1.2.5 Masonry walls. Surface duct shall be accepted only where AV cables cannot be run in wall cavities

or embedded trunking. Cable runs shall be located such that they blend in with existing fixtures,

following shadow lines, room corners, whiteboard edges, etc where possible. Unless otherwise

noted, vertical surface duct shall run the full height from floor to ceiling.

1.2.6 Glass walls. No AV cabling shall be run down or across glass walls. Where there are no masonry

or cavity walls which can be utilised for vertical cable runs, it may be possible to run suitably sized,

surface duct on the glass framework. Such surface duct may need to be a non-standard colour, or

may need to be paint colour-matched after the duct has been installed. It is mandatory, in all such

instances, that direct instructions in writing be obtained from Swinburne ITS AV before any work

commences.1.2.7 Grid ceilings. All cable runs in grid ceiling spaces that exceed 3m in length shall be secured off the

ceiling surface using tensioned catenary wire, so that the AV cables maintain separation from the

ceiling surface of 100mm minimum and separation from other ceiling plant equipment of 300mm

minimum. The cables shall be attached to the catenary wire using Velcro straps spaced no further

than 1m apart.

1.2.8 Solid plaster ceilings. All cable runs in solid plaster ceiling spaces shall be secured off the ceiling

surface using Panduit J hooks, spaced at an interval no greater than 1.5m.

1.2.9 Slab coring. Where AV equipment resides in an island bench requiring AV cables to pass from the

bench to wall/ceiling, the AV cables shall pass between the two in a safe and unobtrusive manner.

Subject to approval from Swinburne Facilities & Services Group, the slab beneath the island bench

and a suitable location next to the wall shall be cored to allow AV cables to pass from the bench to

the wall under the slab. Cables under the slab shall be carried in solid PVC pipe with a minimum

internal diameter of 75mm. Elbow joins are to have a minimum internal radius of curvature of 50mm

2. System Requirements

2.1 General Layout and Design Principles

2.1.1 Non-standard equipment. The physical characteristics, walls, doors, windows, air conditioning, room

size, etc., of general classrooms and other teaching spaces, can vary greatly, and are often beyond

the control of Swinburne ITS AV. These characteristics can impact AV installations, placing unique

conditions on both equipment type and appropriate layout suited to each teaching spaces.Swinburne ITS AV will advise in writing where non-standard equipment is to be used in such

instances. Unless expressly noted, it is accepted that the standard design and equipment are

suitable for the teaching space.

2.1.2 Direction and orientation references. When using terms to describe left and right, such terms must

always be from the audience viewing/listening point.

2.1.3 Numerical reference of screens and data projectors. When describing screens/data

projectors/microphones using numerical reference #1 is always the left item and #2 is always the

right item, as per left/right conventions noted in item 2.1.2. Where there is equipment in addition to a

standard installation, additional arbitrary numbering is permitted, starting at #3 and increasing.

2.1.4 Proximity to building services. Equipment shall be installed in locations such that the equipment

does not obstruct full use of access hatches, service cupboards and doors, air conditioning filters,

cable duct covers etc. A minimum clearance of 300mm is required between any AV equipment and

fire sensors or evacuation speakers.

2.2 Classroom Teaching Space Layout and Design Principles

2.2.1 Data Projector Screen location. The screen must be located on the presentation wall, offset away

from any large sources of natural light. The offset must allow for simultaneous use of any main

whiteboard. Where the screen has a manual chain-drive, the chain-drive must be located on the

side of the screen which is furthest from the centre of the whiteboard, to allow maximum use of the

whiteboard while the screen is retracted.

desk must be positioned such that the presenter has practical use of any main whiteboards, and not

directly in front of the data projector screen.

2.2.8 General AV equipment location. Unless specified in writing from Swinburne ITS AV, equipment is to

be located in an approved secure rack, mounted underneath the presenters desk, adjacent to the

presentation wall. The rack shall be secured such that it prevents general access to data points, AV-

reserved GPOs, and AV-related cabling.

2.2.9 Keypad location. The keypad is to be located to the presenter desk side of the data projector

screen. It must be located such that it is visible to the presenter when the screen is down.2.2.10 Ambient light. Where external light can cause reflections on whiteboard surfaces or saturate the

presentation wall, the room must be fitted with appropriate window coverings, blinds/curtains, which

provide at least 70% blocking of ambient light.

