3.0 Installation
3.1 Prior to Installation
The EN-6xxW-xx Series speakers are simple modules to install. 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 and all other audio/video
modules is necessary. Some of the items to consider include:
• Space
• Proximity to other devices (i.e. source equipment)
• 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 EN-6xxW-xx Series speakers 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.
3.2 Unpacking and Inspection
3.2.1 Carefully open the packaging and remove the speaker. 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 Audio International WITHIN 24 hours and a Return Request
Authorization Number shall be obtained from AI. Refer to the
front cover of this manual for address and telephone number of
Audio International, Inc. Repackage the unit in its original
packaging materials and return it to AI following instructions given
by the AI representative. If no return is necessary, retain the
packing list and the packing materials for storage.
3.3 Cautions and Warnings
3.3.1 It is important to do a pin-to-pin power and ground check on all
connectors. Ensure that Audio Input + and Audio Input - 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 remove any factory-installed screws. Damage to the
unit(s) may result and void any warranties.

Audio International, Inc.EN-6xxW-xx Series Installation Manual
3.3.3 DO NOT install near heat sources such as direct sunlight, warm air
exhausts, or heaters.
3.3.4 No scheduled maintenance is required to ensure continued
airworthiness.
3.3.5 ESD (Electro Static Discharge) guidelines shall be followed.
3.4 Wiring Requirements
3.4.1 The installing agency shall supply and fabricate all external cables
and connectors. Length and routing of external cables should be
carefully planned before attempting installation of the equipment.
Allow adequate space for installation of cable and connectors.
3.4.2 Ensure that all signal wires are 18 AWG minimum (16 AWG
recommended).
3.5 Physical Characteristics
3.5.1 The speaker shall be located away from heat sources, magnetic
fields, direct sunlight, and areas with excessive dust. The unit shall
NOT be mounted to the skin of the aircraft.
3.5.2 Refer to 6.0 for unit dimensions and mounting hole sizes.
3.5.3 The unit shall be rigidly mounted to its location using the
appropriate fastening hardware supplied by the installing agency.
3.5.4 When mounting the unit to the aircraft’s frame, allow sufficient
space for mating connectors.
3.5.5 Do not remove the speaker from the enclosure; the speaker is
sealed in place to provide optimum performance.
3.5.6 Audio International recommends not restricting airflow in front of the
enclosure. Coverings or grills not specifically designed for
loudspeaker performance may cause unacceptable loss of sound
quality.

4.0 Troubleshooting
4.1 Introduction
Most functional problems will be detected during the post installation test;
refer to Post-Installation Test, Section 3.9. Once the unit has passed
these tests, it can be functional for many years of service. Most problems
with sound quality are not due to subwoofer performance, but instead are
caused by source equipment or faulty audio material. Always check
source equipment and audio material as well as the speaker in question.
NO scheduled maintenance is required to ensure continued airworthiness.
EN-6xxW-xx has no customer-serviceable parts. If the unit does not work
properly, it should be removed and replaced. Contact Audio International
for details.
4.2 General Troubleshooting Procedures
• Recheck all connections to the unit for security. Check all harness
runs for possible pinching and all pinouts for application accuracy.
The following troubleshooting procedures apply to the equipment
supplying audio to the subwoofers and not to the subwoofers
themselves.
• Reset by removing power from the unit for at least one (1) minute and
reapply power.
• To verify power to the unit, recheck +28 VDC power is applied to the
proper pins on the unit. Use a voltmeter to verify correct level.
• To check data bus integrity, utilizing a voltmeter, oscilloscope, or other
voltage instrument, verify proper input voltage on the data bus pins.
Typical measurements with no device(s) on bus transmitting are as
follows:
A-to-Ground : 4.0 to 4.5 VDC
B-to-Ground : 0.1 to 1.0 VDC
If any device is transmitting (i.e., holding bus active), then these typical
measurements would be reversed for the A-to-Ground and B-to-
Ground measurements. This troubleshooting tool can help indicate a
data bus lockup. If this occurs, remove the data bus from all other
equipment one piece at a time. As each is removed, check the bus
status to see if it is now functioning properly. Once you have removed
the piece or pieces of offending equipment, disconnect power and then
reconnect everything but the suspect component, reapply power and
test the functionality of the unit.

Audio International, Inc.EN-6xxW-xx Series Installation Manual
• The RS-485 data bus is a bi-directional bus that does not have a ‘bus
controller’. The bus uses a differential digital signal that will transmit
only when commands are entered via switch selection or other system
synchronizing commands. The “A” leg of the bus is HI and the “B” leg
LOW.
