EQUIPMENT DESCRIPTION
The SL15-CD Audio Control Panel is a state of the art audio isolation amplifier and audio selector that
contains an automatic voice activated (VOX) intercom system. It can switch up to three transceivers (Com
1, Com 2 and Com 3) and six receivers (Nav 1, Nav 2, ADF, DME, MKR and AUX).
A duplex COM 3 mode (selectable at installation) allows the SL15-CD to act as an audio interface between
aircraft headphone and microphones and specific aircraft approved (FAA/FCC) cellular telephone equipment.
Warning: Use of non-aviation approved cellular telephone equipment may be prohibited by regulation.
UPS Aviation Technologies is not responsible for unauthorized airborne use of cellular telephones.
For airborne use, the SL15-CD must be interfaced with an approved system.
There are two unswitched inputs, for autopilot disconnect, and/or radar altimeter warning. Push buttons
select the receiver audio source provided to the headphones. A SPR button allows the user to listen to the
receiver(s) selected on the cabin speaker. Except for the unswitched inputs, all speaker audio is muted during transmit.
Push button switches selects one of the communication transceivers for the pilot and copilot position, and
allows radio transmission. In "Split Mode" the SL15-CD has the ability to allow the pilot and copilot to
operate different transceivers independently. The Com 3/TEL mode (selected at installation) allows the pilot to use the audio panel for duplex operation, such as with aviation-specific cellular telephones. External
switches permit telephone operation for the copilot and passengers.
A fail-safe mode connects the pilot headphone and microphone to COM 1 if power is removed for any reason, or if the power switch is placed in the Off (Fail-safe) position.
A six-station voice activated (VOX) intercom is included in the SL15-CD. This system has PS Engineering’s exclusive IntelliVox® circuitry that eliminates manual adjustments. The system contains six separate
VOX mic circuits, and only opens the microphone channel in use.

2.3
Equipment Installation Procedures
2.3.1
Cooling Requirements
Forced air-cooling of the SL15-CD or the CD-15 remote player is not required. However the units should
be kept away from heat producing sources (i.e. defrost or heater ducts, dropping resistors, heat producing
avionics) without adequate cooling air provided.
2.3.2
Mounting Requirements
The SL15-CD must be rigidly mounted to the instrument panel of the aircraft structure and within view and
reach of the pilot position(s). Installation must comply with FAA Advisory Circular AC 43.13-2A. The unit
may be mounted in any area where adequate clearance for the unit and associated wiring bundle exist.
The CD-15 CD Player may be located in any convenient location for access to the disc slot. However, it
should be mounted to keep the interconnecting bundle within approximately six feet (2 meters). The unit
must be installed within `30° of horizontal along the pitch axis, and `10° of horizontal along the roll axis in
level flight.
Avoid installing the units close to high current devices or systems with high-voltage pulse type outputs,
such as DME or transponders. Avoid running the interconnecting bundles near any high current wires.
2.3.3
Audio Panel Mounting Rack Installation
Remove the unit from the mounting tray by unscrewing the 3/32" hex-head screw that is in the center of the

2.5
Cable Harness Wiring
Referring to the appropriate Appendix, assemble a wiring harness as required for the installation. All wires
must be MIL-SPEC in accordance with current regulations. Two- and three-conductor shielded wire must
be used where indicated, and be MIL-C-27500 or equivalent specification. Proper stripping, shielding and
soldering technique must be used at all times. It is imperative that correct wire be used.
The 6-conductor cable for the remote CD-15 is available from PS Engineering as part number 800-0220609.
Refer to FAA Advisory Circular 43.13-2A for more information. Failure to use correct techniques may result in improper operation, electrical noise or unit failure. Damage caused by improper installation will void
the UPS Aviation Technologies warranty.
NOTE: PS Engineering can make a custom wiring harness for the intercom and CD player portion. Call 1800-ICS-AERO or see www.ps-engineering.com for details.
2.5.1
Noise
Due to the variety and the high power of radio equipment often found in today's general aviation aircraft,
there is a potential for both radiated and conducted noise interference.
The SL15-CD power supply is specifically designed to reduce conducted electrical noise on the aircraft
power bus by at least 50 dB. Although this is a large amount of attenuation, it may not eliminate all noise,
particularly if the amplitude of noise is very high. There must be at least 13.8 VDC present at the bottom
connector, pin 20, of the SL15-CD for the power supply to work in its designed regulation. Otherwise, it
cannot adequately attenuate power line noise. Shielding can reduce or prevent radiated noise (i.e., beacon,
electric gyros, switching power supplies, etc.) However, installation combinations can occur where interference is possible. The SL15-CD was designed in a RFI hardened chassis and has internal Electromagnetic
Interference (EMI) filters on all inputs and outputs.
Ground loop noise occurs when there are two or more ground paths for the same signal (i.e., airframe and
ground return wire). Large cyclic loads such as strobes, inverters, etc., can inject noise signals onto the airframe that are detected by the audio system. Follow the wiring diagram very carefully to help ensure a
minimum of ground loop potential. Use only Mil Spec shielded wires (MIL-C-275000, or better). Under no
circumstances combine a microphone and headphone wiring into the same shielded bundle. Always use a 2or 3-conductor, shield wire as shown on the installation wiring diagram.
Radiated signals can be a factor when low level microphone signals are "bundled" with current carrying
power wires. Keep these cables physically separated. It is very important that you use insulated washers to
isolate the ground return path from the airframe to all headphone and microphone jacks.
Adding a high-performance audio control system, particularly in conjunction with high-performance active
noise-canceling headsets, cannot improve on older avionics that were designed for cabin-speaker use. UPS
Aviation Technologies makes no claim that the audio panel will provide a noise-free audio quality under all
installation conditions, particularly with older avionics.
2.5.2
Existing KMA-24 Installation
If the installation replaces a KMA-24 (series -01, -02 or -03), the existing 44-pin connector can be used for
the bottom connector of the SL15-CD tray as is, providing it is properly installed and wired. No other
changes are required except for external marker lights (see Section 3.7.2 for details). The "key" in the existing connector must be located between pins 7 and 8. This connector will be used in the bottom connector
position. (See Appendix for complete wiring harness details.)
The existing ground bus may be reused for radio shield connections, if it was constructed so it can be relocated to the SL15-CD tray.

