TANNOY QFLEX 8
Digitally Steerable Powered Column Array Loudspeaker
QFLEX 8
The QFLEX 8 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 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 8 has a classleading ±70° steering control, plus 8 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 8’s revolutionary BeamEngine technology steers 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 aesthetically-pleasing package.
Drivers, Power & DSP
The QFLEX 8 column array loudspeaker comprises eight 4″ full-range drivers, each with its own dedication 100-Watt Class D amplifier. QFLEX 8’s drivers provide digitally-steerable coverage for distances up to 20 m (66’). 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 8 is also an exceptional choice for multiple-column configurations consisting of other TANNOY VNET enabled products. 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 Add-Ons
A wide range of accessory options are available for the VNET-enabled QFLEX 8 including: The VNET ETHERNET INTERFACE; VNET USB RS232 INTERFACE; VNET2-AES INTERFACE, VNET INTERFACE POWER SUPPLY; VNET INTERFACE RACK MOUNT; as well as the QFLEX ISOLATOR, for eliminating potential ground/hum issues.
PA/VA Compliant
Engineered for the ultimate in reliability, QFLEX 8’s high level of voice intelligibility and telemetry functionality renders it fully compliant in any life safety or mass notification environment.
Build Quality
The architecturally styled aluminium enclosure is finished in a semi matt white paint with a corrosion resistant aluminium perforated grille. The QFLEX 8 includes the necessary hardware for quick and accurate installation. Mains input and output link power connectors are Neutrik powerCON.
