The microphone is high quality, durable, and phantom powered.
This document provides information on the LBB 9600/20 condenser handheld microphone from Bosch. It is a unidirectional microphone intended for use in public address and sound reinforcement applications. Key features include a condenser transducer, low sensitivity to noise and vibrations, and phantom power supply. Accessories such as extension cables, stands, and mounts are also available.
The LBB 1949/00 is a high-quality gooseneck condenser microphone with a flexible stem that runs on phantom power. It has a unidirectional pickup pattern and includes a 2m cable and lockable connector. The microphone can be mounted on floors, lecterns, or desktops using its threaded base and included adapter. It has a sliding on/off switch and priority contacts for remote control.
The LBC 1215/01 Microphone Clamp is a quick-release, spring-loaded microphone holder that can be screwed onto stands with 3/8", 1/2" or 5/8" threads. It holds microphone stems measuring 19 to 32 mm in diameter and allows for friction angular adjustment. The clamp weighs 60 grams and has a matte black color. It is compatible with Bosch hand-held microphones.
The document summarizes a unidirectional handheld microphone made by Bosch. It has a dynamic transducer element, cardioid directivity, and rugged construction. It can be used either handheld or stand-mounted. It is intended for use in applications like shops, restaurants, and leisure centers to provide affordable public address solutions.
The document summarizes a range of Bosch volume controls and program selectors for public address systems. It describes the different models, their power ratings and features like failsafe operation. Diagrams show dimensions and wiring. The controls allow adjusting sound levels or selecting programs, and ensure emergency announcements are heard at a preset level.
The document provides information on Bosch volume controls and program selectors for public address systems in Japan. It describes the LBC 14x2/x0 volume controls, which come in 12W and 36W versions and power-save or failsafe options. It also describes the LBC 1434/10 program selector, which allows selecting between 5 channels. The components comply with international safety standards and have applications in both announcements and background music distribution in public settings.
The document summarizes Bosch's LBC 14x2/x0 Japanese Volume Controls and LBC 1434/10 Program Selector. The volume controls come in 12W and 36W versions and can be configured for power-saving or fail-safe operation. The program selector allows selection of up to five audio channels. Both products comply with international safety standards and provide simple installation, operation, and reliability for public address systems.
The document summarizes a range of Bosch volume controls and program selectors for public address systems. It describes the different models, their power ratings and features. The volume controls come in 12W, 36W and 100W versions and can be configured for power-save or fail-safe operation. The program selector allows selecting between five programs. Technical specifications and ordering information is also provided.
The PRS-SWCS PC Call Server and PRS-SWCSL PC Call Server NCO Client allow control of multiple Praesideo network controllers and connected clients over TCP/IP. The PRS-SWCS PC Call Server controls user access and call functions, while the PRS-SWCSL extends licensing to additional network controllers. Configured views, predefined calls, and audio connections between networks can be set up through the included configuration client.
The Praesideo software allows users to configure and monitor a Bosch communications system through a web-based interface. It includes configuration, diagnostic, and file transfer software. The configuration software can be accessed at different privilege levels and is used to define system parameters, call macros, zones, equipment settings, and more. The diagnostic software logs events and fault information for monitoring the system status. File transfer software manages uploading and downloading files to the network controller.
The network splitter provides two branches from the main cable run to feed power and network connections to Praesideo units. It supports redundant network connections, can supply power from an external source, and has indicators for power and fault status. The splitter inserts units into the main network without redundancy but allows separate selection of current for each tap-off.
The PRS-FIN, PRS-FINNA, and PRS-FINS fiber interfaces connect glass fiber optic cable to plastic fiber optic cable within Praesideo communication systems. They convert between the cable types and support redundant network connections. Each interface provides power and status indicators and includes two control inputs, except for the PRS-FINNA which lacks a network address and control inputs.
The document appears to be a price list from Sathit A.V.L.Supplies Co.,Ltd. for microphones, wireless microphone systems, mixing amplifiers, loudspeakers and other audio equipment. It includes product codes, descriptions, and prices excluding VAT for various microphones, mixers, amplifiers, loudspeakers and other audio equipment.
The numeric keypad connects to a call station to allow for user access and zone selection via a 12-button keypad. It receives power from the call station and can be combined with up to 15 other keypads. The LCD provides feedback to the user about their selections and the system status. It has a flat cable connection and mechanical mounting to the call station.
The PRS-CSI is an interface that connects a remote call station to a Praesideo network via CAT-5 cable up to 1 km. It is powered by the network or a local power supply and includes two supervised inputs, built-in audio processing, and full supervision of the unit. The interface connects a single remote call station and supports high quality audio transmission with fail-safe emergency calling capabilities.