Installation Manual
2.5.3
Existing SL10/SL15 installations
In 28-Volt aircraft, the dropping resistor may be removed, however, the 2 Amp breaker should be changed
to 3 Amp. If the old unit is stereo (SL10S or SL15), no rewiring is necessary except to add additional features.
2.5.3.1
Stereo SL15-CD installations into monaural SL10 or SL10M
Installations replacing SL10 or SL10M require re-wiring of the top connector to accommodate the stereo
configuration. See appendixes for detailed interconnect information.
2.5.4
Power
The SL15-CD is compatible with both 14 and 28 Volt DC systems. A two (2) Amp circuit breaker is required for 14 VDC installations, and a three (3) Amp breaker for 28 VDC aircraft. Power and ground wires
must be a twisted #18 AWG pair. Connect airframe power ground to J1 (bottom connector) Pin Z only. No
dropping resistors are required.
2.5.5
Communications Push-to-Talk
An important part of the installation is the PTT (Push-To-Talk) switches that allow the use of your aircraft
communications radio for transmissions. There are three typical configurations that can be used. Select the
case that best fits the installation. Only the person who presses their PTT switch will be heard over the radio. If the pilot and copilot both use the PTT, only the pilot position has access to the radio. The pilot position will have PTT control regardless of the mic selector switch or copilot PTT when the SL15-CD is in the
OFF/EMG mode.
CASE I: PTT is built into both pilot and copilot yokes.
CASE II: PTT is in pilot yoke only. This configuration requires a modified external PTT switch plugged
into the copilot's microphone jack. (See Appendix A). When the copilot's PTT is pressed, the intercom
switches the microphone audio from pilot to copilot mic.
CASE III: No built in PTT. This requires two built in PTTs to be installed, or modified external PTT
switches to be used. Modify external PTT as required. See Appendix A.
2.5.6
Audio Panel interface
The SL15-CD is designed to interface with standard aircraft avionics, and presents a 500W receiver impedance. For best results, a twisted-shielded cable is recommended from the avionics audio source to the audio
panel, with the shield grounded at the audio panel end.
Some avionics do not provide a separate audio low, and may introduce additional electrical noise into the
system. For best results, connect the audio low from the audio panel to the radio ground, using one conductor of the twisted-shielded cable.
2.5.6.1
Speaker Load
The SL15-CD contains a speaker amplifier. Some units with internal speaker amplifiers, such as the King
Radio KX170-series, require a resistive load to prevent damage if their speaker amplifier is not used. Connect the speaker output from the unit to the load input on the SL15-CD (J1, pins 19 and L, 16 and M. The
speaker load is 16 W, 3W.
2.5.7
Com 3 Duplex (TEL) Function
As installed in the standard configuration, the SL15-CD Com 3 function operates conventionally. Pushing
the Com 3 Xmt button places the receive audio from Com 3 in the headset and applies the pilot or copilot
microphone to the Com 3 when the appropriate PTT is activated.
If J2, Pin J is connected to aircraft ground, the SL15-CD is forced into Com 3-Duplex mode. This mode is
designed to operate with telecommunications systems, such as the AirCell AGM.01. Audio streams selected
by hook switches are provided to the COM 3 output, the PTT for Com 3 is inactive, and audio from Com 3

