2.0: INTRODUCTION

Tannoy has integrated the Dual Concentric“ point source, constant directivity drive unit with leading edge digital signal processing, network control and class D amplifier technologies to create VNET“. High definition sound reinforcement (HDSR“) loudspeakers designed to form the complete installation solution. Close integration and proximity of the main system elements has many advantages, and permits the amplifiers, processing, monitoring and drivers to perform as a unified whole. The resulting package is a very high performance loudspeaker with intuitive user setup, integrated processing, tuning control, performance diagnostics and protection. Class D power amplification with a switched mode power supply is very efficient, flexible and reliable. Little is required in the way of heat sinking and no fans are required. The small control panel on the rear of the cabinet is all the surface area that is needed for cooling, allowing the unit to operate at a low temperature, even when driven at very high power levels. The digital electronics (DSP) also use switched mode regulators to further improve efficiency and enhance design synchronicity of the entire package.

The Tannoy VNet Range of professional loudspeakers have been designed for a wide variety of sound reinforcement applications requiring extended frequency response from a powerful yet compact system, capable of delivering high sound pressure levels with extremely low distortion, resulting in outstanding clarity, definition and detail.

The Tannoy VNET12 comprises one 12 inch Dual Concentric driver, in which the low frequency (LF) and high frequency (HF) sources are coincidentally aligned to a point source, resulting in a smooth uniform frequency response over a wide area of coverage either as a portable stand alone system or in a multi-cabinet array. The sophisticated CAD designed waveguide

combines conical dispersion and excellent acoustic impedance characteristics. As the system is a point source, clusters and arrays have minimal lobing. These features are inherent and achieved without the use of any electronic signal processing.

2.0: INTRODUCTION

The Tannoy VNET12HP & VNET15 loudspeakers utilise high performance Dual Concentric“ drive units — the 12 (300mm) PowerDual“ and the 15 (380mm) PowerDual“. The substantially increased efficiency and power handling of these all-new driver designs ensures that the VNET12HP and VNET15 are capable of delivering high SPL s in even the most demanding applications. Like all Tannoy Dual Concentric loudspeakers the Tannoy VNET12HP and VNET15 exhibit true constant directivity, providing an even frequency response over the entire area of coverage. The output capability makes the Tannoy V12HP and VNET15 loudspeakers suitable for much larger audience sizes or venues requiring very high SPL s, such as nightclubs.

The VNET300 offers the ultimate in sound quality for critical applications such as theatre, acoustic music venues and houses of worship. For all applications where performance is the focus and the system should be so accurate that it reinforces, but remains unobtrusive and acoustically transparent to the audience, the VNET300 is the natural choice. The 12 SuperDual“ ensures the most even frequency response over a wide coverage area in the medium size venues for which the Tannoy V300 is designed.

The asymmetric cabinet profile of the VNet Products allows flexible and discreet installation. As a foreground system, installation is made simple with a range of Secur-ET mounting hardware, designed specifically for the V series — or the system can be flown using the integral M10 inserts. For portable stage use the birch ply cabinet has a recessed carrying handle on the rear of the cabinet and a blanking plate, which can be removed to install an optional pole mount. As a versatile low profile stage monitor, the conical coverage pattern gives the performer greater freedom of movement than allowed by conventional horn loaded designs.

The loudspeakers are factory calibrated for optimum individual performance; this way the user does not have to worry about whether they have input the correct speaker management settings, or have to painstakingly optimise dynamics.They can concentrate on room measurement and optimisation alone. The product is shipped with our VNET“ software package to facilitate easy on-site commissioning of the system. This intuitive Windows interface controls all of the critical install functions, as well as providing the interface for the ongoing monitoring of critical system status and performance data, all in real-time. Implementation of the network could not be simpler; VNET“ will support Free Network Topology , using twisted pair cable & RJ45 connectors. Each loudspeaker will contain a unique address so no user input will be required to configure the network nodes. Each loudspeaker in the system can be individually optimized and acoustically profiled, taking into account its exact position within the venue relative to the room boundary, and its own performance relative to the acoustic properties of the room itself.

The Tannoy VNET15BP is a compact, versatile subwoofer system, primarily designed to extend the low frequency response of the V series loudspeakers and increase system headroom. The VNET15BP will extend the frequency response of these systems to below 40Hz and is capable of providing output levels normally be associated with considerably larger enclosures. The VNET15BP comprises one high efficiency 380mm(15 ) drive unit. The cabinet is constructed from multiple-ply hardwood, which will survive the punishment that speaker systems are subjected to on the road and in club installations. The compact dimensions of the VNET15BP enable it to be used in permanent or portable applications without being obtrusive.

The Tannoy VNET15HL is a horn-loaded subwoofer with very high output capability designed to provide maximum low frequency impact.The tight and punchy sound of the VNET15HL adds depth and dramatic impact for a wide variety of sound reinforcement applications. This powerful loudspeaker is capable of delivering remarkable sound pressure levels with extremely low levels of distortion and power compression, while maintaining a uniform frequency response throughout its dynamic range.

