Praesideo systems via an open interface. The official Bosch supported software tool can control single as well as multiple Praesideo systems over TCP/IP.
A unique feature of the new callstation is a user interface that can be customized by the customer. A single server can handle multiple dedicated operator control panels. Functions such as predefined calls per user, status information per zone for running calls, activated Background Music (BGM) sources and settings are provided as standard.
Basic Amplifiers
The new Basic Amplifiers are rated 4 x 125 W and 8 x 60 W. They are high efficiency class-D amplifiers with built-in output transformers to drive 100 V and 70 V loudspeakers. Standard Basic Amplifiers are connected to the Multi Channel Interface; an analog line input is also available for low priority local audio.
The amplifiers provide overload protected connections for separate group A and group B redundant loudspeakers in a zone and can be configured for class-A loudspeaker loop wiring. The Basic Amplifiers feature a switch mode power supply with low inrush current and operate both on mains and 48 V battery power. Power supply and amplifiers are fully supervised. Stand-alone operation is possible. Last year Bosch introduced the 1 x 500 W and 2 x 250 W versions of the Basic Amplifier.
Praesideo Standard Amplifiers remain in the product range for applications which demand Digital Signal Processing functionality such as delay, equalizing or automatic volume control.
Audio over Internet Protocol
The demand for real-time audio transmission over long distances continues to grow. The new Bosch IP Audio unit is a unique solution for digital audio transmission between PA systems and remote locations. The IP Audio module is a full EVAC compliant solution for audio over local area networks and the Internet. It offers an analog audio microphone/line input and line output, and built-in supervised control inputs and outputs. The units are easy to install and are configured via a standard web browser.
TuV tested and certified
Praesideo Version 3.1 has been independently TuV tested to EN/IEC60849 certification for "Sound Systems for Emergency Purposes". This enables Bosch to assure not just installers but also fire departments, consultants/specifiers and end-users that the EVAC systems they are using comply with the strictest requirements of the EN/IEC60849 standard for public buildings.