is presented to the headset. This allows a telephone-like audio interface. The COM 3 input and output are
compatible with aviation radios.
Unauthorized use of unapproved cellular telephone devices in aircraft is subject to FCC enforcement
action, which may include a $10,000 fine per incident. UPS Aviation Technologies, Inc. does not endorse using unapproved cellular telephone equipment in flight, and takes no responsibility for the
user’s action.
2.5.8
Transmit Interlock
Some communications transceivers use a transmit-interlock system. To fully utilize the Split Mode feature,
this function must be disabled. Consult that manufacturer's installation manual.
2.5.9
"Swap" Mode
When a momentary, normally open, push-button switch is connected between pin 10 on the top connector
and aircraft ground, the user can switch between Com 1 and 2 by depressing this switch without having to
turn the mic selector switch. This yoke-mounted switch eliminates the need to remove your hands from the
yoke to change transceivers. The transfer of TX indication from Com 1 to Com 2 shows that the swap has
been initiated, there is no dedicated swap indicator.
2.5.10 Backlighting
The SL15-CD has an automatic dimming of the pushbutton annunciator LEDs and marker lamps controlled
by a photocell. Control of the unit backlighting is through the aircraft avionics dimmer. Connect the dimmer
control line to J1 pin D for 14 volt systems, and to J1 pin F for 28 volt systems. Pin E is light ground.
If an external dimmer control is not used, a constant low level back light illumination can be established for
nighttime viewing. Pin D or F (depending on system voltage) must be tied to power (J1, pin 20) for the back
lighting system to work. The photocell mounted in the unit face will automatically adjust the intensity of the
push-button annunciator LEDs.
2.5.11 Unswitched inputs
J1, pin T is the unswitched input number 1 and J1 pin 17 is unswitched input 2. These inputs are presented
to the pilot and copilot regardless of the audio configuration, and will always mute the entertainment inputs.
These 510Ω inputs can be used for altimeter DH audio, GPS waypoint audio, autopilot disconnect tones,
air-to-ground (Flitefone) telephone ringer or any other critical audio signal. This input is not related to the
cellular telephone interface.
2.5.12 PA Mute (J1, Pin 18)
Pin 18 of J1 is a TTL logic output that is pulled low during PTT operation. This serves as an input to external public address system to prevent feedback during transmissions.
2.5.13 Public Address Function (J2, Pin 18)
By connecting the top connector (J2), Pin 18 to ground, the pilot’s microphone audio is placed on the cabin
speaker output. When the pilot’s PTT is activated, his voice is heard over the speaker. The copilot can continue to use the selected com.
We recommend installing a toggle switch to connect the cabin speaker output (pin W, bottom connector) to
a rear or public address speaker instead of the cockpit speaker close to the pilot. This will prevent feedback.
2.5.14
Control Output (J2, Pin A)
Pin A of the top connector is pulled to ground whenever the AUX button is depressed. This serves as a
control line for external devices, such as a entertainment system that the pilot wishes to control.
This could be used in conjunction with a PA to control J2, Pin 18, as well as an external relay to change to
the cabin speaker from the cockpit.

SL15-CD Series Audio Selector Panel and Intercom System
Installation Manual
2.5.15 Intercom wiring
The top connector (J2) is for the intercom, CD interface and additional functions. See Appendix for intercom connection configurations. It is critical to the proper operation of this system to have this connector
wiring made in accordance with these diagrams. Use 2- and 3-conductor, MIL-spec cable as shown. Connect the shields at the audio panel end only, and tie to the audio low inputs as shown.
NOTE: The top connector harness can be custom made by PS Engineering, Inc. Simply call the factory and
obtain a wire harness work sheet. The harness will be made to your specifications and fully functionally
tested. All hardware is included.
2.5.16 Remote CD wiring
The remote CD-15 Player is powered from the avionics bus through a 1 A PULL TYPE Breaker.
The CD-15 is interfaced to the SL15-CD through a 6-conductor data cable and a 3-conductor audio cable.
These cables must conform to the MIL-C-27500.
2.5.16.1 Entertainment Input
The remote compact disc player is designed to interface with the audio panel as input number 1 J2 pins 15
(left channel) and 16 (right channel), WRT pin T, and is provided to the pilot and copilot. Entertainment
number 2 is provided to the passengers at all times.
In order to use the remote player to provide music to the passengers, it must be interfaced to Entertainment
2 input pins 13 (right), 14 (left), WRT pin R. We recommend installing a DPDT switch to allow isolation of
the music sources if desired.
NOTE: Use the low level output of any additional entertainment device to connect to the audio panel.
Maximum signal level is 2 VAC p-p.
DO NOT use a speaker-level output, this will cause internal damage in the audio panel.
2.5.16.1.1 Entertainment muting
The SL15-CD incorporates a "Soft Mute" system. This will mute the entertainment devices during ICS or
radio conversation.
Any signal appearing in the unswitched audio inputs will always mute the entertainment sources, even
though the passengers may not hear the audio tone itself.
Caution: Local oscillators and internal signals from entertainment equipment other than the CD-15 can
cause undesired interference with other aircraft systems. Before takeoff, operate the entertainment devices
to determine if there is any adverse effect within the aircraft systems. If any unusual operation is noted in
flight, immediately switch off the entertainment devices.
All additional entertainment devices must be switched off for both takeoff and landing.
2.5.16.1.2 Entertainment 2 Mute (Pin V)
The ICS button on the SL15-CD controls the muting (“Karoake mode”) of entertainment source #1.
Connecting J2 pin V to ground through a SPST switch places the entertainment #2 music source into the
Karoake Mode. In this mode, incoming music and intercom conversation will not mute the music for the
passengers’ intercom net. This allows uninterrupted music during casual conversation and at times when
radio communications are of lesser importance.

