Section 1.0 Description
1.1 Introduction
Information in this section consists of product description, design features and specifications for N335-
001, N335-002, N335-201, and N335-202 Audio Controllers. All derivative product information shall be
contained in the applicable manual supplement, which may be obtained from AEM as required. Review
all notes, warning and cautions.
1.2 Purpose of Equipment
The N335 audio controllers are compatible with military and civil aviation headsets. The N335 controls the
audio from multiple receivers, and allows transmission of mic audio to a selected transmitter. VOX intercom
operation is also proved on a proprietary tie line to multiple units. A fully redundant backup system is selectable
from the front panel, and a CVR output is provided.
1.3 Design Features
The N335 is a Dzus rail mounted audio controller with various faceplate lighting options. The N335 has a
composite Radio Audio output to provide monitoring capabilities for additional users. It can be configured
in the field to suit various commercial and military headsets, and microphone outputs. Receive Audio
inputs and Direct Audio inputs are adjustable to suit installation requirements. Emergency mode
operation provides switching to a fully redundant back-up system that provides full performance. A front
panel annunciator provides indication that the EMER mode is active.
N335-001 The N225-001 Audio Controller has a NVIS Green ‘A’ lighted front panel. It
provides radio transmit and receive audio select capability for the cockpit position.
It will support four microphone types a standard –dynamic 5-ohm, dynamic 75-
ohm, dynamic 150-ohm and amplified dynamic 150-ohm types. It provides NAT
ICS tie line capability from 1 to 4 loads. Transmit capability is provided for two
users (user 1 and user 2), and an annunciator on the front panel indicates
transmit status. It provides common intercom functions for up to two headset
stations, and allows for intercom capability to other audio controllers via an ICS
Tie Line. A CALL annunciator advises the operator that other users in the system
need to communicate, if they are in an ‘isolate’ mode.
N335-002 The N335-002 Audio Controller has an NVIS Green ‘A’ lighted front panel. It
provides radio transmit and receive audio select capability for the Crew position.
The crew position is restricted in its radio capability to the ‘communication’ radios.
It also provides common intercom functions for up to two headset stations, and
allows intercom capability to other audio controllers via the ICS Tie Line. A CALL
switch allows the operator to signal other users in the system that they need to
communicate, if they are in an ‘isolate’ mode.

N335-201
The N335-201 Audio Controller is identical to the N335-001, but with ‘deadfront’
CALL, EMEER and TX text annunciators on the front panel. It will support only
two microphone types as standard
–dynamic 5 ohm and amplified-
dynamic 150
ohm. It provides
NAT
ICS tie line capability from 2 to 4 loads, with one switch
position functioning to enable Super
NAT
ICS tie line operation, which maintains
the rated output level independent of the number of units connected to the tie
line. It may be configured to provide auto emergency power mode switchover,
ICS tie line muting during transmit, and pilot over copilot transmit priority.
N335-202
The N335-202 Audio Controller is identical to the N335-002, but with ‘deadfront’
text annunciators on the front panel. It will support only two microphone types as
standard
–dynamic 5-ohm and amplified dynamic 150 ohm. It provides NAT
ICS
tie line capability from 2 to 4 loads, with one switch position functioning to enable
Super
NAT
ICS tie line operation, which maintains the rated output level
independent of the number of units connected to the tie line. It may be
configured to provide auto emergency power mode switchover, ICS tie line
muting during transmit, and pilot over co-pilot transmit priority.

