Tannoy has developed the QFlex Life Safety (LS) models as a cost-effective solution for critical, life safety applications, a solution that balances complex power consumption needs with the high performance and intelligibility that is the core of the proven QFlex range. Based on Tannoy's superior knowledge and heritage of speech intelligibility in critical listening in difficult acoustic environments, the new models have an optimised driver placement and improved current draw, making them perfect for applications where emergency voice alarms or communications may be required.
The QFLEX 16LS-WP 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 centers, conference facilities, shopping malls, performing arts centers and museums. Certified for water and dust ingress protection to IP54 standard, QFLEX 16LS-WP is an exceptional choice for indoor swimming pools and areas with unusually high levels of dust or moisture, as well as outdoor applications where weather conditions are moderate. 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.
The new QFlex 16LS column loudspeaker is designed primarily for large transportation hubs as part of a PA/VA system where speech is the main audio source, either from live announcements or via a pre-recorded message. These new QFlex life safety models are specifically intended to optimise voice reinforcement, and as a result, make them more affordable, and therefore applicable, to a wider range of projects.
The QFlex 16LS makes use of a fewer number of wider bandwidth 4-inch low-frequency drivers than the equivalently sized QFlex 40 model to achieve an emphasis on the speech band only, over an effective distance of up to 70 meters. Each of the 16 drivers is controlled by its own discrete channel of 100 Watt (RMS) Class D amplification and cutting-edge DSP, the reduced driver count and wider spacing enabling a 50% reduction in power consumption. The QFlex 16LS provides a beam steering range of ±40 degrees with effective low-frequency control down to 230 Hz. Dispersion is nominally 120 degrees horizontal and a vertical range of between 5 degrees and 100 degrees, either symmetrical or asymmetrical.