Installation Manual
2.5.17 SL15-CD Intercom expansion (J2, Pins P, S, and C)
The SL15-CD contains a 6-place intercom. In applications where more intercom positions are needed, PS
Engineering can provide intercom expansion units, such as the IntelliPAX, part number 11606, 11606R,
etc. These can add up to six additional stereo intercom stations, plus independent music input. Interface to
the expansion unit is through J2, pins P (audio input from expansion unit), S (audio output to expansion
unit) and C (9 VDC expansion power).
2.6
Marker Beacon Installation
The marker beacon receiver is an option included in the SL15-CD.
2.6.1
Marker Antenna Installation
A marker beacon antenna, appropriate to the type and speed of the aircraft, is required (not included). Refer
to aircraft and antenna manufacturer's installation instructions, as well as AC43.13-2A (or later revision),
Chapter 3, for information on proper antenna installation techniques. The marker beacon antenna must be
mounted on the bottom of the aircraft.
2.6.2
External Marker Lights
For installations that require external marker beacon lights, there are three outputs that can drive 12-Volt lamps
only. The external output lamps are driven high (typically +9 VDC ±1.5 VDC unloaded, at MAX brightness)
when active. Maximum source current per lamp is 125 mA. Voltage varies with photocell dimming.
2.6.3
Middle Marker Sense
A Middle Marker Sense output signal is available from the SL15-CD to flight control systems. This function will not operate during the test mode. This output will go to +4.5 VDC (± 1.0 VDC) when a valid Middle Marker signal is received. This output is J1, pin 2.
2.6.4
Marker Audio Input
If using an external marker receiver, the audio input is J1, pin 21 (MKR input).
2.7
Adjustments
The SL15-CD is factory-adjusted to accommodate the typical requirements for most aircraft configurations.
There are five adjustments however, that will allow the installer to tailor the specific functions.

Communications Antenna Installation Notes
For best results while in Split Mode, it is recommended that the one VHF communications antenna is located on top of the aircraft while the other communications antenna is installed on the bottom. Any antenna
relocation must be accomplished in accordance with AC 43.13-2A, aircraft manufacturers’ recommendations and FAA-approved technical data.
Warning:
It is probable that radio interference will occur in the split mode when the frequencies of the two aircraft radios are adjacent, and/or the antennas are physically close together. UPS Aviation Technologies makes no expressed or implied warranties regarding the suitability of the SL15-CD in Split
Mode.
2.8.1
Hook Switches
While the mic selector button acts as the hook switch for the pilot, additional hook switches must be installed to have full access to the cell phone system. The copilot hook switch is a SPST switch that connects
pin L of J2 on the SL15-CD to ground to place the copilot mic audio on the Com 3 audio in duplex mode
for cell phone operation.
SL15-CD J2, pin M is the passenger hook switch. Install a SPST switch in a location adjacent to each passenger headset where cell phone use is desired. When pin M is connected to ground through any switch, the
passenger microphones are all on the Com 3/duplex system.
The hook switches are not active or required unless the audio panel is in Com 3 /Duplex mode, with pin J,
J2 grounded.
The wireless communication “tel” system utilizes an intercom loop. Therefore, any time the cell phone is in
use from the pilot or copilot side, pilot and copilot will lose intercom capability. In the ALL mode, when the
passengers’ activate the cell phone, the pilots will have intercom, and continue to hear and transmit over the
avionics normally. However the passengers will not have intercom, because they are on the telephone.

