Prior to Installation
3.1.1 During the design and layout of the aircraft cabin, careful
consideration of the location of this and all other audio/visual
modules is necessary. Some of the items to be considered include:
•
Space
•
Proximity to other devices (i.e. source equipment)
•
Available power supply
•
Length of cable runs
•
Environmental conditions (temperature, humidity, etc.)
•
Location of other aircraft systems (i.e. oxygen delivery)
•
Access for service repair (if applicable)
•
Convenience for user interface (if applicable)
3.1.2 The MCD-9101-101-x 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. Long low-level
audio runs may introduce noise into the audio signal.
3.1.4 All headphone amplifiers and line level amplifiers should be located
no more than 3 feet away from source equipment.
3.1.5 Avoid installing the unit where it will be exposed to excessive heat,
moisture, splashing liquids, dusty areas, direct sunlight, or
angled/inclined installation.
3.1.6 A minimum of 5" clearance is required in front of the CD slot. When
the CD is ejected, it will project approximately 2.25".
3.1.7 The installing agency shall supply and fabricate all external cables
to the MCD-9101-101-x. The length and routing of external cables
shall be carefully studied and planned before attempting installation
of the unit. Allow adequate space for installation of cable and
connectors. Mating connectors are the responsibility of the
installing agency. Correct pin assignments as outlined in Section
3.8 are the responsibility of the installing agency
.
