6. Crossovers
For optimal performance the B475 has been designed to operate with Tannoy Install
or Transportable series, e.g. i12/T12, i15 and T300, where overall system control is
achieved by utilising the TDX2 system controller. The TDX2 has been factory preset
to provide the recommended cross-over points, delays and overall system balance.
Please refer to the TDX2 manual for operation. Alternatively, Tannoy TX1, TX2 and
TX3 system controllers can be used.
If you intend using an alternative loudspeaker management system (e.g. BSS™, Klark
Teknik™, XTA™ etc) please contact your distributor or visit our website,
www.tannoy.com
for the correct parameter settings or refer to the recommended
crossover points in the technical specifications section of this manual.
7. Equalisation
The B475 loudspeaker is designed to need no equalisation or correction to overcome
system limitations. As a result, it will only need equalisation to compensate for difficult
acoustic environments.
Over equalisation can reduce system headroom, and introduce phase distortion
resulting in greater problems than cures. If equalisation is required then it should be
applied gently and smoothly. Violent equalisation will be detrimental to the overall
sound quality.
8. Flying
The B475 utilises convenient flying points as well as 2 MAN pullback points allowing
for ease of installation and flexibility with the highest levels of safety. As with any flying
system, safety can only be guaranteed when all precautions have been implemented
correctly. A pole mount is also provided for flying a mid/high cabinet in the air.
NOTE: The installation of this product must be carried out in conformity with
local building codes and standards. If necessary, consult your local safety
standards officer before installing any product. Alternatively, check any laws or
bylaws. Tannoy will not be held responsible for any damage caused by the
improper installation of any flying gear or loudspeaker.
