2.4.2 Cautions

CAUTION:

Do not bundle any lines from this unit

with transmitter coax feedli

nes. Do not

bundle any logic, audio, or DC power lines from this unit with 400 Hz synchro

wiring or AC power lines. Do not position this unit next to any device with a

strong alter

nating magnetic field such as an inverter, motor or blower, or

significant

audio interference will result.

In all installations, use shielded cable exactly as shown, and ground only as

indicated. Significant problems may result from not following these guidelines.

2.4.3 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 connector map 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. Reference 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 from the panel for easy access to all side adjustments. Do NOT mount the

unit until all adjustments have been performed.

Maintain wire segregation and route wiring in accordance with the original aircraft manufacturers

Maintenance Instructions.

Unless otherwise noted, all wiring shall be a minimum of 22 AWG, except power and ground lines, which

shall be a minimum of 20 AWG. Refer to the Interconnect drawing for additional specifications. Check that

the ground connection is clean and well secured, and that it shares no path with any electrically noisy

aircraft accessories such as blowers, turn and bank instruments or similar loads. Power to this unit must

be supplied from a separate circuit breaker or fuse (fast blow), and not attached to any other circuit

breaker without additional protection. Verify that the selected circuit breaker size and wire gauge are

adequate for the installation using the techniques specified in AC43.13-1B Change 1, Paragraphs 11-47

through 11-51 and 11-66 through 11-69.

2.4.4 Post Installation Checks

2.4.4.1 Voltage/Resistance Checks

Do not attach the AA35-001 until the following conditions are met.

Check the following:

a) J1 pins <1> and <2> for +28 Vdc relative to ground.

b) J1 pins <20> and <21> for continuity to ground (below 0.5).

These commodities, technology or software are controlled in accordance with the United States Export Administration Regulations, Export Classification

Control Number(ECCN) EAR99. When exporting, diversion contrary to U.S. law is prohibited.

2.4.4.2 Power On Checks

Power up the aircraft’s systems and confirm normal operation of all functions of the AA35-001. Refer to

Section 3.0 (Operation) for specific operational details.

a) Check for the correct audio output on each channel.

Upon satisfactory completion of all performance checks, make all required log book entries, electrical

load, weight and balance amendments and other documentation as required by your local regulatory

agency before releasing the aircraft for service.

2.5 Adjustments and Connections

WARNING:

These procedures should be performed by a qualified service

technician, at an ESD safe workstation only. Failure to adhere to this

warning could cause injury to personnel and/or damage to equipment.

2.5.1 8/600 



Adjustment

Remove the cover from the AA35 and locate the seven 8/600  adjustment jumpers (JP1 thru JP7).

Each jumper controls one of the six independent channels or the Composite Output (refer to table 1).

When the jumper is connected across pins A and B, the channel is set to operate with an 8  load

connected. When connected across B and C (the default setting), the channel is set to operate with a

600  load connected. Refer to the Maintenance Manual for complete details.

Table 1: 8/600  Jumpers

2.5.2 Input Audio Level Adjustment

The input audio level adjustment consists of six DIP switches (S1 thru S6), accessible from the right hand

side of the AA35. Each switch controls one of the six independent channels. The switch number reflects

the channel being controlled (e.g. S1 controls channel 1 and S4 controls channel 4). Each level can be

set to allow a 2.5 V (switch up) or a 7.5 V (switch down) input.

Section 3.0 Operation

3.1 Introduction

Information in this section consists of the functional and operational procedures for the AA35-001 Audio

Mixer Panel.

3.2 General Information

The AA35-001 Audio Mixer Panel is a six channel summing amplifier with independent level control for

each input. It can be used as an expansion panel for existing audio controllers.

The AA35-001 Audio Mixer Panel provides six independent channels with differential inputs and balanced

outputs for high common mode noise rejection. Also provided is a composite output. Each channel is

individually adjustable with a 40 dB range. The input audio level is internally selectable by DIP switch to

2.5 or 7 Vrms. Output impedance of each channel is individually selectable via internal jumpers to allow

the connection of an 8 or 600  load.

3.3 Controls and Indicators

3.3.1 Channel Controls

The AA35-001 has six front panel rotary controls. Each one controls the volume level of an independent

channel. With the control fully counterclockwise it is in the OFF detent position and no audio will be heard

on the headset for that channel. Rotating the control clockwise past the detent will turn the channel on.

The volume will increase as the control is rotated clockwise and decrease as it is rotated

counterclockwise.

WARNING:

High volume settings can cause hearing damage.

Set the headset volume control to the minimum volume setting, and

slowly increase the headset volume to a comfortable listening level.