panel power off. The Com audio will be present in the right ear cup only.
Switch on the unit by pressing the volume (VOL) knob.
Check intercom operation.
Push the Com 1 Xmt select button (lower row).
Verify that both of the Com 1 buttons light. Verify that transmit button LED (Light Emitting Diode)
near the mic selector is not blinking. If the LED is blinking, stop testing and troubleshoot the microphone PTT installation.
Verify proper transmit and receive operation from the copilot position, noting that the copilot PTT
switch allows proper transmission on the selected transceiver. Verify that the Com 1 Xmt button blinks
when transmitting.
Verify that pushing the COM 2 button causes the button to illuminate, and the Com 2 receiver to be
heard. Verify operation on Com 1 from the pilot position.
Repeat for Com 2 and standard Com 3, (if installed).
Press and hold the Com 1 Xmt button. While holding the Com 1 button, press the Com 2 Xmt button.
This places the unit in “split Mode;” Verify that the pilot can transmit and receive on Com 1, while the
copilot transmits and receives on Com 2.
If the audio panel is installed with J2, pin J grounded, it is configured for duplex operation on Com 3.
Verify that the pilot headset is connected to the cellular telephone system (if installed). Verify that by
using the pilot side PTT, the pilot can transmit on the other selected radio (Com 1 or Com 2). Verify
that the Com 3 Xmt LED blinks at about twice the rate of com 1, to indicate a duplex mode. The copilot has radio transmit capability in Com3 duplex mode, on the selected Com ( 1 or 2). However, he will
have Com 3 capability if the copilot hook switch is grounded.
Verify proper operation of all receiver sources by selecting them using the appropriate button. The
button illuminates to show which source is in use.
Push the SPR button. Verify that all selected audio is heard in the cockpit speaker. Verify that the audio
mutes when the mic is keyed.

3.
Repeat with the unit in LOW sensitivity, with 430 mVolts applied.
Connect the marker antenna and verify proper operation.
2.11.2 Receiver Sensitivity
Although the SL15-CD meets FAA TSO-C35d sensitivity specifications, the sensitivity of the receiver has
been adjusted to meet real world requirements (150mV and 430mV, soft). This will usually eliminate the
need for the avionics shop to reduce the sensitivity in the field so as to prevent early detection of the marker
beacons. If your particular installation requires more or less sensitivity, see adjustment section 2.6, and figure 2-1.
2.12
Final Inspection
Verify that the wiring is bundled away from all controls and no part of the installation interferes with aircraft control operation. Move all controls through their full range while examining the installation to see
that no mechanical interference exists. Verify that the cables are secured to the aircraft structure in accordance with good practices, with adequate strain relief. Ensure that there are no kinks or sharp bends in the
cables and coaxial cables. Verify that the cables are not exposed to any sharp edges or rough surfaces, and
that all contact points are protected from abrasion.

GENERAL INFORMATION
3.1
SCOPE
This section provides detailed operating instructions for the UPS Aviation Technologies SL15-CD Audio
Selector Panel/Intercom Systems. Please read it carefully before using the equipment so that you can take
full advantage of its capabilities.
This section is divided into four sections covering the basic operating areas of the SL15-CD systems. They
are Audio Selector, Transceiver Selection, Intercom, and Marker Beacon Receiver.

3.2
Power Switch (EMG-Fail Safe Operation)
Unit power is turned on and off by pushing the volume knob. In the OFF or "EMG" position, the pilot is
connected directly to Com 1. This allows communication capability regardless of unit condition. Any time
power is removed or turned OFF, the audio selector will be placed in the fail-safe mode.
The power for the CD player (CD-15) is controlled by the audio panel. When the audio panel is on, it automatically activates the player. If it is necessary to disable the CD player, hold the two CD buttons (far right)
in for more than 2 seconds. This removes power from the CD-15 circuits. To re-enable the CD-15, cycle
power on the SL15-CD.
The power switch also controls the audio selector panel functions, intercom, CD player, and marker beacon
receiver.
3.3
Microphone (XMT) Selection (All models)
There are six pushbuttons associated with the communications transceivers. The lower buttons control
which transceiver is selected for transmit.
The SL15-CD gives priority to the pilot’s PTT. If the copilot is transmitting, and the pilot presses his PTT,
the pilot’s microphone will be heard over the selected com transmitter.
The SL15-CD has an automatic selector mode. Audio from the selected transceiver is automatically heard in
the headsets and speaker (if selected). You can check this function by switching from COM 1 to COM 2 and
560-0980-00
Page 3-1

