Product Description

Integrated with cutting edge digital signal processing, network control and dual channel Class D amplification, the VQNET 40DF (40x40), is a very high output down firing 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 definitive 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 amplifiers, processing, monitoring and drivers designed into each loudspeaker enables acoustic optimization for the speaker to perform as a unified 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 configuration 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.

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 reflect 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:

• Transducer Failure Indicators (HF & LF on full range units)
• Amplifier 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 specific user defined name, such as 'Stage.Left' or 'Delay 1'
• Firmware Version (read only) is a numerical value of firmware version running in the device
• Configuration Name is the 12 character name the user can define to describe the current settings (such as 'Live Mode')
• Current 'Voice' profile indication (read only) is a numerical value indicating the current speaker 'voicing' profile (the factory set equalization, crossover, & dynamics functions)
• Software file loader in VNET™ allows a future modification 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 amplifier temperature and any dynamics applied
