TANNOY Vnet™ 15BP ลำโพงซับ Subwoofer
The active, DSP controlled and networkable VNET 15BP is a compact, versatile and extremely efficient bandpass subwoofer system, designed to extend the low frequency response of Tannoy VNET™ Series loudspeakers and increase system headroom and providing output levels normally associated with considerably larger enclosures.
The Tannoy VNET 15BP consists of one high efficiency 380mm (15.00”) with a 76mm (3.00”) voice coil drive unit mounted in a compact and sturdy, black or white painted cabinet constructed from 15mm (5/8”) multi-ply birch hardwood; robust enough to survive the punishment that speakers systems are subjected to on the road and in club installations.
VNET™ supports free network topology so cabinets can be arranged in a daisy chain, linked in a star configuration or in any combination of both. Implementation of the network could not be simpler, with connections between nodes via high quality rugged Neutrik Ethercon connectors, which are compatible with standard RJ45 plugs, and CAT5 cable. Each VNET™ module contains a unique address so that no user input will be required to configure network nodes.
The compact dimensions enable the VNET 15BP to be used without being obtrusive in applications as diverse as live sound reinforcement, theme pubs and nightclubs, theatre front of house and effects, movie theatres and cinemas, side fill in large scale music reinforcement, theme parks and leisure venues, sports and multi-use stadiums, audio visual, high quality public address and houses of worship.
System commissioning and ongoing venue network control, incorporating real time diagnostics of electronics and drive unit, are all managed by the exclusive VNET™ software package. Supplied with each unit, this intuitive Windows tool controls all of the critical install, commissioning and performance monitoring functions.
The VNET 15BP comes complete with recessed carrying handles for ease of transportation and 10mm flying points provide a quick and secure flying. A blanking plate covers a recess for the optional VTH pole mount, so tripods can therefore be eliminated by connecting VNET™ subwoofers and Dual Concentric™ full range loudspeakers with the Tannoy VTH top hat mounting hardware and a pole.
Networking
The RS485 interface is used for the serial data, using a twisted pair to send and receive information to a high number of nodes over very long distances. Operating on a shared bus system, so that a single computer can control any node on that bus, also means that status information can be gathered from any of the devices. This differential signal is very robust, while RS-485 is one of the most popular communications methods used in industrial applications where its noise immunity and long-distance capability are a perfect fit.
As only data to control setup functions and ongoing system diagnostics is carried over the network and each VNET™ loudspeaker controls its own DSP functions, any unforeseen problem would be isolated to only that particular node and audio will still be delivered.
Speakers identified on the network set up screen have factory default names, which can be edited by the user to reflect their actual location on the network. They can be physically located on the network by selecting the Flash function to activate an LED mounted on the front of the loudspeaker.
The loudspeakers are fully calibrated at the factory, avoiding the need to input the correct speaker management settings or dynamics at the point of install. This frees the installer to concentrate instead on room measurement and system optimization.