UPS Aviation Technologies
SL15-CD Series Audio Selector Panel and Intercom System
Installation Manual
watch the selected audio light on the selector change from COM 1 to COM 2. This ensures the pilot will
always hear the audio from the transceiver he is transmitting on.
When switching from COM 1 to COM 2, while COM 2 audio had been selected, Com 1 audio will continue to
be heard. This eliminates the pilot having to switch Com 1 audio back on, if desired.
When switching from COM 1 to COM 2 while Com 2 has NOT been selected, Com 1 audio will be switched
off. In essence, switching the mic selector will not effect the selection of Com receiver audio.
When the duplex, or TELEPHONE, mode is implemented, Com 3 becomes the “TEL” position . This is the
pilot’s “hook” switch, when the system is interfaced to an appropriate approved wireless telecommunication
system, such as the AirCell system. Placing the mic selector in Com 3 places the pilot microphone and
headphones on the cell phone. The pilot PTT will switch the pilot mic to the other selected com transceiver,
and allow continued aircraft communications as well. The copilot will also be able to transmit with his PTT
as well.
NOTE: Placing the mic selector switch in the COM 3 –TEL– mode will disable pilot and copilot intercom,
as the intercom circuit is transferred to the telephone use. In crew or ISO mode, placing the switch in TEL
mode removes the passengers access to the telephone.
3.3.1
Swap Mode (Switch from Com 1 to Com 2 remotely)
With a yoke mounted, momentary switch, the pilot can change from the current Com transceiver to the other
by depressing this switch. To cancel "Swap Mode," the pilot may either press the yoke mounted switch
again, or select a different Com with the XMT buttons.
3.4
Audio Selector (All models)
Receiver audio is selected through seven momentary, push-button, backlit switches. You will always hear
the audio from the transceiver that is selected for transmit.
The users can identify which receivers are selected by noting which of the green switch LEDs are illuminated. Push buttons labeled Nav 1, Nav 2, MKR (Marker), AUX (auxiliary), and SPR (Speaker) are "momentary type switches. When one of these buttons is pressed, it will be active, and the LED will illuminate.
Press the switch again and it will be in the "off" position and remove that receiver from the audio.
If the aircraft is equipped with a DME or ADF, these audio sources can be selected with the AUX button.
3.4.1
Speaker Amplifier
The "SPR" in the push-button section stands for speaker. This switch will place all selected audio on the
cockpit speaker when this switch is selected.
NOTE: Except for the unswitched audio, the speaker amplifier is not active in the "Split Mode."
Unswitched audio, (autopilot disconnect, altimeter warning, etc.) will come through the speaker regardless
of the speaker button position.
3.4.1.1
Public Address Function
To access PA function, a switch is installed to connect the top connector, pin 18, to ground. This places the
pilot microphone on the speaker output (Pin W) when the PTT is pushed. The copilot can continue to use
the selected com radio.
We recommend that the switch transfer the audio from the cockpit speaker to a cabin speaker for public
address. This will prevent feedback.
3.4.2
Key “Click”
The SL15-CD is equipped with a “click” function that provides an aural feedback to the user in addition to
the tactile button push. This sound can be enabled or disabled by simultaneously holding the COM 1 and
COM 2 buttons in for at least 5 seconds. Any person hearing the radios will also hear the key click.

The split mode can be activated at any time by pressing the desired combination of XMT buttons. For instance, to activate a Com 1/Com 2 split, press and hold the com 1 button, and then press the Com 2 button
while holding the Com 1 button. This places the pilot on Com 1 and the Copilot on Com 2.
Split mode for Com 3, in normal (not TEL/Duplex) is possible with pilot on Com 1, copilot on Com 2 or 3.
Pilot on Com 2 or Com 3 and Copilot on Com 1 is not possible.
Note
Due to the nature of VHF communications signals, and the size constraints in general aviation
aircraft, it is probable that there will be some bleed-over in the Split mode, particularly on adjacent
frequencies. UPS Aviation Technologies makes no warranty about the suitability of Split Mode in
all aircraft conditions.
Note
Split Mode does not turn off other (Nav, ADF, etc.) selected audio to pilot. However, the copilot
will only hear the selected communications receiver.
3.5.1
Split Mode ICS
In split mode, the pilot and copilot are usually isolated from each other on the intercom, simultaneously
using their respective radios. Depressing the ICS button in Split Mode will activate VOX intercom between
the pilot and copilot positions. This permits intercommunication when desired between the crew. Pressing
the ICS button again disables this crew intercom function.
3.6
Intercom Operation
3.6.1
IntelliVox® VOX-Squelch
No adjustment of the IntelliVox® squelch control is necessary. There is no field adjustment. Through three
individual signal processors, the ambient noise appearing in all six microphones is constantly being sampled. Non-voice signals are blocked. When someone speaks, only their microphone circuit opens, placing
their voice on the intercom.
The system is designed to block continuous tones, therefore people humming or whistling in monotone may
be blocked after a few moments.
For consistent performance, any headset microphone must be placed within ¼-inch of your lips, preferably
against them. (ref: RTCA/DO-214, 1.3.1.1 (a)).
It is also a good idea to keep the microphone out of a direct wind path. Moving your head through
a vent air stream may cause the IntelliVox® to open momentarily. This is normal.
The IntelliVox® is designed to work with normal aircraft cabin noise levels (70 dB and above). It
loves airplane noise! Therefore, it may not recognize speech and clip syllables in a quiet cabin,
such as in the hangar, or without the engine running. This is normal.
For optimum microphone performance, UPS Aviation Technologies recommends installation of a Microphone Muff Kit from Oregon Aero (1-800-888-6910). This will not only optimize VOX performance, but
will improve the overall clarity of all your communications.

