Pilot USA PA-1771Th ANR Helicopter Headset
MFR Model# PA-1771TH
Overview
|
Utilizing the same electronics as the PA-1779TH, the PA-1771TH comes with an external battery pack (one 9V). For added comfort, the headset comes standard with a Genuine Sheepskin head pad and their proprietary Twin-layer Silicone Gel Ear Seals (30% less weight than normal gel ear seals). The weight has been brought down to 11.9 oz. on this model making it one of the lightest weight ANR headsets in the marketplace. The PA-1771TH is equipped with their new Auto On/Auto Shut-off proprietary circuitry. The ANR will automatically turn on when plugged into an aircraft with the radio turned on or plugged into an active intercom. The headset will shut-off automatically when the headset is unplugged from the inline battery box or is manually turned off using the On/Off button on the battery box. The headset will also automatically turn off when the radio or master switch is turned off. This headset is featured with their cell/satellite phone capability using an input jack. The input jack serves a dual purpose so that the user can listen to music from a CD player, IPOD®, MP3® or external radio and listening to “True Stereo” through the same jack. A custom protective padded case is provided with the headset. |
