Tannoy VQNET 40DF Specification Sheet

VQNET 40DF

Product Description

Integrated with cutting edge digital signal processing, network control and dual channel
Class D amplication, the VQNET 40DF (40x40), is a very high output down ring Mid/
High loudspeaker system designed for applications requiring high impact sound
reinforcement with class leading pattern control. The modular design approach allows
the sound system designer to create seamless and predictable arrays, or they can be
used singly as part of large distributed systems. VQNET 40DF addresses the
requirement for compact dimensions without compromising performance in any way.

VQNET MH elements which are available in various patterns will integrate seamlessly
with the VQNET DF enclosures to facilitate tight pack arrays; the compound angles on
the enclosure avoid unsightly spaces between separate cabinets when arrayed
horizontally VQNET MB or VS 15DR elements can be added to extend bandwidth and
pattern control to lower frequencies.

Horn design involves balancing compromise…..until now.

Our unique approach in keeping what is effectively a Dual Concentric behind a single
horn gives us many performance advantages. Performance of the VQNET 40DF in
terms of accuracy & sound quality is second to none. The VQ horn design principles
provide denitive and measurable advantages over multiple-horn and co-axial designs.

Each VQNET 40DF incorporates a unique driver technology to radiate a coherent single
point source for superior dispersion control when coupled to a PSW™ (Point Source
Waveguide). This advanced design aligns the acoustical centres of the transducers
providing a single coherent wavefront emanating from the throat. The PSW™
waveguide achieves an optimum balance of extremely well controlled coverage,
smooth frequency response, and natural sound character.

The modular approach of ampliers, processing, monitoring and drivers designed into
each loudspeaker enables acoustic optimization for the speaker to perform as a unied
whole.The intuitive setup software, integrated processing, tuning control, performance
diagnostics and protection produces an easy to install and exceptionally high perform­ance networkable loudspeaker.

For outdoor applications, weather resistant enclosures which incorporate stainless steel
hardware are available.

VNET™ Network

Each VQNET DF enclosure is fully VNET™ compliant.
VNET™ supports free network topology so that the
loudspeakers can be arranged in a daisy chain, linked in a
star conguration or in any combination of both.
Implementation of the network between nodes is via high
quality rugged Neutrik Ethercon connectors, which are
compatible with standard RJ45 plugs, and CAT5 cable.
Each speaker has a unique address for auto-location on
the network. System commissioning and ongoing 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 critical install, commissioning
and performance monitoring functions.

Features

• “PSW™ Waveguide” - Point source design
(Patent applied for).

• Excellent Phase Coherence

• Perfect time alignment without the associated problems

of multi source interference

• Compact Dimensions

• Class leading directivity characteristics

• Extremely high sensitivity, therefore high SPL’s can be
achieved with a very modest amount of amplier power

• Exceptional transient response

Applications

• Large Houses of Worship

• Large Corporate AV applications

• Stadiums & other Sports facilities

• Dance Clubs

• Live sound – concert halls, theatres,
open-air venues

VNET SOFTWARE

VNET™ SOFTWARE_

The loudspeakers are fully calibrated at the factory, avoiding the need to in put the correct speaker
management settings or dynamics at the point of install. This frees the installer to concentrate instead
on room measurement and system optimisation. 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. A standard wireless LAN-to-serial bridge
can be used to communicate with the network, allowing the commissioning engineer to sit in the
auditorium communicating from a laptop on 802.11b

MONITORING & TELEMETRY FUNCTIONS_

During normal operation the speakers on the network will appear as minimised panels in the form of a
status monitor icon (Monicon) on the computer screen. These are laid out to reect the physical layout
of the speakers within the venue so that the user can monitor system status and component condition
at a glance. The minimised panels can be expanded to reveal highly detailed information in real time:

• Input clip indicator

• Two output limiter bar graph meter

• Heat sink temperature bar graph meter

• Amplier clip indicators (HF & LF on full range units)

• Transducer Failure Indicators (HF & LF on full range units)

• Amplier protect status indicator

VNET™ Software Features

The on-screen control panel for each device in the network has a properties tab consisting of the following:

• Model Name is factory set with product model name

• Network Handle (read only) is a numerical value set at the time of manufacture to uniquely identify
the device on the network

• Device Name is the specic user dened name, such as ‘Stage.Left’ or ‘Delay 1’

• Firmware Version (read only) is a numerical value of rmware version running in the device

• Conguration Name is the 12 character name the user can dene to describe the current settings
(such as ‘Live Mode’)

• Current ‘Voice’ prole indication (read only) is a numerical value indicating the current speaker
‘voicing’ prole (the factory set equalization, crossover, & dynamics functions)

• Software le loader in VNET™ allows a future modication to the software to be uploaded,
such as a ‘voicing’ change or revised control software with new features

• Record of any temperature or current shutdowns

• Record of the number of power cycles

• Rolling four day bar graphs recording amplier temperature and any dynamics applied

Signal Processing

• Gain Section: input gain fader with edit box (-30 to +15dB in 0.2dB steps)

• Input Mute: On, Off

• High-Pass Filter section: frequency spin / edit box and shape drop-down box

• Low-Pass Filter Section: frequency spin / edit box and shape drop-down box

• Equaliser Section: high resolution input EQ curve display

• Low Shelf Band: frequency spin / edit box, slope spin / edit box and boost-cut / edit box

• High Shelf Band: frequency spin / edit box, slope spin / edit box and boost-cut / edit box

• Parametric EQ Bands (x 8): frequency spin / edit box, slope spin / edit box and boost-cut / edit box

• Delay Section: delay spin / edit box (up to 180ms)

POWER INLET

The processor has a switch mode power supply that is capable of
operating with a nominal mains voltage of 85V to 240V, 50/60Hz without
re-configuration.

V

NET™ NETWORK PORTS

The network enabled V

NET SC1 controller features two network ports for

connection to any V

COMMUNICATIONS PORT CONNECTOR

Tannoy V

NET SC1 processors may be controlled entirely from a PC

running V

NET™ software using this RS232 serial port connector. This port

is also used for updating the firmware in the unit.

SECURE MODE SWITCH

A momentary button is fitted behind the rear panel, between the output
XLRs and the RS232 port. When activated, this will disable all the front
panel controls so they cannot affect the signal path, making the unit
secure against tampering.

AUDIO OUTPUT CONNECTORS

The processed outputs are impedance balanced.

AUDIO INPUT CONNECTORS

All audio connections are fully balanced.

operating with a nominal mains voltage of 85V to 240V, 50/60Hz without
re-configuration.

V

NET™ NETWORK PORTS

The network enabled V

NET SC1 controller features two network ports for

connection to any V

NET™ system.

COMMUNICATIONS PORT CONNECTOR

Tannoy V

NET SC1 processors may be controlled entirely from a PC

running V

NET™ software using this RS232 serial port connector. This port

is also used for updating the firmware in the unit.

SECURE MODE SWITCH

A momentary button is fitted behind the rear panel, between the output
XLRs and the RS232 port. When activated, this will disable all the front
panel controls so they cannot affect the signal path, making the unit
secure against tampering.

AUDIO OUTPUT CONNECTORS

The processed outputs are impedance balanced.

AUDIO INPUT CONNECTORS

All audio connections are fully balanced.
