PRS-NCO3 Praesideo Network Controller Public address and emergency sound system control unit Control and routing of 28 simultaneous audio channels Ethernet interface for configuration, control diagnostics, and logging Digital storage for pre recorded messages EN 54 16 and ISO 7240 16 system certification
LBB 4401/00 Network Controller The LBB 4401/00 Network Controller unit is the heart of the Praesideo system. The unit is capable of routing up to 28 simultaneous audio channels, delivering power to the system (except for power amplifiers), fault reporting and controlling of the system. The audio inputs can be announcements from call stations, background music or local audio inputs. The network control unit can be configured for any complex public address configuration via the PC. The PC need not be connected permanently to the unit as it works independently from the PC. If a PC is connected to the network controller unit, all status changes in the system can be displayed through the configuration and diagnostic logging software, supplied with the unit. The unit can be free-standing on a tabletop or mounted in a 19" rack.
Praesideo Digital Public Address And Emergency Sound System There are four types of power amplifier units in the Praesideo product range. These differ in the number of amplifier channels per frame and the power ratings of the individual amplifier channels. The types of power amplifiers are as follows: LBB 4421/10 1 x 500 W Power Amplifier LBB 4422/10 2 x 250 W Power Amplifier LBB 4424/10 4 x 125 W Power Amplifier LBB 4428/00 8 x 60 W Power Amplifie The power amplifiers can be selected for 100 V, 70 V and 50 V output tapping. Audio input is provided via the fiber optic network cable. The power amplifiers are equipped with amplifier monitoring and change-over relays. The amplifier provides short-to-ground and short-circuit detection functions. If an end-of-line supervision card is plugged in, the loudspeaker lines are also monitored for open circuits. The pilot tone for the monitoring is generated in the power amplifier itself. The power amplifiers are equipped with audio processing facilities for each amplifier channel. It is possible to have 3 parametric equalizer sections and 2 shelving equalizers. The power amplifiers can be connected to the network line directly. Ambient microphone connection enables output level adjustment for maximum intelligibility. The power amplifier has a provision for connecting a 48 V DC backup power supply. The 48 V is protected against reverse polarity, and availability of the 48 V supply is continuously monitored.
Bosch Plena Booster Amplifier The Booster amplifiers are powerful power amplifier in a 2U high 19”case (3U housing for LBD 1938) for rack mounting or tabletop use. The Bosch booster amplifier series with its varied amplification range fulfills a wide variety of public address requirements at a surprisingly low cost. The amplifier is protected against overload and short circuits. The system has two balanced inputs with priority control, each with a loop-through facility. This makes it easy to connect remote systems that require priority control. An additional 100V line input is provided to connect the amplifier to a 100V loudspeaker line to provide more power to remote locations. The amplifier has 70V and 100V outputs for constant voltage loudspeaker systems, and a lowimpedance output for 8 ohm or 4 ohm loudspeaker loads. Specification :- Wide range of power amplifier 120w/240w/480w Multiple outputs - 70 V / 100 V and 8/4 ohm Temperature controlled forced front to back ventilation, directly stackable Mains, battery back-up, and pilot tone supervision Dual inputs with priority switching (LBD 1938) Excellent signal to noise ratio (> 90 dB) Models: LBD1930/00: 120W Plena Booster Amplifier LBD1935/00: 240W Plena Booster Amplifier LBD1938/00: 480W Plena Booster Amplifier
