without the necessity of removing the unit from the panel. To facilitate future customizations and certification, no
software or complex electronic devices are used in the JA95-N42 design.
1.2 Features Overview
Many of the JA95-N42 input and output levels are adjustable, several audio paths are selectable, and alert audio
analog waveforms can be loaded using the configuration program ProCS™ (Product Configuration Software) to write
configuration commands via the JA99-001 configuration cable to the front panel music / configuration connector. The
audio waveforms are stored in non-volatile devices.
The JA95-N42 provides intercom functions for up to seven users. It supports up to 6 transceivers, each selectable
from a rotary switch, and up to 5 receivers (two on one toggle switch and three on another).
The JA95-N42 features individual VOX gating, and supports two Direct Audio inputs to provide audio at a fixed level to
the users.
The JA95-N42 has a CVR output and a Call Alert Generator.
The JA95-N42 allows transmit access for two crew members (Pilot and Co-pilot).
A Music / Configuration connector is provided on the faceplate of the JA95-N42 for configuration of audio levels and
routing. The port can also be used as a music input and is compatible with most music players.
The JA95-N42 has two modes of operation: Normal Mode and Emergency Mode.
The JA95-N42 is NVIS Type I Class B compliant.
The JA95-N42 has a Passenger Receive Isolation switch.

JA95-N42 Audio Controller - Passenger RX ISO - NVG
(1) Transceiver Select Switches and Legends
The Transceiver Receive Switches are six white
two-position toggle switches. When a switch is
set to the ‘up’ position, audio from the
associated transceiver is routed to the phones.
The legends (above the switches) are
interchangeable to allow customization.
(Default – COM1, COM2, AUX, FM1, FM2,
FM3.)
(2) Receiver Select Switches and Legends
These are two blue three-position centre-off toggle switches.
When a switch is set to the ‘up’ or ‘down’ position audio from
the selected receiver is routed to the phones.
The legends (three above and three below the switches) are
interchangeable to allow customization. (Default – NAV1,
NAV2, ADF, M/D.)
Installation and Operating Manual
Note: The M/D switch position is used to select both Marker (MKR) and Distance Measuring Equipment
(3) Receive Volume Control
This is a rotary knob that adjusts the phones volume of the
receive audio from minimum (CCW) to maximum (CW).
Individual radio volume controls should be set to a nominal level,
and then adjusted for changing flight conditions using this
control.
(4) Mode Switch
This is a red two-position locking toggle switch. When
set to the ‘up’ position, the unit is Emergency mode,
and when set to the ‘down’ position, the unit is in
Normal mode. The legends are interchangeable to
allow customization. (Default – EMER, NORM.)
(DME).
The switch is lockable to prevent accidental changing of
the mode. The switch must be lifted to release the lock.
For full information on Emergency and Normal Mode
operation, see sections 3.3 and 3.4 below.
Rev A Page 17
JA95-N42 Audio Controller - Passenger RX ISO - NVG
(5) Passenger RX Isolation Switch (PXRX/ISO)
This is a yellow two-position toggle switch labeled PXRX/ISO
that enables or disables the Receive Audio to the Passenger
phones.
When the switch is in the PXRX (up) position, the Passengers
can hear audio from any selected receiver. When the switch is in
the ISO (down) position, the Passengers are isolated from the
receive audio
The default legends are ‘PXRX' and 'ISO', but they are
interchangeable to allow customization.
(6) Music/Configuration Connector (♫/io)
This is a music input that is compatible with most music players.
It accepts a 3 pole 3.5mm stereo plug with a slim diameter
connector housing.
Installation and Operating Manual
(This connector is also used during installation to change
configuration settings.)
CAUTION: If an unapproved connector or cable is used, damage to the unit or to any attached device may
occur. If in doubt, contact JAC for a list of approved cables, music sources and devices.
(7) Transmit Annunciator - TX
This is a deadfront annunciator that will
illuminate when the JA95-N42 is transmitting.
The default legend is ‘TX’, but it is
interchangeable to allow customization.
(8) Transmit Selector
This is a rotary six-position control that is used to
select transmission via one of the six transceivers.
Each of the transmit selector positions is linked by
a white line to the corresponding transmit select
annunciator, transceiver switch and legend.
Rev A Page 18
The appropriate annunciator will light green to
show which transceiver is selected for transmit ‘FM3’ in this example.

