Installation and Operator’s Manual
1 SECTION I - GENERAL INFORMATION
1.1 INTRODUCTION
Ease of installation and simple operation make the AP 100 Audio Management System
the communication solution for a wide variety of aircraft panels, from the Homebuilt
through heavy twins. The AP 100 satisfies the need for convenience of a fully
functioning quality Audio panel that can be counted on to provide years of reliable
service.
Before installing and /or using your new AP 100 Audio Panel please read this manual
completely. This will ensure proper installation and familiarize you with all of the
features your new audio panel has to offer.
1.2 SCOPE
This manual will provide detailed information about the installation and operation of the
AP 100 Audio Panel. It will also provide equipment limitation information and
instructions for continued airworthiness.
1.3 EQUIPMENT DESCRIPTION
The AP 100 has been designed for simplicity. It is straight forward to install and operate.
Using state of the art technology Val Avionics has created an Audio Panel that will
provide the pilot with simple unencumbered control of the various audio sources
commonly found in today’s civil aircraft.
The COM 1 / COM 2 XMT SEL switches make it easy to select a transceiver for
transmitting and receiving radio communications. The selected transceiver is indicated by
an illuminated LED. This LED flashes while the transmit key is depressed. Received
audio from the selected transceiver is automatically switched to the headphones.
Received audio from both COM 1 and COM 2 can be routed to the headphones as desired
by activating the BOTH switch. When both audios are selected an LED annunciation will
illuminate.
NAV 1 and NAV 2 audios can be switched to the headphone using the NAV 1 and NAV
2 selector switching. These selections are also indicated by LED annunciation. All of the
selected audios can be switched to the cabin speaker with the SPKR select switch. An
LED annunciation will indicate this selection.

Muting for the external marker beacon receiver audio is provided by the MKR switch. A
steady LED annunciator for the MKR switch indicates that marker beacon received
audio, if present, will be heard in the headphones and over the cabin speaker if the SPKR
switch is selected. The pilot may mute the marker audio by depressing the MKR select
switch. Doing so will mute the incoming marker audio for approximately 20 seconds.
While the marker audio is muted the MKR LED annunciator will flash.
Four un-switched audio inputs are provided at the rear connector for such audio inputs as
DME, ADF, Auto Pilot alerts or any other audio source which would commonly be
routed to the aircraft headphone and cabin speaker systems.
A Fail-safe feature has been incorporated into the design of the AP 100 that will
automatically connect the pilot’s headphones and microphone to the aircrafts COM 1
radio in the event that power is removed from the audio Panel or if the unit is powered
down.

2 SECTION II - INSTALLATION
2.1 GENERAL INFORMATION
2.1.1 Scope
This section of the manual will provide the needed information to successfully complete
the installation of your new AP 100 Audio Panel. Please read this section completely
before proceeding with the installation process. Although the AP 100 installation
procedures are designed with the do-it-yourselfer in mind, we at Val Avionics strongly
suggest that you seek the advice of a qualified avionics installation facility before
beginning this or any other installation project. Qualified Avionics installation
technicians can offer good advice as to time-tested installation practices and techniques
that can save you many hours of time and frustration.
2.2 UNPACKING AND INSPECTION
Use care when unpacking the equipment. Inspect the unit and supplied parts for visual
signs of damage during shipment. Examine the unit for loose screws, dents, broken
buttons and other signs of damage that may have occurred during shipment. Verify the
contents of the container with the list in section 1.5. If any damaged or missing parts are
discovered during the inspection save the shipping material and contact the freight carrier
to file a claim. If it is suspected that parts were omitted from the container please feel free
to contact Val Avionics to acquire the missing items.
2.3 EQUIPMENT INSTALLATION PROCEDURES
2.3.1 Cooling Requirements
Forced air cooling is not required for the AP 100 audio Panel. However, when planning
the location for mounting ensure adequate spacing from heat producing sources such as
heating or defrosting ducts.

2.3.2 Mounting Requirements
The AP 100 Mounting Tray (VPN 0511002) should be rigidly mounted in the avionics
stack using the hardware provided in the installation kit. Ensure that the mounting
location will provide easy access and a clear view of the equipment’s front panel from the
pilot’s position. Ensure that the mounting position will provide adequate clearance
between the unit and the associated wire harness and the aircraft controls. Bracing at the
rear of the unit should be installed to ensure rigidity in the panel. Consult FAA Advisory
Circular AC 43.13-2A for acceptable practices and techniques.
2.3.3 Wire Harness Fabrication
Val Avionics recommends that a factory fabricated wire harness (VPN 0751005) be used
for the installation of the AP 100 Audio Panel. Use of the factory fabricated wire harness
will ensure proper operation of the Audio Panel, reduction in the occurrence of
interfering audio signals and ground loops, greatly reduced installation time, and provide
prolonged trouble-free performance of your new equipment. Contact Val Avionics or
your local avionics distribution center for AP 100 Wire Harness ordering information.
Although strongly recommended, it is not required to use the factory fabricated wire
harness when installing the AP 100 Audio Panel. A wiring harness can be fabricated in
the field. Refer to appendix B of this manual for a complete wiring diagram. All wires
must be 22 AWG MIL-SPEC, unless otherwise noted in accordance with current
regulations. Two and three conductor shielded MIL-C-27500 or equivalent wire must be
used where indicated. Use AMP Contact Crimping Tool (AMP P/N 601966-1) with
Positioning Tool (AMP P/N 601699-5) or equivalent to ensure good quality contacts.
Refer to FAA Advisory Circular AC 43.13-2A for acceptable practices and techniques.
2.3.4 Audio Panel Installation
Carefully insert the Audio Panel into the mounting tray. The unit should slide into the
tray freely without binding. Approximately 3/8” before complete insertion into the tray
check for alignment of the DB25 connector on the unit and the mating DB25 connector at
the back of the tray. Using a 7/64” allen wrench access the locking pawl screw located at
the top center access hole on the face of the unit. Rotate the screw clockwise to draw the
Audio Panel fully into the mounting tray. There will be a .020” gap between the back
surface of the unit’s faceplate and the front edge of the mounting tray when the unit is
fully seated.
