1.1. This document provides general information and instructions for the
installation of the Geneva P139-HD Digital Audio System, under STC
SR00521SE.
1.2. Installation is to be accomplished in accordance with Geneva Aviation
instructions. Throughout the installation of this product it is necessary to
utilize proper aviation practices. Be sure that the installation of this product
is in compliance with the aircraft manufacturer’s limitations and also that it
is done in accordance FAA publication, AC 43.13-1B, Acceptable Methods,
Techniques and Practices, Aircraft Inspection and Repair. These rules
from the AC apply :
A. All wire to be 22 AWG unless otherwise specified.
B. Unshielded wire per MIL-W-22759/16; Shielded wire per MIL-
M27500-xxTGxT14 ; xx- indicates wire gauge, x- indicates
number of conductors.
C. Route and support wiring harness IAW AC 43.13-1b, Chapter

E. Clamp and route wiring harness around movable controls IAW
AC 43.13-1b, Chapter 11, Section 9, Paragraph 11-125.
F. Wiring and harness to be separated IAW AC 43.13-1b,
Chapter 11, Section 8, Paragraph a 11-105 & 11-106.
G. Install service loops at harness terminations IAW AC 43.13-1b,

Before installing any of the components, first read through all of the
documentation to become familiar with the installation requirements. This
installation requires a completed FAA Form 337 and appropriate log book
entries.
Prior to installing each component, record weight and mounting location in the
aircraft’s weight and balance record.
This product is provided with an FAA STC for certain aircraft models. If your
installation is not covered by one of the models listed on the STC, then you may
need to obtain a field approval from your local FAA Flight Standards District
Office (FSDO).

The P139-HD Digital Audio Router contains no user serviceable internal
components. Do not disassemble router or the factory warranty will be voided.
For service, return the unit to Geneva Aviation.
1.3. There are three types of P139-HD Audio Systems that the installer may
choose to install at their discretion.
1.3.1. P139-HD (D) Uses Router G13000 in a “Dual-board” configuration
and is shown in the diagrams and is the router used throughout the
instructions.
1.3.2. P139-HD (S) Uses Router G13000 in a “Single-board” configuration
that uses the same case as the dual-board router, but with only one
audio board installed. These two routers share the same installation
and wiring drawings.
1.3.3. P139-HD (T) uses Router G13160 and is a “Three board”router.
This installation replaces wiring drawing G13004 with drawing
G13162. Installation of this router is performed the in the same
manner as the other two routers with slight changes in the mounting
hardware as noted in the instructions.
1.4. Prior to installation of this system, it is the responsibility of the installer to
confirm by analysis, that the additional power requirement will not exceed
the capacity of the Essential Buses or the aircraft’s electrical system.
Power consumption for this audio system is 5 amps maximum at 28 volts.
The system is designed to use redundant power sources, from 28 VDC
Essential Bus #1, and from 28 VDC Essential Bus #2. For each supply
line, use a separate 5 amp circuit breaker and separate ground lines to two
separate ground points. Refer to G13004 for wire harness details. The
system will support supply voltages of 14 –32 VDC.
1.5. The internal power supply of the router is sufficient to power six audio
control panels. If the installation calls for more than six panels, the
additional panels must be powered from a separate circuit breaker to the
Router. Refer to G13004 sheet 12 for more information.
1.6. The FAA requirement regarding the securing of wire bundles using
nonmetallic clamps is addressed by the use of nylon cable ties. The part
numbers and description of these ties is as follows:
Following the guidelines in AC43.13-1B, cable ties are attached at a
maximum of 4” spacing and ties are attached to nylon cable tie anchors, as
necessary.

1.7. The aircraft into which this product will be installed may be a new aircraft or
an aircraft that has been in service. The configuration of the wiring and
cabling will vary from aircraft to aircraft. The installation of the Geneva
Aviation Audio System should use existing wire and cable runs when
possible as it will not interfere with the existing aircraft wiring.
1.8. These instructions call out cables by reference to the drawing that defines
the cable construction details. The installer may, at the installer’s
discretion, substitute connectors, wire type, and connection details, so long
as the final installations operate correctly and meets FAA standards.
1.9. The Router features a COM1 Isolate mode that automatically connects the
pilot’s headset and mic switches directly to COM1 in the event of power
loss or failure of the Audio Router. The pilot may also activate the COM1
Direct mode using the EMERG/NORMAL switch on the G13115 and
G13116 control panels. This feature may also be set up for the Copilot to
activate a COM2 Isolate mode using the EMERG/NORMAL switch on the
copilot control panel.
1.10. For Non-Pilot positions, Control Panels G13115NS or G13116NS may be
used. The panels do not have an internal COM1, COM2 isolate switch.
For these panels, do not connect to the COM1 or COM2 circuits shown in
wiring diagrams G13004.
