1.4 Optional Equipment

1.4.1 The MCD-9101-101-x can be optionally controlled by infrared

remote or DeCrane Aerospace Audio International’s touch screen

panel. Digital codes allow the unit to interface with an infrared

handheld remote via an infrared receiver. Multiple units can be

controlled independently using available programming pins.

1.4.2 The removable front cover bezel may be customized to match the

interior style of any aircraft. This option includes plating or painting

to match aircraft décor. Each MCD-9101-101-x unit may be fitted

with bracket assemblies allowing the unit to be mounted in the

same space as any existing Audio International CD model. The

cover bezel is not an integral part of the CD and must be ordered

as a separate item (P/N 13901720). Contact your DeCrane

Aerospace Audio International representative for details.

1.4.3 DeCrane Aerospace Audio International also offers a wide variety

of monitors, speakers, headphone jacks, video distribution devices,

and other equipment that will perfectly complement the

MCD-9101-101-x.

2.0 Application

2.1 Introduction

The MCD-9101-101-x is an Air Jukebox that will accept a +5 VDC infrared

digital input and DeCrane Aerospace Audio International’s proprietary

RS-485 two-wire serial data bus input.

MCD-9101-101-x is compatible with standard commercial audio CD. Note

that since compact disc format standards are constantly evolving, some

discs may not play properly or may cause the unit to malfunction.

DeCrane Aerospace Audio International does not guarantee the

MCD-9101-101-x is compatible with all media or formats.

The MCD-9101-101-x can be mounted in a cabinet or bulkhead. A unique

ID address pin feature allows multiple devices to be used in the same

system at the same time while maintaining independent control.

3.0 Installation

3.1 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.

3.2 Unpacking and Inspection

3.2.1 Carefully open the packaging and remove the MCD-9101-101-x.

Verify that all components have been included in the package per

the packing list. Inspect the unit for shipping damage.

3.2.2 If damage has occurred during shipping, a claim should be filed

with DeCrane Aerospace Audio International WITHIN 24 hours and

a Return Request Authorization Number shall be obtained from

DeCrane Aerospace Audio International by contacting the Repair

Department at 501.801.8101. Repackage the unit in its original

packaging materials and return it to DeCrane Aerospace Audio

International following instructions given by the DeCrane

Aerospace Audio International representative. Refer to the front

cover of this manual for address. If no return is necessary, retain

the packing list and the packing materials for storage.

3.3 Cautions & Warnings

3.3.1 It is important to do a pin-to-pin power and ground check on all

connectors. Ensure that power and ground are applied only where

specified. Damage to the unit may result if power or ground is

applied to the wrong points.

3.3.2 DO NOT connect or disconnect the unit while power is applied.

3.3.3 DO NOT remove any factory-installed screws. Damage to the unit

may result and void any warranties.

3.3.4 DO NOT drop the unit or subject it to strong shock. The unit

contains glass parts that may break or crack.

3.3.5 DO NOT use commercially available CD accessories that can be

loaded into the CD slot (stabilizers, protective sheets, CD cleaning

discs, etc.). They can cause the unit to malfunction.

3.3.6 DO NOT use dirty CDs or CDs colored on the data side. If you try

to play CDs that are colored on the recorded side (opposite the

label), or CDs that are dirty, they may fail to slide in or out. Also, do

not put tape on CDs and attempt to insert into the unit. This could

cause failure or damage to the unit.

3.3.7 ESD (Electro Static Discharge) guidelines shall be followed.

3.3.8 No scheduled maintenance is required to ensure continued

airworthiness.

3.4 Wiring Requirements

3.4.1 Introduction

The installing agency shall supply and fabricate all external cables.

The length and routing of external cables shall be carefully studied

and planned before attempting installation of the equipment. Allow

adequate space for installation of cable and connectors. Avoid

sharp bends and placing cables near aircraft control cables.

Maintain a minimum clearance of 3" from any control cable. If wiring

is run parallel to combustible fluid or oxygen lines, maintain a

separation of 6" between the lines.

3.4.2 Power Wires

The chassis shall be electrically bonded to the airframe structure by

a conductive mounting point with <0.1 resistance using <50 

impedance cable. Aluminum wool, nylon webbing impregnated with

aluminum oxide abrasive or fiber bristle brushes are the approved

tools for removing anodized surfaces at mounting point where the

bonding wire is attached. Power and Ground wires shall be in

accordance with M227589 or equivalent.

3.4.3 Serial Digital Audio Wiring

All serial digital audio wire connections must be twisted shielded

cable with the shield properly grounded to the dedicated pin at the

source end to the dedicated pin at the load end. Twisted shielded

cable shall be 22 AWG (minimum) for digital audio signals and shall

be in accordance with NEMA WC 27500. Cable impedance must

be 110 +/- 10%.
