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 fr
ont 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.
