Flying frames are avail able for use with the TQ-308DP, TQ-310DP and TQ-445DP. These enable
the cabinets to be installed in semi-permanent applications with the maximum of security. They
provide considerable variation of horizontal and vertical inclination, including upward angles, and
is very easy to re-position and angle once rigged. Optional scaffold clamps and pole adapters are
additionally available.

Permanent Installations
Any installation, whether temporary or permanent, must be securely attached to the structure of
the building using chain, steel wires or web straps which are certified and load rated for the
purpose. The combined weight of the sound system, its cables and the rigging system must be
safely carried by the points at which attachment is made to the building or structure. Great care
must be taken in selecting the attachment points and methods, being absolutely sure of the load
carrying capacity of points chosen.

NOTE: The rigging of loudspeaker systems is an extremely serious matter with potentially
lethal consequences should anything go wrong. It is of vital importance that you, or other people
rigging the system, are suitably qualified to do so and have a full understanding of all the factors
involved with safety as a number one priority. Turbosound accepts no responsibility for any
accident, damage or failure of any rigged system. This rigging information is specifically related to
the requirements of QLight™ enclosures only. For more detailed information on the whole topic of
rigging various handbooks are available. If you are in any doubt contact your Turbosound dealer
who will be able to refer you to an experienced rigging company.

Choosing the best location
When using any QLight™ system, certain room parameters will affect the resultant sound quality
and coverage. For example, any boundary like a wall or floor will lift certain frequencies. If you are
placing the unit in a corner then a lift at the bass end is to be expected and it may sound rather
boomy. This can be compensated for moving the speaker or cutting low frequencies with a
graphic equaliser.

graphic equaliser.
When speakers are flown in free space then boundary effects are minimised. The result is a
smooth frequency response without any boost at odd frequencies, but the bass end may appear
subjectively light. In this case increase the sub-bass level to bring the low end up.

The relationship between sound pressure level and distance is an “inverse square law” so
remember that every time the distance from the sound source is doubled the sound level
decreases by 6dB. For every 3dB increase in SPL you need a doubling of input power and you can
work out the wattage input needed to give the required SPL levels at various distances from the
loudspeaker(s).
