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
