PA-1161T Passive Headset Manual
Fitting Your Headset
Wearing your headset properly is paramount to achieving both comfort and noise attenuation.
First slightly loosen the hand adjustable knobs on the headband. The headset should be placed
on your head and slowly pulled down so that each ear cup is properly positioned over each ear
for maximum noise attenuation. Tighten the knurled knobs when the headset feels correct.
It should apply slight pressure on your head without being snug. You may need to make your
final adjustments in the high noise environment of the cockpit.
Microphone Placement
Your headset comes with a ratcheting half metal/half flexible “memory” microphone boom and a
noise canceling electret microphone. The boom can be rotated 360 degrees for left or right side
use. Proper placement of the electret microphone is critical in order to achieve clear
communications. The microphone should be placed at the corner of the mouth approximately
1/4” away from the lips.
Volume Control
The OEM Passive is fitted with 2 individual volume controls, one on the right ear cup dome and
one on the left side of the dome. When adjusting the volume control, the pilot-in-command
should adjust their volume control first with the audio system turned on. Please remember that
you may be dealing with 3 volume controls - radio, intercom and headset.
Mono/Stereo Selector (On Comm-cord splitter)
Your headset comes standard with a Mono/Stereo selector switch which is located on the
comm-cord splitter. “M” indicates the mono position while “S” indicates the stereo position. It
should be noted that if you are using a monaural intercom and your headset is set in the stereo
position, you will only hear through one speaker on your headset. With a stereo intercom, you
will hear true stereo if the selector switch is set to the stereo mode position.
Cell/Satellite Phone Capable
Having the capability in an emergency of being able to place a cell phone call from your aircraft
is one of the reasons we have installed a Cell/Satellite jack on the headset. Located on the non-
boom side ear cup, a 2.5mm jack has been installed. It will work with 90% of cell phones in the
marketplace. An adapter may need to be purchased from your local electronics shop in order to
utilize this feature.
Music Input Jack
The Cell/Satellite Phone Jack can also be used as a Music-Input jack. Plug in your favorite
music source, IPOD®, MP3® or CD player and you’ll hear true stereo music in your stereo
headset.
Half Liquid / Half Foam Ear Seals
Your headset is fitted with our premium half liquid / half foam ear seals. The ear seals are
outstanding in noise canceling due to the combination of liquid and foam in the ear seals which
