1.3 Description

The IntelliPAX (11606) is an intercom expansion unit with intercom volume control for the passengers. This unit is designed to work in combination with the PMA7000-Series audio panel. It contains PS Engineering’s proprietary intercom protocol, IntelliVox®. This system uses digital processing on each of the six individual microphones to eliminate manual squelch adjustments. Because of the automatic squelch, the unit can be blind mounted, and the 11606R is designed to be remote-mounted, with the volume control removed. The volume control is factory set for optimum level. Part numbers, 11616 and 11616R units are designed to be used with other intercoms such as the PM1000II (11902, 11922, 11906), intercoms, and specifically modified PM1200 intercoms to provide up to 6 additional passenger stations.

The 11606-SA is a stand-alone passenger intercom unit, that can be single (6-passengers) or Dual (12passengers).

The Part Number 11626 (11626R) is specifically designed for use with the PM1000-DAP, allowing entertainment in the expansion unit, while not available in the crew portion.

The part number “R” version is designed for remote, or blind mounting.

The part number 11636R is for expanding the PMA8000D system to 6 or 12 places. This unit is only available as a remote unit.

1.4 Approval Basis NONE

None. It is the installer’s responsibility to determine the applicable approval basis for this installation. This unit is not designed for use in any flight crew situations, and has no effect on any critical aircraft systems. There is no significant weight or electrical load presented to the aircraft.

Section II – Installation

2.1 General Information

The IntelliPAX comes with all necessary hardware for a typical installation. The unit is installed either in the panel (11606, 11616, 11626) or mounted blindly (11606R, 11616R or 11626R). If panel mounted, it can be installed near the main unit, or near the passengers. If blind mounted, it can be mounted nearly anywhere. The 11606R and 11616R volume control for the passengers is factory set for a balanced output, but can be field adjusted through the holes in the side of the unit.

Installation of the IntelliPAX, using the available wiring and hardware supplied, does not require special tools or knowledge other than described in 14 CFR 65.81(b) and FAA Advisory Circular 43.13-2B

It is the installer's responsibility to determine the approval basis for this installation. An FAA Form 337, or other approval may be required. See Appendix B for example of FAA Form 337.

2.2 Unpacking and preliminary inspection

The IntelliPAX was carefully inspected mechanically and thoroughly tested electronically before shipment. It should be free of electrical or cosmetic defect.

2.3 Equipment installation procedures

2 ea. 0.125

2.40”

NOT TO SCALE

For panel mounted installation (11606, 11616, 11626)

1. Using the template, drill three holes in the instrument panel in a location convenient to the pilot or

passengers position(s).

2. Insert the IntelliPAX from behind the instrument panel, aligning the holes for the knobs.

3. Place the aluminum faceplate over the knob shaft and secure, using the two # 4-40 round head screws

provided.

4. Install the volume knob over the volume control shafts.

Blind mounting: (11606R, 11616R, 11626R, 11606-SA 11636R)

1. Install the unit on an avionics shelf or other appropriate structure.

2. If desired, the volume can be adjusted at installation, there are two holes in the side of the unit, one

for left, and another for right channel.

3. If desired, a remote switch (not included) can be installed to override the SoftMute™ function. This

should be located convenient to the passengers.

2.4 Cable harness wiring

To complete the installation, a wire harness must be made as shown in Appendix C. PS Engineering can make a custom-tailored wiring harness for the installer. All harnesses use Mil-spec quality components with professional techniques, and are fully tested before shipment. Contact PS Engineering for more information. The IntelliPAX connects to the main unit through a 4- or 5-conductor, shielded cable.

2.4.1 Electrical Noise Issues

WARNING: You must use separate shielded cables for the microphone and headphone jacks. Combining

these two wires WILL cause loud oscillations and degrade the intercom function. The oscillation is caused

by the cross-coupling between the large headphone signal and the small microphone signal. The resulting

feedback is a high-pitched squeal that varies with the volume controls.

Shielding can protect the system from radiated noise (rotating beacon, power supplies, etc.). However, installation combinations occur where minor interference is possible. The IntelliPAX was designed in an interference -protected chassis and has internal filter capacitors on all input lines.

Ground loop noise occurs when there are two different return paths for the same signal, such as airframe and ground return wire. Large cyclic loads such as strobes, inverters, etc., can inject audible signals onto the airframe return path. Follow the wiring diagram very carefully to help insure a minimum of ground loop potential. Radiated signals can be a factor when low level mic signals are bundled with current carrying power wires. Keep these cables separated.

