NEW TANNOY QFLEX FOR LIFE SAFETY
Tannoy has added new models to its QFlex range of digitally steerable, multi-channel, column array loudspeaker systems, engineered as optimised solutions for life safety applications.
The new QFlex Life Safety (LS) models are a cost effective solution that balance complex power consumption needs with high performance and intelligibility, the company says. Optimised driver placement and improved current draw make them ideal for applications where emergency voice alarms or communications are required.
The QFlex 16LS and QFlex 32LS speakers 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.
The QFlex 16LS uses less 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 70m. Each of the 16 drivers is controlled by its own discrete channel of 100W (RMS) Class D amplification and cutting edge DSP, with the reduced driver count and wider spacing enabling a 50 per cent reduction in power consumption.
The larger 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 100W (RMS) Class D amplification and DSP.
“We determined that full-range beam-steering would be a prerequisite from the outset rather than placing emphasis only on vocal regions as with other solutions,” says product manager Stuart Archibald. “Life safety, however, is governed by a different set of rules and requires a different approach to the design of the loudspeaker system. In these critical applications power consumption is a key concern and therefore uninterruptible power supplies must operate effectively as part of the evacuation systems.”
The QFlex models interface with virtually any type of audio system, offering balanced analogue inputs and links on Euroblock connectors as well as AES3 inputs, plus network and control connections including Tannoy’s VNET monitoring.