The VNET15HL comprises one high efficiency 380mm (15 ) drive unit. The cabinet is constructed from multiple-ply hardwood, which will survive the punishment that speaker systems are subjected to on the road and in club installations. The compact dimensions of the VNET15HL enable it to be used in permanent or portable applications without being obtrusive.

The Tannoy VNET18DR is a direct radiating subwoofer designed to compliment Tannoy VNET loudspeakers where high definition sound reinforcement at low/ultra low frequencies with increased headroom is required. The VNET18DR extends the frequency response of systems to below 30Hz, making it ideal for club, theatre and concert sound applications. This powerful loudspeaker is capable of delivering high sound pressure levels with extremely low distortion and power compression while maintaining a uniform frequency response throughout its dynamic range. The VNET18DR comprises one high efficiency 457mm(18 ) drive unit. The cabinet is constructed from multiple-ply hardwood, which will survive the punishment that speaker systems are subjected to on the road and in club installations.

VNET subwoofers feature recessed carrying handles and blank plate for a top-mounted stand socket, which serves as a base for locating the main full range or mid/high speakers in the air. By using 35mm tubing the need for a tripod stand can be eliminated.

3.0: UNPACKING AND VISUAL CHECKS

Every Tannoy VNET“ product is carefully tested and inspected before being packaged and leaving the factory. After unpacking your loudspeaker, please inspect for any exterior physical damage, and save the carton and any relevant packaging materials in case the loudspeaker again requires packing and shipping. In the event that damage has been sustained in transit notify your dealer immediately.

3.1: PRELIMINARY RECOMMENDATION

A word of warning on high sound levels - these speakers are capable of generating high output levels over sustained periods of time and such levels, over 95dBspl for 8 hours per day, can eventually cause permanent hearing loss. Since Tannoy loudspeakers have a natural-sounding flat frequency response and low distortion, it’s possible not to be aware just how high the sound level is high while working with them.

For continuous exposure we recommend the occasional use of a sound level meter. This should be capable of integrating the sound level over a period of exposure according to noise control standards and used just to check that noise levels are always within safety limits.

5.0: OPERATION

The range of products are fully integrated designs, all speaker management functions which include driver EQ, dynamic limiting, & crossover functions are carried out within the DSP, therefore the need for external amplification, active crossovers and limiters is not required. The only input from the user is crossover between full range cabinets & subwoofers, and room equalization (if necessary).

When routing audio, units may be daisy chained together by linking the Input/link XLR connectors. It is necessary to have power local to each speaker, as it is not possible to daisy chain the AC power connectors.

5.1: AC POWER REQUIREMENTS

AC Power Requirements

VNET“ products are equipped with Neutrik Powercon“ mains connectors which mate with the Neutrik NAC3FCA Cable connector, quick lock with a securing lever for power-in. This AC mains connector is supplied with each VNET“ product. The amplifier operates between the ranges of 100 to 240 Volts; the auto ranging power supply detects the mains voltage automatically and configures accordingly. Replace the mains fuse only with the same T10A HBC type supplied by Tannoy under part number 3461 0919.

5.2 COOLING

Do not install this equipment in an enclosed space. Do not limit free ventilation and movement of air around the back panel. Ensure that there is at least 100mm (4") of space around all sides of the product for ventilation. An efficient switch mode power supply has less weight, less current draw and more efficient mechanical cooling; meaning that no fans are required. In an area with a relatively high ambient temperature the heatsink can reach temperatures of up to 65 degrees C, this is perfectly normal.

5.3 LED FUNCTIONS

On switch on all of the LED s will illuminate instantaneously. The first to go off is the green signal LED after about 1 second. The red limit LED will flash for 5-10 seconds, this is the unit performing a self diagnostic test. During this initial few seconds the audio is muted until the red LED stops flashing & the blue power LED is the only LED left illuminated.

After the self diagnostic test is performed, the unit is ready to pass audio. When audio is detected the green signal LED will illuminate. If at any time the Red LED flashes this indicates that the DSP is taking corrective action by applying limiting to either the LF or HF channels (or both). Regular flickering of the Limit LED is perfectly acceptable; do not allow the limit LED to stay on constantly for any sustained length of time (reduce the gain).

Fast regular flashing of the red LED indicates that the DSP is taking protective action; the input will be automatically attenuated to avoid over driving, if this occurs the operator should reduce the input gain from the source. If the gain is not reduced the unit will eventually be shut down by the DSP.

The blue Network Find LED on the front of the cabinet (behind the grill) can only be illuminated by activation from within the software interface. When activated the LED will flash intensely as an aid to locate and identify loudspeakers connected on the network. The red limit LED on the back panel also doubles as a network find LED duplicating the function of the blue front mounted LED.