2.4.1 Warnings
WARNING:
High volume settings can cause hearing damage.
Set the headset volume control to the minimum volume setting prior to
conducting tests, and slowly increase the headset volume to a
comfortable listening level.
2.4.2 Cautions
CAUTION:
Do not remove compone
nts from the product while the unit is turned on. This
could cause damage to the component or unit.
Do not bundle any lines from this unit
with transmitter coax lines. Do not
bundle any logic, audio, or DC power lines from this unit with 400 Hz synchro
wi
ring or AC power lines. Do not position this unit next to any device with a
strong alternat
ing 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 as indicated
.
Significant problems may result from not following these guidelines.
All audio installations can be seriously degraded byincorrect wiring and shielding, and
may result in abnormal cross
-talk, hum and ground-loop noise. Be especi
ally careful
with all microphone wiring and tie line wiring, as these lines carry the lowest level
signals in the aircraft.
The intercom tie lines should also be properly termi
nated with either the
appropriate number of additional units, or with a load
resistor. See section
2.
4.4, Tie Lines.
In all installations that use the Dynamic microphone capability of the N335,
extreme care must be taken with the shielding and routing of the microphone
wiring. This is especially true of the 5
-ohm Dynamic mic inp
ut, where typical
signals are in the range of 100
-250 μVrms. Special wire with Mumetal
shielding should be considered if there are any concerns about installation
-
related noise.
Do not bundle the microphone wiring with high-level lines
(headphone, radio
audio, coaxial cables, etc.).
Headset and/or helmet wiring may also need to be reviewed if using Dynamic
microphones. Many of the headsets and helmets on the market have minimal
shielding for the wiring associated with the mic and phone circuits. Those with
shielded wiring often use the Phone Lo connection for the shield ground. In the
N335, the Phone Lo connection is not ground referenced, so the shielding has
no effect. This will result in substantial coupling of the Phone signal onto the
Microphone wires, leading to high levels of crosstalk in the intercom system.
These shielding considerations also apply to in
-
line PTT cordsets. If a review
of the headset wiring indicates there will be a problem with the shield
termi
nation, it is acceptable to ground the Phone Lo connection to a local
ground at the headset jack/connector.

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. Reference 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 Tie Lines
2.4.4.1 N335-001/-002
When no other unit is to be connected to the tie-line, set the ICS TIE ADJUST switch to the '1 NAT LOAD'
position (position 1), and connect a 1.8 k:resistor between the ICS TIE HI and ICS TIE LO lines (refer to
the appropriate drawings listed in section 2.7).
2.4.4.2 N335-201/-202
When no other units are to be connected to the tie-line, set the SUPER TIE SELECT switch to the 'NAT
TIE' position (position 0), set the NAT TIE SELECT switch to the '2 NAT LOADS' position (position 1), and
connect a 910 :resistor between the ICS TIE HI and ICS TIE LO lines (refer to the appropriate drawings
listed in section 2.7).
2.4.5 Mechanical Mounting
The N335 can be mounted vertically or horizontally in standard Dzus rails.
Before the unit is mounted, make all functional tests, and trimpot adjustments. Be sure the harness has
enough clearance to permit the unit to be pulled out for re-adjustment, if needed later. Make sure unit is
securely fastened to the Dzus rail, and that the connector locks are tightened before any flight is
attempted.

2.4.6 Post Installation 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 to a
comfortable listening level.
2.4.6.1 Voltage/Resistance Checks
These instructions apply to all N335 models unless otherwise indicated. Do not attach the N335 until the
following conditions are met.
Check the following:
a) P102 pins <1>, <2> and <8> for +28 Vdc relative to ground.
b) P102 pins <3>, <9>, <10> and <11> for continuity to ground.
2.4.6.2 Power On Checks
Power up the aircraft’s systems and confirm normal operation of all functions of the N335. Refer to
Section 3 (Operation) for specific operational details.
a) Turn on the radios and accessories required for the system.
b) Check for correct radio audio and adjust for acceptable level.
c) Run through all installed functions, and check the ICS and TX functions for all users. Refer to
Section 3 for specific operation details.
Notes: Significantly different headsets may have different mic characteristics.
The David Clark M-7 mic is much more active than the M-4 or M-1 mics, and may
aggravate headset imbalance if used in a mixed system.
d) If any preset requires adjustment, be sure this is carried out before the aircraft leaves, and that
the unit and its mating connector are secured before departure. Make all required log book
entries, electrical load, weight and balance amendments and other paperwork as required by your
local regulatory agency.
Note: The unit is shipped from the factory with all internal adjustments set to the normal test levels. Once
installed in the aircraft, it may be desirable to change some of these settings to best suit the local
operating environment. See Section 2.5 for adjustment information.
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.