Intercom Volume Control
The volume control knob adjusts the loudness of the intercom for the pilot and copilot only. It has no effect
on selected radio levels, music input levels or passengers' volume level.
Adjust the radios and intercom volume for a comfortable listening level for the pilot. Most general aviation
headsets today have built-in volume controls; therefore, passenger volume can be adjusted at the headset. If
desired, passenger volume level can be adjusted by a screwdriver adjustment at the top of the tray (see figure 2-1).
3.6.2.1 Mono headsets in Stereo Installation
All passenger headsets are connected in parallel. Therefore, if a monaural headset is plugged in to a SL15CD Stereo installation, one channel will be shorted. Although no damage to the unit will occur, all passengers will lose one channel, unless they switch to the “MONO” mode on the headset. PS Engineering modifies headsets to add stereo capability, using high-fidelity speakers. Contact factory for details.
3.6.3
Intercom Modes
The lower switch on the left side is a 3-position mode switch that allows the pilot to tailor the intercom
function to best meet the current cockpit situation. The description of the intercom mode function is valid
only when the unit is not in the "Split" mode. Then, the pilot and copilot intercom is controlled with the ICS
button.
ISO: (Up Position): The pilot is isolated from the intercom and is connected only to the aircraft radio system. He will hear the aircraft radio reception (and sidetone during radio transmissions). Co-pilot will hear
passengers’ intercom and Entertainment 1, while passengers will hear copilot intercom and Entertainment 2.
Neither will hear aircraft radio receptions or pilot transmissions.
ALL: (Middle Position): All parties will hear the aircraft radio and intercom. Crew will hear Entertainment
1, passengers will hear Entertainment 2. During any radio or intercom communications, the music volume
automatically decreases. The music volume increases gradually back to the original level after communications have been completed.
CREW (Down Position): Pilot and copilot are connected on one intercom channel and have exclusive access
to the aircraft radios. They may also listen to Entertainment 1. Passengers can continue to communicate
with themselves without interrupting the Crew and also may listen to Entertainment 2.

SL15-CD Series Audio Selector Panel and Intercom System
Installation Manual
Anytime the SL15-CD is in either the COM 1/COM 2, COM 2/COM 1 ("Split Mode"), the pilot and copilot
intercom is controlled with the ICS button. The passengers will maintain intercommunications, but never
hear aircraft radios.
3.6.3.1
Entertainment Input
The audio selector panel has provisions for two separate entertainment input devices. The CD-15 remote
CD player is usually installed as Music 1, and feeds the pilot and copilot positions. They operate independently in the SL15-CD. The music volume control affects the CD-15 music level only in the pilot and copilot
positions.
While in the ISO (Isolate) mode, the copilot will hear Entertainment 1 while the four passengers will hear
Entertainment #2. The pilot will hear entertainment 1, at a muted level. In normal operation, whenever a
person speaks, or if the aircraft radio becomes active, the music will automatically mute and then will
gradually return to the original listening level when the intercom or radio conversation ceases.
When in the ALL mode, pilot and copilot will hear Entertainment 1 input while all passengers will hear the
Entertainment 2 source. While in the CREW mode, pilot and copilot will hear entertainment input #1 while
the passengers may listen to entertainment input #2.
It is also possible to use just the CD-15 as entertainment input device for both entertainment inputs. However, we suggest that a switch (DPDT) be installed between CD-15 entertainment input #1. This will allow
the pilot to direct the music as desired.
3.6.3.2 Soft Mute and Soft Mute inhibit
The Soft Mute feature assures that the aircraft radio transmissions will not be missed due to entertainment
playing. When there is radio reception or intercom conversation, the music level is dropped to a low, or
background level. When the radio or intercom traffic ceases, the level gradually returns to normal.
The front panel ICS switch controls muting of entertainment source #1 (for pilot and copilot). Pushing this
button places the ICS in Karoake (or sing along) mode, which inhibits the soft mute feature. This allows the
music to continue uninterrupted by intercom or radio traffic when cockpit workload is appropriate. Pushing
the button again will release the mute inhibit function.
The passenger music, source #2, can be placed in the Karoake mode if a remote switch is installed in the
aircraft. See wiring information for details.

Comments
This mode allows
the pilot to communicate without
the others bothered by the conversations. Copilot
and passengers
can continue to
communicate and
listen to music
This mode allows
all on board to
hear radio reception as well as
communicate on
the intercom. Music and intercom is
muted during intercom and radio
communications
This mode allows
the pilot and copilot to concentrate
on flying, while the
passengers can
communicate
amongst themselves.
Telephone Mode
The Com 3 mode can serve as a full duplex interface for telephone systems if the installation is correctly
configured. When interfaced with an approved airborne telecommunications system, the SL15-CD can serve
as a audio control and distribution center. Each intercom position has a "hook switch." The pilot's hook
switch is the "Com 3" button on the audio panel, the others are discrete switches mounted adjacent to the
headset jacks. When Com 3 is active in the duplex mode, the TX button will blink about twice as fast as the
normal transmit rate.
When the intercom is in ALL mode, the pilot can speak on the phone only if the Com 3 is selected for
transmit (Com 3 Xmt button activated). All intercom positions will hear the telephone conversation. If
any passenger places his or her switch into the “off-hook” position all passengers will also be heard on the
phone. All will hear selected audio. Com 1 audio is automatically heard in the headsets. The pilot and copilot will have transmit capability on the other selected transceiver Com 1 or 2, simply by using their respective PTT switch.
In CREW mode, the pilot and copilot are may use the telephone, with their respective hook switch (the
pilot selects Com 3 on the Xmt selector). Any passenger who places their switch into the off-hook position
will also have access to the phone, and all four passengers will hear the conversation.
In ISO intercom mode, when the SL15-CD is in the Com 3 mode, the pilot position is in the "Phone
Booth." Only the pilot will hear the telephone, and only he will be heard. He will also have access to Com 1
or 2, and will transmit on that radio using the PTT. All selected audio is provided. If any other passenger
goes “off hook” they will hear the phone.
Note
Because the cell phone uses an intercom circuit, all stations on that circuit will lose intercom capability when the cell phone is in use.

