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 32LS column loudspeakers are 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 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 32LS contains a combination of 4-inch and 3-inch low frequency drivers, distributed over the equivalent length of the QFlex 48, and an eight-way tweeter array of 1-inch drivers. Each driver is individually powered by one of 32 discrete channels of integrated 100 Watt (RMS) Class D amplification and DSP.

The QFlex 32LS offers a horizontal dispersion pattern of 120 degrees and a vertical range of between 5 and 100 degrees, along with a beam steering range of ±70 degrees. Low frequency control is effective down to 200 Hz even with the fewer number and increased spread of drivers that are required for the power saving essential in the life safety environment.


A new member of the 3rd generation sarc digital signal processors is used to perform sophisticated processing for all QFlex's sixteen channels.


Each QFlex module incorporates 8 or 16 channels of high performance amplification.


The optional standalone sentinel SM1 system monitor provides complete system-wide fault monitoring and reporting for mission-critical applications.


The Windows based BeamEngine GUI generates beam steering algorithms for precise audience coverage.
