Pre-Installation Requirements
Console Control Surface
The AWS 900+ console is a self contained system; there are no remote power supplies or I/O racks.The frame
is not fitted with cooling fans.See the following page for a drawing of the console footprint.
Air Conditioning Requirements
It is unlikely that additional air conditioning will be required after installing the AWS 900+ (with its typical 450W
dissipation).It is possible however, that when all the studio equipment is taken into consideration, particularly if
additional lighting is being installed, the combined heat output could be sufficient to cause the temperature to
rise to uncomfortable levels.The appendix section contains environmental specifications for SSL equipment.
Cable Ducting
Cable ducting may be required between the console and any outboard racks and the recording areas.If a full
remote patchbay is being provided then the ducting will need to be of sufficient size to allow at least twelve 24-
circuit multicore cables to be accommodated.
Service Access
Access to all electronic assemblies within the frame is from the front of the console.Note however, that each of
the console’s modules is retained by a screw through its rear panel.Is necessary therefore, to have access to
the rear of the console.
Power Connections
The console is fitted with auto-sensing power supplies which will function at any voltage from 90 to 250 volts
without adjustment.It is supplied with two IEC mains power-leads.One will have a US-style 3-pin mains plug
fitted, the other will be unterminated to allow the user to install a mains plug of their preferred type; the wires
are colour-coded according to the EC standard.
Grounding
A standard system should not require any additional grounding over and above that provided by a correctly
installed mains supply.The console’s chassis is permanently bonded to mains earth.
Safety Warning: The mains input ground wire MUST be connected to the supply earth.
Thermal Considerations
The maximum dissipation of an AWS 900+ is less than 600W (typically 450W).The console is cooled by
convection from the front inlet (in the knee panels) to the exit at the top of the rear panels.It is very important
that these ventilation grills are not obstructed in any way.
Particular care must be taken when considering the installation of studio furniture – such as shelving – across
the rear of the console.Sufficient space
must be left for the free flow of air from the rear grills, and also above
the heatsink fins.Clearance behind the console must not be less than 50mm and clearance above the console
not less than 200mm.
Note: The heatsink fins on the console rear panels can reach temperatures of approximately 30
degrees Celsius above ambient room temperature.
