3.6 Installation
The Audio Visual Integrator is to install all equipment for the Audio Visual system as outlined
throughout this scope of works/specification and, if specified, University provided system block line
diagram. All works are to be completed to a high standard with a fully functioning Audio Visual
system handed over at completion of the project.
 Audio is to be free of any buzz, hum and any other undesired noise. Exact speaker positions
are to be based on a practical determination of what will give the best sound coverage from
the FOH (key decision factors being careful consideration of room layout, possible sound
obstructions, and dispersion properties of speakers).
 Video/Data projection is to be free of any hum bars, shimmer, flicker, ghosting, sparklies,
macro-blocking, drop-out, or any other undesired artefacts, up to the native input resolution
of the projection device.
 The projector alignment to the screen must be of the highest quality, without any optical or
digital image distortion. The projector lens must be aligned dead-centre to the vertical
centre line of the projection surface, and the projector must be mounted between 15-50%
below the top of the screen. The projector must be aligned straight and true to the screen
surface, it must not pan or tilt in order to project onto the screen surface. Every effort must
be made by the integrator to ensure perfect optical alignment of the projector to the screen.
Use of lens shift and/or image warping must only be used with the express written approval
of ISTS. Any misalignments must be resolved before a space is considered acceptable by the
University.
 Installed plates, controller, screen, duct or conduit, speaker brackets, projector bracket and
wall equipment cupboard are all to be installed square, flush and level. The mounting
screws/washers/bolts used to fix a specific item are all to be matching for that specific item
type.
 Audio Visual Integrator provided ceiling cut-outs for a projector ceiling mount pole are to be
neatly cut-out with a diameter no greater than 15 mm of that of the pole itself.
 Equipment racks – refer 2.1
 The Audio Visual Integrator is to dispose of any rubbish or refuse that is left over from
installations in an environmentally sustainable way. Any materials that are recycled require
the disposal process to be certified to a standard defined by ISTS.
 If required by the design specifications, the Audio Visual Integrator, in consultation with
ISTS, is to provide adequate power to the projector, lectern and any motorised projection
screen. Any installation of power requires the consultation of FMU, to ensure that all
necessary processes are followed. Typically a ceiling mounted double GPO is to be provided
at the projector with a double GPO provided to the cabled end of the projection screen
(ideally within ceiling cavity where possible) and two double GPO’s to the lectern. All circuits
for all AV equipment shall be linked to a common earth. All electrical works are to be
provided by a licensed electrician and completed to AS/NZS 3000:2000 and any other
relevant Australian Standards. Final number of power outlets to be determined during the
design consultation process.
All projector power switches must have an additional switch located within a secure space,
such as the lectern or a communications room, to allow the projector to be power cycled
without the need for a ladder or scaffolding.
