THE DOMINATOR II COMMS SUITE

The DOMINATOR II was developed with a U.S. Naval Special Warfare team in an effort to overcome issues they were having with other

communication systems on the market. Prior to the DOMINATOR project, most of the comms systems available forced the operator

to have something in, on or over one or both ears to communicate. Many of the systems required earpieces to be worn in both ears to

both RX and TX. Furthermore, most of those same systems required the use of batteries inside the push-to-talk coupled with software

that required periodic updating via connection to a PC. Other systems required ear cups to be positioned and worn over both ears for

radio RX. Our client complained about issues with these various designs including ear fatigue, sweat filling the ear canals, less than

clear transmitted comms by systems using an in-the-ear microphone for TX and dissatisfaction with the quality of amplified ambient

environment (situational and directional awareness) as compared to SA and DA from natural hearing. The DOMINATOR development

project began in May of 2009 and satisfactory completion was not realized until December of 2012 - a project that required nearly 3.5

years of development, design/re-design and test and evaluation in both the U.S. and in theatre.

The DOMINATOR II combines a waterproof/noise canceling boom microphone for TX while utilizing both bone conductors and

electronic earpieces for radio RX. The bone conductors and electronic earpieces work independently of one another as well as in

concert when operational requirements call for the implementation of hearing protection. The electronic earpieces are capable of

performing three functions: a. Radio/ICS/Smartphone/MP3 Reception b. Electronic Hearing Protection c. User Controlled Ambient

Environment Amplification. When hearing protection is not required, the earpieces can be removed from the ears and stowed out of the

way via a magnet assembly on each earpiece cable. Radio RX is maintained without the use of the electronic earpieces via twin bone

conductors integrated into the headset. Radio transmissions are received via the facial bones directly in front of each ear and passed

via bone conduction to each inner ear canal. The DOMINATOR II is available in both single and dual comm radio models and features

a broad mix of mission-specific accessory cables as well as connectors for the most fielded military radio platforms. A wireless, gun

mount remote push-to-talk control is also available.

The DOMINATOR II met the requirements of the U.S. NSW client, including a simple to use plug and play design, the ability to engage

and disengage hearing protection at will, little or no maintenance, no main push-to-talk batteries or software upgrades as well as not

having something in, on or over the ears at all times to maintain RX and TX capabilities. A team-wide purchase was made in early

2013.

PROPERLY FITTING THE

DOMINATOR II HEADSET TO YOUR HEAD

Undo the adjustable rear Velcro strap and position the stainless steel DOM II frame over the top of your head. Grab ahold and

position the two individual sidepiece housings (containing the bone conductors and earpieces) of the headset directly in front

of each ear. Release the sidepiece housings, if your headset frame is the proper size (S-XL) the sidepiece housings should

remain in place directly in front of your ears lying across the cheek bones (think of each sidepiece as a 'sideburn'). If the

sidepiece housings slide downward after you release them and are no longer positioned on the cheek bone, in front of the ears,

your frame length is too long. Likewise, if you position the headset on your head and the sidepiece housings orient themselves

above the cheek bones when released - your frame length is too short. As mentioned earlier, the DOM II is available in 4 frame

lengths (S-XL) - it is crucial that you have the proper size frame in order to take full advantage of the unique capabilities of bone

conduction reception. Look closely on the inside portion of the headset that lies against your face -- you will see a laser etched

letter (S-XL) that will denote the size of headset you have.

The DOMINATOR II nylon head strap separates for adjustment. One end of each strap features a steel snap designed to

encircle and lock down on the stainless steel frame of the headset. One of the opposite strap ends features sewn hook Velcro

while the other strap features its sewn loop counterpart. When attached together, the strap provides a stabilizing effect for

the headset to prevent unwanted rearward or forward movement. When properly adjusted, the sidepiece housings of the

DOM II should be directly in front of each ear and directly across each cheek bone. There should be little forward or rearward

movement of the headset once the rear head strap is adjusted properly

DOM II BOOM MIC

The DOMINATOR II headset features a waterproof, noise-

canceling boom microphone as the method of voice transmission.

The microphone arm is manufactured from flexible brass covered

in a durable neoprene jacket allowing the operator to position the

microphone element, at the end of the boom arm, at the most

advantageous degree for voice transmission. The DOM II boom

microphone features twin elements, one that points away from

the mouth and face when properly positioned and the other that

points directly toward the mouth and face. When a push-to-talk

button is depressed on the control box, the microphone element

pointing away from the mouth/face, picks up the noise in the

operator's ambient environment and cancels it out - preventing

it from being transmitted to other operators on the same radio

frequency. This allows the voice transmission being picked up by

the element facing the mouth and face to be clear and concise

when transmitted to others. Many systems on the market utilize

an in-the-ear bone microphone for picking up the operator's

voice and transmitting it to others. Our client believed in-the-ear

transmissions to sometimes be garbled, impacted by sweat in the

ear canal and generally less than reliable - particularly in high

noise environments such as helos. Furthermore, the operators did

not want to have something positioned in the ear(s) the entire time

to maintain radio, phone and ICS comms. A high-quality, noise

canceling boom microphone overcomes those obstacles - thus

one of the main reasons it was utilized in the DOM II's design.

As shown in the pictures and previously described, the bone conductors should be positioned directly in front of each ear

for proper radio RX. With the earpieces positioned properly - the attached, black concha bow should be bent forward as the

earpiece is inserted into the ear canal. The patented concha bow acts as a stabilizer, holding the earpiece firmly in the proper

position to ensure clear and consistent reception of incoming comms as well as maintaining a proper seal to protect the user's

hearing. As a reminder, the bone conductors ONLY receive incoming radio comms. The electronic earpieces receive radio

comms PLUS smartphone, MP3 and ICS comms - also providing ambient amplification and level dependent electronic hearing

protection.