5.4 LIMITERS

The limiters are carefully set-up to preserve the loudspeakers dynamic headroom by allowing short term transients to pass; audible degradation in sound will only become apparent when the limit indication is on constantly. The limiting functions will protect the amplifier from long term overheating by attenuating the driving voltage to the drive units. If used irresponsibly (constant hard clipping) sound quality will be compromised. In extreme cases drive units may also be damaged.

5.5: AUDIO CONNECTIONS

Audio Connections

The signal input & link connectors are fully balanced. SIGNAL XLR CONNECTOR When connecting a balanced signal be sure to wire Hot (+) Pin 2 to the following standard:- Cold (-) Pin 3

Shield (GND) Pin 1

In a standard balanced interconnection there are two signal conductors and a shield. The shield is normally referenced to ground at one or both ends.˚ Many times the shield is lifted at one end, usually at the input to eliminate "ground loops" or noise.˚The problem with this approach is that while it may reduce hum, the shields act as radio antennas and pickup radio frequency interference from the environment.˚

Multiple enclosures may be driven from a single audio source; simply plug the signal source output into the first XLR input socket, and patch that speakers XLR link to the next speakers XLR input socket & so on.

5.6: USER DSP ON/OFF

A user DSP On/Off switch is provided on the amp panel. This miniature switch is recessed and can be easily activated with a small screwdriver.

The switch in the OFF position will return the VNET“ loudspeaker back to the original factory settings, this basically means that any parameter edited in software (EQ, Crossover, Mute, Delay) can be defeated by activating this switch. This can be a very useful feature. Example:-

In a large corporate production the networked loudspeakers are been used by an operator who has been using the Podware software for editing EQ & gain & delay; at the end of the performance he mutes the loudspeakers from within the software and the loudspeakers are returned to hire stock after the performance. Next day there is a rush for a small hire comprising only a couple of VNET“ loudspeakers. The speakers are taken to the small gig where the operator is not making use of the Networking, or Podware software in this particular instance. He realizes that he muted the loudspeakers the night before, and this particular pair had 100ms of delay applied!! All he has to do is flick the USER DSP switch to the OFF position (assuming he is carrying his Leatherman) and any of the USER editable parameters in Podware are defeated.

6.0: NETWORK CONNECTIONS

Interconnection between the network computer and the speakers is very straight forward, using twisted pair cable and simple connectors. The RS485 interface operates on a shared bus so that a single computer can control any amplifier on the bus, and the computer may gather status information from any device on the bus. Each module contains a unique address so that no user input will be required to configure network nodes.

It is only data that is carried over the network to control setup functions & ongoing system diagnostics, therefore if a network fault occurs, audio can still be delivered. This alleviates the problem of total system failure through a single system controller going down. As each loudspeaker controls it own DSP functions any unforeseen failure would be isolated to only that particular

node .

RS-485 is standard for sending serial data. It uses a pair of wires to send a differential signal over distances up to 4000 feet (1200m) without a repeater. The differential signal makes it very robust, RS-485 is one of the most popular communications methods used in industrial applications where it s noise immunity and long-distance capability are a perfect fit.

IMPORTANT: Always run a signal ground with RS-485

Connection from the PC to the network is via a 3 available from your IT supplier. At the time of writing this manual extensive testing was carried out with the following devices:-

Tannoy USB — RS485 Converter (Part No. 8001 3920) K2 from KK (www.kksystems.com) USB-COMi from Easysync (www.easysync.co.uk) 485 SD9R from B&B electronics (www.bb-elec.com)

Connections from the RS485 device to the speaker is as follows:-

From RS485 Device RJ45 To Vnet Network

B+ Pin 1 A - Pin 2 GND Pin 5

Network connections between nodes are via rugged Neutrik ethercon connectors; these are high quality and are compatible with standard RJ45 plugs. Node connections are made using standard RJ45 connectors and CAT5 cable. Long runs should be solid core, but standard is fine. The implication is that stranded is more robust and less prone to breakage, it is therefore suggested that solid should be used for install applications while stranded is better suited to rental applications. Cabinets can be daisy chained or linked in a star configuration, or a combination of both. Quality termination of all connectors at each node is essential for the network to function correctly.

6.1 LINKING CABINETS

The table below shows the standard straight-through convention for CAT5 patch cables (clip down) . These can be used between network nodes. Bear in mind though that only Pins 1, 2, & 5 are used to link the network together.

1 V 1 White/Orange 2 V 2 Orange 3 V 3 White/Green 4 V 4 Blue 5 V 5 White/Blue 6 V 6 Green 7 V 7 White/Brown 8 V 8 Brown

To aid the construction of very large networks each speaker provides a source of power (+12Volts) on the network Link connector that can be used to seamlessly power network extenders or repeaters that large networks may require. This power can be located on pin 4 on the NETWORK LINK connector. This power is passed between the NETWORK IN & NETWORK LINK connectors if the speaker is powered off to ensure that upstream net powered devices continue to receive power.
