Installation
3.1
During the design and layout of the aircraft cabin, careful consideration of
the location of this module is necessary. Some of the items to be
considered include:
•
Space
•
Available power supply
•
Environmental conditions (temperature, humidity, etc.)
•
Length of cable runs
•
Proximity to other devices (i.e. source equipment)
•
Convenience for user interface (if applicable)
•
Access for service repair (if applicable)
•
Location of other aircraft systems (i.e. oxygen delivery)
3.1.1 The AI-ST100X shall be installed to conform to the standards
designated by the customer, installing agency, and existing
conditions as to the unit location and type of installation.
3.1.2 Mounting screws are required to secure the unit. Refer to
Section 6.0, Reference Drawings, for mounting hole diameters and
configuration.
3.1.3 The unit must be located as close to source equipment as possible.
Long low-level runs may introduce noise into the audio signal.
3.1.4 Locate the unit to allow ease in adjustments. Master gain
potentiometers are located on the rear of the unit and must be
accessible for system adjustments and periodic maintenance.