Installation and Operating Manual
(9) VOX Threshold Control
This is a rotary knob that is used to select the VOX
threshold of the unit. See below.
When rotated fully clockwise (cw), the threshold will be
at maximum and VOX ICS operation is disabled and ICS
PTT input is required for ICS operation.
When rotated fully counterclockwise (ccw), the threshold
will be at minimum (almost live).
To adjust the unit for VOX (Voice activated) use, the VOX control should be set fully ccw and then slowly rotated cw to
the point where no intercom audio can be heard. The VOX control should be adjusted for proper operation according
to the ambient noise.
(10) CALL Annunciator
This is a customizable deadfront annunciator activated
by an external switch.
It illuminates when a ground is applied to the CALL
ANNUNCIATOR input from another user’s audio
controller (for example the JA95-N32 Med Crew Audio
Controller CALL switch) or by a remote ‘call’ button
within the aircraft.
Note: Check with your installing agency for confirmation of the operation of this annunciator. The legend is
replaceable to allow customization.
(11) ICS Volume Control
This is a rotary control used to adjust the volume of all
ICS audio to suit the ambient conditions. Rotating the
control completely cw gives rated level, and completely
ccw reduces the output to minimum level.
3.3 Normal Operation Mode
Note: Numbers in parentheses refer to the front panel controls shown in section 3.2.
The JA95-N42 is in Normal mode when the front panel EMER / NORM switch (4) is in the NORM position and suitable
electrical power is supplied to the unit.
3.3.1 Panel Lighting
The legends and annunciators will be illuminated (when appropriate) and dim through the aircraft lighting buss.
Rev A Page 19
JA95-N42 Audio Controller - Passenger RX ISO - NVG
Installation and Operating Manual
3.3.2 Receiving
When the JA95-N42 receives an incoming transmission on a transceiver or receiver that has been selected, either by
the white transceiver receive switches (1) or the transmit selector (8), the incoming audio will be directed to the user’s
phones.
The audio level of any incoming transmission will depend upon the level selected by the front panel RX volume control
(3). It will be muted if the unit is transmitting and muting of receive audio during transmit is enabled.
3.3.3 Transmitting (Transmit Operation)
To select a transceiver, rotate the Transmit Select Switch until it aligns with the line leading to the Transceiver Select
switch legend (see 1) - default legends COM1, COM2, AUX, FM1, FM2, or FM3. The corresponding Transmit Select
annunciator will illuminate.
When the user’s TX PTT is activated, the unit will transmit on the selected transceiver, and the deadfront Transmit
Annunciator (7) will illuminate ‘TX’. All MIC and sidetone audio will be routed to the user’s phones, and any music will
be muted for the duration of the transmission.
3.3.4 FM2 PTT Operation
Note: If the FM2 transceiver has been configured as duplex, it can be used with a cellphone or
sat-phone. Check your configuration with the installing agency.
If the unit has been configured for cellphone or sat-phone use and FM2 has been selected for transmit, momentarily
activating the TX PTT (either from the faceplate or by some other method) will keep the FM2 transmitting. A second
momentary activation of the TX PTT, or moving the Transmit Selector away from FM2, will stop the FM2 from transmitting.
3.3.5 VOX Operation
A user’s MIC audio is routed to the ICS when the MIC audio level exceeds the VOX threshold.
A user’s MIC audio is disconnected from the ICS when the MIC audio level falls below the VOX threshold for 0.5 to 2
seconds.
3.3.6 ICS Operation
ICS audio is the sum of all the MIC audio from users with ICS KEY active or with MIC audio level exceeding the VOX
Threshold level.
The ICS audio also includes the audio input on the ICS TIE from other Audio Controllers unless isolation status (ISO)
has been selected on the ISO/ALL switch.
The ICS audio is output on the phones of each user.
The ICS audio is muted during transmit.
The ICS audio level at the phones is controlled by the ICS volume control (11).
3.3.7 Call Annunciator Operation
When another audio controller's CALL SWITCH output signal (i.e. from a JA95-N32) is connected to the JA95-N42's
CALL ANNUNCIATOR input signal then the JA95-N42's CALL ANNUNCIATOR will illuminate and the CALL ALERT
aural message will be played when the other audio controller's CALL switch is operated.

3.4 Emergency Operation Mode
Emergency mode can be selected by the Mode switch on the front panel, or entered automatically if power to the unit
is lost.
3.4.1 Auto Emergency Mode
If the unit is in emergency mode because power has been lost to the unit, the sum of the COM1 transceiver, NAV1
receive, and DIRECT AUDIO will be routed to the pilot’s phones and the CVR. The pilot's microphone and transmit
key are connected to the COM1 transceiver. No other function in the JA95-N42 will operate when power is lost. All
indicator LEDs, legends and annunciators will be dark.
3.4.2 Selected Emergency Mode
If the unit is in emergency mode because the EMER / NORM switch is in the EMER position and sufficient power is
applied to the JA95-N42, the sum of the COM1 receive, NAV1 receive, DIRECT AUDIO and Alert audio will be routed
to the pilot’s phones and the CVR. The pilot's microphone and transmit key are connected to the COM1 transceiver.
The pilot is disconnected from the ICS. The COM1 transceiver and NAV1 receiver and DIRECT AUDIO are not
available to the other users. All other functions of the JA95-N42 will operate. The LEDs, legends and annunciators will
retain normal functionality.

in multiple different configurations with only minimal changes.
The internal circuitry ensures that, although the legends are individually
illuminated, the illumination is consistent and uniform throughout all legends, and
never needs to be balanced. This means that if it is a requirement to change the
labelling due to damage or for a different project, there is no need for costly and
time-consuming illumination checks.

Legend Replacement
To replace a legend, align the text correctly, and then apply gentle pressure until the body of the legend support seats
firmly into the faceplate.
Once the new legend is in place, ensure that it has seated correctly by checking that it illuminates. The unit is now
ready for use.
