AA30-301 Expansion Panel Manual |
Section 1 Description
1.1Introduction
This manual contains information on the AA30-301 Expansion Panel. All derivative products will be covered by manual supplements, which can be obtained from NAT as required.
Information in this section consists of purpose of equipment, features and specifications.
1.2Purpose of Equipment
The AA30-301 is a Dzus-mounted 4-transceiver radio receiver expansion panel, designed to work in conjunction with the 380-series Audio Selector Panels.
1.3Features
The AA30-301 provides four ganged transmitter selector pushbutton switches and four receiver level panel potentiometers, each with an integral push-in / push-out selector switch, and utilizes the subassembly from a 247 Audio Mixing Amplifier for signal mixing, amplification and processing.
The AA30-301 is designed to be used in conjunction with a 380 panel to expand a single 380-series transmit microphone output into 4 outputs, and to expand a single
380-series receive audio input into 4 inputs.
The AA30-301 permits the audio system to support more receivers/transceivers than a single 380-series panel is capable of individually.

Section 2 Installation
2.1Introduction
Information in this section consists of: unpacking and inspection procedures, installation procedures, post-installation checks, and installation drawings.
2.2Unpacking and Inspection
Unpack the equipment carefully and locate the warranty card. Inspect the unit visually for damage due to shipping and report all such claims immediately to the carrier involved. Note that each unit should have the following:
-AA30-301 Expansion Panel
-Warranty Card
-Operator’s Manual
-Release certification
Verify that all items are present before proceeding and report any shortage immediately to your supplier.
2.2.1Warranty
Complete the warranty card information and send it to NAT when the installation is complete. If you fail to complete the warranty card, the warranty will be activated on date of shipment from NAT.
Note: An appropriately rated facility, e.g. Certified Aircraft Repair Station, must install this equipment in accordance with applicable regulations. NAT Ltd’s warranty is not valid unless the equipment is installed by an authorized NAT Dealer. Failure to follow any of the installation instructions, or installation by a non-certified individual or agency will void the warranty, and may result in a non-airworthy installation.
2.3Installation Procedures
2.3.1Warnings
Do not bundle any lines from this unit with transmitter coax lines. Do not bundle any audio or DC power lines from this unit with 400 Hz synchro wiring or AC power lines. Do not position this unit or wiring from this unit next to any device with a strong alternating magnetic field such as an inverter, or significant audio interference will result.

2.3.2Cautions
In all installations, use shielded cable exactly as shown and ground as indicated.
Significant ground loop and noise problems may result from not following these guidelines.
The shielding and routing of the receive audio lines used in the AA30-301 installation is very critical and poor performance of the aircraft audio system will result if the installation shown on Interconnect drawing AA30\301\403-0 and -1 is not followed.
2.3.3Cabling and Wiring
All unshielded wire shall be selected in accordance with AC43.13-1B Change 1,
Paragraphs 11-76 through 11-78. Wire types should be 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 wiring diagrams in Section 2.6 as required.
Allow 3 inches from the end of the wire to the shield termination to allow the hood to be easily installed. Note that the hood is a ‘clamshell’ hood, and is installed after the wiring is complete.
All wiring should be at least 22 AWG, except power and ground lines, which should be at least 20 AWG. Ensure that all ground connections are clean and well secured.
2.3.4Post-Installation Checks
2.3.4.1 Voltage/Resistance Checks
Check the following:
a)P101 pin <13> for +28 Vdc avionics buss voltage.
b)P101 pin <12> for +28 Vdc lighting buss voltage.
c)P101 pins <15> <16> <18> <20> <22> and <25> for continuity to ground (power).
d)P101 pin <24> for continuity to ground (lighting).
2.3.4.2Power On Checks
WARNING:
High volume settings can cause hearing damage.
Set the headset volume control to the minimum volume setting prior to conducting audio tests, and slowly increase the headset volume level to a comfortable listening level.
