3.0 Installation
3.1 Prior to Installation
Prior to installation, the following items should be considered:
3.1.1 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
3.1.2 The PA-475-A (-B) (-C) 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.
3.1.3 Mounting screws are required to secure the unit. Refer to Section
6.0, Reference Drawings, for mounting hole diameters and
configuration.
3.1.4 The purpose of the audio amplifier is to compensate for low level
audio signals and “amplify”them to a high level. The amplifier will
be most effective when the interior is thoroughly furnished and all
pieces of furniture are in place.
3.1.5 The unit generates minimal heat. Allow a minimum of ½inch air
space around the amplifier due to heat generation.
