The Stratus 30 has passive noise reduction of greater than 29dB and active noise reduction (ANR) of up to 13dB.
Dented slide adjustment on the headband allows the ear cup to be easily raised or lowered for proper fit. Yoke design allows the ear cup to pivot in two planes assuring proper seal to the head and distributing ear cushion pressure evenly over its entire surface. Ear cup pressure can be adjusted through use of the patented ComfortCam™.
The amplified electret noise-cancelling microphone eliminates unwanted cabin noise from entering the communication system. The boom rotates up to allow it to be worn on either side of the head. Retaining hooks designed into the microphone housing securely hold the windscreen in place.
All cables are shielded to protect against RFI. Strain relief is added to all cord entry points to provide protection from tugging. Bend relief is added at high-flex cord entry points to protect cords from breakage due to bending. Separate receiver and microphone plugs for plugging into the aircraft radio/intercom system are included. Cables with plugs for use with cell phones, cd players, and mp3 players are also included.
The headset will shut off automatically after 15 minutes in low-noise environments. When Auto Shut-Off is enabled, things that keep the headset on are communication over the aircraft radio/intercom system, cell phone conversations, listening to music, and cabin noise greater than 90dB.
The module puts most commonly used controls at the pilot's fingertips. There is a cell phone jack to connect the phone and headset. An auxiliary input jack allows for listening to cd and mp3 players through the headset. The power on/off button will turn on and off all functions to and from the headset except for to and from the radio/intercom system. The accessory mute button quickly and completely disables the cell phone and auxiliary audio devices while maintaining radio/intercom communication. The LED indicates which functions are in use as well as low battery. The batteries are recharged through the DC input jack.