Insulating washers are required on all mic and headphone jacks to isolate them from aircraft ground.

2.4.2 Power Requirements

The IntelliPAX was designed to work with the main intercom unit. No other power is required.

The Stand Alone unit is connected to a 1A breaker to the avionics bus (2A for dual).

2.4.3 Interconnection with main unit

Interface between the IntelliPAX and the main intercom is through a 4-wire shielded cable.

On the PMA8000D, the expansion is connected to the copilot’s audio panel, except for paralleling pin 3 to the pilot audio panel. The PMA8000D can support two expansion units, for up to 12 passenger stations.

2.4.4 Auxiliary Inputs

An entertainment device can be connected to the IntelliPAX. Install a 1/8" music jack convenient to the passengers to connect the stereo entertainment device into the system. A "Soft Mute" system is installed in the IntelliPAX that will mute the music during conversation on the local intercom. Radio traffic or conversation on the main intercom will not mute the music.

A second, monaural input is provided for other purposes, such as public address cabin briefing, or providing radio interface for cases where the intercom does not have radio on the expansion bus (PM1000D for example).

NOTE:

The PM1000D is not compatible with a music input, due to the specialized interface nature. If this is

used, connect the entertainment input to the IntelliPAX (11626) alone.

A soft mute inhibit switch (not included) can be installed between IntelliPAX connector pins 12 and 24. Closing this switch places the IntelliPAX into Karoake mode.

WARNING: Local oscillators and other internal signals from CD or radio equipment can cause undesired

interference with VHF navigation and communication equipment. Before takeoff, operate the

entertainment device to determine if there is any adverse effect on aircraft systems. If any unusual

operation is noted in flight, immediately switch the entertainment device off.

2.5 Post Installation Checkout

After wiring is complete, verify power is ONLY on pin 1 of the connector, and ground on pin 14 (with main unit operating. Failure to do so will cause serious internal damage and void PS Engineering's warranty. With all units plugged in and operating, verify that all active stations can communicate on the intercom, and that any music sources are present, and the SoftMute inhibit control operates correctly (if installed).

Section III – OPERATION

3.1 Power

Switching on the intercom or audio panel automatically activates the IntelliPAX unit. The Stand Alone unit is active when power is applied to the Avionics Bus.

3.2 Adjusting the Volume

For the P/N 11606R, operating with a PMA7000B or copilot’s PMA8000D, the audio panel’s Passenger volume control (PASS) affects the expansion intercom volume.

The 11616 volume control only affects the headsets connected to the IntelliPAX directly, and not the main unit. The Remote (11616R) versions have a service adjustable volume, which is accessible through a pair of openings on the side of the unit. These are 20-turn potentiometers, so may require many turns to make a difference. The volume is set to maximum at the factory. Users can reduce the volume at individual stereo headsets.

When combined with a PAC24, the expansion volume should be set near minimum, and the copilot knob on the PAC24 should be used to adjust the volume.

In the remote 11606-SA (stand alone) units, the volume is a service adjustment, set at maximum, so the headset volume can be used.

3.3 IntelliVox® Squelch

No adjustment of the IntelliVox® squelch control is required or possible. Through independent processors on each microphone, the ambient noise appearing in all microphones is constantly being sampled. Nonvoice signals are blocked. When someone speaks, only their microphone circuit opens, placing their voice on the intercom.

For best performance, the headset microphone must be placed within ¼ inch of your lips, preferably against them. 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.

PS Engineering, Inc. recommends installation of a Microphone Muff Kit from Oregon Aero (1-800-888-

6910). This will optimize IntelliVox® performance.

3.4 Music Mute

If a remote switch is installed between pins 12 and 24, the “SoftMute” will be enabled. When the switch is closed, the music will mute whenever there is intercom conversation in the IntelliPAX. Audio coming from the main unit, such as radio or intercom, will not mute the IntelliPAX music.

Opening the switch places the unit music, “Karaoke Mode,” and music muting is inhibited.

For the 11606 and PMA7000-Series, intercom audio in the expansion unit will not mute music in the audio panel.

For the PMA8000D, the music sources connected to the copilot’s audio panel are fed into the expansion unit, and if the expansion unit music is also playing, BOTH sources will be heard. Refer to the PMA8000D installation manual for more information.
