JA95-002 Audio Controller – Six Transceiver
SECTION 1 - DESCRIPTION
1.1 System Overview
The JA95-002 audio controller is a centralized audio management system that distributes and controls all transceiver,
receiver and alert audio in an aircraft. It enables the selected transmission of microphone audio to a transceiver and
distributes all intercom audio.
The JA95-002 audio controller can be used in a standalone configuration or a star configuration to prevent the loss of
the entire system due to the failure of one controller. It provides a passive emergency mode that directs the primary
user (pilot) to the COM1 transceiver, NAV1 receiver and Direct Audio 1 & 2.
The JA95-002 is set up on a per-installation basis using a configuration cable and a PC running the product
configuration tool to download system configuration settings via the front panel music / configuration connector (♫/io)
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 JA95-002 design.
1.2 Features Overvi e w
The JA95-002 features a 37-pin D-Sub connector, which interfaces with the radio receive audio and crew phones, a
50-pin D-Sub connector which interfaces with the power and passenger headset connections. This layout minimizes
crosstalk and follows industry standard interconnect for multi-user Audio Controllers.
Many of the 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 alert audio feature is intended for use as a secondary alerting
system where another device provides the primary annunciation.
The JA95 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 (2 on one toggle switch and 3 on the other).
The JA95 features individual VOX gating, and supports two Direct Audio inputs to provide audio at a fixed level to the
users.
The JA95 has a CVR output and a two channel Alert Generator. Each alert has a separate key input.
The JA95 allows transmit access for three crew members (Pilot, Co-pilot and Passenger 1).
A Music / Configuration connector is provided on the faceplate of the JA95 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 has two modes of operation: Normal Mode and Emergency Mode.

(5)Multi-function (Transmit/ICS) Switch
This is a green two-position centre-off momentary toggle switch.
When in the default XMIT/ICS configuration, this switch acts as
the pilot’s ‘Press-to-talk’ (PTT) button. The unit will transmit on
the selected transceiver when the switch is held in the ‘up’
position, and when held in the ‘down’ position, it will transmit on
the intercom.
See section 3.3.7 below for Multi-function Switch operation.
Note: At installation, this switch may be configured to operate in default or alternative mode. Check with your
installing agency for confirmation of the operation of this switch. The legends 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.
(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

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 with
ambient noise.
(10)CALL Annunciator
This is a deadfront annunciator.
When enabled, it will illuminate when a ground is applied to
the CALL input from another user’s audio controller or by an
external ‘call’ button.
The default legend is 'CALL', but it is interchangeable to
allow customization.
Note: Check with your installing agency for confirmation of the operation of this annunciator. The legends
are interchangeable 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.

Installation and Operating Manual
3.3 Normal Operation Mode
Note: Numbers in parentheses refer to the front panel controls shown in section 3.2.
The JA95-002 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.
3.3.2 Receiving
When the JA95-002 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 incoming transmissions is set 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 COM 1, COM 2, AUX, FM 1, FM 2, or FM3. The corresponding Transmit
Select annunciator will illum inat e.
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 configurat io n with the ins ta lling 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 FM 2 transmitting. A second
momentary activation of the TX PTT, or moving the Transmit Selector away from FM 2, will stop the FM 2 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.
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 (12).
Note: At installation, this switch may be configured to operate in default or alternative mode. Check with your
installing agency for confirmation of the operation of this switch.
Default Operation
When in the default XMIT/ICS configuration, this switch acts as the pilot’s ‘Press-to-talk (PTT) button. The unit will
transmit on the selected transceiver when the switch is set to the ‘up’ position, and when set to the ‘down’ position, it
will transmit on the intercom.
Alternative Operation
This switch may be configured to provide a ground signal to operate other equipment.
3.3.8 Music Operation
Music to the phones will be muted by incoming audio (ICS, Receive, Direct or Alert Audio) or if the unit is transmitting.
When the incoming audio has ended, the music will gradually return to the previous level.
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 COM 1 transceiver, NAV 1
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 COM 1 transceiver. No other function in the JA95 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, the sum of the COM 1 receive, NAV 1 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 COM 1 transceiver.
The pilot is disconnected from the ICS. The COM 1 transceiver and NAV 1 receiver and DIRECT AUDIO are not
available to the other users. All other functions of the JA95 will operate. The LEDs, legends and annunciators will
retain normal functionality.
