Submersible – Waterproof up to 3 feet, for 30 minutes, salt water survivable.Noise Reduction Rating (“NRR”) of 25 DB.
Active-Volume Function – When the active-volume function is on, the amplification is reduced when an external signal is received, i.e., radio transmission.Polarity Protection – prevents damage to circuits if the batteries are inserted incorrectly.Two warning signals are emitted to indicate that the unit will switch off in one minute if no function is activated. Automatic Shut-off – after two hours of no active functions the unit automatically powers off to conserve battery power.Last setting memory – This feature ensures that the latest settings are stored at shut-off.Meets Environmental Standard MIL-STD-810F.Ambidextrous noise-canceling boom mic –The flexible goose neck boom mic can be switched to either side for both left and right handed shooters.When the headset batteries die, the comms circuitry draws power from the radio unit. In more relevant terms, this means that should the batteries on your headset die, radio coms are not interrupted. Autonomous sound amplification and comm circuitry – external communications and stereo “talk-thru” are independent of each other meaning that you can listen to an external signal without battery power and even when the product is switched off.The Level-Dependent digital audio circuit senses noise levels above the desired threshhold and compresses them to a safe decibel level or amplifies weak sounds to an audible level. A microphone receives the sounds outside the headset and transmits them to a speaker inside the headset. This is accomplished with a proprietary digital audio circuit integrated into the headset. Environmental Listening) Environmental Listening is a means of allowing safe audio sounds to bypass the individual hearing protection while still protecting against harmful noises. Environmental Listening – Level-dependent surround sound for “talk-thru” function ( aka.While this write-up is not intended to be direct comparison between the Sordins and the Com-Tacs given that these two products are considered top tier for this category and are both widely fielded by Military units and LEO Tac Teams worldwide I feel that it would be a fair comparison.Īs most of our readers, I am sure, are already grossly familiar with the Com-Tacs I will be skimming over many of the nomenclature and a few other things that can be considered common knowledge and will focus more on my personal findings and observations. Prior to writing this I have been using an MSA Sordin Supreme Pro neckband version which I will refer to from time to time to provide a reference point to compare these to. I recently acquired a Peltor Com-Tac headset and I thought I would do a short write-up about them. 3M/Peltor Com-Tac II MT15H69FB-19 ( dual comm)
