CAUTION:
Do not operate the equipment in a hangar or in confined areas.
Do not operate the equipment with snow, water or other foreign matter in the
loud speaker horn.
Do not clean the loud speaker with compressed air.
Bundle and route the Speaker Output wires separately from low level Audio

Always check ADF and compass calibration after installing external speakers
or power amplifiers.
2.3.3 Cabling and Wiring
All wire shall be selected in accordance with the original aircraft manufacturer's Maintenance Instructions
or AC43.13-1B Change 1, Paragraphs 11-76 through 11-78. Unshielded wire types shall qualify to MIL-
W-22759 as specified in AC43.13-1B Change 1, Paragraphs 11-85, 11-86, and listed in Table 11-11. For
shielded wire applications, use Tefzel MIL-C-27500 shielded wire with solder sleeves (for shield
terminations) to make the most compact and easily terminated interconnect. Follow the interconnect
drawing in Section 2.7 as required.
Allow 3" from the end of the shielded wiring to the shield termination to allow the connector hood to be
easily installed. Refer to the interconnect drawing in Section 2.7 for shield termination details. Note that
the hood is a "clamshell" hood, and is installed after the wiring is complete. Aircraft harnessing shall
permit the unit to be removed for easy access to all adjustments.
Maintain wire segregation and route wiring in accordance with the original aircraft manufacturers
Maintenance Instructions.
2.3.4 Mechanical Installation
The installing agency is responsible for the design, engineering and installation of the mounting bracket
for the LSxxx Series High Power Loud Speakers. Careful consideration should be given to the operating
environment and the mechanical forces acting upon the LSxxx Series unit(s).
The guidelines used in the AC43.13-1B Advisory Circular should be used to provide general reference to
the selection of hardware, torque values, etc. The specific references are contained in AC43.13-1B,
Chapter 7, Table 7-1.
A minimum of five mounting 1/4“-28 bolts per side is recommended for the LS300-200 and LS600-200
speakers. The bolts should have a torque value of 50 –70 inch lbs as per the AC43.13-1B. Refer to the
following diagram for the mounting hole pattern.
