QFLEX 24
Digitally Steerable Powered Column Array Loudspeaker with 24 Independently Controlled Drivers, Integrated DSP and BeamEngine GUI Control for Installation Applications
Description
QFLEX 24
The QFLEX 24 is a powered, digitally steerable multi-channel, column array loudspeaker designed as a complete solution for installed applications with challenging acoustics, such as houses of worship, transportation hubs, convention centres, conference facilities, shopping malls, performing arts centres and museums. The heart of the system is our proprietary VNET loudspeaker networking platform, which comprises both software and hardware DSP components that produce extremely-high speech intelligibility, impactful music reinforcement, and complete loudspeaker system diagnostics and monitoring.
Class-Leading Control
While many competing steerable arrays allow only a modest steering range across specific frequencies, the QFLEX 24 has a class-leading ±70° steering control, plus 24 channels of integrated DSP and amplification for consistent and highly intelligible full-range voice and music applications.
A Revolution in Sound Technology
The first digitally steerable column array loudspeaker of its kind, QFLEX 24’s revolutionary BeamEngine technology steers the the full-range sound away from surfaces that cause reflections. The intuitive BeamEngine GUI allows the designer to specify target areas. Rather than only providing a limited palette of opening and steering angles, the BeamEngine GUI generates a steering algorithm that is tailored for that specific area. The resulting asymmetrical pattern delivers similar sound pressure levels (SPL) in both the near and far field for superb coverage and intelligibility – all in a very aestheticallypleasing package.
Drivers, Power & DSP
The QFLEX 24 column array loudspeaker comprises eight 4″ low frequency drivers, eight 3″ low frequency drivers and eight 1″ high frequency drivers, each with their own individual 100 Watt Class D amplifier and integrated cutting edge DSP. Presented in a high density array with proportional frequency spacing, QFLEX 24’s drivers provide digitally-steerable coverage for distances up to 40 m (131’) – with no aliasing artefacts. A robust internal DSP engine works seamlessly with the proprietary VNET and BeamEngine software, both of which are available for free download here.
Scalability
Designed to provide premium-grade performance as a standalone self-powered column array, QFLEX 24 is also an exceptional choice for multiple-column configurations consisting of other TANNOY VNET enabled products. Implementation of the network between nodes is via highquality 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 Add-Ons
A wide range of accessory options are available for the VNET-enabled QFLEX 24 including: The VNET ETHERNET INTERFACE; VNET USB RS232 INTERFACE; VNET2-AES INTERFACE, VNET INTERFACE POWER SUPPLY; VNET INTERFACE RACK MOUNT; SENTINEL SM1, for monitoring VNET networked PA/VA systems, as well as the QFLEX ISOLATOR, for eliminating potential ground/hum issues.
PA/VA Compliant
Engineered for the ultimate in reliability, QFLEX 24’s high level of telemetry functionality renders it fully PA/VA compliant for use in any life safety or mass notification environment.
Build Quality
The architecturally styled corrosion resistant aluminium enclosure and perforated grille are finished in a semi matt white paint. The QFLEX 24 also includes the necessary custom mounting hardware for quick and accurate installation. Mains input and output link power connectors are Neutrik powerCON.
