The QFlex 48 can be used as a standalone self-powered column array device for both spoken word and full-range musical applications in larger scale spaces, where high intelligibility and minimal visual impact are driving concerns.
QFlex is a range of digitally steerable, multi-channel, array speaker systems for the professional install market. QFlex is designed as a complete solution for applications with difficult acoustics, such as houses of worship, transportation hubs, convention centres, conference facilities, shopping malls, performing arts centres and museums.
QFlex is quite revolutionary in that it is able to achieve even coverage and SPL which is maintained across the listening plane. QFlex is able to create an asymmetrical pattern which allows similar SPLs both in the near and far field. It is able to steer the beam away from surfaces that cause reflections to frequencies beyond 12 kHz, making it the first digitally steerable array to maintain music quality over the desired area of coverage, all in a very architecturally pleasing package.
The intuitive BeamEngine GUI allows the designer to specify target areas. Based on those target areas a steering algorithm is generated and tailored for that specific area, rather than having to choose from a limited palette of opening and steering angles.
New features introduced on QFlex deliver more resolute safety and monitoring facilities, making it fully compliant in any life safety or mass notification environment. In addition QFlex has been weatherised for outdoor or harsh environments without compromising on the product’s sleek aesthetic, making it perfectly suited for large scale transport hub applications such as within airport terminals and major train stations. Among the key improvements on this front are the addition of Pilot Tone Detection capability, Sentinel SM1 System Monitor and certification to IP53 standards.
Pilot Tone Detection
An external pilot tone can be used to check the integrity of the cabling and audio signal path between the source and each QFlex loudspeaker, meeting any requirement of BS5839. Presence of the pilot tone can be checked in software or hardware. Input switching is also possible, should the primary input fail (pilot tone not detected), giving full system redundancy.
Sentinel SM1 System Monitor
For large networks, Sentinel System Monitor provides a complete system-wide fault monitoring and reporting solution for mission-critical applications. Built on a tried and trusted processing engine, Sentinel keeps a watchful eye on the audio system, and if required, any controlling PCs. Problems are reported both via relay contacts to the main monitoring panel in your system as well as being shown on Sentinel’s front panel display. Multiple Sentinels can even monitor each other and the same network simultaneously for systems that require dual-redundant monitoring.
System connectivity has also been greatly enhanced with QFlex now being capable of receiving and transporting digital audio via AES3 stream over long distances. A new VNET/AES break-in interface is available from Tannoy, allowing the VNET network and AES3 to be transported on the same CAT5 cable.
QFlex has been certified for water and dust protection to IP53 standard by leading test house, Intertek. This offers complete protection from the amount of dust that would interfere with the operation of the equipment and protection from sprayed water, and since the QFlex enclosure is constructed entirely from aluminium, corrosion is not an issue.
Constant Voltage / 100 V Interface
For applications utilising existing front end constant voltage systems, a new 100 V interface is available, allowing for integration into existing constant voltage systems by stepping down signal from 100 V / 70 V to line level.
All of these improvements are now available as standard with any QFlex system, except the constant voltage step-down interface and AES break-in interface which are customer specified options. These additional features reinforce the product’s position as the market-leading steerable loudspeaker solution.
The QFLEX 48 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.
While many competing steerable arrays allow only a modest steering range across specific frequencies, the QFLEX 48 has a class-leading ±70° steering control, plus 40 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 48’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 aesthetically pleasing package.
Drivers, Power & DSP
The QFLEX 48 column array loudspeaker comprises 16 x 4" low frequency drivers, 16 x 3" low frequency drivers and 16 x 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 48’s drivers provide digitally-steerable coverage for distances up to 80 m (262') – with no aliasing artifacts. A robust internal DSP engine works seamlessly with the proprietary VNET and BeamEngine software, both of which are available for free download here.