Compact Disc Operation
The two push buttons at the far right of the SL15-CD Option CD control the compact disk operation. Inserting the disc into the CD-15 remote player unit will automatically begin play.
The lower button (play/pause/advance) is used to play the disc from stop, pause play, and advance the track.
When the disc is stopped, pushing the button starts play. A short push will pause play. A longer press advances the track. Holding the button acts as a intro/scan, playing the first two seconds of each track until
released.
The top button is used to stop and eject the disc. Press momentarily to stop, press and hold to eject.
Figure 3-2 Stop/Eject Button
Figure 3-3 Play/Pause Advance Button
Pushing BOTH buttons momentarily will cause the CD to “back up.” If pushed in mid song, it will back up
to the beginning of the track. At the beginning of a song, it will go back to the previous track.
This “back-up” feature implemented with Software Release BBBB for units without IRS and FBBBB for
units with IRS and later. The software version is found on the side of unit by serial label.
Holding BOTH buttons in for more than two seconds will cause the CD player to power down.
NOTE: In order to restore CD operation you must cycle power on the SL15-CD.
3.9
Marker Beacon
The Marker Beacon Receiver uses visual and audio indicators to alert you when the aircraft passes over a
75 MHz transmitter.
The Blue lamp, labeled "O," is the Outer Marker lamp and has an associated 400 Hertz 'dash' tone. The
lamp and tone will be keyed at a rate of two tones/flashes per second when the aircraft is in the range of the
Outer Marker Beacon.
The Amber lamp, labeled "M," is the Middle Marker lamp and is coupled with a 1300 Hertz tone. It is
keyed alternately with short 'dot' and long 'dash' bursts at 95 combinations per minute.
The White lamp, labeled "I," is the Inner marker and has a 3000 Hertz 'dot' tone. The lamp and tone will be
keyed at a rate of six times per second.
The audio from the Marker Beacon Receiver can be heard by selecting the "MKR" push-button switch. To
adjust the volume level, there is a service adjustment located on the top of the unit.
A three-position switch is used to set the receiver sensitivity and to test the indicator lamps. Use "HI" sensitivity initially. This allows you to hear the outer marker beacon about a mile out. Then select the “LO”
sensitivity to give you a more accurate location of the Outer Marker. The momentary down switch position
is marker test, labeled "T/M" and illuminates all three lamps simultaneously to assure the lamps (internal
and external) are in working order. TST does not activate MM sense output.
Pressing the marker mode select down (to “T/M”) will cause the marker audio to mute for that beacon. The
next beacon received will re-activate the audio.

SL15-CD Series Audio Selector Panel and Intercom System
Installation Manual
Appendix A External PTT Hook Up
Part of the installation includes the installation of PTT (Push To Talk) switches that allow the use of your
aircraft radio for communications transmissions.
There are three configurations that can be used, you must select the case that best fits your installation.
NOTE
Only the person who presses their PTT switch will be heard over the radio.
CASE I
The PTT is built into the pilot and copilot yokes
Simply install the plugs from the headset into the aircraft headphone jacks. Then use the yoke mounted PTT
to transmit. No other action is required.
CASE II
Built in PTT only on the pilot side only
This configuration requires a modified external PTT switch plugged into the copilot's mic jack. (See Details
Below) When the copilot's PTT is depressed, this activates an internal relay that switches the mic audio to
the aircraft radio from the pilot to the copilot.
Case III
No built in PTT switch at all
Two built-in PTT must be installed, or two external, modified PTT switches will be required for both the
pilot and copilot. Modifications to the PTT are required. (See details below)
Push To Talk Modifications
When received from the manufacturer, an after-market PTT switch opens the mic audio path to the "ring"
connection of the PTT mic plug until the button is pressed. When the PTT is between the intercom and the
headset, the intercom function will not work unless the PTT switch is depressed. A simple modification can
be performed to allow proper intercom operation. NOTE: This mod does not alter normal operation.
Below are some examples of typical modifications. Contact the PTT manufacturer for more details if necessary.
Procedures For David Clark PTT
Unscrew the round black plastic cover from the jack.
Connect the joined black wires to the red wire.
