Specification Sheet

PA/VA Standards Compliance
Recent upgrades deliver the most comprehensive safety and
monitoring facilities available, making QFlex fully compliant in any
life safety environment. A new pilot tone detection feature enables
constant checking of the complete audio signal path and cable
integrity, meeting BS5839 requirements. Input switching can be
implemented should the pilot tone indicate primary input failure,
giving full system redundancy.
For larger QFlex networks, the Sentinel SM1 System Monitor
provides complete system-wide fault monitoring and reporting.
Built on a thoroughly proven processing platform, Sentinel
monitors the entire audio system as well as any controlling PCs,
reporting problems via relay contacts and indicating faults on the
front panel display complemented by an onboard alarm.
VNET Monitoring and Control
QFlex is fully compatible with Tannoy’s proprietory VNET monitoring
and control protocol, allowing QFlex loudspeakers to share the
same network as other VNET-compatible Tannoy loudspeakers
and subwoofers. Because VNET supports a free network topology,
loudspeakers may be linked in daisy-chain or star topologies, or any
combination of the two. The supplied VNET software program
supervises and controls all commissioning and performance
monitoring functions.
Comprehensive Connectivity
QFlex is designed to allow fast, direct and trouble-free interfacing with
virtually any type of audio system. Standard audio inputs are balanced
analogue, each with a loop-through link output. Analogue input
terminations are on installation-standard Euroblock plug-in connectors.
AES3 (AES/EBU) inputs are available on the QFlex using the optional
QFlex AES3 break-in interface that allows the VNET network and AES3
audio signal to share the same Cat-5 cable.
Also available is the Constant Voltage Interface, which steps down
the audio signal from 70 V/100 V to line level for direct connection to
a QFlex system. And, for the fully networked future, just one optional
Dante network bridge connects all QFlex systems in a zone to
Audinate’s Dante digital audio network.
BeamEngine GUI for Precise
Coverage Configuration
The intuitive BeamEngine GUI is a Windows™
based program that enables a system designer
to specify a target area and then generate a
steering algorithm tailored for optimum coverage
of that area. BeamEngine graphically represents
the sectional view (elevation) of the audience area
as well as the location and aiming angle of the QFlex
array. The resultant steering algorithm is saved and
loaded into the QFlex DSP via the VNET software.
For more resolute and comprehensive acoustical
simulations, the balloon DLL can be exported for
utilization in EASE or CATT Acoustic™ acoustical
modeling software programs.