2.3 Theatre Layout and Design Principles

2.3.1 Data projector quantity. All theatres must have a minimum of two data projectors configured in a

side-by-side manner. Each projector must be controlled individually from a central control location

and be able to show (in a mix-n-match style) any of the standard sources available to the presenter.

The gap between each display area from each data projector must be no greater than 500mm.

2.3.2 Data projector matching. The two data projectors must be of the same make/model with the same

lumen output, mounted at the same throw distance. Any additional data projectors are permitted to

be a specialist make/model, subject to written approval from Swinburne ITS AV.

2.3.3 Data projectors screens. Subject to venue requirements, the venue may be fitted with motorized

screens for data projector use. Where such screens cover the main whiteboard, a screen override

button must be fitted to allow retraction of the screen. The override button must be mounted

immediately below the whiteboard pen tray or bottom of motorized screen in the down position,

which ever is the lower of the two. The override button must be located horizontally central to the

screen which it is controlling.

2.3.4 Proximity to building services. Equipment shall be installed in locations such that it does not obstruct

full use of access hatches, service cupboards and doors, air conditioning filters, cable duct covers

etc.. A minimum clearance of 300mm is required between any AV equipment and fire sensors orevacuation speakers.

2.3.5 Presenters desk location. The presenters desk must be located at the front of the theatre, fixed to

the floor to prevent movement. The following minimum clearances must be observed to allow

servicing of equipment:

AFFL. There is to be no furniture below the whiteboard which may obstruct full use of the

whiteboard surface.

2.3.8 Lighting. Theatre lighting must be integrated with the theatre control system. The presenter must be

able to adjust lighting levels over the seating. The theatre AV control system must automatically

control lighting over the whiteboards, based on the data projector usage. Whiteboard illumination

must be separated into left and right halves, so that one half of the whiteboard can remain

illuminated while the other half is dimmed for data projector usage.

2.3.9 Touch Panel. The touch panel must be mounted securely on the presentation desk at an incline of

45o. The touch panel must be within 550mm reach of the presenters side of the desk.

within the seating area and the average of the three measurements combined to produce an aggregate

frequency response. The measuring locations for each venue are to be determined by Swinburne ITS AVand documented on a seating plan document to ensure tests can be repeated at a later date. Equalization

adjustments to the relevant DSP output(s) should be adjusted until the desired frequency response is

achieved. A transfer function of the acoustic response is measured using the following parameters: C-

weighting, 1 second average, 1/6 octave smoothing, 40% coherence threshold.

6.3.1 Program Audio frequency response

For frequencies between 90Hz and 9kHz, the amplitude deviation from the average should be no

greater than 3dB.

Frequency response outside the above range should roll off.

7. Lighting Requirements for Teaching Spaces

To ensure legibility of presentation content and sufficient illumination for note taking, the following is a outline to

general lighting requirements. Unless specified by Swinburne ITS AV, the following requirements are considered

acceptable for standard teaching spaces.

Ambient light is the level of light reflected off the centre of the projection screen, with the projector lamp turned off.

Projected light is the level of light reflected off the centre of the projection screen, with the projector lamp turned onand projecting a white 6500k image.

7.1 Classroom Lighting Levels

7.1.1 Presentation area

The ratio of projected:ambient light shall be a minimum of 10:1 at the projection screen.

7.1.2 Seating area

A minimum level of 150 lux over the seating area is acceptable when note-taking is required.

7.2 Lecture Theatre Lighting Levels

7.2.1 Presentation area

The ratio of projected:ambient light shall be a minimum of 20:1 at the projection screen.

7.2.2 Seating area

A minimum level of 150 lux over the seating area is acceptable when note-taking is required.

7.2.3 Camera recording

A minimum level of 300 lux at the presentation area is acceptable when camera-based automated

recording is taking place.

Lighting for camera-based recording shall be configured to minimise spill onto the presentation

screens. This shall be achieved primarily by suitable placement of luminaries, without blocking

audience sight-lines or disruption of projected images. Further beam-shaping may be required to

prevent spill onto the presentation screens.
